自体移植前交叉韧带重建时，切取髌腱中央三分之一被认为会损害股四头肌的力量和功能。我们比较了自体髌腱移植或同种异体前交叉韧带重建后运动员股四头肌力量和功能能力的客观测量。我们观察了33例活跃的男性患者（平均年龄24.3岁），他们在12至24个月前使用髌腱自体移植物（N = 15）或同种异体移植物（N = 18）技术进行了前交叉韧带重建。所有患者均接受了强化康复治疗。通过测量60和240度/秒时的峰值扭矩、240度/秒时的扭矩加速度能量和使用Cybex II等速测试装置的四头肌指数来评估四头肌强度和功率。根据3项专门设计的功能性能测试和跳频测试的结果评价功能能力。结果显示，自体移植物组和同种异体移植物组在这些参数方面没有显著差异。这些结果表明，在进行强化康复的高度活跃患者中，采集髌腱中央三分之一用于自体移植前交叉韧带重建不会降低股四头肌的力量或功能能力。因此，建议避免自体髌腱移植前交叉韧带重建，以保持股四头肌的力量和功能能力可能是不必要的。
Harvesting the central third of the patellar tendon for autograft anterior cruciate ligament reconstruction is thought to compromise quadriceps strength and functional capacity. We compared objective measurements of quadriceps strength and functional capacity in athletes after patellar tendon autograft or allograft anterior cruciate ligament reconstruction. We looked at 33 active male patients (mean age, 24.3 years) who had anterior cruciate ligament reconstructions 12 to 24 months earlier using patellar tendon autograft (N = 15) or allograft (N = 18) techniques. All patients underwent an intensive rehabilitation program. Quadriceps strength and power were assessed by measuring peak torque at 60 and 240 deg/sec, torque acceleration energy at 240 deg/sec, and the quadriceps index using a Cybex II isokinetic testing device. Functional capacity was evaluated based on the results of 3 specially designed functional performance tests and the hop test. Results revealed no significant difference between autograft and allograft groups with respect to any of these parameters. These findings indicate that harvesting the central third of the patellar tendon for autograft anterior cruciate ligament reconstruction does not diminish quadriceps strength or functional capacity in highly active patients who have intensive rehabilitation. Thus, the recommendation to avoid patellar tendon autograft anterior cruciate ligament reconstruction to preserve quadriceps strength and functional capacity may be unnecessary.
