The purpose of this study was to evaluate the peak torque of the knee flexors (H) and the quadriceps muscle (Q) at 12 and 24 weeks after isolated anterior cruciate ligament reconstruction with semitendinosus and gracilis autografts.
There were 20 patients (8 females, 12 males), with the mean age of 31.5 years. An isokinetic examination of the muscles was performed with a Biodex System 3 isokinetic dynamometer at a speed of 180 degrees/sec. All patients underwent 12 weeks of isokinetic training for 20 minutes 5 times a week (240 degrees/sec for 6 weeks and 180 degrees/sec for 6 weeks) beginning 12 weeks after surgery.
The average peak torque difference between the healthy and operated limb at 12 and 24 weeks postoperatively was 38% and 14% for Q and 25% and 4.3% for H respectively. The decrease in peak torque differences was statistically significant for both H and Q (p=0.05). The decrease in Q peak torque was significantly higher than that of H peak torque 12 and 24 weeks after surgery.
These results indicate that 12-week isokinetic training can increase the peak torque of H and Q by 20% and 24% respectively. An isokinetic examination of Q and H peak torques should become a standard procedure for evidence-based monitoring of the rehabilitation process after anterior cruciate ligament reconstruction.
本研究的目的是评估采用半腱肌和股薄肌自体移植物进行孤立性前交叉韧带重建术后12周和24周时，屈膝肌（H）和股四头肌（Q）的峰值扭矩。
共有20例患者（8例女性，12例男性），平均年龄31.5岁。使用Biodex System 3等速测力计以180度/秒的速度对肌肉进行等速检查。所有患者在术后12周开始进行为期12周的等速训练，每周5次，每次20分钟（6周为240度/秒，6周为180度/秒）。
术后12周和24周时，健康肢体与手术肢体的平均峰值扭矩差异，Q分别为38%和14%，H分别为25%和4.3%。H和Q的峰值扭矩差异降低具有统计学意义（p = 0.05）。术后12周和24周时，Q的峰值扭矩下降明显高于H的峰值扭矩下降。
这些结果表明，12周的等速训练可使H和Q的峰值扭矩分别增加20%和24%。对Q和H峰值扭矩进行等速检查应成为前交叉韧带重建术后基于证据的康复过程监测的标准程序。
