Identification of Kinematic Variables Specific of Patellar Tendinopathy in Athletes at Risk

France60 participantsStarted 2026-05-01

Plain-language summary

This research aims to identify and monitor specific kinematic markers associated with patellar tendinopathy in athletes at risk. Using a markerless motion capture system, vertical jump tests will be analyzed to detect early biomechanical changes in the knees, hips, trunk, and ankles. By comparing injured participants, the study seeks to improve early diagnosis and personalized prevention strategies for patellar tendinopathy.
