Plain-language summary

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.

Inclusion Criteria: * patient diagnosed with patellar instability with conservative or surgical treatment * fluent in both spoken and written French Exclusion Criteria: * Patients who are unable to understand and/or respond to the questionnaire * Patients with another diagnosis or knee pathology under study (e.g., complex ligament tear of the knee, gonarthrosis) * Patients with another diagnosis or lower limb pathology under study with secondary functional impairment (e.g., coxarthrosis) * Patients with a change in the condition of the lower limb under study a. Exclusion from test-retest reliability calculations if symptoms of patellofemoral instability worsen or if there is new involvement of this lower limb between T0 and T1 b. Exclusion from response to change calculations if new involvement of the lower limb (e.g., ipsilateral lower limb trauma) occurs after treatment, i.e., between T0 and T2 * Patients answering fewer than 19 questions (out of 23 questions)
