Knee DBQ Field Guide

The Knee DBQ is unusual in the schedule: one knee can carry up to three separately compensable ratings at the same time. Limited flexion (DC 5260), limited extension (DC 5261), and recurrent subluxation or lateral instability (DC 5257) each get their own rating — they do not pyramid (overlap), they stack under 38 CFR § 4.25. Plus meniscal codes (5258 / 5259), genu recurvatum (5263), the § 4.59 painful motion floor, and the Correia/DeLuca measurement rules that apply to all musculoskeletal exams.

That makes the knee one of the highest-leverage musculoskeletal claims to understand — and one of the most-under-rated when the examiner only addresses one of the three codes.

What the examiner is filling out

The DBQ (Knee and Lower Leg Conditions Disability Benefits Questionnaire) covers:

Diagnosis — specific knee condition(s). Each gets its own DC.
Range-of-motion measurements — flexion (normal 0–140°), extension (normal 0°, hyperextension or loss of full extension noted). Goniometer measurements.
Joint stability tests — anterior / posterior / medial-lateral. Examiner marks 1+ / 2+ / 3+ laxity.
Meniscal symptoms — locking, frequent effusion, pain.
Functional loss — § 4.59 painful motion, § 4.40 functional loss, § 4.45 additional factors (less movement, more movement, weakened movement, excess fatigability, incoordination, pain on use, swelling, deformity, atrophy, instability of station, disturbance of locomotion, interference with sitting/standing).
Flare-up estimation (DeLuca / Mitchell) — ROM during flare-ups, after repetitive use, weight-bearing vs non-weight-bearing.
Imaging / surgical history — X-ray, MRI, prior arthroscopy or replacement.

DC 5260 — Limitation of flexion

0%Flexion limited to 60°

Painful motion gets §4.59 minimum compensable 10% even when flexion is full — see below.

10%Flexion limited to 45°

Most common starting tier with meaningful limitation.

20%Flexion limited to 30°

30%Flexion limited to 15°

Maximum for limitation of flexion alone.

DC 5261 — Limitation of extension

0%Extension limited to 5°

10%Extension limited to 10°

20%Extension limited to 15°

30%Extension limited to 20°

40%Extension limited to 30°

50%Extension limited to 45°

DC 5257 — Recurrent subluxation or lateral instability

10%Slight

Occasional giving-way, examiner finds 1+ laxity on stability test.

20%Moderate

Frequent giving-way, brace use, 2+ laxity.

30%Severe

Constant giving-way, falls, locked-knee episodes, 3+ laxity, often surgical candidate.

The under-rated stacking move: DC 5260 + DC 5261 + DC 5257 are three separate ratings on the same knee, and they all combine under § 4.25. A veteran with painful flexion (10% under 5260) + painful extension (10% under 5261) + moderate instability (20% under 5257) gets all three ratings, not just one. After § 4.25 math, that is about a 36% combined for a single knee. The examiner is required to address all three categories; the rater is required to apply them. If your decision letter only addresses one DC, that is a Supplemental Claim issue.

§ 4.59 painful motion — the 10% floor

38 CFR § 4.59 says “actually painful, unstable, or malaligned joints, due to healed injury, are entitled to at least the minimum compensable rating for the joint.” For the knee, that minimum is 10%. Even if your flexion is full and your extension is full, if motion is painful, you should get 10% — not 0%. The examiner is required to test for pain on motion and report it.

The Federal Circuit decisions Burton v. Shinseki (Vet. App. 2011) and Petitti v. McDonald (Vet. App. 2017) reinforced that § 4.59 applies broadly — painful motion warrants the minimum compensable rating regardless of whether the motion is measurably limited.

Meniscus codes — DC 5258 and 5259

20%DC 5258 — Dislocated semilunar cartilage with frequent episodes of locking, pain, and effusion into the joint

One rating tier — flat 20%. Requires documentation of locking episodes, pain, and effusion (swelling). Often documented post-arthroscopy or on MRI.

10%DC 5259 — Symptomatic removal of semilunar cartilage

Flat 10% after meniscus removal (meniscectomy). Records of the procedure plus ongoing symptoms suffice.

DC 5258 is not ratable concurrently with DC 5259 on the same knee. But either can be rated alongside DC 5260, 5261, and 5257 (pyramiding analysis from VA OGC Prec. 9-2004 and rater practice).

The phrases that secure each DC

Magic words for this tier

For DC 5260 / 5261 (flexion / extension):

“I can’t fully bend my knee.”
“I can’t fully straighten my knee — it stays slightly bent.”
“Bending hurts, and the pain stops me at [degrees].”
“During a flare-up, I can’t bend it more than [degrees].” (Triggers the DeLuca / Mitchell flare-up estimation.)

Magic words for this tier

For DC 5257 (instability):

“My knee gives way when I walk on uneven ground / descend stairs.”
“I wear a brace [most days / for activity / all the time].”
“I have fallen / nearly fallen [N] times in the past [period].”
“My knee locks up sometimes — I have to manipulate it to release.” (Also relevant to DC 5258.)

Magic words for this tier

For § 4.59 painful motion floor:

“Bending is painful even when I can complete the range.”
“The pain starts at [degrees] of flexion / extension.”
“After repetitive use the pain worsens and ROM decreases.”

The goniometer + Correia rule

Same as the spine: range-of-motion must be measured with a goniometer, and the exam must include active + passive ROM, weight-bearing + non-weight-bearing, and a comparison to the opposite (undamaged) joint. Without those measurements, the exam is inadequate under Correia v. McDonald (Vet. App. 2016). If your C&P examiner did not use a goniometer or did not test the opposite knee, you have grounds for a Supplemental Claim requesting a new exam.

What NOT to say

“The knee is fine when I’m sitting.” (Not the bar — the question is motion and use.)
“I just take ibuprofen and push through.” (Suggests no functional impairment.)
“It only gives out occasionally.” (For DC 5257, the levels are slight / moderate / severe by frequency — quantify frequency.)
“Bending all the way is fine.” (Without specifying pain or fatigue at full range, this cuts the § 4.59 floor.)
“I don’t need the brace much.” (Brace dependence is decisive for DC 5257 tiering — be specific about when and why you wear it.)

Knee replacement and post-operative ratings

If you have had a total knee replacement (TKR / arthroplasty), DC 5055 applies:

100% for the 4-month post-operative period (per current § 4.71a)
60% with chronic residuals consisting of severe painful motion or weakness in the affected extremity
30% minimum after the 100% period ends, even with no other symptoms

See the knee replacement condition guide for the full schedule. The 4-month figure is correct — some online resources still cite the old 13-month period that was changed in the 2024 musculoskeletal restructure.
