Knee Limitation of Flexion — VA Disability Rating Criteria (DC 5260)

Diagnostic Code 5260 · 38 CFR §4.71a

What Is It?

Limitation of flexion means a reduced ability to bend the knee. VA measures it in degrees from a straight leg, and Plate II in 38 CFR 4.71 sets normal knee motion at 0 degrees of extension to 140 degrees of flexion. DC 5260 assigns a percentage based on how far short of normal the bend stops. The number that surprises most veterans is where the schedule starts paying: flexion has to be limited to 45 degrees before a single percent is assigned, and 60 degrees of flexion is expressly a 0 percent evaluation. Sixty degrees is roughly the point where you can no longer sit comfortably in a car seat, so a knee that hurts constantly and swells after a shift can still measure well outside compensable range. That is why the majority of knees that end up rated 10 percent get there through 38 CFR 4.59 and DC 5003 rather than through the flexion table itself. Section 4.59 states the intent to recognize actually painful, unstable, or malaligned joints as entitled to at least the minimum compensable rating for the joint, and DC 5003 provides 10 percent for a joint with arthritis whose limitation of motion is noncompensable. The other structural point worth knowing is that one knee can carry several ratings at once. Flexion, extension, instability, arthritis, and meniscal pathology are separate diagnostic codes measuring different things, and when each is independently supported they combine rather than compete.

Rating Criteria

Evidence Needed

• Goniometer range of motion measurements in degrees, taken on both active and passive motion and in both weight-bearing and non-weight-bearing positions. Section 4.59 requires testing in all of those conditions and, where possible, against the opposite undamaged knee.
• Measurements taken after repetitive use, typically three repetitions. If the knee measurably loses motion after repetitions, that lower figure is the one that should drive the evaluation.
• X-rays establishing degenerative arthritis. This is what unlocks the DC 5003 pathway when your flexion is better than 45 degrees but the joint is genuinely painful.
• MRI or operative reports documenting meniscal tears, cartilage loss, or ligament damage, which support separate evaluations under DC 5257, 5258, or 5259.
• Service treatment records tying the knee to a specific in-service injury, or to the cumulative demands of running, rucking, jumping, and load carriage.
• A medical provider's prescription for a brace, cane, crutch, or walker, with the reason stated. Since the 2021 revision of DC 5257 the presence or absence of a prescribed assistive device is written directly into the instability criteria.
• Treatment history: injections, physical therapy, arthroscopy, and any planned or completed replacement.
• Lay statements describing what the knee stops you doing — stairs, ladders, kneeling to work on equipment, standing through a shift.

C&P Exam Tips

• The examiner uses a goniometer and records the point where motion stops. Stop where the pain starts and say so, because under 38 CFR 4.59 the onset of painful motion is the finding that matters, not the maximum you can force.
• The exam should cover active motion, passive motion, weight-bearing, and non-weight-bearing, and should note the opposite knee for comparison. If the report is missing those, it is incomplete under 4.59 and that is a documented basis for asking for a new or corrected examination.
• Expect repetitive-use testing. If the third repetition is worse than the first, make sure the examiner writes the post-repetition number down rather than only the best one.
• Give flare-ups in numbers. "After a day on my feet I cannot bend it past about 60 degrees and it stays that way overnight" is usable. VA is required to consider functional loss during flare-ups even when you are not flaring at the exam.
• Report instability separately and precisely: how often the knee gives way, whether you have fallen, and exactly what device a provider prescribed. The 2021 version of DC 5257 keys its 10, 20, and 30 percent levels to whether a medical provider prescribed a brace, an assistive device, or both.
• Mention locking, catching, and swelling by name. Frequent episodes of locking with pain and effusion into the joint is the specific language of DC 5258.
• If both knees are involved, say so. Two service-connected knees trigger the bilateral factor, which adds a further increment before the ratings are combined.
• Do not tough it out. A single good day at the exam becomes the permanent record of your knee unless the file shows otherwise.

How to File

File on VA Form 21-526EZ and specify the knee — left, right, or both. List each ratable aspect as its own claimed condition rather than filing one generic "knee condition": limitation of flexion, limitation of extension, instability, arthritis, and any meniscal problem. Under VAOPGCPREC 9-2004 flexion and extension of the same knee may be rated separately when each is compensable, and under VAOPGCPREC 23-97 and 9-98 instability under DC 5257 may be rated separately from arthritis with limitation of motion, because they compensate different impairments. Describe the in-service origin concretely — the specific injury, or the years of running, rucking, and jumping — and attach imaging and treatment records. If a provider has prescribed a brace or a cane, include that prescription; it is now written into the DC 5257 criteria. A VSO can check that nothing ratable was left off the form before you submit.

