Osteochondritis Dissecans (OCD) of the Elbow

Elbow pain, locking, and catching in a teenage athlete? OCD of the elbow is a condition where a piece of cartilage and underlying bone separates from the joint surface — most commonly in young throwing athletes and gymnasts. Early diagnosis is critical.

What Is OCD of the Elbow?

Osteochondritis dissecans (OCD) is a condition in which a segment of cartilage and the underlying bone loses its blood supply, becomes unstable, and may eventually separate as a loose body within the joint. In the elbow, OCD occurs most commonly on the capitellum — the rounded end of the humerus that forms the outer part of the elbow joint.

OCD of the elbow predominantly affects skeletally immature athletes aged 10–18, particularly baseball and softball pitchers, gymnasts, and overhead athletes. The repetitive compressive and shear forces across the radiocapitellar joint during overhead activity are the primary cause.

Symptoms

  • Lateral (outer) elbow pain with activity — distinguished from tennis elbow by the younger age group
  • Stiffness and loss of full elbow extension
  • Swelling in the elbow joint
  • Locking or catching — if a fragment has separated and become a loose body
  • Decreased throwing performance or pain with overhead activity
OCD vs. Little League ElbowBoth OCD and Little League Elbow cause lateral elbow pain in young athletes, but they are distinct conditions. Little League Elbow involves the medial epicondyle growth plate (inner elbow). OCD involves the capitellum cartilage (outer elbow). OCD is generally considered more serious because cartilage has limited healing capacity.

Diagnosis

X-rays can show OCD lesions as flattening or irregularity of the capitellum. MRI is the gold standard, defining lesion size, stability (is the fragment attached or loose?), and whether joint fluid is tracking underneath the fragment. MRI findings directly guide treatment decisions.

Treatment

Conservative — Stable Lesions

Stable OCD lesions (fragment firmly attached, no joint fluid undermining) in skeletally immature athletes are treated with complete rest from throwing and overhead activity for 3–6 months, followed by gradual return. The open growth plate in younger athletes provides healing potential that is not present after skeletal maturity.

Surgical — Unstable or Failed Conservative

  • Arthroscopic debridement: Removal of unstable cartilage and loose bodies, drilling the OCD crater to stimulate healing
  • Fragment fixation: If the fragment is large and viable, reattachment with small screws or pins
  • Osteochondral grafting: For large lesions, filling the defect with a cartilage plug from another area
Can a young athlete return to pitching after OCD? +
Yes — with appropriate treatment. Athletes with stable lesions treated conservatively typically return to full throwing in 3–6 months. Athletes who require surgery typically return to competitive throwing in 6–12 months. The prognosis is generally better in younger athletes with open growth plates. Returning too early significantly increases the risk of lesion progression.
Is OCD of the elbow the same as OCD of the knee? +
The same condition (osteochondritis dissecans) occurs in both joints, but the elbow is more challenging because: (1) elbow cartilage has less healing capacity, (2) the capitellum has a more limited blood supply, and (3) elbow range of motion is critically important for daily function and sport. OCD of the elbow tends to require closer monitoring and has a less predictable natural history than knee OCD.
