JUPITER 4.0 - Risk Factors for Failure of Isolated Medial Patellofemoral Ligament Reconstruction
Hospital for Special Surgery, New York
Summary
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.
Description
The JUPITER group consists of high-volume patellofemoral surgeons across the United States, and was organized to facilitate the collection of clinical and radiographic outcomes following surgical and non-surgical treatment of patellar instability. With this study (JUPITER 4.0), the group aims to prospectively enroll a new cohort of consecutive patients with recurrent patellar instability that would undergo isolated MPFL reconstruction regardless of radiographic measurements or anatomic risk factors to address two specific aims - 1) what patient, injury, and surgical factors lead to recurrent i…
