Dear editor, With great interest, we have read the article: BIs there any difference between open and arthroscopic treatment for osteochondritis dissecans (OCD) of the humeral capitellum: a systematic review and meta-analysis^ written by Lu et al. [1]. Based on this meta-analysis of ten studies including 142 patients, the authors conclude that both open and arthroscopic lesion debridement with fragment fixation can be successful in treating unstable OCD. Arthroscopy may be a better option than the open procedure, but high-level evidence is needed to determine the superiority of arthroscopic techniques over open procedure in treating elbow OCD. We think however that this relevant work but its conclusion should be interpreted in light of some limitations. The authors already concluded and discussed that there were differences in baseline characteristics such as the age at time of surgery, gender and number of dominant elbows. Also, many different fixation techniques were applied in these arthroscopic and open procedures.