Common Mistakes

• Filing "knee pain" as a single condition. A knee can support ratings under DC 5260, 5261, 5257, 5003, and 5258 at the same time, and VA generally rates what you claimed.
• Assuming a painful knee that bends past 45 degrees is worth nothing. With X-ray arthritis and objectively painful motion, 38 CFR 4.59 and DC 5003 provide the minimum compensable 10 percent for that joint.
• Pushing through pain at the C&P exam to show you are not exaggerating. The measurement taken is the measurement rated.
• Letting an examiner skip passive, weight-bearing, or non-weight-bearing testing. Section 4.59 calls for all of it, and an incomplete range of motion exam is a fixable problem if you raise it.
• Describing instability vaguely. The current DC 5257 turns on whether a medical provider prescribed a brace, an assistive device, or both, so "it feels wobbly" and "my orthopedist prescribed a hinged brace and a cane" land in different rating tiers.
• Forgetting the bilateral factor when both knees are service connected.
• Not claiming what the bad knee did to the rest of the body. Years of limping produce low back and opposite-knee problems that are ratable as secondary conditions.

Frequently Asked Questions

Can I get separate ratings for flexion and extension of the same knee?

Yes. Under VAOPGCPREC 9-2004, VA may assign separate evaluations for limitation of flexion under DC 5260 and limitation of extension under DC 5261 for the same knee when each is compensable on its own. They measure different impairments — how far the knee bends and how far it straightens — so rating both is not pyramiding.

What are normal range of motion values for the knee?

Plate II in 38 CFR 4.71 sets normal knee motion at 0 degrees of extension to 140 degrees of flexion. Under DC 5260 flexion limited to 60 degrees is still 0 percent, so the schedule tolerates a substantial loss of bend before paying anything.

My knee hurts constantly but I can still bend it past 45 degrees. Is it worth anything?

Usually yes, but through a different route. Section 4.59 states the intent to recognize actually painful, unstable, or malaligned joints as entitled to at least the minimum compensable rating for the joint, and DC 5003 assigns 10 percent per major joint where arthritis is established by X-ray and the limitation of motion is noncompensable. That is how most painful service-connected knees reach 10 percent.

Can I get a rating for instability on top of my flexion rating?

Yes, when the evidence supports both. VA General Counsel opinions 23-97 and 9-98 allow a separate evaluation under DC 5257 for recurrent subluxation or lateral instability alongside a rating for arthritis with limitation of motion. Note that DC 5257 was rewritten in 2021 and its levels now depend heavily on whether a medical provider prescribed a brace, an assistive device such as a cane, crutch, or walker, or both.

What are the DeLuca factors?

They come from DeLuca v. Brown and require VA to consider pain on movement, weakness, excess fatigability, incoordination, and additional loss of function during flare-ups and after repetitive use — not just a single measurement taken on one day. The practical effect is that a knee measuring 70 degrees at rest but 45 after a day of work should be rated on the functional reality, provided the record documents it.

How does a knee replacement affect my rating?

DC 5055 covers knee resurfacing or replacement. A total replacement carries 100 percent for four months following implantation, which begins after the one-month total convalescent rating under 38 CFR 4.30 runs out. After that period it is 60 percent for chronic residuals of severe painful motion or weakness, intermediate degrees are rated by analogy to DC 5256, 5261, or 5262, and there is a minimum 30 percent for a total replacement. Resurfacing carries the four-month total but no minimum evaluation afterward.

Does a torn meniscus get its own rating?

It can. DC 5258 provides 20 percent for dislocated semilunar cartilage with frequent episodes of locking, pain, and effusion into the joint, and DC 5259 provides 10 percent for symptomatic removal of semilunar cartilage. Those are separate from limitation of motion, so the specific words locking, catching, and swelling are worth getting into the exam report.

Both my knees are rated. Does that change the math?

Yes. When disabilities affect both lower extremities the bilateral factor applies: VA combines the two ratings, adds 10 percent of that combined figure, and only then combines the result with everything else. It is a small addition, but it is automatic and easy to overlook when checking a rating decision.
