About this trial
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.

Treatments tested in this trial
The intervention consists of a series of vertical jump tests captured using high-resolution cameras with markerless motion capture technology.
Diagnostic testParticipants will undergo clinical evaluations including the Single Leg Decline Squat (SLDS) test, VISA-PF, OSTRC-P questionnaires, and Doppler ultrasound of the patellar tendon. These assessments will take place at baseline (T0) and follow-up periods (M3, M6, M9, M12) to track the evolution of kinematic markers and clinical symptoms related to patellar tendinopathy.
The intervention consists of a series of vertical jump tests captured using high-resolution cameras with markerless motion capture technology at 6 months and 12 months
