What to Expect During Your Exam
Exam Overview
To document the nature, severity, and functional impact of ankle ankylosis for VA disability rating purposes under 38 CFR 4.71a, Diagnostic Code 5270. Ankylosis means the ankle joint is abnormally stiff, immobile, or fused - either from disease, injury, or surgical fusion. The examiner must determine the position of the ankle at fusion (plantar flexion, dorsiflexion, or neutral) and whether any deformity (abduction, adduction, inversion, eversion) is present, as these factors directly determine the rating percentage.
What the examiner evaluates:
- Confirm diagnosis of ankle ankylosis (complete or near-complete loss of ankle joint motion)
- Determine the degree and direction of the fixed position: plantar flexion angle (in degrees), dorsiflexion angle (in degrees), or neutral
- Identify presence of deformity: abduction, adduction, inversion, or eversion
- Active range of motion (ROM) of the affected ankle - dorsiflexion and plantar flexion
- Passive range of motion - examiner manually moves the joint to detect any residual motion
- Weight-bearing versus non-weight-bearing ROM differences
- Pain on motion, at rest, and with repetitive use (DeLuca factors)
- Functional loss caused by ankylosis: disturbance of locomotion, interference with standing or sitting
- Muscle atrophy or weakness in the affected extremity
- Assistive devices used (cane, brace, crutches, walker, wheelchair)
- Surgical history: ankle arthroscopy, total ankle replacement, talectomy, or prior ankle fusion procedures
- Diagnostic imaging findings (X-ray, MRI, CT) confirming ankylosis
- Impact on daily activities, employment, and overall functional status
Exam typically occurs at a VA medical center, a VA-contracted facility (e.g., LHI/OptumServe, QTC), or via telehealth. In-person physical examination is strongly preferred and expected for ankle ankylosis because range-of-motion and deformity assessment are physically measured. You have the right to request recording of the examination in most states. Bring a support person if needed but notify staff in advance.
Typical duration: 20-30 minutes
Active Dorsiflexion Range of Motion
How far you can pull your foot upward toward your shin under your own muscle power, measured in degrees from neutral (0-). Normal active dorsiflexion is approximately 20-.
What to expect:
The examiner will ask you to sit or lie on the exam table and flex your foot upward as far as possible while they observe or use a goniometer to measure the angle. For true ankylosis, motion will be severely restricted or absent. They will record the starting and ending position.
Key thresholds:
- Dorsiflexion fixed at more than 10- (e.g., foot angled upward beyond 10-) — 40% rating - unfavorable position
- Dorsiflexion fixed between 0- and 10- — 30% rating
- Plantar flexion fixed at more than 40- (foot pointed downward beyond 40-) — 40% rating - unfavorable position
- Plantar flexion fixed between 30- and 40- — 30% rating
- Plantar flexion fixed at less than 30- — 20% rating
- Any abduction, adduction, inversion, or eversion deformity present — 40% rating regardless of plantar/dorsiflexion angle
Tips:
- Do not force extra motion during testing - allow your natural, honest range to be recorded.
- If pain prevents full effort, tell the examiner immediately: 'I am stopping because of pain at this point.'
- Perform the motion as you would on a typical day, not your absolute best effort on a single good day.
- Ask the examiner to record both the starting position and the endpoint of motion for each direction.
Pain considerations: Under DeLuca v. Brown, the examiner must consider and document whether pain limits motion before the anatomical endpoint is reached. If you feel pain before reaching maximum range, verbally state 'I have pain now at approximately this point' so the examiner documents it. Pain on motion - even if some motion remains - is a compensable functional loss factor.
Passive Dorsiflexion and Plantar Flexion (Correia Requirements)
Residual motion when the examiner physically moves your foot without your muscular effort. In true ankylosis, passive motion will also be absent or severely limited. Passive ROM may exceed active ROM when pain or muscle weakness limits effort but joint motion is possible - or may equal active ROM in true bony fusion.
What to expect:
The examiner gently holds your foot and attempts to move it in each direction. You should relax your ankle muscles completely. They will compare passive ROM to active ROM and document any difference. For true ankylosis, expect both to be near zero or fixed at the ankylosed angle.
Key thresholds:
- Passive ROM equals active ROM — Confirms true ankylosis or severe structural restriction - supports ankylosis rating under DC 5270
- Passive ROM significantly exceeds active ROM — May suggest limitation is pain-based or muscle-based rather than true bony ankylosis - examiner should document DeLuca factors
Tips:
- Relax your ankle completely during passive testing - do not resist or assist the examiner's movement.
