I read with great interest an article titled “Comparison of clinical outcomes between arthroscopic debridement and conservative treatment of primary adhesive capsulitis of the hip” by Lim et al. [1] published in the June 2020 issue of the journal and would like to congratulate the authors for their study. Authors performed a retrospective case-control study that assessed the clinical outcomes and change of range of motion (ROM) between patients with adhesive capsulitis of hip (ACH) who underwent arthroscopic capsular release (ACR) and those who underwent conservative treatment at a minimum follow-up of two years. Although they have touched a highly pertinent topic in a scientific manner, the study has brought important issues that I would like to communicate with the authors.
