Biologic Augment of the Medial Patellofemoral Ligament to Reduce Recurrence After Primary Lateral Patellofemoral Dislocation

What this Trial Is About

This research aims to evaluate whether repairing the medial patellofemoral ligament (MPFL) with the help of a Biobrace4 implant can reduce the chance of the kneecap dislocating again after a first-time patellofemoral dislocation. Patellofemoral dislocation is a common knee injury, especially in young people, with recurrence rates varying widely depending on individual risk factors. Current treatments vary, and no clear consensus exists on the best approach to prevent repeat dislocations in patients with mild to moderate risk. Participants will undergo a surgical procedure within 7 days of their first lateral patellofemoral dislocation. This involves knee arthroscopy combined with MPFL repair that is enhanced by a synthetic Biobrace4 ligament designed to support both mechanical strength and biological healing. This intervention is being studied to see if it better maintains the kneecap's position during healing compared to natural outcomes without surgery. During the study, participants will be monitored for up to two years to assess if the patella dislocates again. Assessments include physical tests such as single-leg hop and balance, muscle strength measurements, and patient-reported outcome questionnaires related to knee instability, pain, medication use, and psychological factors. Close follow-up in the initial two weeks will monitor pain and medication use, while longer-term evaluations will focus on knee function and stability.
