Clinical Trial Summary

In order to gather enough data for meaningful statistics, a multicenter register of all flexor tendon repairs was established with surgical, clinical and rehabilitation patient data. The controlled active motion (CAM) protocol was administered in all patients after surgery. The purpose was to (i) measure surgery and therapy outcomes in the three centers and (ii) evaluate potential influencing factors on outcomes.
