Knee VA Rating: Why Most Veterans Leave Money on the Table
The knee is one of the most under-rated joints at the VA because most veterans do not know they can receive separate ratings for limitation of flexion, limitation of extension, AND instability — on EACH knee. This guide covers every knee diagnostic code and the case law that protects your right to separate ratings.
The Three Separate Knee Ratings
Under VA General Counsel precedent opinions, a single knee can receive up to THREE separate ratings without pyramiding: limitation of flexion (DC 5260), limitation of extension (DC 5261), and instability/subluxation (DC 5257). Most veterans only receive one. Understanding these separate rating pathways is the difference between a 10% knee rating and a 30%+ knee rating — per knee.
VAOPGCPREC 23-97 (instability separate from ROM); VAOPGCPREC 9-04 (flexion separate from extension)Limitation of Flexion (DC 5260)
Normal knee flexion is 0-140 degrees. The VA rates based on where flexion is limited TO (not from).
Limitation of Extension (DC 5261)
Normal extension is 0 degrees (fully straight). Any inability to fully straighten the knee is rated under DC 5261 — separately from flexion under VAOPGCPREC 9-04.
Instability (DC 5257)
Under VAOPGCPREC 23-97, knee instability (recurrent subluxation or lateral instability) is rated SEPARATELY from limitation of motion. This is rated on severity, not ROM: 10% (slight), 20% (moderate), 30% (severe). A veteran can receive a ROM-based rating AND an instability rating simultaneously. This is one of the most commonly missed separate ratings.
38 C.F.R. 4.71a, DC 5257; VAOPGCPREC 23-97Meniscal Conditions (DC 5258-5259)
Dislocated semilunar cartilage (torn meniscus) with frequent episodes of locking, pain, and effusion rates 20% under DC 5258. Removal of semilunar cartilage (meniscectomy) rates 10% under DC 5259. These may be rated in addition to ROM limitations depending on the specific symptoms.
The Bilateral Factor
If both knees are service-connected, the bilateral factor under 38 C.F.R. 4.26 adds approximately 10% to the combined value of both knee ratings before combining with other disabilities. This is automatic but only applies if both extremities are rated.
38 C.F.R. 4.26 (Bilateral Factor)Secondary Conditions
Common secondaries from knee conditions: hip conditions (altered gait), lumbar spine (compensatory movement), ankle conditions, radiculopathy (if gait changes affect nerve compression), depression/anxiety (chronic pain, mobility loss). Each secondary is rated under its own DC and combined using VA math.
