[Arthroscopic repair of Bankart lesion with bioabsorbable suture anchors]

Objective: To evaluate early clinical effects of bioabsorbable suture anchors for the treatment of Bankart lesion.

Methods: Total 23 patients with the Bankart lesion were treated with arthroscopic repair using bioabsorbable suture anchors from January 2010 to June 2017. There were 20 males and 3 females, with an average age of (23.4±3.9) years old (ranged, 19 to 34 years old). Fourteen patients had injuries on the right shoulder joint and 9 patients had the injuries on the left side. The mechanism of primary dislocation included 17 cases of training, 5 cases of sports injury and 1 case of falling down. The mean interval time from injury to surgery was(10.9±5.8) months (ranged, 3 to 36 months). The Bankart lesion was repaired by bio-cortical suture anchors. The Rowes rating system for Bankart repair was used to evaluate therapeutic effects.

Results: All 23 patients were followed up, with a mean duration of(24.5±3.7) months(ranged, 18 to 39 months). At the latest follow up, there was no recurrent dislocation occurred, and all patients had returned to sports and work. The Rowes rating system for Bankart repair was 53.91±11.67 pre-operationally and 91.74±12.30 post operationally, respectively (P<0.01). According to the Rowes rating system, there were 0 case of excellent, 0 case of fine, 9 cases of good and 14 cases of bad pre-operationally;16 cases of excellent, 4 case of fine, 3 cases of good and 0 cases of bad post operationally;the difference was statistically significant (P<0.01).

Conclusion: Applying bio-cortical bone suture anchors for the Bankart lesion is a reliable, efficient and cost effective treatment, which is also suitable for the revision of the Bankart lesion.
