Locked Lateral Patellar Dislocation Reduced by Arthroscopic Procedure: A Case Report.

Most cases of patellar dislocation can be reduced spontaneously or manually without sedation. To date, only one case of arthroscopic reduction for a lateral locked patellar dislocation has been reported, with a short follow-up period. Herein, we report the case of a 22-year-old man with a lateral locked patellar dislocation for whom we performed arthroscopic reduction and repair of the medial structure, which stabilized the patella medially. The patient was followed up for five years postoperatively and experienced no recurrence of patellar dislocation or difficulties in daily life.
