We read with great interest the article "Closing-Wedge and Opening-Wedge High Tibial Osteotomy as Successful Treatments of Symptomatic Medial Osteoarthritis of the Knee: A Randomized Controlled Trial" by Mohammadreza Safdari et al . We appreciate the authors' efforts to describe the efficacy of high tibial osteotomy as a treatment for medial osteoarthritis of the knee. However, we had several concerns about the study results and believe that the authors' responses may help to address them.
