Objectives: This study aims to evaluate the tenolysis rates of zone 2 flexor digitorum profundus (FDP) with flexor digitorum superficialis (FDS) tendon repairs using four -strand technique and early passive motion exercises. Patients and methods: In this retrospective study, we performed zone 2 flexor tendon repairs in 149 patients (117 males, 32 females, mean age 33.3?12.9 years; range, 13 to 72 years) (82 right and 67 left hands) between November 2014 and January 2019. A total of 194 FDP and FDS tendons were repaired primarily by using modified Kessler and Bunnell methods. Patients underwent pure passive motion protocols after surgery according to modified Duran?s protocol. No active flexion components were added until postoperative fourth week. Results: Twenty-three out of 149 patients and 28 out of 194 fingers (14.43%) had tenolysis. There was no significant relationship between the number of operated fingers, gender, and tenolysis rate (p=0.836, p=0.584, respectively). Conclusion: The repair of the FDP with FDS tendon increases the tenolysis rate in zone 2. The tenolysis rate does not change according to the number or distribution of injured fingers and gender of the patient.
