关节与肌肉是维持人体正常运动功能必不可少的两部分，肌少症会导致关节置换术后康复效果降低。本研究对全关节置换患者肌少症的相关研究进行范围审查，以范围综述方法学为指导，计算机检索中国知网、万方数据库、中国生物医学文献数据库、Web of Science、PubMed、护理学全文数据库（CINAHL）、Cochrane Library数据库，检索时限为建库至2024年4月1日，由两名研究生筛选文献、汇总和系统分析。最终纳入19篇文献。全关节置换患者术前肌少症发生率为1.3%～35.5%，主要应用SARC-F和小腿围进行筛查。患者肌少症的影响因素包括社会人口学、躯体状态、生物标志物、合并症等因素。干预方法包括运动干预、营养补剂干预、中医干预与多学科综合干预等。全关节置换患者术前肌少症发生率不等，受多种因素影响，未来还需要验证肌少症预测模型的稳定性，加强在全关节置换患者中的本土化筛查工具研究，及时识别全关节置换患者术前肌少症。

Joint and muscle function are essential for normal human movement， and sarcopenia can compromise post-joint replacement rehabilitation. This study conducted a scoping review of sarcopenia in patients undergoing total joint arthroplasty. Guided by scoping review methodology， the following data bases were searched：the China National Knowledge Infrastructure， Wanfang Database， Chinese Biomedical Literature Database， Web of Science， PubMed， Cumulative Index to Nursing and Allied Health Literature（CINAHL），and Cochrane Library from inception to April first， 2024. Two graduate students screened， summarized， and systematically analyzed the literature， ultimately including 19 studies. The prevalence of sarcopenia in preoperative total joint arthroplasty patients ranged from 1.3% to 35.5%， primarily assessed using SARC-F and calf circumference. Influencing factors included sociodemographic， physical status， biomarkers， and comorbidities. Interventions involved exercise， nutritional supplements， traditional Chinese medicine， and multidisciplinary approaches. The varying prevalence and influence of multiple factors highlight the need for further validation of sarcopenia prediction models and the development of culturally appropriate screening tools for timely identification of sarcopenia in total joint arthroplasty patients.
