Hip exercises are frequently prescribed following knee injury and subsequent surgery based on the assumption that hip weakness exists. No data, however, are available that support hip weakness following knee trauma or surgery. Therefore, the purpose of this study was to compare hip strength in patients after knee surgery. Twenty-seven patients who had undergone unilateral knee surgery were tested for hip flexor, extensor, abductor, and adductor isometric strength prior to initiation of rehabilitation. Multivariate analysis of variance revealed significant hip weakness in all four hip muscle groups of the surgical extremities (11.9-25.3%, p < or = 0.05) when compared with nonsurgical extremities. Both peak and endurance force were affected. The greatest percent difference between the surgical and nonsurgical extremity occurred for hip extension peak (25.3%) and endurance (22.6%) force development. We recommend assessment of hip strength following knee surgery and appropriate resistive exercises if weakness exists.
基于存在髋部无力的假设，髋部锻炼常在膝关节损伤及后续手术后进行。然而，尚无数据支持膝关节创伤或手术后会出现髋部无力。因此，本研究的目的是比较膝关节手术后患者的髋部力量。27例接受单侧膝关节手术的患者在开始康复治疗前，接受了髋部屈肌、伸肌、外展肌和内收肌等长力量测试。多变量方差分析显示，与非手术侧相比，手术侧所有四个髋部肌肉群均存在明显的髋部无力（11.9 - 25.3%，p≤0.05）。峰值力和耐力均受到影响。手术侧与非手术侧之间差异百分比最大的是髋部伸展峰值（25.3%）和耐力（22.6%）力量发展。我们建议在膝关节手术后评估髋部力量，若存在无力则进行适当的抗阻训练。