- If passive motion causes pain, say so immediately and describe its location and intensity.
- Passive ROM should be measured in both weight-bearing and non-weight-bearing positions per Correia requirements when applicable.
Pain considerations: Pain during passive motion is equally important to document. Tell the examiner if passive movement causes pain even if the range of motion appears similar to active. This is relevant to the overall functional loss assessment.
Weight-Bearing vs. Non-Weight-Bearing Assessment (Correia Requirements)
Whether your ankle's restricted position or residual motion changes when you are standing and bearing weight versus lying down or seated. Many ankle conditions worsen under load.
What to expect:
The examiner may assess your ankle while you are standing (weight-bearing) to observe alignment, deformity, and any dynamic changes. They may also observe your gait. This is then compared to seated or lying-down measurements.
Key thresholds:
- Deformity worsens or becomes more pronounced with weight-bearing — Supports higher severity rating; documents real-world functional limitation
- Gait disturbance observed on weight-bearing — Supports disturbance of locomotion finding, relevant to functional loss documentation
Tips:
- Walk naturally for the examiner - do not try to mask your gait abnormality.
- Describe any changes in your symptoms when standing for prolonged periods versus sitting.
- Mention any falls, near-falls, or instability when standing or walking on uneven surfaces.
Pain considerations: Describe how weight-bearing specifically affects your pain level. For example: 'When I stand for more than 10 minutes, my ankle pain increases from a 4 to an 8 out of 10, and I must sit down or use my cane.'
Deformity Assessment (Abduction, Adduction, Inversion, Eversion)
Whether the ankylosed ankle is fixed in an abnormal sideways or rotational position, in addition to the forward/backward (plantar/dorsiflexion) plane. Any such deformity automatically places the rating at 40% regardless of the plantar/dorsiflexion angle.
What to expect:
The examiner will visually inspect and manually assess whether your foot deviates inward (inversion/adduction) or outward (eversion/abduction) from the neutral straight-ahead position. They will document the type and approximate degree of deformity.
Key thresholds:
- Any abduction deformity present (foot turns outward) — 40% rating under DC 5270
- Any adduction deformity present (foot turns inward) — 40% rating under DC 5270
- Any inversion deformity present — 40% rating under DC 5270
- Any eversion deformity present — 40% rating under DC 5270
Tips:
- Bring imaging (X-rays, CT scan, MRI) that shows the ankylosed position and any deformity to the exam.
- Mention to the examiner if your foot appears to turn inward or outward when you stand - ask them to specifically assess and document this.
- If a prior surgical report describes the position of fusion, bring it to the exam.
Pain considerations: Deformity often causes secondary pain in the knee, hip, and lower back due to compensatory gait changes. Mention all secondary musculoskeletal complaints that began after your ankle became ankylosed.
Muscle Atrophy Measurement
Circumference of the calf and lower leg muscles compared to the unaffected side, measured in centimeters. Disuse atrophy occurs when an ankylosed ankle prevents normal muscle use.
What to expect:
The examiner may use a tape measure to compare the circumference of both calves at the same point above the ankle. A difference of more than 1-2 cm is clinically significant and supports functional loss documentation.
Key thresholds:
- Measurable circumference difference between affected and unaffected calf — Supports functional loss finding; contributes to overall disability documentation
Tips:
- Wear shorts or loose-fitting pants so both calves can be measured without restriction.
- Do not flex your calf muscles during measurement - relax them.
- Mention to the examiner if you have noticed your affected leg looks thinner than the other.
Pain considerations: Atrophy itself is not painful, but weakness from atrophy causes increased fatigue and instability. Describe how the weakness of your affected leg contributes to your overall functional limitations.
Repetitive Use Testing / DeLuca Factors
Whether your ankle range of motion, pain, weakness, fatigue, or coordination worsens after repetitive use (e.g., after walking, after prolonged standing). Under DeLuca v. Brown, the examiner must assess and document functional loss due to pain, weakness, fatigue, lack of endurance, and incoordination - not just the static ROM measurement.
What to expect:
The examiner should ask about your condition after activity or over the course of a day. They may ask you to perform a motion repeatedly and assess for worsening. For ankylosis, static measurements may look the same before and after, but pain and fatigue with use are critical functional loss factors.
Key thresholds:
- Increased pain after repetitive use documented — Supports additional functional loss; prevents underrating based on static ROM alone
- Fatigue, weakness, or incoordination documented after use — Required DeLuca factor for accurate functional loss assessment
Tips:
- Proactively tell the examiner: 'After walking one block, my ankle pain increases significantly and I need to rest - please document this as a DeLuca factor.'
