Normal ranges for knee rotation in competitive pivot-sport athletes

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 is a multicenter observational effort combining retrospective and prospective data collection at two French sports medicine centers between 2022 and 2026. Healthy male and female athletes aged 15+ who compete in pivot sports will have overall (internal + external) knee rotational amplitudes measured using standardized clinical/dynamic arthrometer methods. Participants with prior knee ligament, meniscus, cartilage or bone injuries, current knee symptoms, or prior knee surgery are excluded. The goal is to define normative rotation ranges to help distinguish natural laxity from pathology.
