“…The idea of early primary tendon repair and mobilization to permit a smooth gliding surface has become a standard part of management of tendon injuries. 34,60,61 As knowledge of the changes that take place in tenotomized muscle increases, it is increasingly apparent that the timing of tendon repair is extremely important to prevent these molecular and structural events. Delay in tendon repair may affect the ability to achieve normal length and function as a result of muscle contracture and atrophy.…”

“…The roles of various factors such as suturing technique, suture material (12), and postoperative rehabilitation regimens have been investigated in order to reduce such adhesions. Of these, postoperative passive mobilization has been the most extensively investigated, both clinically (6,14,20,21) and experimentally (7,8,10,11,15,22). Laboratory studies indi-cate that protected passive motion of the healing tendon not only helps to decrease the amount of adhesions between the tendon and the surrounding sheath, but also improves flexor tendon healing by increasing its strength.…”

The most common problem following primary flexor tendon repair is the failure of the tendon apparatus to glide, secondary to the formation of adhesions. Early motion following tendon repair has been shown to be effective in reducing adhesions between the tendon and the surrounding sheath. Therefore, it is important to determine the amount of flexor tendon excursion along the digit during joint motion. In this study, the excursion between the flexor digitorum profundus (FDP) tendon and the sheath was examined in both human and canine digits. Based on roentgenographic measurements and joint kinematic analysis, the motion of the bones, the FDP tendon, and the sheath were measured with respect to joint rotations. It was found that the canine flexor tendon apparatus behaved similarly to that of the human for the motions studied. The amount of tendon excursion was very small in regions distal to the joint in motion (approximately 0.1 mm/10 degrees of joint rotation). There was little displacement of the sheath (0.2-0.3 mm), except at the metacarpal joint region during metacarpophalangeal (MCP) joint motion and at the proximal interphalangeal (PIP) joint region during PIP joint motion. Tendon excursion relative to the tendon sheath was the largest in zone II during PIP joint rotation (1.7 mm/10 degrees of joint rotation). These results suggest that PIP joint motion may be most effective in reducing adhesions following tendon repair in zone II.

“…On the other hand, there are studies in which stabilization or a slight increase is seen right from the start of the repair, followed by a more accentuated increase six weeks after the operation. Despite significant methodological differences and differences in the subjects between these studies, which creates difficulty and limitations regarding comparisons between the results, there are indications that after a six-week period, greater recovery of mechanical properties occurs, compared with the immediate postoperative period (7)(8)(9)(10)(11)(12)(13) . The analysis on the values of the mechanical properties of the tendons that were operated, in comparison with the contralateral controls, indicated the degree of recovery of mechanical behavior.…”
