Chondrolysis After Hip Arthroscopy

We report the case of a 58-year-old woman who presented with left hip pain and was diagnosed with femoroacetabular impingement. She underwent hip arthroscopy to repair a degenerative labral tear, as well as radiofrequency debridement and microfracture of the exposed chondral defect, and femoral osteoplasty. Two months after hip arthroscopy, hip pain and limping began. Hip radiography showed a concentric decrease of joint space and no signs of joint incongruity or osteophytosis. Revision surgery 4 months after hip arthroscopy showed that the cartilage of the femoral head was soft and separated from the subchondral bone.
