Inclusion criteria

Inclusion criteria: Complete consolidation of the fracture, implant in place at the time of measurement, medical clearance for sports activities, planned removal of the intramedullary nail independent of the study, if histological examination of the tendon is performed, the nail must have been inserted via a transpatellar approach.
