[3 adolescents with hip pain caused by idiopathic chondrolysis]

The cases are described of three adolescents in whom hip pain was found to be due to chondrolysis. Arthroscopy revealed chronic synovitis in all three cases. It is stated that the synovitis is probably the cause of the articular damage and that the disorder should be regarded as juvenile chronic arthritis of the oligoarticular type. Treatment with intra-articular triamcinolone acetonide and in two patients with an anti-inflammatory agent as well resulted in almost complete recovery of hip function.
