目的：本研究的目的是研究在前交叉韧带重建中收获1或2个腘绳肌肌腱后的腘绳肌强度。研究方法：我们招募了50名在前交叉韧带重建手术后平均32.5个月恢复定期体育活动的个体参加比较研究（半腱肌-股薄肌组30名，半腱肌组20名）。测量等速腘绳肌力量（在60 °/s和180 °/s下，记录峰值扭矩和在60 °、90 °和105 °膝关节屈曲时产生的扭矩）和等长腘绳肌力量（在30 °、90 °和105 °膝关节屈曲时），并使用站立膝关节屈曲角来评价功能性腘绳肌力量恢复。结果如下：两组之间在任何等长或等速力量测量或站立膝关节屈曲角度方面均无显著差异。在膝关节屈曲105 °时，站立膝关节屈曲角度和等长腘绳肌力量结果之间没有发现相关性（r（2）= 0.034）。结论：这些研究结果表明，选择腘绳肌腱移植物，即单独半腱肌或半腱肌和股薄肌，不太可能显着影响术后恢复运动的运动员术后腘绳肌腱强度的结果。两种移植物的选择显示，与非手术肢体相比，力量不足3%至27%，表明尽管成功完成康复，但腘绳肌力量不足仍然存在。结果还表明，站立膝关节屈曲角度不应作为替代临床测量腘绳肌力量。证据等级：III级，回顾性比较研究。
Purpose: The purpose of this study was to investigate hamstring strength after harvest of 1 or 2 hamstring tendons for anterior cruciate ligament reconstruction. Methods: We recruited 50 individuals who had returned to regular sporting activity to participate in a comparative study at a mean of 32.5 months after anterior cruciate ligament reconstructive surgery (30 in semitendinosus-gracilis group and 20 in semitendinosus group). Isokinetic hamstring strength (at 60 degrees/s and 180 degrees/s with the peak torque and torque produced at 60 degrees, 90 degrees, and 105 degrees of knee flexion recorded) and isometric hamstring strength (at 30 degrees, 90 degrees, and 105 degrees of knee flexion) were measured, and the standing knee flexion angle was used to evaluate functional hamstring strength recovery. Results: No significant differences between the groups were found in any of the isometric or isokinetic strength measures or in the standing knee flexion angle. No relation was found between the standing knee flexion angle and the isometric hamstring strength results obtained at 105 degrees of knee flexion (r(2) = 0.034). Conclusions: These findings show that the choice of hamstring tendon graft-that is, semitendinosus alone or semitendinosus and gracilis-is unlikely to significantly influence postoperative hamstring strength outcomes in athletes returning to sports postoperatively. Both graft choices showed strength deficits of between 3% and 27% compared with the nonoperated limb, indicating that hamstring strength deficits persist despite successful completion of rehabilitation. The results also show that the standing knee flexion angle should not be used as a surrogate clinical measure of hamstring strength. Level of Evidence: Level III, retrospective comparative study.
