Efficacy of total hip arthroplasty for the treatment of patients with femoral head avascular necrosis: A protocol for systematic review and meta-analysis.

ABSTRACT

BACKGROUND: Femoral head avascular necrosis (FHAN) is a very common condition among elderly population. Previous studies have reported that total hip arthroplasty (THAP) can benefit patients with such condition. However, no study systematically addressed this topic. Thus, this study will systematically explore the efficacy and safety of THAP for the treatment of patients with FHAN. METHODS: We will search the following electronic bibliographic databases from inception to the February 29, 2020 MEDLINE, EMBASE, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, China National Knowledge Infrastructure, and Chinese Scientific Journal Database. Randomized controlled trials of THAP for the treatment of patients with FHAN will be included, which were reported in any language. All process of study selection, data collection, and study quality assessment will be performed independently by 2 authors independently. Any divergences will be solved by discussion with another author. RevMan 5.3 software will be carried out for data synthesis and analysis. RESULTS: This study will provide a detailed summary of current evidence related to the efficacy and safety of THAP for the treatment of patients with FHAN through assessing pain intensity of hip or knee joints, function and limitation of attacked femoral head, health-related quality of life, and complications. CONCLUSION: The findings of this study may provide helpful guidance of THAP for the treatment of patients with FHAN. SYSTEMATIC REVIEW REGISTRATION INPLASY202040067.
