Osteochondritis dissecans of the lateral humeral condyle in a table tennis player.

The case of a table tennis player suffering from intra-articular loose bodies of the elbow is reported. The patient developed the first signs of osteochondritis dissecans of the right lateral humeral condyle at age 16 but underwent surgery only 6 yr later. He has now resumed training and competition, despite some residual stiffness due to early osteoarthritis. This is the first case of osteochondritis dissecans of the elbow ascribed to this sport. It was probably due to repetitive valgus compressive stresses at the radiocapitellar joint during the forced movements imposed by high-level table tennis in a young athlete.
