Purpose : We evaluated clinical result of arthroscopic and open Bankart repair in anterior shoulder instability to identify factors iuluencing operative result and prognosis. Materials & Methods . We reviewed 24 patients of anterior shoulder instability treated with arthroscopic Bankart repair in 16 cases and open Bankart repair in 8 cases. Average age was 26 years old and involved in dominant arm in 15 cases. Patients were suffered instability for 3.1 years before operation and mean follow-up was 2 year 9 months ( 1 you 9 months -4year 10 months). Results : Post operative pain was subsided in 2 weeks in arthroscopic surgery and 3 weeks in open surgery. The final range of motion after arthroscopic repair were flekion in 168" , external rotation in 54" , and internal rotation in 79, and after open repair 168" ,49" , and 78 respectively. In arthroscopic surgery,2 cases (13%) were redislocated, and 4 cases(25%) showed mild instability. In open case,1 case (11%) showed mild instability. According to function- al result by Rowe grading scale, satisfactory results were 12case (76%) in arthroscopic repair and 7 cases (88%) in open cases. Conclusions Both arthroscopic or open Bankart could get good results in the treatment of anterior instability of shoulder. In arthroscopic repair, perioperative morbidity was lower than open repair, but it needs careful rehabilitation program to prevent redislocation and to return to sports activity.

Purpose: The purpose was to identify the effectiveness of beach-chair position in the arthroscopic Bankart repair over conventional lateral decubitus position with distal traction. Materials & Methods: 36 arthroscopic Bankart repair through July 2000 to July 2001 was done under beach chair position. All cases were shoulder instability. Male patients were 6 and female were 4 with average age of 25 years. Arthroscopic suture anchor was used in 24 cases and average number was 3. Results: Interscalene block was tried in 29 patients and 1 case was changed to general anesthesia. Arthroscopic examination to identify Bankart lesion and associated pathology was done without difficulty Bankart lesions were easily reduced to anatomic position and placed suture anchor and hooking approprately. After the arthroscopic examination,3 cases were converted to open procedure without any positional change. Conclusion: Under interscalene block, the preparation was more simple and the patient could watch arthroscopic procedure with confidence. There was no hindrance in arthroscopic examination and arthroscopic repair could be dont: in more anatomic position. It can be easily changed to open repair if it needed

Purpose : The purpose of this study was to compare patients with anterior shoulder instability who were treated with an open Bankart procedure with those treated with an arthroscopic procedure, and to evaluate factors influencing the final outcomes and recurrence. Materials & Methods : One hundred seven shoulders underwent open Bankart repair, and fifty-one shoulders were treated arthroscopically. Average followup for open group was 34 months, and for arthroscopy group was 25 months. The Bankart Rating System by Rowe was used to evaluate the clinical outcome of the procedure. And, the patients were asked about any changes concerning their sports and professional activities. Results: According to Bankart Rating system by Rowe, open group had 97% fair to excellent results with 2 recurrent dislocation(1.8%) and 4 recurrent subluxation(3.6%), and arthroscopy group had 94% fair to excellent results with 3 recurrent dislocation(5.8%) and 4 recurrent subluxation(8%). In open group, 9 shoulders(8.4%) had the mild limitation of range of motion at the time of followup, and 2 shoulders(3.9%) in arthroscopy group. Age and gender do not seem to be a significant factor contributing to an increased re-recurrence rate. The incidence of re-recurrence seems to be affected by dominance, frequency, and patient's activity. The size of Bank art lesion might be also considered as a contributing factor. Conclusion: Either open or arthroscopic Bankart procedures are safe and effective methods with acceptable results if an adequate patient's selection, precise surgical technique and proper postoperative care are done. And arthroscopic surgery could be considered if the anterior instability is non-dominant, non-athlete, traumatic unidirectional and Bankart lesion has minimal erosion of the glenoid and it has thick and mobile labrum.

