This study aims to evaluate the long-term clinical outcomes of arthroscopic trochleoplasty in patients treated for chronic recurrent patellar dislocations. The primary objective is to assess the effectiveness of the procedure in reducing the need for re-operations and preventing recurrent instability. Secondary objectives include evaluating postoperative complications, patellofemoral pain, functional outcomes using the Kujala Anterior Knee Pain Scale (AKPS), and quality of life measured by EQ-5D-5L. This retrospective cohort study will analyze data from patient records and structured telephone interviews conducted at least one year post-surgery.
