To compare knee isokinetic performance six months after reconstruction of the anterior cruciate ligament using grafts from either the patellar tendon or the hamstrings among patients who underwent the same rehabilitation protocol.
Thirty-four patients were evaluated (17 with grafts from the patellar tendon and 17 with grafts from the hamstrings). Operated and non-operated knees were compared with regards to the variables of peak torque, work and the hamstring/quadriceps relationship at velocities of 60º/s and 180º/s and power of 180º/s after six months of surgery.
The patients with ACL reconstruction using the patellar tendon (BPTB) showed quadriceps deficits for all variables, but the flexor musculature was balanced. In the hamstring group, both the extensors and the flexors showed deficits for the variables analyzed, except for hamstring power at 180º/s.
Patients in the patellar tendon group had a greater quadriceps deficit compared with those in the hamstrings group. Patients in the hamstrings group had a greater muscular deficit in the flexor mechanism compared with the contralateral knee. An unbalanced H/Q ratio was observed regardless of graft type, but this was more evident in the BPTB group.
比较在接受相同康复方案的患者中,使用髌腱或腘绳肌移植物重建前交叉韧带6个月后的膝关节等速运动表现。
对34例患者进行评估(17例使用髌腱移植物,17例使用腘绳肌移植物)。在术后6个月,比较手术侧和非手术侧膝关节在60°/s和180°/s速度下的峰值扭矩、功以及腘绳肌/股四头肌关系变量,以及180°/s功率下的情况。
使用髌腱(BPTB)重建ACL的患者在所有变量上均表现出股四头肌功能缺陷,但屈肌肌肉系统是平衡的。在腘绳肌组中,除了180°/s时的腘绳肌功率外,伸肌和屈肌在分析的变量上均表现出功能缺陷。
与腘绳肌组患者相比,髌腱组患者的股四头肌功能缺陷更大。与对侧膝关节相比,腘绳肌组患者的屈肌机制存在更大的肌肉功能缺陷。无论移植物类型如何,均观察到H/Q比值不平衡,但在BPTB组中更为明显。
