Arthroscopic Trochleaplasty in Chronic Relapsing Patellar Dislocations: A Follow-up Study

Evaluering av Kliniske Resultater Hos Pasienter Operert for Kronisk Residiverende Patellaluksasjoner Ved Hjelp av Artroskopisk Stabilisering Med Trokleaplastikk. En Kvalitetskontroll-studie

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.

Inclusion Criteria:

• Patients aged 18 years and older.
• Underwent arthroscopic trochleoplasty for chronic recurrent patellar dislocations.
• Surgery performed between 2015 and 2023.
• Availability of follow-up data and consent for participation.

Exclusion Criteria:

• Concurrent knee surgeries unrelated to trochleoplasty.
• Previous surgeries on the same knee.
• Other significant orthopedic conditions affecting the knee.
• Lack of follow-up data or consent.