- Describe your worst days, not your best days - the VA rates based on the full spectrum of your disability.
- Mention any days when your condition flares up and prevents you from performing normal activities.
Pain considerations: Pain with activity is a DeLuca functional loss factor even when it does not change the measured ROM. Always state whether your pain increases with use and how long it takes to recover after exertion.
Rating Criteria Breakdown
| Rating % | Criteria | Key Symptoms |
|---|---|---|
| 40% | Ankle ankylosed (fixed/fused) in plantar flexion at MORE than 40 degrees (foot severely pointed downward), OR in dorsiflexion at MORE than 10 degrees (foot excessively angled upward), OR with any abduction, adduction, inversion, or eversion deformity present. These are all 'unfavorable' positions because they cause significant gait disturbance and functional limitation. |
CFR: Per 38 CFR 4.71a DC 5270: 'In plantar flexion at more than 40-, or in dorsiflexion at more than 10- or with abduction, adduction, inversion or eversion deformity - 40%.' A foot fused in severe equinus (toes pointing sharply downward) or fused while turned sideways represents an unfavorable ankylosis. |
| 30% | Ankle ankylosed in plantar flexion BETWEEN 30 and 40 degrees (moderate downward-point), OR in dorsiflexion BETWEEN 0 and 10 degrees (slight upward tilt). These are intermediate positions - less functional than neutral but not as severely disabling as the unfavorable extremes. |
CFR: Per 38 CFR 4.71a DC 5270: 'In plantar flexion, between 30- and 40-, or in dorsiflexion, between 0- and 10- - 30%.' A foot fused with the toes pointing moderately downward, requiring a heel lift or brace to walk, typifies this level. |
| 20% | Ankle ankylosed in plantar flexion at LESS than 30 degrees (mild or near-neutral downward position). This is considered the most 'favorable' ankylosed position because the foot is close to neutral and can still bear weight with less compensatory adjustment required. However, it is still a complete fusion of the ankle joint. |
CFR: Per 38 CFR 4.71a DC 5270: 'In plantar flexion, less than 30- - 20%.' A foot fused in a nearly neutral position (slightly toed-down) where the veteran can walk with a modified gait but has no ankle motion whatsoever. |
40% Ankle ankylosed (fixed/fused) in plantar flexion at MORE tha ...
Ankle ankylosed (fixed/fused) in plantar flexion at MORE than 40 degrees (foot severely pointed downward), OR in dorsiflexion at MORE than 10 degrees (foot excessively angled upward), OR with any abduction, adduction, inversion, or eversion deformity present. These are all 'unfavorable' positions because they cause significant gait disturbance and functional limitation.
Key Symptoms
- Foot fixed in severe downward-pointed position (equinus/plantar flexion >40-)
- Foot fixed in excessive upward tilt (dorsiflexion >10-)
- Foot turned outward (eversion/abduction deformity)
- Foot turned inward (inversion/adduction deformity)
- Significant gait disturbance requiring assistive device
- Inability to walk on flat ground without compensation
- Severe functional limitation in standing, walking, climbing stairs
CFR: Per 38 CFR 4.71a DC 5270: 'In plantar flexion at more than 40-, or in dorsiflexion at more than 10- or with abduction, adduction, inversion or eversion deformity - 40%.' A foot fused in severe equinus (toes pointing sharply downward) or fused while turned sideways represents an unfavorable ankylosis.
30% Ankle ankylosed in plantar flexion BETWEEN 30 and 40 degrees ...
Ankle ankylosed in plantar flexion BETWEEN 30 and 40 degrees (moderate downward-point), OR in dorsiflexion BETWEEN 0 and 10 degrees (slight upward tilt). These are intermediate positions - less functional than neutral but not as severely disabling as the unfavorable extremes.
Key Symptoms
- Foot fixed in moderate downward position (plantar flexion 30-40-)
- Foot fixed in slight upward position (dorsiflexion 0-10-)
- Moderate gait disturbance - able to walk with compensation
- Difficulty on stairs, uneven terrain, prolonged standing
- May require brace or supportive footwear to ambulate
- Chronic pain with activity
CFR: Per 38 CFR 4.71a DC 5270: 'In plantar flexion, between 30- and 40-, or in dorsiflexion, between 0- and 10- - 30%.' A foot fused with the toes pointing moderately downward, requiring a heel lift or brace to walk, typifies this level.
