Arthroscopic Trianchor With 6 Sets of Double-Pulley Suture Bridge Repair of Medium-Sized Supraspinatus Tendon Tears.

Currently, a suture bridge is a good way to treat medium-sized supraspinatus tendon tears. However, one medial-row anchor (double-loaded suture anchor) can only create 4 sets of suture-bridges, and overtension and reduced blood flow in the tendon caused by the knotted medial-row may lead to tendon retear. Therefore, we present a pragmatic suture-bridge technique called the trianchor double-pulley suture-bridge (DPSB). In the treatment of medium-sized supraspinatus tendon tears, using one medial-row anchor (double-loaded suture anchor) can create 6 sets of DPSBs, and more complete restoration of the footprint and increased failure load can be obtained from 6 sets of DPSBs. In addition, knotless medial-row can reduce tendon tension and improve vascular circulation.
