Evaluating an early functional rehabilitation approach for flexor tendon repairs in the context of current concepts ABSTRACT Background: In recent years, an increase in scientific research on the post-treatment of flexor tendon repairs has been observed. To evaluate the effectiveness and safety of the "Early-Active-Motion" concept that has been used in our clinic for over 10 years, a prospective study was developed that detailed both functional outcomes and complication rates over a period of 3 months.90 flexor tendon repairs in Zones 1-3, with and without accompanying injuries, were examined after three, six, nine and 12 weeks. Compliance was not a reason for exclusion. The collected parameters included the DASH, finger mobility according to the Strickland-Score, and other assessments.Out of a total of 90 flexor tendons, follow-up was achieved on 67 over a period of three months. Overall, 43 of the tendons achieved an excellent or good outcome. 20 had a fair outcome, and 4 of the digits had a poor Strickland Score. A total of three ruptures were documented.The "Early-Active-Motion" concept achieves a functionally good outcome with a Strickland-Score of 76 points. It is applicable from Zone 1 to Zone 3, even in complex flexor tendon injuries. Early phase deterioration appears to be an indicator of lower final outcomes.