20% Ankle ankylosed in plantar flexion at LESS than 30 degrees ( ...
Ankle ankylosed in plantar flexion at LESS than 30 degrees (mild or near-neutral downward position). This is considered the most 'favorable' ankylosed position because the foot is close to neutral and can still bear weight with less compensatory adjustment required. However, it is still a complete fusion of the ankle joint.
Key Symptoms
- Foot fixed in mild downward position (plantar flexion <30-)
- Near-neutral fusion - foot nearly flat but completely immobile
- Able to ambulate without major gait deviation in some cases
- Chronic pain with prolonged standing or walking
- Fatigue of the affected leg with extended activity
- Compensatory knee, hip, or back pain due to altered gait
CFR: Per 38 CFR 4.71a DC 5270: 'In plantar flexion, less than 30- - 20%.' A foot fused in a nearly neutral position (slightly toed-down) where the veteran can walk with a modified gait but has no ankle motion whatsoever.
How to Describe Your Symptoms
Pain Description
How to describe:
Describe the location (front of ankle, back of heel, along the joint line), character (sharp, aching, burning, throbbing), severity (use 0-10 numeric scale), frequency (constant vs. intermittent), and what makes it worse (standing, walking, cold weather, activity). Distinguish between your average pain level, your best days, and your worst days. The examiner needs to understand your WORST day presentation, not your best.
Worst-day example:
“On my worst days - which happen about 3 times per week - my ankle pain is a 9 out of 10 from the moment I wake up. The joint feels like a grinding, locked vice. I cannot stand for more than 5 minutes without needing to sit down. I have to take prescription pain medication and use my cane even to walk to the bathroom. I cannot drive, cannot climb stairs, and I spend most of the day elevating my leg.”
What the examiner listens for:
Consistency between reported symptoms and observed functional limitations; whether pain is constant or episodic; impact on sleep, daily activities, and employment; use of pain medications and assistive devices.
Understatements to avoid:
Do not say 'my pain is manageable' or 'I take ibuprofen and it helps.' This minimizes the severity. Instead, describe what your pain prevents you from doing even on medication. Do not describe only your average day - include your worst days.
Gait and Mobility
How to describe:
Describe exactly how far you can walk before needing to stop, how long you can stand, whether you limp, and what surfaces you cannot navigate (uneven ground, stairs, grass). Mention your gait pattern changes and whether you use assistive devices. Be specific about distances and time.
Worst-day example:
“I can walk approximately half a block before the pain becomes unbearable and I must stop and rest for 5-10 minutes. I cannot walk on grass or gravel without risking a fall. On bad days, I use my cane for anything beyond moving around my home. I have fallen twice in the past year because my ankle gave way on an uneven surface.”
What the examiner listens for:
Specific functional distances and time limits; history of falls; use of assistive devices (brace, cane, crutches, wheelchair); whether limitations are consistent with the objective findings; gait observation findings.
Understatements to avoid:
Do not say 'I can walk okay' or underestimate distances. If you push through pain to walk further, say so and describe the consequences (worsened pain afterward, needing to rest for hours). Do not downplay assistive device use.
Functional Loss from Ankylosis
How to describe:
The ankle is completely fused - describe everything you cannot do because the joint does not move. Include: cannot push off when walking (no plantar flexion), cannot absorb shock going downhill (no dorsiflexion), cannot pivot or turn quickly, cannot squat fully, cannot climb stairs normally, cannot run or jog, cannot stand on tiptoes.
Worst-day example:
“Because my ankle is completely fused, I cannot push off the ground normally when I walk - I have to swing my entire leg out to the side to take a step. I cannot go down stairs without holding the rail with both hands and going one step at a time. I cannot kneel, squat, or get up from the floor without assistance. My inability to flex my ankle means I cannot exercise, which has caused me to gain weight and develop secondary knee problems.”
What the examiner listens for:
Specific activities limited by the lack of ankle motion; compensatory movements; secondary conditions caused by altered gait; occupational and recreational impact; domestic activity limitations.
Understatements to avoid:
Do not say 'I just work around it.' Describe the compensatory movements you make and their consequences (back pain, knee pain, hip pain, fatigue). The fusion's positional impact on your gait is a key rating factor.
DeLuca Factors: Fatigue, Weakness, Endurance, Incoordination
How to describe:
Per DeLuca v. Brown, you must communicate how your condition worsens with repetitive use. Describe: how your ankle pain or discomfort increases after walking even short distances; how quickly your leg muscles fatigue; whether you experience weakness or giving-way; and whether your coordination is affected. These factors cause functional loss even when the static ROM measurement is the same as the fusion angle.