The results of open capsular shift(Group 1) and arthroscopic trans glenoid Bankart repair(Group 2) for the recurrent anterior dislocation of the shoulder were compared. During a 4-year period, 25 patients were surgically treated. Fourteen shoulders had open Bankart procedure and capsular shift, and II shoulders were treated arthroscopically. A Bankart lesion was found in 12 out of 14 patients in Group I and all 11 patients in Group 2. Average follow-up period was 46 months for Group 1 and 23.4 months for Group 2. Group 1 showed 71.4% good to excellent results with 1 recurrent dislocation. Group 2 showed 90.9% good to excellent results with no recurrent dislocation. The cause of less favorable results of Group I compared with Group 2 was loss of external rotation postoperatively. The study showed that the results of arthroscopic Bankart repair was comparable to the open capsular shift in terms of stability, and the postoperative function was better than open capsular shift.

Purpose: We compared the results of open and arthroscopic Bankart repair in traumatic recurrent anterior dislocation ,3f the shoulder. Materials and methods: We analysed 7 cases underwent open Bankart repair (group I) and 13 cases underwent arthroscopic Bankart repair (group Ⅱ). The average follow-up period was 68.1 months (51-113 months) in group I and 41.1 months (16~57 months) in group Ⅱ. All patients in group I and Ⅱ were non-athletes. We analyzed statistically objective evaluation, such as the stability of shoulder joint, the range of motion, pain, impaired throwing, Bankart rating system by Rowe and subjective evaluation, visual analog scale (VAS) between two groups. Results: In terms of dominant and non-dominant shoulders, the age at initial episode of dislocation, the elapsed time from injury to surgery, the number of preoperative dislocations associated with susceptibility to apprehension. respectively, there was no statistically significant differences between two groups. In group I the average Rowe's scortls was 84.3 and 3 cases (43%) had excellent results,4 cases (S7cfo), good ones. In group H the average Rowe's scores was 87.3 and 7 cases (54%) had excellent results,6 cases, good ones. There was tendency to show more excellent results in group ll, but there was no statistically significant differences. The average VAS were 90.3 points in group I and 88 points in group Ⅱ, which showed also no statistically significant differences. Conclusion: Open and arthroscopic Bankart repairs had no significant difference and showed also good results in travinatic recurrent anterior dislocation of shoulder.

Eighty-nine shoulders in eighty-eight patients with traumatic unilateral anterior shoulder instability were evaluated for Rowe and UCLA scores, recurrence, return to activity, and range of motion by an independent examiner at an average of 39 months after either arthroscopic or open Bankart repair using suture anchors. The arthroscopic technique included a minimum of 3 anchors, and a routine incorporation of capsular plication and proximal shift. Twenty­six shoulders(86.6%) out of thirty in the open Bankart repair group had excellent or good results while fifty­four(91.5%) of the fifty-nine shoulders with arthroscopic Bankart repair had excellent or good results. The arthroscopic group revealed significantly better results in the Rowe(p=.041) and UCLA scores(p=.026). Two shoulders in each group developed redislocation. There were no significant differences in the loss of external rotation and return to prior activity between the two groups(p>.05). The residual instability occurred more frequently in the group of patients with lesser anchors. Arthroscopic suture anchor capsulorraphy has results equal to or better than the open Bankart procedure.

Purpose: To compare the results of open and arthroscopic method in recurrent anterior should erinstability. Materials and Methods: The 68 patients who have been taken the open or arthroscopic Bankartrepair for the period of Jan. 1995 to April. 2000. One group (23 patients) had elected an arthroscopic Bankart repair, the other group (45 patients) had chosen open stabilization. Patients were followed up12 to 63 months (ave. 34 months) after surgery. Results: We found 2 cases of subluxation out of open repair group, and then treated by conservative method. There were another 2 cases of dislocation and 2 cases of subluxation out of arthroscopicrepair group, and we have taken out 1 case of reoperation by open method. Using the functional scales by Rowe, the patients who have taken the open method posted at the average point of 87, while the arthroscopic method posted 85 points. Patients satisfaction points were 84.6 and 72.5 respectively. There were no criteria of statistically significant except stability and motion score. Conclusion: Open Bankart repair would be better in stability, and arthroscopic method in ROM gain. Proper patient selection based on physical examination and arthroscopic inspection to optimize the indications contributed to successful treatment.
