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.

Background: This study is performed to evaluate anchor-related outcomes and complications after arthroscopic rotator cuff repair using 30% ${\beta}$-tricalcium phosphate (${\beta}$-TCP) with 70% poly lactic-co-glycolic acid (PLGA) biocomposite suture anchors. Methods: A total of 78 patients (mean age, $61.3{\pm}6.9years$) who underwent arthroscopic medium-to-large full-thickness rotator cuff tear repair were enrolled. The technique employed 30% ${\beta}$-TCP with 70% PLGA biocomposite suture anchors at the medial row (38 patients, Healix $BR^{TM}$ anchor [Healix group]; 40 patients, Fixone anchor B [Fixone group]). The radiologic outcomes (including perianchor cyst formation or bone substitution) and anatomical outcomes of the healing failure rate were evaluated using magnetic resonance imaging at least 6 months after surgery, the pain visual analogue scale at 3, 6 months, and final follow-up visit, and American Shoulder and Elbow Surgeons scores at least 1 year postoperatively. Anchor-related complications were also evaluated. Results: The perianchor cyst formation incidence was similar for both groups (60.5%, Healix group; 60.0%, Fixone group; p=0.967), although severe perianchor cyst incidence was slightly lower in the Fixone group (15.0%) than in the Healix group (21.1%). There was no occurrence of anchor absorption and bone substitution. No differences were observed in the healing failure rate (13.2%, Healix group; 15.0%, Fixone group; p=0.815) and functional outcome between groups (all p>0.05). Anchor breakage occurred in 5 patients (2 Healix anchors and 3 Fixone anchors); however, there were no major anchor-related complications in either group. Conclusions: No differences were observed in the clinical outcomes of the Healix and Fixone groups, neither were there any accompanying major anchor-related complications.

One of the most important factors leading to a successful healing of rotator cuff tear is good bone quality to secure the suture anchor in the bone for a stable fixation. However, rotator cuff tear are commonly found in elderly patients, and their proximal humerus often shows osteoporosis or cystic lesions. Especially when the transosseous repair prevails for a torn rotator cuff, a weak metaphyseal cancellous bone is often the case, which associated with difficulty in stable fixation of the lateral row suture anchor. In this situation, we were able to augment the lateral row fixation with polymethylmethacrylate bone cement. Although there is a concern of disturbance in the blood flow and healing potential, our case showed good clinical results with respect to healing. If we suspect a weak fixation of the lateral row suture anchor, bone cement seems to be a good option for augmentation.

Purpose: This study examined the outcomes of closed reduction and fixation of the coracoid process fracture using a suture anchor in a patient with combined acromioclavicular dislocation for which the coraco-clavicular ligament was intact. Materials and Methods: A 26 year-old male patient with a coracoid process fracture that was associated with a type III acromioclavicular joint dislocation was operated on with anchor suture fixation. This is the first trial of this operative procedure. Results: At the postoperative follow-up at 3 months, complete union of the coracoid process fracture was seen. The shoulder had a full range of motion and the shoulder function was normal. Conclusion: Closed reduction and fixation using one suture anchor for treating coracoid process fracture is a safe, effective procedure.

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.

Background: We investigated the risk factors for the recurrence of anterior shoulder instability after arthroscopic surgery with suture anchors and the clinical outcomes after reoperation. Methods: A total of 281 patients (February 2001 to December 2012) were enrolled into our study, and postoperative subluxation and dislocation were considered as recurrence of the condition. We analyzed radiologic results and functional outcome including the American Shoulder and Elbow Surgeons Evaluation Form, the Korean Shoulder Society Score, and the Rowe scores. Results: Of the 281 patients, instability recurred in 51 patients (18.1%). Sixteen out of 51 patients (31.4%) received a reoperation. In terms of the functional outcome, we found that the intact group, comprising patients without recurrence, had a significantly better functional outcome than those in the recurrent group. The size of glenoid defect at the time of initial surgery significantly differed between intact and recurrent group (p<0.05). We found that the number of dislocations, the time from the initial presentation of symptoms to surgery, and the number of anchor points significantly differed between initial operation and revision group (p<0.05). The functional outcome after revision surgery was comparable to intact group after initial operation. Conclusions: Eighteen percent of recurrence occurred after arthroscopic instability surgery, and 5.6% received reoperation surgery. Risk factors for recurrence was the initial size of glenoid defect. In cases of revision surgery, good clinical outcomes could be achieved using additional suture anchor.

Purpose: This study presents 5 patients who had metallic anchor protrusion on glenoid after Bankart repair in anterior shoulder instability and reviewed the cause, clinical feature and arthroscopic removal technique. Method and Materials: 5 male with average age of 22 years (range 19 to 25 years) were included. 4 patients had arthroscopic Bankart repair and 1 patient had open repair for anterior shoulder instability. They had protruded metallic suture anchors on glenoid and the protruded suture anchors were removed arthroscopically using larger suture anchor empty inserter. Results: 4 patients had painful clicking sound with motion of abduction and external rotation and 1 patient showed shoulder instability. The ROM showed normal except mild degrees loss of external rotation. The position of protruded metallic anchor was 2, 3 and 5 O'clock in three patients and 4 O'clock in 2 patients. In 2 patients, the metallic suture anchor was malpositioned about 5mm off on the medial side from the anterior glenoid edge. All had Outerbrige classification Grade II-III chondral damage on humeral head and 1 patient showed glenoid cartilage destruction. None had shoulder instability after 2 years of follow-up. Constant score was 65 preoperatively and 89 postoperatively. ASES score was 67 preoperatively and 88 postoperatively. Conclusion: Symptoms of protruded suture anchor are not combined with instability. Most of symptoms were revealed from the rehabilitation period and confused with postoperative pain. Prompt diagnosis and early arthroscopic removal or impaction of protruded metallic suture anchor is recommended because of serious glenohumeral cartilage destruction. This is easy and simple and reproducible method to remove protruded metallic suture anchor arthroscopically.
