Comment on “Postoperative creatine kinase elevation following hip arthroscopy and associated risk factors”

We read with great interest the recent article titled“Postoperative creatine kinase elevation following hip arthroscopy and associated risk factors” by Tonotsuka H (1). This retrospective study investigated the postoperative creatine kinase (CK) and risk factors for CK elevation after hip arthroscopy. Their findings suggested that CK levels should be monitored, especially in young patients and cases of prolonged duration of traction during hip arthroscopy. We really appreciated the work that has been done by the authors. However, there are some worthwhile issues we like to comment on.
