[Objective] To introduce the surgical technique and preliminary clinical outcomes of "Chinese knot" for arthroscopic repair of supraspinatus tear in muscle-tendon junction. [Methods] Form February 2020 to January 2021, 14 patients underwent arthroscopic re- pair of supraspinatus tear in muscle-tendon junction with this Chinese knot technique. The Ethibond sutures were placed in the proximal end of the torn rotator cuff in a reverse triangle shape, like a "Chinese knot" in appearance, and then an anchor was inserted on the outside row, tied under the appropriate tension to repair the rupture. The side-side sutures were added to strengthen the rotator cuff repair if neces- sary. [Results] All the 14 patients were successfully operated on without serious complications, with operation time of (92.23±15.34) min. and were followed up for (7.22±1.85) months on average. The UCLA score, Constant score and range of motion of shoulder significantly in- creased (P＜0.05) , while VAS score significantly decreased over time (P＜0.05) . The MRI checks in regular revealed rotator cuff tissue heal- ing about 9 months after operation. [Conclusion] This “Chinese knot" technique for arthroscopic repair of supraspinatus tear in muscletendon junction is feasible, and achieves reliable clinical outcomes.
