目的　对自体骨膜游离移植修复软骨缺损 ,重建半月板治疗膝骨性关节炎的方法、疗效进行评价。方法　 1996年～ 1999年 ,在膝关节清理术中清除病损软骨及退变碎裂的半月板 ,取胫骨骨膜游离移植修复软骨缺损 2 8例 36膝 ,其中重建半月板 8膝。术后早期在 CPM器上作连续被动功能锻炼 4周 ;半月板重建者术后石膏固定 7天。结果　术后全部病例均获 1～ 4年随访 ,采用主观症状、客观体征及 X线片三方面综合评价。术后膝关节功能优 2 2膝 ,良9膝 ,可 5膝 ,优良率为 86 .1%。结论　采用自体骨膜游离移植修复软骨缺损 ,重建半月板治疗膝骨性关节炎 ,近期可取得较好效果 ,远期效果尚需进一步研究。

REPAIR OF CARTILAGE DEFECT OF KNEE JOINTS WITH FREE PERIOSTEAL AUTOGRAFT

Objective To investigate the clinical application of periosteal autograft in repair of cartilage defect caused by osteoarthritis of knee. Methods From 1996 to 1999, 36 knees of cartilage defect of knee joint in 28 cases were treated. In the operation, the cracked degenerative cartilage was removed before free periosteum from tibia was transplanted to repair the defect, and the meniscuses in 8 knees of the 36 knees were reconstructed. After operation, early continuous passive movement was adopted for 4 weeks, and 8 knees with reconstruction of the meniscus were immobilized by plaster splint for 7 days after operation and before passive movement. All of the cases were followed up for 1 to 4 years before clinical evaluation in symptoms, signs and radiological findings. Results The general satisfactory rate was 86.1%, in which the function was excellent in 22 knees and good in 9 knees. Conclusion The periosteal autograft is a good choice for repairing cartilage defect due to osteoarthritis, with a satisfactory outcome in the short term.
