Abstract

An in vitro canine model was used to compare suture methods (Kessler, modified Kessler, Savage, Lee, MGH) for repair of a partially lacerated flexor tendon. The isolated frictional resistance between the repaired flexor tendon and the A2 pulley and the strength of the suture repair for preventing gap formation were examined. Among the suture techniques, the modified Kessler had the lowest change in gliding friction from the normal tendons while MGH suture had the largest change. Overall, the running suture had the lowest change in friction. Considering the ultimate failure load, the modified Kessler technique was the strongest and the Lee method was the weakest. However, considering the resistance for gap formation, the MGH suture performed the best while the modified Kessler was the least resistant.
