Purpose: To evaluate the integrity of repair & technical tip in use of Massive Cuff Stitch at arthroscopic repair of rotator cuff tear. Materials and Methods: Twenthy-nine cases of arthroscopically repaired full thickness tear of rotator cuffs which are medium sized were evaluated. Between December 2004 to September 2005 we have studied, the average age 53($42{\sim}69$) years old, mean follow-up was 15($12{\sim}21$) months. We analyzed the results statistically by paired t-test. The integrity of repair were verified by follow up MRI which were checked 11 cases and ultrasound which were checked 10 cases. Results: VAS of pain improved preoperative average 7.1 to postoperative 0.9, ADL improved 11.2 to 25.6 respectively, UCLA improved 13.7 to 32.9(all, P<0.05). 89.7% showed excellent & good results at the final follow-up. The satisfied rate was 93.1%(27 cases). There was re-rupture of the repaired rotator cuff in one case out of 11 cases which were checked by MRI, and in one case out of 10 cases which were checked by ultrasound, and there was one case of thinning of cuff which were checked by ultrasound. Conclusion: The use of Massive Cuff Stitch in arthroscopic repair of rotator cuff tear have been reduced technical failure. It will be good surgical technique which maintain the integrity of repairs.

Purpose: To determine clinical results for arthroscopic repair of a full-thickness rotator cuff tear using a suture bridge technique. Materials and Methods: Between November, 2007 and October, 2008, we evaluated 90 cases of arthroscopic middle, large rotator tear cuff repair. The mean follow-up period was 15 months (range, 12-23 months). Forty-three cases had medium-sized tears; 47 cases had large-sized tears. At the preoperative stage and again at last follow-up, functional results were assessed by the KSS, ASES, UCLA and the PVAS (Pain visual analogue score). Results: Pain score improved from 2.56 preoperatively to 0.96 at final follow-up; movement scores improved from 6.94 to 1.70. At. final follow-up, the average UCLA score improved from 17.08 to 31.17 with 31 excellent (34%), 49 good (54%) and 10 poor results (12%). The final UCLA score was 31.47 in the group less than 60 years of age and 30.69 in the group over 61 years of age (p=0.344). The UCLA score was 31.23 in those with medium-sized tears and 31.11 in those with large-sized tears (p=0.924). The UCLA score was 31.10 in non-trauma patients and 31.23 in trauma patients (p=0.929). Conclusion: Arthroscopic repair of a full-thickness rotator cuff tear using a suture bridge technique can produce excellent clinical results. These outcomes are not affected by age or trauma history.

Purpose: To compare the results of a miniopen repair with those of complete arthroscopic repair in medium and large sized full thickness rotator cuff tears. Materials and Methods: The thirty four(34) patients with medium and large sized complete rotator cuff tear were observed, Group I (complete arthroscopic repair) were 13 cases and group II (miniopen repair) were 21 cases. The tear sizes are from 1cm to 5cm. The average follow up periods are 24(range;12$\~$36) and 28(range; 12$\~$36) months. Subjective pain was evaluated with VAS (visual analogue scale) in rest state. ADL (Activity of Daily Living) and UCLA scoring system were used to evaluate clinical results. Results: At last follow-up periods, pain and functional scores were improved but they had not been shown statistical significance (p>0.05). In the group I and group II, there are no significant difference in VAS, ADL; UCLA score, satisfaction (p>0.05). Conclusions: In medium and large sized full thickness rotator cuff tears, there are no significant clinical results between the arthroscopic and miniopen group.

Object : To evaluate the prognostic factors of the rotator cuff tear after anterior dislocation of the shoulder over the 5th decades of age. Methods : We evaluated twelve patients who had rotator cuff tears combined with primary anterior dislocation of the glenohumeral joint between May 1995 and October 1998. Their age were ranged from 42 to 67-years-old. Two of them were initially presumed to have an injury of the axillary nerve and associated with avulsion fracture of the greater tuberosity. Among twelve patients who had rotator cuff tears, 8 cases had massive, 3 cases had medium and one case had a small sized tear. Results : All the tears of the rotator cuff were repaired and the results were obtained by UCLA shoulder rating scale. Ten cases of them revealed more than good results except for 2 cases who had been unhappy triad of the shoulder injury. Conclusions : In the case of anterior dislocation of shoulder, it is necessary to check the injury of rotator cuff and axillary nerve in the middle age group. If these injuries are combined, proper rotator cuff repair and axillary nerve rehabilitation program would be asked for better results.

