Official title
Evaluering av Kliniske Resultater Hos Pasienter Operert for Kronisk Residiverende Patellaluksasjoner Ved Hjelp av Artroskopisk Stabilisering Med Trokleaplastikk. En Kvalitetskontroll-studie
Overview
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.
Primary outcome measures
- Re-operation Rate [Time frame: The investigators seek to register any re-operations from the time between the index surgery and the interview, ranging from 1 year up to 7 years postoperatively.]
Secondary outcome measures (6)
- Recurrent Instability Rate [Time frame: The investigators seek to register any incidences of recurrent instability from the time between the index surgery and the interview, ranging from 1 year up to 7 years postoperatively.]
- Postoperative Complications [Time frame: The investigators seek to register any complications related to the index surgery from the time between the index surgery and the interview, ranging from 1 year up to 7 years postoperatively.]
- Functional Outcome [Time frame: At the time of the interview, which will be performed from 1 year up to 7 years postoperatively.]
- EQ-5D-5L (HRQoL) scores [Time frame: At the time of the follow-up interview, which will be performed from 1 year up to 7 years postoperatively.]
- Pain Assessment [Time frame: At the time of the follow-up interview, which will be performed from 1 year up to 7 years postoperatively.]
- Patient Satisfaction [Time frame: At the time of the follow-up interview, which will be performed from 1 year up to 7 years postoperatively.]
