Abstract:

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.
