Arthroscopic Excision of Bipartite Patella With Preservation of Lateral Retinaculum in an Adolescent Ice Hockey Player.

Bipartite patella usually is an asymptomatic anatomical variant. However, in some adolescent athletes, it causes anterior knee pain, resulting in decreased participation and performance. We report the case of a high-level adolescent ice hockey player who underwent successful arthroscopic excision with preservation of the lateral retinaculum of a symptomatic bipartite patella after failed nonoperative treatment. The patient returned to play by 6 weeks, and 31-month subjective follow-up scores showed high satisfaction and good clinical outcomes. For patients with a symptomatic bipartite patella, arthroscopic surgery is a good option for reducing pain and returning the athlete to competition.
