At present, the repair patterns for medium-sized supraspinatus tendon tears are double- and single-row repairs. However, the limitations of double-row repair include excessive anchor implantation and incremental surgical cost and time, whereas a deficient tendon-bone contact area exists with single-row repair. The modified double-pulley suture-bridge repair presented in this study is an arthroscopic technique using 3 double-loaded suture anchors combined with a double-pulley technique to form a hybrid repair pattern with a double row as the mainstay and a single row as the supplement. In the treatment of medium-sized tendon tears, the modified double-pulley suture-bridge repair can not only maximize the tendon-bone contact area but also lower the surgical cost and shorten the operative time. The surgical technique is described, including pearls and pitfalls, as well as advantages and disadvantages.
