Knee Meniscal Conditions

1. What This Condition Is

The menisci are two C-shaped cartilage structures in the knee — the medial meniscus on the inner side and the lateral meniscus on the outer side — that act as shock absorbers, distribute load, and stabilize the joint. When a meniscus tears or is surgically removed, the knee loses structural support and the ability to distribute force evenly across the joint surface. Veterans develop meniscal injuries from direct trauma (pivoting, impact, twisting under load), repetitive stress from sustained physical demands, and the wear of years of service on hard surfaces in boots under load.

Knee meniscal conditions are rated under distinct diagnostic codes from the limitation-of-flexion code (DC 5260), the limitation-of-extension code (DC 5261), and the instability code (DC 5257). Many veterans with knee injuries have all three conditions — limited flexion, limited extension, and instability or meniscal pathology — but file only under one code. Each separately ratable condition reflects distinct functional loss and can be rated simultaneously without pyramiding.

The two meniscal diagnostic codes cover different anatomical situations: DC 5258 applies when meniscal tissue remains in the joint and is causing symptoms (torn or damaged meniscus), and DC 5259 applies when the meniscus has been surgically removed (meniscectomy, either partial or total). The ratings under these two codes differ, and knowing which code applies to your situation is essential to filing correctly.

2. VA Rating Criteria

Meniscal conditions are rated under 38 CFR § 4.71a.

DC 5258 — Cartilage, Semilunar, Dislocated, With Frequent Episodes of "Locking," Pain, and Effusion

DC 5258 requires three elements: locking of the joint (the knee catching or getting stuck in a position), pain, and effusion (fluid accumulation in the joint). "Frequent episodes" means this pattern occurs recurrently, not as a single incident. This code does not have multiple rating tiers — it is rated at 20% when the criteria are met.

DC 5259 — Cartilage, Semilunar, Removal of, Symptomatic

DC 5259 applies when the meniscus has been partially or totally removed — typically through arthroscopic surgery. "Symptomatic" means the veteran continues to have symptoms (pain, swelling, instability, or limitation) after the surgery. This code rates at 10% when the post-surgical state is symptomatic.

Combining Meniscal Ratings with Other Knee Codes

A veteran who has had a meniscectomy under DC 5259 and also has limitation of flexion under DC 5260 or limitation of extension under DC 5261 may receive ratings under multiple codes simultaneously if each code reflects a distinct functional loss. The combined disabilities formula under 38 CFR 4.25 applies.

Under DeLuca v. Brown, 8 Vet. App. 202 (1995), the VA must consider functional loss due to pain, weakness, and fatigability beyond what range-of-motion measurements show. If the meniscal condition causes pain-limited motion or post-exercise swelling and limited motion, that functional loss must be documented and factored into any related range-of-motion ratings.

3. What to Expect at Your C&P Exam

The examiner will assess your knee using orthopedic provocative tests. For meniscal conditions, expect the McMurray test (joint line pain and clicking with knee rotation), the Thessaly test (weight-bearing rotation test), and Apley's compression test. The examiner will check for joint line tenderness, effusion (palpable fluid in the joint), crepitus (grinding or clicking with motion), and locking episodes.

For DC 5258, you must describe the locking episodes specifically: how often they occur, what triggers them, how long the knee stays locked, and whether the knee must be manipulated to release. You must also describe the associated pain and any episodes of joint swelling. If you have these three elements occurring together and repeatedly, that is the criterion for the 20% rating.

For DC 5259 (post-meniscectomy), describe your current symptoms. The surgery having occurred does not eliminate your claim — the question is whether you remain symptomatic afterward. Describe persistent pain, swelling, instability, or functional limitation that continues after surgery.

In either case, also describe how your meniscal condition affects your daily function: difficulty walking on uneven ground, inability to kneel, difficulty climbing stairs, and activities you avoid because of your knee.

4. Evidence You Need to Win

Diagnosis: MRI reports documenting the meniscal tear (for DC 5258 claims) or operative reports documenting meniscectomy (for DC 5259 claims). Arthroscopy operative reports are the gold-standard evidence for meniscectomy. The report should identify which meniscus was involved (medial or lateral) and the extent of the procedure (partial versus total meniscectomy).

