Abstract
1. Sixteen patients with articular cartilage erosions after slight injury have been described, as have the results of their treatment.
2. The clinical features of this rarely diagnosed condition are discussed. Attention is drawn to "articular crepitus" and "synovial crepitus" as useful physical signs in establishing the diagnosis.
3. A radiographic sign of localised subarticular osteoporosis is reported and discussed.
4. The surgical treatment used was either shaving of the affected area of cartilage or a combination of shaving with drilling of the subchondral bone plate.
