In this study we measured the effect on the muscle strength in the thigh in connection with diagnostic arthroscopy with central approach, arthroscopy with arthroscopic operation of bucket-handle ruptures, flap tears, total arthroscopic meniscectomy, and open meniscectomy. Thirty-seven patients were tested preoperatively and 1, 4 and 8 weeks postoperatively with a Cybex II isokinetic dynamometer. The extensor muscles of the knee joint were most affected. The flexor muscles were generally recovered in all groups within a month. Diagnostic arthroscopy and arthroscopic operations for bucket-handle ruptures showed no significant effect on the thigh muscle torque. With the other arthroscopic operations there was a 40% decrease of quadriceps function 1 week after operation. After 8 weeks normal function returned. Open meniscectomy had a much more negative effect on the quadriceps muscle with a decrease of about 70% after 1 week. After 8 weeks, the rehabilitation was still not complete.
在本研究中，我们测量了中央入路诊断性关节镜检查、桶柄状撕裂的关节镜手术、瓣状撕裂修复、全关节镜半月板切除术以及开放性半月板切除术对大腿肌肉力量的影响。37例患者在术前以及术后1周、4周和8周使用Cybex II等速测力计进行测试。膝关节伸肌受影响最大。屈肌在所有组中通常在1个月内恢复。桶柄状撕裂的诊断性关节镜检查和关节镜手术对大腿肌肉扭矩无显著影响。其他关节镜手术术后1周股四头肌功能下降40%。8周后恢复正常功能。开放性半月板切除术对股四头肌的负面影响更大，术后1周下降约70%。8周后，康复仍未完成。