Nexus Letter: A private orthopedic surgeon, sports medicine physician, or physiatrist must connect the meniscal injury or meniscectomy to military service. The letter must identify the in-service event or cumulative physical demands that caused the meniscal pathology, describe the current findings, and state "at least as likely as not" that service caused or contributed to the condition. The letter must meet Barr v. Nicholson adequacy standards.

DBQ Form: VA Form 21-0960M-9 (Knee and Lower Leg Conditions DBQ). Request that your treating orthopedic surgeon complete this form with current findings, including locking episodes (frequency, pain, effusion) for DC 5258 claims or symptomatic post-surgical status for DC 5259 claims.

Locking Episode Documentation: For DC 5258, medical records documenting episodes of joint locking, effusion, and pain are critical. Emergency room visits, urgent care appointments, or orthopedic visit notes during acute episodes corroborate the "frequent episodes" requirement.

Personal Statement: Describe locking episodes in detail (for DC 5258): how often they occur, what you were doing when they happened, and how they affect your ability to walk, work, or perform daily activities. For DC 5259, describe the ongoing symptoms since surgery.

Buddy Statements (VA Form 21-10210): Witnesses who have seen your knee lock up, observed your swelling after activity, or witnessed you during an acute episode provide useful lay corroboration.

5. Secondary Conditions to Consider

Degenerative Arthritis: Meniscal damage or removal accelerates degenerative changes in the articular cartilage of the knee. Secondary degenerative arthritis under DC 5003 is ratable if confirmed by X-ray showing joint space narrowing or osteophyte formation.

Limitation of Flexion (DC 5260) and Extension (DC 5261): Post-meniscectomy pain and swelling may cause functional limitation of knee motion. If the veteran also has limitation of flexion and extension not captured by the meniscal code, those separate ratings apply simultaneously.

Patellofemoral Syndrome: Altered knee mechanics following meniscal injury or removal can produce secondary patellofemoral pain syndrome. This may be ratable separately if it represents distinct functional loss.

Knee Instability (DC 5257): Meniscal conditions that destabilize the joint can produce concurrent lateral instability ratable under DC 5257. If the veteran has both meniscal pathology and instability, both should be claimed.

Hip and Lower Back: Altered gait mechanics from a painful or unstable knee increase stress on the ipsilateral hip and lumbar spine. Secondary conditions in these regions are ratable under 38 CFR 3.310 with an appropriate nexus.

Depression and Anxiety: Chronic knee pain and functional limitation contribute to secondary mood disorders, particularly when the condition prevents recreational activities the veteran relied upon.

6. Common Mistakes That Kill Claims

Not filing under the meniscal code at all. Veterans with documented meniscal tears or meniscectomies frequently receive ratings only under DC 5260 (flexion) or DC 5261 (extension) and never file under DC 5258 or DC 5259. These are separate conditions with separate ratings. Review your knee documentation and file under all applicable codes.

Not describing locking episodes for DC 5258. The rating formula under DC 5258 requires locking, pain, and effusion. A veteran who describes only knee pain without mentioning the locking and swelling components does not meet the criteria. Be specific about all three elements.

Assuming meniscectomy eliminates the claim. Surgery does not remove the service-connected basis for a claim — it creates the basis for DC 5259. A veteran who had a meniscectomy during or after service and continues to have symptoms is entitled to at least 10% under DC 5259 for symptomatic post-surgical status.

Not documenting the full picture of knee disabilities. Veterans often have simultaneous meniscal pathology, flexion limitation, extension limitation, and instability on the same knee. Each is separately ratable. Filing only one claim significantly undervalues the total disability from a complex knee injury.

Presenting on a good day. If your knee is symptomatic on most days but you happen to be having a better day at the C&P exam, the examiner's findings will reflect your best-day function. Describe your worst-day and average-day range. If the examiner tests you and you have no effusion that day, note how frequently effusion occurs and bring records documenting prior episodes.
