OBJECTIVE: To study clinical results of reduction and fixation under arthroscopy for the treatment of @entity75 in the knee. METHODS: From December 2012 to December 2013, 4 @entity1 with the knee @entity2720 and free bone fragments were treated with arthroscopy to detect the stripped cartilage, and then the cartilages were reduced with small incision and fixed by cartilage nail. There were 3 males and 1 female, with age of 15, 15, 20 and 27 years old. The durations of the disease were 1 d, 5 d, 1 month and 1 year. All the @entity1 had @entity4 and effusion in the knee joint, and the floating patellar test was positive. CT examination showed @entity79 and loose bodies. The Lysholm, VAS, and Tegner scale were used to evaluate the knee joint functions before and after operation. RESULTS: All the @entity1 underwent successful surgery. Postoperative CT showed good location of the cartilage without loss of reduced bone and cartilage. All the @entity1 were followed up, and the duration ranged from 10 to 13 months, with a mean of 12 months. In one @entity1 , arthroscopy examination was conducted for a second time to examine the connection of the @entity174 part to the surrounding cartilage, and it showed that the internal fixator was not absorbed. The Lysholm, VAS and Tegner scale of all @entity1 were better than those before operation. CONCLUSION: Treatment of @entity75 with the fixation of absorbable cartilage nails may reconstruct the integrity of articular surface and recover the stability of joints, and it is an effective treatment method.
