Limitation of Knee Flexion & Other Orthopedic Issues Veterans Experience
Legally Reviewed by: Josh Conklin
Your knee never came back right after service, and now your hip aches too, your back throbs after long days, and the ankle you favor to protect that knee is starting to give out on its own.
A single number on a rating decision often can’t capture all of that. VA rules score limitation of knee flexion in exact degrees. However, the pain, swelling, and other joints strained protecting a bad knee may not show up on a good day in a quiet exam room.
Capovilla & Williams built its practice around exactly these types of patterns, connecting a knee injury to everything it dragged down with it. Tell a veterans disability benefits attorney what your knee and the joints around it stop you from doing, and they’ll tell you plainly whether your rating fits.
Key Takeaways
- Limitation of knee flexion is rated under 38 C.F.R. § 4.71a, Diagnostic Code 5260, while limited extension is rated separately under Diagnostic Code 5261.
- A knee that only locks up during flare-ups still counts, since examiners are required to weigh pain and weakness alongside a single range of motion reading.
- Hip, back, ankle, and opposite knee problems caused by favoring a bad knee can earn their own secondary rating.
- A rating that has sat untouched for years while a knee got worse is a reason to file for an increase, not a reason to accept it.
- Buddy statements and independent medical opinions often catch what a single VA exam misses.

How the VA Scores Your Knee Flexion
The VA rates limitation of knee flexion under 38 C.F.R. § 4.71a, Diagnostic Code 5260. A normal knee bends to about 140 degrees. Flexion limited to:
- 60 degrees can be rated at 0%
- 45 degrees earns 10%
- 30 degrees earns 20%
- 15 degrees earns 30%
Limitation of extension works the opposite way and is rated separately under 38 C.F.R. § 4.71a, Diagnostic Code 5261. A knee that will not straighten past 10 degrees is rated 10%. Past 15 degrees is 20%, and past 20 degrees is 30%, climbing higher from there.
So why does a veteran with real, daily knee pain still walk away with a 0% or 10% rating? Because a single exam often measures your knee on a good day, in a quiet room, without the pain and swelling you deal with after a full shift on your feet. VA rules require examiners to weigh pain, weakness, and flare-ups, not just the number on the goniometer (the tool used to measure joint motion). That is where many under-rated knee claims go wrong.
This reflects VA rating criteria under 38 C.F.R. § 4.71a as of July 2026.
When One Bad Knee Becomes Three Bad Joints
A limited knee rarely stays contained to the knee. Veterans favor the good leg for years, and the hip, back, and opposite knee absorb the strain instead.
Hip, Back, and Opposite Knee Strain
Some veterans develop early arthritis in the knee they’ve leaned on for a decade. Others develop chronic lower back pain from an uneven walk that never got looked at. The VA calls this a secondary service connection, and a doctor’s opinion linking the new condition to the original knee can mean an added rating on top of it.
Ankle and Foot Problems
Plantar fasciitis and heel pain show up often in the foot a veteran leans on to protect a bad knee, and none of it appears on an exam built to measure one joint. To catch it, a medical opinion has to look at the whole lower body, not just the joint named on the claim form.
Why Two Exams Can Produce Two Different Ratings
Many veterans get an initial rating right after leaving the service and never look at it again. For example, a veteran may carry a 10% knee rating for years while flexion dropped from 45 degrees to 25, unrated the entire time. That gap between the file and the joint is where real compensation gets left on the table, year after year.
How We Build a Knee Flexion Appeal That Holds Up
Building a knee flexion appeal that holds up follows a clear sequence. Not all of these steps are required in every case, but we may:
- Pull the full service and VA medical file, including every prior Compensation & Pension (C&P) exam.
- Bring in an independent medical examiner when the file needs an opinion built around flare-ups and functional loss, not one reading.
- Collect statements from spouses, fellow service members, and coworkers who saw the limp, the missed workouts, and the stairs skipped.
Our team can walk through your specific exam results and flag what’s missing before you file anything else.
When to File for an Increased Rating
If a knee or the joints around it have gotten worse since the last decision, VA rules allow a veteran to file an increased rating claim rather than live with an old number. Veterans generally have one year from a decision date to file a Notice of Disagreement, Higher-Level Review, or Supplemental Claim and keep the original effective date. If you file later, the claim can still succeed, but the new effective date usually starts on the filing date, not the date the knee actually failed.

Frequently Asked Questions
Can I get separate ratings for limited flexion and limited extension in the same knee?
Yes, VA guidance lets you receive both under Diagnostic Codes 5260 and 5261 in the same knee, as long as you don’t count the same symptom twice. Many veterans never realize this and leave a second rating on the table. Ask to have your file checked for both numbers, not just one.
What if my knee only locks up during flare-ups or after activity?
It still counts. VA rules require examiners to weigh pain, weakness, and flare-ups, not just what your knee does in the exam room. Write down your worst days before the exam, because your own description carries real weight.
Can I get a separate rating for knee instability?
Yes. Recurrent instability or subluxation is rated separately under Diagnostic Code 5257, apart from the flexion and extension codes above. This covers a knee that buckles, shifts, or gives way during normal movement, not one that won’t bend or straighten fully. Some veterans qualify for this rating in addition to a flexion or extension rating.
Do I need surgery to qualify for a knee flexion rating?
No, the VA rates limitation of motion whether or not surgery ever happened. Plenty of veterans with arthritis, old ligament tears, or chronic swelling qualify without going under the knife. If your knee still limits you, surgery status shouldn’t be the deciding factor.
How long do I have to appeal a low knee rating?
You’ve got one year from the date of your decision to file a Notice of Disagreement or Higher-Level Review, and the same window applies to a Supplemental Claim if you want to keep your original effective date. If you miss that window, you can still file, but you’ll likely lose months of back pay. Mark the date now and don’t wait on it.
What should I expect at my Compensation and Pension exam for my knee?
The examiner will measure how far your knee bends and straightens with a tool called a goniometer, then ask about pain, swelling, and flare-ups. Be specific about your worst days, not just how your knee feels that morning, since the exam is required to account for both.
What does it cost to hire an attorney for a knee rating appeal?
Nothing out of pocket. Fees come only as a percentage of the benefits recovered, and if nothing gets recovered, you owe nothing. That means the only real cost of asking is the time it takes to make the call.
Capovilla & Williams: Your VA Disability Law Firm
If a knee flexion rating doesn’t match daily reality, or another joint has gotten worse since the last decision, now is the time to find out where things stand. Our team pulls the full file first, because a rating built on one exam rarely tells the whole story. A stronger record may turn a 10% knee rating into a 30% one without a single new symptom, just better proof of the same knee.
We live by Vincit Qui Patitur, “he who endures wins,” and a knee flexion appeal takes endurance too. Contact our firm today, tell us what your knee costs you now, and let’s find out whether your number still fits.
