Purpose: In this prospective, randomized study, we compared the results of early motion versus conventional immobilization after the arthroscopic Bankart repair. Materilal and Methods : We performed an arthroscopic Bankart repair using suture anchors in 62 patients with traumatic anterior shoulder instability and randomized them into two groups; Group 1 (n=28; mean age, 28 years) underwent three-week of immobilization and conventional rehabilitation program, while Group 2 (n=34; mean age, 29 years) underwent an accelerated rehabilitation program with staged range of motion and strengthening exercises starting from the immediate postoperative day. Selected patients were non-athletes with a classic Bankart lesion and a robust labrum. Analysis of outcome included pain scores (6-week and follow-up: 31(9 months), range of motion, return to activity, recurrence, patients’ satisfaction with each program, and shoulder scores (ASES, UCLA, and Rowe). Results : The recurrent rate was not different between the two groups (2 anterior apprehension from each group) (p=0.842). Patients with accelerated rehabilitation resumed functional range-of-motion faster and returned earlier to the functional level of activity (p<0.05). Accelerated rehabilitation decreased postoperative pain and more patients were satisfied with this program (p<0.05). No differences were found between the two groups at the follow-up with regards to the shoulder scores, return to activity, pain score, and the range-of-motion. Conclusions : Early mobilization after arthroscopic Bankart repair does not increase the recurrence rate in selected patients. Although the final outcomes are similar in both groups, the accelerated rehabilitation program promotes functional recovery and reduces postoperative pain, which enables patients an early institution of desired activities.

Recurrence is the most common complication after shoulder instability surgery, and the main causes of the postoperative recurrence of instability are trauma, misdiagnosis, and technical errors. The risk factors of recurrence may be classified as patient related, anatomical or technical. Causes of failure should be thoroughly evaluated by meticulous history taking, physical examination, and imaging studies, and followed by proper treatment of pathologic lesions. Nonoperative treatment should be considered initially in cases of recurred instability after shoulder instability surgery, but if this fails, repeated recurrence is prevented by performing appropriate anatomical reconstruction of ruptured Bankart lesions, capsular laxities, glenoid deficiencies and humeral head bone defects.

Purpose: This study is to analyze the prevalence of various intra-articular lesions in patients with traumatic recurrent anterior dislocation of shoulder over 40 years and suggest clinical implications for treatment. Materials and Methods: We retrospectively studied 16 cases that underwent surgical treatment for recurrent anterior dislocation of shoulder from January 2001 to May 2009. There were 9 males and 7 females, and the mean age was 52.7years. We carried out arthroscopic exam for all patients based on standard protocol, which included labrum, capular lesion, cuff, bony lesions. Results: All 16 cases showed Hill-Sachs lesion, 3 patients (19%) had bony Bankart lesion, 6 patients (38%) had labral tear. Capsular tear were found 15 patients (94%). Twelve (75%) had ruptured supraspinatus and 5 (31%) had subscapularis tear. Only one (6%) had SLAP lesion. Conclusion: There was relatively higher incidence of capsular and rotator cuff tears in patients over age 40 years. Preoperative planning to address these lesions is highly recommended.

Purpose: The purpose of the present study was to evaluate the diagnostic efficacy of CT arthrography (CTA) in the assessment of various shoulder pathologies, compared with MR arthrography (MRA) and MRI with arthroscopic correlation. Materials and Methods: CTA in 84 patients, MRA in 70 patients, and MRI in 27 patients were obtained. A radiologist interpreted each image for 5 pathologies: Bankart, SLAP, Hill-Sachs lesion, full-thickness, and partial-thickness rotator cuff tear. Detailed arthroscopic reports were compared with CTA, MRA, and MRI. The sensitivity, specificity, predictive values, and accuracy were calculated. The agreement between each diagnostic modality and arthroscopy was calculated. Diagnostic efficacy was assessed by the areas under the receiver operating characteristic (ROC) curves. Results: The diagnostic values of all three imaging groups were comparable to each other for Bankart, SLAP, Hills-Sachs, and full-thickness cuff tear lesions, but those of CTA were lower than MRI and MRA for partial-thickness cuff tears. The areas under the ROC curves for CTA, MRA, and MRI were not significantly different for all pathologies, except for partial-thickness cuff tears. Conclusion: CTA was equally competent to MRA or MRI in demonstrating Bankart, Hill-Sachs lesions, SLAP, and full thickness rotator cuff tears but not as efficient in diagnosing partial thickness rotator cuff tears.