Worst-day example:
“After walking for more than 10 minutes, my entire affected leg becomes fatigued and I develop a burning sensation throughout my calf. My leg feels weak, like it could give out, and I become unsteady. It takes me 2-3 hours of rest to feel safe walking again. By the end of a day where I was moderately active, I am unable to stand without my cane.”
What the examiner listens for:
Whether the veteran proactively describes worsening with use; specific activities that cause exacerbation; recovery time needed after exertion; safety concerns from weakness or incoordination.
Understatements to avoid:
Do not wait for the examiner to ask about fatigue and weakness - bring it up yourself. Many examiners focus on the ROM measurement without asking about DeLuca factors. Say explicitly: 'I want to make sure we discuss how my condition worsens with activity.'
Flare-Ups
How to describe:
Describe what triggers flare-ups (weather changes, activity, prolonged standing), how often they occur, how long they last, their severity, and what you must do when they occur. Flare-ups represent the worst-case scenario of your condition and are critical to documenting the full picture.
Worst-day example:
“I experience flare-ups approximately once or twice per week, often triggered by cold weather or if I have been on my feet for more than 30 minutes the day before. During a flare-up, my ankle swells, the pain reaches 9 or 10 out of 10, and I am essentially bedridden for 1-2 days. I cannot prepare my own meals or perform any household tasks during these episodes.”
What the examiner listens for:
Frequency, duration, and severity of flare-ups; triggers; impact on daily function during flare-up periods; whether flare-ups cause the condition to be worse than the static snapshot seen on exam day.
Understatements to avoid:
Do not minimize flare-ups because 'they pass eventually.' The frequency and severity of flares are documented on the DBQ and factored into the overall disability picture. If the exam happens to be on a good day, explicitly tell the examiner: 'Today is not a typical day for me - my symptoms are usually worse than what I am showing you right now.'
Deformity and Position of Fusion
How to describe:
Be specific about the fixed position of your ankle. If your foot turns inward, outward, or is severely angled down or up, describe how this affects your walking, footwear, and daily life. If you have had surgery to fuse the ankle, describe the position of fusion as told to you by your surgeon.
Worst-day example:
“My foot is fused turned slightly inward and pointed downward. When I try to walk, my foot does not land flat - it rolls on the outside edge. I have had three ankle sprains on that side because of this positioning. I cannot wear standard shoes and must use custom-molded orthotics. The inward turn has caused my knee to compensate, and I now have chronic knee pain on the same side.”
What the examiner listens for:
Specific deformity type (inversion, eversion, adduction, abduction); impact on weight distribution and gait; secondary musculoskeletal effects; custom footwear or orthotic requirements.
Understatements to avoid:
Do not say 'my foot just looks a little off.' Any deformity - even mild - is critical under DC 5270 because ANY deformity (abduction, adduction, inversion, or eversion) triggers the 40% rating. Ask the examiner directly: 'Did you assess for and document any deformity of the foot position?'
Common Mistakes to Avoid
Describing only your best or average days instead of your worst days
The VA rates your condition based on its full impact, including your worst presentations. Examiners are required to rate based on the picture of average disability - and worst days are part of that picture. Minimizing your symptoms results in an artificially low rating.
Instead: Explicitly state: 'I want to describe my worst days because they are frequent and affect my life significantly.' Describe the 2-3 worst days per week or month in specific, concrete terms. Tell the examiner if today is an unusually good day.
Impact: All levels - can mean the difference between 20%, 30%, and 40%
Failing to mention or demonstrate any rotational deformity (inversion, eversion, adduction, abduction) of the ankylosed ankle
Under DC 5270, ANY deformity of the fused ankle automatically qualifies for the 40% rating - regardless of plantar or dorsiflexion angle. If the examiner does not assess for and document deformity, a veteran with a 40% condition may be rated at only 20% or 30%.
Instead: Before the exam, review your imaging and surgical reports for any mention of deformity. During the exam, ask the examiner: 'I would like you to specifically assess and document whether my ankle has any inversion, eversion, adduction, or abduction deformity.' Point out any visible turning of your foot.
Impact: Critical - determines 20%/30% vs. 40%
Not reporting DeLuca factors (pain, fatigue, weakness, incoordination) because the examiner did not ask
Examiners are required by law to assess DeLuca factors, but many do not proactively ask. If you do not volunteer this information, it may not be documented, and your rating will only reflect the static position of ankylosis rather than the full functional impact.
