a Removal of semitendinosus tendon, removal of residual muscle tissue and joining of the two ends of the tendon. Suturing with nonresorbable strength 2 sutures over a length of approximately 20 mm. Placing a stay-suture in the tendon loop at the other end of the double tendon and determining the diameter of the 4-way transplant. b Selection of the T-lock in accordance with the determined transplant diameter and passing the transplant through the large hole of the implant. A four-way transplant is created. c Fixation of the tendon loop through the small hole of the implant with nonresorbable fibers (polyester strength 2). Suturing the distal end of the transplant with resorbable threads
