Purpose: To study the clinical and radiologic results with arthroscopic Bankart repair using knotless metal suture anchor. Materials and Methods: From February 2001 to January 2005, 68 patients, who underwent arthroscopic Bankart repair using knotless suture anchor and were followed up more than 12 months, were evaluated. A mean follow-up period was 34 months. All shoulders were evaluated by Rowe scoring system, range of motion of the shoulder, pain degree of VAS, and This was compared by radiologic findings after surgery. Results: The Rowe scoring system was 43.30 preoperatively, which improved to 95.55 postoperatively. At last follow-up, there was no significance difference between operated shoulder and non-operated shoulder in range of motion. The degree of VAS was measured from 3.3 preoperatively to 0.5 postoperatively. The radiolucent line was shown around suture anchor in 15 shoulders. 2 shoulders of 15 shoulders were reoperated due to redislocation and anchor arthropathy. In Odds ratio, this group (15 patients) had more 2.6 times the subjective instability than other group (53 patients). Conclusion: Arthroscopic Bankart repair using knotless anchor suture is very effective operative technique. But we have to be careful because the radiolucent line around anchor showed up during a follow -up period may indicate poor prognosis.

Purpose: This study reported the outcomes following the use of bioabsorbable knotless anchor in patients with anterior instability of shoulder. Methods: We studied fifteen cases with traumatic anterior shoulder instability underwent arthroscopic Bankart repair with bioabsorbable knotless suture anchor between January 2003 and June 2003. Among fifteen patients, fourteen were male and one was female, with a mean patient age of 24 years (range 16-42). The mean follow-up was 14 months (range 12-18 months). We compared with operation time of twenty cases of arthroscopic Bankart repair by the suture anchor technique between January 2002 and October 2002. Results: Neither recurrent dislocation nor subluxation was happened in postoperative follow-up. Mean score for functional evaluation by Rowe et al. was 89.4 and that for patient subjective satisfaction was 87,5. At last follow-up period, average shoulder range of motion for flexion and external rotation was 171$^{\circ}$ and 54$^{\circ}$ respectively. All patients were satisfied except three who had an apprehension at the follow up. During Bankart repair, it took an average of 25.5 minutes for one knot with the use of suture anchor technique whereas an average of 16.5 minutes for one knot with the use of bioabsorbable knotless anchor. Significantly, we saved operation time with the use of bioabsorbable knotless anchor (P<0.05).Conclusion: Repairing the Bankart lesion with the use of knotless anchor technique has the advantage of obtaining good capsular tensioning and saving operation time. And it is considered to be very successful in treating shoulder instability without recurrent dislocation or subluxation.

Purpose: The purpose of this study was to evaluate the results of bioabsorbable knotless suture anchoring for isolated type II SLAP. Materials and Methods: Fourteen patients with isolated type II SLAP underwent a surgical repair with bioabsorbable knotless anchor arthroscopically. Instability, rotator cuff tears or simple subacromial decompression were excluded. The UCLA and pain of VAS (Visual Analogue Scale), ADL (Activity of Daily Living, from the American Shoulder and Elbow Society) were evaluated and patients underwent a thorough shoulder examination at a minimum follow-up period of 2 years postoperatively. Results: At a mean of 27.1 months follow-up. The mean UCLA score improved from 14.4 pre-operatively to 31.2 on last follow-up. The mean VAS for pain was 4.9 and on last follow-up 1.0. The mean VAS for instability was 2.6 and on last follow-up 0.5. The mean ADL was 10.4 and on last follow-up 25.0. 12 patients reported their satisfaction as good to excellent and 10 of the 14 patients returned to their pre-injury level of activity (athletics) (P<0.05). Conclusion: Arthroscopic repair with bioabsorbable knotless suture anchors is an effective surgical technique for the treatment of an isolated unstable type II SLAP lesion. Overall satisfaction was only 85.7%. 1 patient had severe stiffness and 1 patient had shoulder pain.
