Purpose: The purpose of this article was to review the effectiveness of arthroscopic debridement and tuberoplasty, and to evaluate the clinical and radiologic results of our series for irreparable massive rotator cuff tears in the elderly. Materials and Methods: We reviewed articles that focused on the treatment options and decision making for irreparable massive rotator cuff tears. In particular, we summarized the reported results of arthroscopic debridement and tuberoplasty for irreparable massive rotator cuff tears in the elderly. Among consecutive patients who had arthroscopic tuberoplasty for irreparable massive rotator cuff tears in our series, thirty-two patients available for clinical and radiological evaluation at a mean follow-up of 29 months (range, 13-52 months) were enrolled and reviewed for the analysis. Results: At the last follow-up, the range of active forward flexion increased significantly with excellent pain relief and improvement in the ability to perform the activities of daily living. However, the group with less than 2 mm in preoperative acromiohumeral distance showed inferior postoperative results. Conclusion: Arthroscopic tuberoplasty may be an alternative option in irreparable massive rotator cuff tears for pain relief and improvement of range of motion. However, good results can not be expected if the acromiohumeral distance is less than 2 mm preoperatively and decreases postoperatively, or when the preoperative range of motion is less than $90^{\circ}$ on flexion and abduction.

Background: This study was performed to identify the incidence of screw in-type lateral anchor pull-out in patients older than 60 years who underwent rotator cuff repair for large to massive rotator cuff tear (RCT). Methods: We reviewed 25 patients over 60 who were diagnosed with large to massive RCT and underwent arthroscopic rotator cuff repair in our hospital from March 2017 to February 2021. Preoperative tear size (anterior to posterior, medial to lateral) was measured via preoperative magnetic resonance imaging (MRI). All 25 patients underwent MRI scanning on postoperative day 1 and at 3 months after surgery. The change of anchor position was measured in axial views on MRI images postoperative day 1 and 3 months after surgery. And it was statistically compared according to bone mineral density (BMD), sex, and number of lateral anchors. Results: Two MRIs (postoperative day 1 and 3 months) in 25 patients were compared. Anchor pull-out occurred in six patients during 3 months (6.7%), and the mean pull-out length difference was 1.56 mm (range, 0.16-2.58 mm). There was no significant difference in the number of pull-out anchors, degree of pull-out difference by comparing BMD (A, BMD≤-2.5; B, BMD>-2.5), sex, or number of anchors used in each surgery (C, two anchors; D, three anchors) (p>0.05). Conclusions: Pull-out of screw in-type anchors was rarely observed and the mean pull-out length difference was negligibly small in our study. The screw in-type lateral anchor seems to be a decent option without concern of anchor pull-out even in elderly patients.

Purpose: This study evaluated clinical results, and recommended treatment protocol of traumatic anterior shoulder dislocation in the patients older than 60 years of age. Materials and Methods: Thirty-eight patients with first traumatic anterior shoulder dislocation aged over 60 years were included. The average age was 69.4 (range, 60 to 87 years). There were 8 men (average age of 71.6) and 30 women (average age of 69). Most common cause of injuries was a fall on the outstretched hand. The additional injuries were evaluated using MRI or CT arthrogram in the patients with significant pain and weakness while movements after 2 weeks sling immobilization. Results: Fifteen patients (39%) had rotator cuff tears and 5 patients (14%) had greater tuberosity fractures. The sizes of rotator cuff tears were diverse; 2 partial tears, 1 small tear, 4 medium tears, 3 large tears and 5 massive tears. Among 5 massive cuff tears, 3 patients revealed cuff arthropathy after reduction. 4 patients (11%) had recurrent dislocation more than one time during 1 month after the first dislocation. Bankart lesions revealed in 5 patients and three of them had associated rotator cuff tears. 3 out of 5 patients with Bankart lesions, 13 out of 15 patients with rotator cuff tears and 3 patients with displaced greater tuberosity fracture had operations. Conclusion: The injury mechanism of shoulder dislocation in patients older than 60 years of age seems to have either anterior or posterior mechanism. The diagnosis and treatment should be approached 2 weeks after dislocation.

Purpose: Irreparable massive rotator cuff tears pose a distinct clinical challenge for the orthopaedist and non-surgical treatment has had inconsistent results and proven unsuccessful for chronic symptoms, while surgery, including debridement and partial and complete repairs have had varying degrees of success. Materials and Methods: For rotator cuff tears that are deemed irreparable, treatment options are limited. Results and Conclusion: The use of tendon transfers (latissimus dorsi for posterosuperior type cuff defects and pectoralis major for subscapularis defects) in younger patients to reconstruct rotator cuffs and re-establish function and restore shoulder kinematics can be useful in solving this difficult problem.

Purpose: The findings of preoperative magnetic resonance imaging (MRI) and ultrasonography (US) examination in the diagnosis of rotator cuff tear were then compared with the findings of arthroscopic examination, and to evaluate the postoperative integrity of rotator cuff using serial US examination. Methods: Between February and May 2008, 29 patients with rotator cuff tear had undergone preoperative US and MRI examination and subsequent arthroscopic examination. And the results of MRI and US were compared with intra-operative results of the arthroscopic examination. We observed the postoperative integrity of rotator cuff using serial (postoperative 2 weeks, 6 weeks, 3 months) US examination. Results: The sensitivity of US and MRI for identifying rotator cuff tear were 100% and 100%. The sensitivity of US and MRI were 95% and 82% in full thickness tear, and 50%, 33% in partial thickness tear, respectively. Overall accuracy of US and MRI were 86%, 69%. Among 22 patients were operated for full thickness tear, intra-operative gap formation was identified in 11 patients (50%, small to medium 2 cases, large to massive 9 cases) which were identified at 2 weeks postoperative US. We could find 5 re-tears (23%, small to medium 1 case, large to massive 4 cases) on 6 weeks postoperative US after passive range of motion (ROM) exercise, and could also find 7 re-tears (32%, small to medium 2 cases, large to massive 5 cases)on 3 months postoperative US after active ROM exercise. Conclusion: Serial US after arthroscopic rotator cuff repair was useful to differentiate intra-operative gap formation from postoperative re-tear. We found 5 retears (23%) at 6 weeks and 7 retears (32%) at 3 months postoperative US, it was useful to make treatment plan during postoperative rehabilitation.

Background: Clinical outcomes and prognosis of large and massive rotator cuff tears are known to be unpredictable not only in degeneration of the rotator cuff, but also due to a high rate of retear. Methods: Totally, 81 patients who had undergone arthroscopic rotator cuff repair from May 2008 to February 2016 were evaluated in our study. Clinical and functional evaluations were performed with the Constant score and the University of California, Los Angeles (UCLA) score, as well as full physical examination of the shoulder. All patients were confirmed to have magnetic resonance imaging (MRI) of tendon healing at least 1 year postoperatively. Results: The average age at the time of surgery was 65 years (range, 47-78 years). The average duration of postoperative time in which a follow-up MRI was performed was 36.1 months (range, 12-110 months). Large tears were present in 48 cases (59.3%) and massive tears in 33 cases (40.7%). Overall, there were 33 retear cases (40.7%). All the average clinical outcome scores were significantly improved at the last follow-up (p<0.001), although repair integrity was not maintained. Compared to type A, types C, and D of the Collin's classification showed significantly higher retear rates (p=0.036). Conclusions: Arthroscopic rotator cuff repair yields improved clinical outcomes and a relatively high degree of patient satisfaction, despite the repair integrity not being maintained. Involvement of the subscapularis muscle or infraspinatus muscle had no effect on the retear rate.
