Platelet-rich plasma combined with microfracture versus microfracture in the treatment of knee cartilage lesions: A meta-analysis / 中国组织工程研究

ABSTRACT

OBJECTIVE: A large number of recent studies reported that microfracture combined with platelet-rich plasma has a good effect on osteochondral injury. This study systematically evaluated the clinical effect of arthroscopic platelet-rich plasma combined with microfracture versus microfracture in the treatment of knee cartilage lesions. METHODS: A randomized controlled trial of arthroscopic platelet-rich plasma combined with microfracture in the treatment of knee cartilage lesions was searched in CNKI, Wanfang Database, VIP Database, Chinese Biomedical Literature Database, PubMed, Embase and Cochrane Library. The date was from January 2001 to March 2020. The data were extracted and the quality of the included literature was evaluated, and the Rev-Man5.3 software was used for meta-analysis. RESULTS: (1) A total of seven randomized controlled trials were included, and the modified Jadad scale results showed that the scores of four studies were ≥ 4, which were high-quality literatures, and the scores of three studies were 0.05). CONCLUSION: Platelet-rich plasma combined with microfracture for knee cartilage lesions can reduce the pain in the short and medium terms, enhance the joint function in the medium and long terms, and improve the postoperative experience. However, due to the limited number of included articles, more large-sample and high-quality randomized controlled trials are needed to provide further effective data.
