Kinematic markers of patellar tendinopathy in at-risk athletes using markerless motion capture

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter prospective cohort study uses a markerless motion capture system to analyze vertical jump tests in athletes at risk for patellar tendinopathy. Participants undergo clinical assessments, imaging, and patient-reported scores, followed by standardized jump tasks at 6 and 12 months to identify early biomechanical changes. The goal is to find kinematic indicators that predict onset and guide personalized prevention strategies. The study compares athletes who develop patellar tendinopathy with those who remain non-tendinopathic to assess diagnostic potential. Location is Montpellier, France, led by University Hospital, Montpellier, with collaboration from sports medicine and traumatology services.
