Although both sarcopenia and hip disease decrease physical function, few studies have investigated the association. We investigated the prevalence of sarcopenia in patients awaiting total hip arthroplasty for osteoarthritis and examined the impact of sarcopenia on pre- and postoperative outcomes.
This prospective study included 96 females. Participants were classified using two criteria. Cases defined as having sarcopenia by the Asian Working Group for Sarcopenia (AWGS) criteria were categorized as the AWGS-sarcopenia (A-S) group, and others were categorized as the AWGS-non-sarcopenia (A-NS) group. Those classified by hand grip strength (HGS) constituted the lower-HGS (L-H) and normal-HGS (N-H) groups. Patient demographics, physical function, and Japanese Orthopaedic Association (JOA) score were compared between each group.
The prevalence of the AWGS sarcopenia was 33.3%. In the pre- and postoperative analyses, the L-H group had significantly poorer physical function and JOA score than the N-H group. Postoperatively, the A-S group only demonstrated poorer HGS.
Preoperative physical function and JOA score was significantly poorer in the L-H group; physical function was significantly poorer even postoperatively. A HGS test is useful for detecting a decline in the pre- and postoperative physical function in females with hip osteoarthritis.
尽管肌少症和髋关节疾病都会降低身体功能，但很少有研究调查它们之间的关系。我们调查了骨关节炎患者接受全髋关节置换术时肌少症的患病率，并研究了肌少症对术前和术后结果的影响。
本前瞻性研究纳入了 96 名女性。参与者使用两种标准进行分类。根据亚洲肌少症工作组（AWGS）标准定义为肌少症的病例被归类为 AWGS 肌少症（A-S）组，其他病例被归类为 AWGS 非肌少症（A-NS）组。根据握力（HGS）进行分类的患者构成低 HGS（L-H）和正常 HGS（N-H）组。比较各组患者的人口统计学、身体功能和日本骨科协会（JOA）评分。
AWGS 肌少症的患病率为 33.3%。在术前和术后分析中，L-H 组的身体功能和 JOA 评分明显低于 N-H 组。术后，A-S 组仅 HGS 较差。
L-H 组术前身体功能和 JOA 评分明显较差；即使术后，身体功能仍明显较差。握力测试对于检测髋关节骨关节炎女性术前和术后身体功能下降很有用。
