Comment on Hu et al.: Allograft versus autograft for anterior cruciate ligament reconstruction: an up-to-date meta-analysis of prospective studies.

摘要

We have read the article titled "Allograft versus autograft for anterior cruciate ligament reconstruction: an up-to-date meta-analysis of prospective studies" by Hu et al. [1] with great interest.In this meta-analysis, the authors compared clinical efficacy of allograft with autograft for anterior cruciate ligament reconstruction. They concluded that few significant differences are identified between the two methods. However, we have several queries which we would like to communicate with the authors.
