JUPITER 4.0 - Risk Factors for Failure of Isolated Medial Patellofemoral Ligament Reconstruction

The goal of this observational study is to learn about the outcomes of medial patellofemoral ligament (MPFL) reconstruction for the treatment of recurrent patellar instability. The main questions it aims to answer are: * What are the risk factors for recurrent patellar instability after MPFL reconstruction? * What functional outcomes do patients report after MPFL reconstruction? Participants undergoing MPFL reconstruction will answer survey questions about their knee and activity level 1 year and 2 years after surgery.

Pediatric and Adolescent Patellar Instability

This is a multi-center, randomized controlled clinical trial, the purpose of which is to determine if patients age 25 and younger who undergo medial patellofemoral ligament (MPFL) reconstruction have lower rates of recurrent instability compared to those treated non-operatively. The MPFL is a ligament that stabilizes the kneecap, and maintains its proper position in the groove on the femur (thighbone). Instability refers to a situation in which the kneecap moves out of place, or dislocates. When instability is recurrent, it occurs more than once in the same knee.

Comparison of Dynamic and Static Medial Patellofemoral Ligament Operation Technique for Recurrent Patellar Dislocation

This study is to evaluate whether the dynamic Medial Patellofemoral Ligament (MPFL) reconstruction as described by Becher is a successful operation technique to prevent patella instability and restore quality of life. It is to assess and compare clinical and functional outcomes of dynamic and static medial patellofemoral ligament reconstruction

French Version of the Banff Patellar Instability Instrument 2.0

There are several treatment options for patellofemoral instability, but no established guidelines currently exist. An important step toward developing a consensus is to examine the influence of each intervention through the collection of both subjective and objective outcomes. Most outcome measures commonly used for knee pathologies are primarily designed to monitor degenerative conditions (e.g., osteoarthritis) or ligamentous instability (e.g., anterior cruciate ligament rupture). Very few questionnaires are specific to patellar instability, a condition characterized by distinct signs and symptoms compared to other knee disorders. The Banff Patellar Instability Instrument (BPII) was developed with this gap in mind, in accordance with the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) criteria. This condition-specific tool is designed to subjectively assess the functional impact of patellofemoral instability on patients' quality of life, which is the most important factor in evaluating treatment success. Currently, there is no validated French-language outcome measure specific to patellofemoral instability. To improve patient care, the availability of such a validated tool in French is essential, both for clinical use and for conducting future research. To address this issue, the primary objective of this study is to translate the Banff Patellar Instability Instrument 2.0 (BPII 2.0) into French, following the three-step process described in the IQOLA project and in accordance with the guidelines outlined by the American Academy of Orthopaedic Surgeons (AAOS), and to evaluate its validity in a French-speaking population. Research Question Is the French version of the BPII 2.0 a valid tool to assess function in French-speaking patients diagnosed with patellofemoral instability? Specific Objectives To translate the Banff Patellar Instability Instrument 2.0 into French using a dual forward-backward translation process. To evaluate the psychometric properties of the French version of the BPII 2.0, including its reliability and validity.
