[Arthroscopic repair of Bankart lesion with bioabsorbable suture anchors]

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

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.

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).

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.
