[Modified arthroscopic anterior approach for the treatment of shoulder Bankart lesion]

To explore the effects of single anterior approach under shoulder arthroscopy in the treatment of Bankart injury, and to provide a scheme to overcome the difficulties and simplify the operation process.

From July 2016 to January 2019, 62 patients with recurrent dislocation caused by Bankart leision were treated under shoulder arthroscopy, including 50 males and 12 females, ranging in age from 19 to 44 years old with an average age of (26.5±6.1) years old. There were 25 cases of left shoulder and 37 cases of right shoulder. The patients were divided into two groups according to the operation mode, 35 patients in the front modified single approach group (experimental group) and 27 patients in the traditional double approachgroup (control group). The results of the operation were evaluated by assessing the preoperative and postoperative ASES scores of the shoulder joint, and the time of the approach establishment and the overall operation process was recorded to evaluate whether the operation time of the experimental group was shortened.

Three patients were lost during the follow-up after operation, and except for one case of re-dislocation, all patients achieved satisfactory results without neurovascular injury and other complications. The patients were followed up before operation and 3, 6, 12 months after operation, and the ASES scores were significantly enhanced at the latest follow-up compared with those of before operation. The time of establishing surgical approach in the experimental group was (7.5±1.5) minutes, which was shorter than that of control group (13.7±1.2) minutes.

The improved technique of single-channel anterior approach has the advantages of reducing the surgical incision and shortening the operationtime while ensuring the quality of the operation, which is worthy of popularization and application.
