Hip Arthroscopy for Femoracetabular Impingement in China: A Review and Meta‐Analysis.

Objective: To explore the development of hip arthroscopy in China through reviewing the change of the application of hip arthroscopy operation on treating femoracetabular impingement (FAI). Method: Papers were retrieved from January 1, 2005 to November 1, 2019, from databases CNKI, Wanfang Data, VIP, PubMed, and Embase. The keywords are Hip Impingement, Femoroacetabular impingement, Hip arthroscopy, Arthroscopic operation, Hip Arthroscopy operation, and Arthroscope, etc. The quality of papers was assessed through MINORS , and statistics and meta‐analysis were performed by Word, Excel, and Revman 5.3 Zurich, Switzerland. Results: From a total of 8,953 papers, 46 review articles without data and 48 articles with data were involved, and 25 papers were included in the Meta‐analysis.

Overall, in China, the application of hip arthroscopy regarding FAI has flourished while maintaining a high level of treatment and has reached its peak in the past 2 years.
