Abstract

Objective: Regaining hip and knee muscle strength is important after total hip arthroplasty (THA). However, it is unclear if muscles other than those of the operated hip also lose strength. This study aimed to identify deficits in hip and knee strength on the surgical and nonsurgical sides in female patients up to 12 months after THA.

Methods: Participants were 91 female patients who had hip osteoarthritis and underwent unilateral THA. Forty-six community-dwelling women who were asymptomatic were selected as control participants. Patients with locomotor disorders or postsurgical complications were excluded. Maximal isometric strength of the hip flexors, extensors, and abductors and knee extensors and flexors on the surgical and nonsurgical sides were measured before THA and 3, 6, and 12 months thereafter.

Results: Twelve months after THA, hip flexion, extension, and abduction strength on the surgical side were 84.6%, 83.5%, and 76.2%, respectively, of those in individuals who were asymptomatic; at the same time point, those on the nonsurgical side were 94.8%, 83.9%, and 79.4%, respectively. Knee extension strength on the surgical side was 89.3% of that in individuals who were asymptomatic. Compared to individuals who were asymptomatic, nearly all muscles showed significantly lower strength on both sides up to 6 months after THA.

Conclusion: At 12 months after THA, hip and knee strength on both the surgical and nonsurgical sides did not recover to the level observed in individuals who were asymptomatic. In particular, hip abductor strength on the surgical and nonsurgical sides were 76% and 79%, respectively, of that in individuals who were asymptomatic.

Impact: At 12 months after THA, hip and knee strength on the surgical and nonsurgical sides did not recover to the level observed in individuals who were asymptomatic, suggesting that the nonsurgical side may be inappropriate as a control to assess strength recovery on the surgical side.

识别全髋关节置换术后 12 个月妇女手术侧和非手术侧髋关节和膝关节肌肉力量的缺陷。

目的：全髋关节置换术（THA）后，恢复髋关节和膝关节肌肉力量非常重要。然而，目前尚不清楚除手术侧髋部肌肉外，其他肌肉是否也会失去力量。本研究旨在确定女性患者在全髋关节置换术后 12 个月内手术侧和非手术侧髋关节和膝关节肌力的缺陷：参与者为 91 名患有髋关节骨关节炎并接受单侧 THA 手术的女性患者。选择 46 名无症状的社区女性作为对照组。患有运动障碍或手术后并发症的患者被排除在外。在THA术前及其后3、6和12个月，测量了手术侧和非手术侧髋关节屈肌、伸肌和内收肌以及膝关节伸肌和屈肌的最大等长力量：THA术后12个月，手术侧髋关节的屈伸和外展力量分别是无症状者的84.6%、83.5%和76.2%；同一时间点，非手术侧的屈伸和外展力量分别是无症状者的94.8%、83.9%和79.4%。手术侧的膝关节伸展力量是无症状者的89.3%。与无症状者相比，THA术后6个月内，两侧几乎所有肌肉的力量都明显降低：结论：THA术后12个月时，手术侧和非手术侧的髋关节和膝关节力量都没有恢复到无症状者的水平。特别是手术侧和非手术侧的髋关节外展力量分别是无症状者的76%和79%：THA术后12个月时，手术侧和非手术侧的髋关节和膝关节力量没有恢复到无症状者的水平，这表明非手术侧可能不适合作为评估手术侧力量恢复的对照。