Purpose: The purpose of this study was to compare the clinical results of absorbable knot-tying and absorbable knotless suture anchors in arthroscopic Bankart repair. Materials and Methods: This study compared the patients who underwent arthroscopic Bankart repairs using absorbable knottying suture anchors (59 patients: KT Group), and absorbable knotless suture anchors (52 patients: KL Group). Preoperative and postoperative evaluations were performed by Rowe scores, patient satisfaction score, visual analogue scale (VAS), American shoulder and elbow surgeons (ASES) score, range of motion (ROM), and re-dislocation rate. Results: Postoperative VAS, Rowe scores, ASES score were significantly not different between the 2 groups (VAS: p=0.250, Rowe score: p=0.412, ASES: p=0.052). Mean postoperative VAS was 0.5 in KT Group and 0.8 in KL Group (p=0.250), and limited ROM was noted only in one patient in KL Group. Mean Rowe score was 94.3 in KT Group and 96.3 in KL Group (p=0.412), and mean ASES score was 97.3 in KT Group and 94.0 in KL Group (p=0.052). Re-dislocation rate were no different between the 2 groups. Conclusion: There were no differences in clinical outcomes and re-dislocation rate between Knot-Tying and Knotless repairs.

Purpose: The aim of this retrospective study were to report the short-term results of inferior capsular shift procedure using splitting subscapularis and capsule for the patients who had shoulder instability and were apt to recur after arthroscopic stabilization procedure. Materials & Methods : Fifteen cases of instability of the shoulder were included with an average follow-up of 2 years (range: 1$\~$3 years). There were 13 men and 2 women with an average age of 27years. Multidirectional instability was found in 4 cases, voluntary instability in 3 cases, bony Bankarte lesion in 2 cases and 6 cases were contact sportmen. Thirteen shoulders underwent the inferior capsular shifts and Bankart repairs and 2 shoulders without Bankart lesion underwent the inferior capsular shift only. Average 19 mm of shift (range: 10$\~$25 mm) was done. Results : Fourteen patients showed good and excellent results with one subluxation and one positive apprehension test. Postoperative ranges of motions did not change in forward elevation, external rotation at side and external rotation at 90$^{\circ}$ abduction (p>0.05). Conclusion : Inferior capsular shift procedure using splitting subscapularis and capsule can be helpful in shoulder instability patients who were high-risk group of recurrence with arthroscopic procedure.

Purpose: This study reports the clinical results of the arthroscopic repair of type V SLAP lesion with bio-knotless anchor. Materials and Methods: 10 cases of 10 patients (10 male) were included in this study. The average age was 32.7 years old and the period from the first injury to operation was average 47.2 months. Preoperative Rowe score was average 37.5. Arthroscopic SLAP repair with 1 or 2 bio-knotless anchors were performed and arthroscopic Bankart repair with bio-knotless anchors were performed in all cases; 3 anchors were used in 7 cases and 2 anchors in 3 cases. The average follow up period was 15.7 months. Results: The Rowe score improved to 93 at last follow up period and 8 cases had full range of motion of the shoulder. 2 case had mild limited range of motion of the shoulder (one case; 170 degrees in flexion, 60 degrees in external rotation and T12 level in internal rotation, the other case; 160 degrees in flexion, 45 degrees in external rotation and T12 level in internal rotation.) without any problem in normal activity. Conclusion: Arthroscopic repair with bio-knotless anchor in type V SLAP lesion is one of the good methods because of the good clinical results.

Purpose: To evaluate clinical features and surgical results for rotator cuff tear secondary to shoulder dislocation in middle-aged and elderly patients. Materials and Methods: We reviewed 19 patients over 50 years of age who had rotator cuff tears combined with shoulder dislocation between October 2004 and October 2008. There were 7 males and 12 females with a mean age 64.7 years (range, 50 to 78 years). The average follow-up duration was 22 months (range, 8 to 56 months). We investigated the number of dislocations, the size of the cuff tear, the presence of Bankart lesions and the time interval from dislocation to surgery. We also investigated the ASES score, UCLA score, SST score, and shoulder range of motion before and after surgery. We analyzed clinical outcomes and contributing factors. Results: ASES scores improved from 30.2 preoperatively to 72.3 postoperatively; UCLA scores improved from 12.9 to 26.5; SST scores improved from 2.4 to 7.3. Range of motion improved significantly: forward flexion, abduction, external rotation and internal rotation were, respectively, $110.8({\pm}39.3)^{\circ}$, $107.7({\pm}40)^{\circ}$, $22.5({\pm}17.6)^{\circ}$ and L5 level preoperatively; postoperatively they were $153.6({\pm}20.6)^{\circ}$, $152.1({\pm}20.8)^{\circ}$, $36.4({\pm}22.7)^{\circ}$ and L1 level. Age, the presence of Bankart lesions and the number of dislocations were not correlated with clinical outcomes. But the size of the cuff tear was correlated with clinical results. Also, the duration from dislocation to surgery was correlated with postoperative UCLA and SST scores (p=0.039, p=0.038). Conclusion: For shoulder dislocation, it is important to achieve early diagnoses of rotator cuff tears in middle-aged and elderly patients. If these injuries are both present, early rotator cuff repair should be performed for better clinical results.
