Abstract: [Objective] To introduce the surgical technique and preliminary clinical outcome of arthroscopic repair of bony Bankart injury combined with rotator cuff tear with anchors. [Methods] From February 2018 to February 2022, a total 8 patients had bony Bankart injury and ipsolateral rotator cuff tear treated by arthroscopic repair with anchors. The posterior, anteroinferior and anterosuperior portals were established to repair the bony Bankart injury first. Single-row direct suture for small bone fragment and double-row double-pulley fixation for larger bone fragment were conducted with anchor sutures. After that, the anterolateral and posterolaterl portals were created to access the subacromial space, rotator cuff tear was repaired by single row suture with anchor. [Results] All patients had operations performed successfully and followed up for (39.7±4.6) months in a mean. Compared with those preoperatively, the VAS score [(6.9±1.2), (0.9±0.8), P 0.001], Constant-Murley score [(27.4±8.2), (90.8±5.2), P 0.001], ASES score [(35.2±9.6), (88.5±4.9), P 0.001], Rowe's score [(28.1± 6.6), (90.4±2.7), P 0.001] were significantly improved at the latest follow-up. The radiographs showed that the anchor was not loosened, the fracture fragment healed well, and the rotator cuff regain proper continuity. [Conclusion] The one-stage arthroscopic anchor fixation of bony Bankart injury and rotator cuff tear is reliable technique, achieves satisfactory medium-term clinical consequence.