Instead: Proactively state: 'I also want to discuss how my ankle worsens with activity - I experience significantly increased pain, fatigue, and weakness after even brief walking. I want these DeLuca factors documented.' Use those exact words if necessary.
Impact: All levels - critical for functional loss documentation
Understating the impact on gait, locomotion, and daily activities
The DBQ specifically asks about disturbance of locomotion and interference with standing and sitting. If you say 'I get around okay,' the examiner may document minimal functional impact, which does not reflect the true disability.
Instead: Describe specific, concrete limitations: exact walking distances, time you can stand, activities you have stopped doing, modifications to your home or vehicle, and how your gait pattern has changed and caused secondary problems.
Impact: All levels
Not bringing imaging, surgical reports, or prior medical records to the exam
The examiner documents imaging results on the DBQ. An X-ray confirming bony fusion, the angle of fusion, and any deformity is objective evidence that directly supports the rating criteria. Without imaging, the rating may be based on physical exam alone, which can underrepresent the severity.
Instead: Bring copies of all relevant imaging (X-rays, CT scans, MRI) and radiology reports, surgical operative reports showing the ankle fusion procedure and documented fusion angle, and prior VA or private medical records describing the ankylosis.
Impact: All levels - imaging supports the specific angle and deformity findings
Failing to disclose use of assistive devices or special footwear
The DBQ has specific fields for assistive devices (cane, brace, crutches, walker, wheelchair) and the need for special footwear or orthotics. Use of these devices is objective evidence of functional loss severity and is required for accurate documentation.
Instead: Bring your assistive devices to the exam. Tell the examiner: 'I use a cane on most days and an ankle brace constantly. I also wear custom orthotics because of my foot deformity.' If you use any of these, bring them and demonstrate their use.
Impact: All levels - supports functional loss and disturbance of locomotion
Failing to describe secondary conditions caused by the ankle ankylosis
Ankle ankylosis alters gait mechanics, which causes secondary problems in the knee, hip, and lumbar spine. These may be ratable as secondary conditions if the ankle ankylosis caused or aggravated them. If not mentioned, these conditions will not be evaluated for service connection.
Instead: Tell the examiner: 'Since my ankle fused, I have developed chronic knee pain and lower back pain on the same side from the altered gait. I believe these are secondary conditions caused by my ankle ankylosis.' Ask whether secondary conditions should be separately claimed.
Impact: Relevant to overall combined rating - secondary conditions are separately ratable

Related Conditions
- Ankle, Limited Motion of Alternative rating code when the ankle is not fully ankylosed but has significant limitation of motion. DC 5271 may apply if motion is restricted but not completely absent. M21 1 guidance notes that DC 5271 addresses overall ankle disability and may also be used for instability.
- Subtalar or Tarsal Ankylosis Ankylosis of the subtalar or tarsal joints may occur simultaneously with or independently from tibiotalar ankle ankylosis. These are separately ratable under their own diagnostic codes and should be claimed in addition to DC 5270 if present.
- Arthritis, Post-Traumatic (Ankle) Post traumatic arthritis is a common underlying cause of ankle ankylosis or severe limitation of motion. It may be the basis for the original service connection or a related condition rated under DC 5010 with appropriate analogous codes.
- Knee Condition (Secondary) Altered gait mechanics due to ankle ankylosis frequently cause secondary knee arthritis or pain on the ipsilateral (same side) or contralateral (opposite side) knee. This may be ratable as a secondary condition if the ankle ankylosis caused or aggravated the knee condition.
- Lumbar Spine Condition (Secondary) Compensatory gait changes from ankle ankylosis can cause or aggravate lumbar spine degeneration and pain. May be filed as a secondary condition to ankle ankylosis if there is a medical nexus.
- Avascular Necrosis of the Talus Avascular necrosis of the talus (astragalus) can be an underlying cause of or accompany ankle ankylosis. Separately ratable if diagnosed and service connected.
- Ankle Joint Replacement (Total) Total ankle joint replacement is a related surgical intervention that may precede or follow ankylosis. Post replacement residuals are evaluated under their own criteria and may be rated separately from or in lieu of DC 5270 depending on clinical findings.
- Heterotopic Ossification Heterotopic ossification (abnormal bone formation in soft tissue) can be an underlying mechanism contributing to ankle ankylosis, particularly following traumatic injury or surgery. Documented on the ankle DBQ as a separate finding.
