摘　　要：目的 :观察可吸收软骨钉多点固定治疗髌骨不稳所致骨软骨骨折的疗效。方法 :自2014年8月至2016年9月收治21例髌骨脱位所致骨软骨骨折患者,其中男7例,女14例;年龄12~42岁,平均27岁。采用开放手术找到游离软骨骨折块,行可吸收软骨钉内固定术联合外侧支持带松解内侧支持带紧缩术治疗。术前、术后随访行Lysholm评分评定膝关节功能,对数据进行回顾性分析。结果:所有患者手术顺利,术后随访8~22个月,平均12个月。术后CT及X线检查示骨折块位置良好。21例患者均基本恢复伤前运动水平,膝关节Lysholm评分达86.11±4.97。结论:由髌骨不稳所致骨软骨骨折采用可吸收软骨钉能有效固定游离软骨块,操作简单、疗效满意,具有良好的临床推广意义。Objective：To study clinical effects of multi point fixation with bioabsorbable cartilage screws for the treatment of osteochondral fracture caused by patellar instability. Methods：During the period from August 2014 to Steptember 2016,there were 21 patients with osteochondral fracture caused by patellar dislocation,including 7 males and 14 females,ranging in age from 12 to 42 years old,with an average of 27 years old. During the operation,free fractures fragments of cartilage were found with a open surgery,and the patients were treated with fixation by absorbable cartilage screws combined with lateral retinaculum release and medial retinaculum shrinkage. The Lysholm scoring scale was used to evaluate the knee joint functions before and after operation. The retrospective study analyzing the data was carried out. Results：All the patients underwent successful surgeries and were followed up with a mean period of 12 months（ranged,8 to 22 months）. The CT and X ray examinations were performed after the operation which showed the fracture fragments were on good positon. The exercise level in all the patients basically returned to the pre injury level. The postoperative Lysholm score was 86.11 ±4.97. Conclusion：The absorbable cartilage nail can effectively fix the free cartilage fragments of the osteochondral fracture due to the patellar instability,which is a simple operation,and worthy of clinical promotion.