Purpose: To compare the clinical and radiological result of arthroscopic Mattress Locking suture repair to that of a Simple suture repair with small and medium-sized rotator cuff tears. Materials and Methods: Among 92 patients who were followed up after arthroscopic repair in patients with small and medium-sized rotator cuff tear from April 2007 to October 2010, 27 patients who took Arthroscopic Mattress Locking suture were set as group I and 65 patients who took Simple suture were set as Group II. The average age of patients were 58 years old and average follow-up period was 30 months. For analysis, VAS, ASES and KSS were used to analyze the range of joint movement and pain. And, for the image result, MRI performed after operation were evaluated. Results: The average VAS, KSS, UCLA score and ASES prior to surgery improved in the last follow-up (p<0.001), while was no difference in two groups (p>0.001). In MRI follow-up examination, the 2 cases (7.41%) of group 1 showed increased rupture lesions with improved symptoms. And the 12 cases (18.47%) of group 2 showed increased rupture lesions with improved symptoms. Retears in the group I were significant less than the group II (p<0.001). Conclusion: Comparing patients with small and medium-sized rotator cuff tear who took arthroscopic mattress locking suture repair to those who took simple suture repair after over one year follow up period, the clinical result showed no significant difference between two groups. However, Mattress Locking suture repair showed excellent radiological result compared to simple suture repair when comparing rerupture.

Purpose: To compare the outcome of patients who underwent rotator cuff repair using all-arthroscopic mini-open repair techniques. Materials and Methods: We retrospectively reviewed 44 patients who underwent either arthroscopic (group I) or mini-open (group II) rotator cuff repair. 23 patients underwent an arthroscopic repair and 21 patients had a mini-open repair. The mean age was 50.4 years in the arthroscopic group and 56.7 years in the mini-open group. The outcomes for the 2 groups were evaluated using ROM, VAS, ASES, UCLA scale. Statistical analysis was performed using correlations, T-test, Paired T-test. The mean follow-up period in the arthroscopic and mini-open groups were 24.1months and 26.1months, respectively. Results: The group I (arthroscopic group) had 2 small-sized tears, 10 medium sized tears, and 11 large sized tears (3~5 cm). The group II (mini-open group) had 1 small sized tears, 8 medium sized tears, and 12 large sized tears. The mean cuff tear size of the group I and Group II were 3.8 cm and 4.2 cm, respectively. At last follow-up periods, ROM and functional scores were improved. In the group I and group II, there were no significant difference in ROM, VAS, ASES, UCLA score. Conclusion: The size of the tear did not produce different results at arthroscopic repair group but larger tear size was associated with a worse outcome in mini-open group. There were no significant clinical results between the arthroscopic and mini-open group.

Background: The effects of far-infrared radiation (FIR) on the treatment of rotator cuff diseases remains unknown. We evaluated the safety and efficacy of FIR after arthroscopic rotator cuff repair with regard to postoperative pain and healing. Methods: This prospective randomized comparative study included 38 patients who underwent arthroscopic rotator cuff repair due to a medium-sized tear. Patients were randomly divided into the FIR or control group (n = 19 per group). In the FIR group, FIR with an FIR radiator started 1 week postoperatively for 30 minutes per session twice daily. It lasted until abduction brace weaning at 5 weeks postoperatively. We assessed pain using a pain visual analogue scale (pVAS) and measured the range of motion (ROM) of the shoulder at 5 weeks, and 3 and 6 months, postoperatively. The anatomical outcome was evaluated using magnetic resonance imaging at 6 months postoperatively. Results: At 5 weeks postoperatively, the average pVAS score was lower in the FIR group than in the control group (1.5 ± 0.8 vs. 2.7 ± 1.7; P = 0.019). At 3 months postoperatively, the average forward flexion was higher in the FIR group (151.6° ± 15.3° vs. 132.9° ± 27.8°; P = 0.045), but there was no significant difference at 6 months postoperatively. There was no significant difference in healing failure between the groups (P = 0.999). Conclusions: FIR after arthroscopic rotator cuff repair could be an effective and safe procedure to reduce postoperative pain, thereby facilitating rehabilitation and better ROM in the early postoperative period.

Background: Subscapularis tendon insertion at the first facet has separate layers (deep and superficial). The purpose of this study is to evaluate postoperative clinical outcomes and radiological healing according to each layer of detachment in the first facet involving subscapularis tendon tear. Methods: Eighty-three patients who underwent arthroscopic repair due to First facet involving the scapularis tendon tear accompanying small to medium sized posterosuperior cuff tear were classified into three groups (group A: deep layer partial detachment, group B: deep layer complete detachment, but no superficial layer detachment, and group C: deep layer and superficial layer complete detachment). Subscapularis tendon healing was evaluated using computed tomography arthrogram and clinical result was evaluated using American Shoulder and Elbow Surgeons (ASES) shoulder score, Constant score and University of California Los Angeles (UCLA) shoulder score. Results: Retear rate of the subscapularis tendon was 2.2%, 18.2%, and 33.3% in group A, group B, and group C, respectively. These rates showed statistically significant difference among the three groups, which were classified by deep and superficial layer detachment in the first facet (p=0.003). Group A showed significant difference in subscapularis tendon healing compared with group B and group C (p=0.018 and p<0.001, respectively), but there was no statistical difference between group B and group C (p=0.292). Regarding clinical outcomes, there was no significant difference among three groups in ASES and UCLA score at final follow-up (p=0.070 and p=0.106, respectively). Conclusions: Complete detachment of deep layer may be related with retear occurrence regardless with detachment of superficial layer, but clinical outcome may not be related with each layer detachment in the first facet involving subscapularis tendon tear.
