Dislocated Semilunar Cartilage (Knee Meniscus) — VA Diagnostic Code 5258

Understanding how the VA rates a dislocated semilunar cartilage with locking, pain, and joint effusion.

What This Condition Is

The semilunar cartilage refers to the meniscus in the knee — the crescent-shaped cartilage that cushions the joint. Under Diagnostic Code 5258, the VA addresses a dislocated semilunar cartilage that causes frequent episodes of "locking," pain, and effusion (fluid buildup) into the joint.

This condition falls under the Musculoskeletal System and is evaluated under 38 CFR § 4.71a.

Available Rating Level

Under Diagnostic Code 5258, there is a single disability rating available:

What the VA Looks For

When evaluating a claim under this code, the VA considers whether the semilunar cartilage is dislocated and whether it is accompanied by the following symptoms:

  • Frequent episodes of "locking" in the knee joint
  • Pain
  • Effusion (fluid accumulation) into the joint

The presence of these features together is what the 20% evaluation describes.

How to claim this

Knowing the criteria is the first half. Getting your file to show them is the second.

  1. Find your level in the stack

    Read each rung against what your medical records already say. The level your records document today is the one the VA can support today.

  2. Name the gap

    Look at the rung above yours and write down exactly what it asks for that your file does not show yet — a diagnosis, a measurement, a prescribed brace, a doctor’s opinion linking it to service.

  3. Claim it by code

    File under diagnostic code 5258 and attach the evidence for the level you are asking for. Other Musculoskeletal System codes may cover your secondary conditions.
