For a bursal-side retracted laminated rotator cuff tear, simple repair of the retracted bursal-side rotator cuff might be insufficient because the repaired tendon could remain as an intratendinous tear of the rotator cuff. We present a repair method for intratendinous rotator cuff tears using the suture-bridge technique. We believe that this method helps to preserve the remnant rotator cuff tendon without tissue damage and restores the normal rotator cuff footprint in bursal-side delaminated rotator cuff tears.

Object: To evaluate the efficiencies of the arthroscopic rotator cuff surgery which is Performed without the traction system in the lateral decubitus position. Methods: Twenty-nine cases of the arthroscopic rotator cuff surgery performed without the traction system in the lateral decubitus position were studied from February, 2002 to January, 2005. We performed a repair using the arthroscopic debridement and the arthroscopic rotator cuff repair, or using the mini-open incision technique after the confirmation of rotator cuff tear, then, the arthroscopic subacromial decompression was performed after the confirmation of subacromial lesions Results: We could easily find the subscapularis tear which was often overlooked in the arthroscopic rotator cuff surgery performed with the traction surgery by the relaxation of the subscapularis, as the arm position was internally rotate about 45 to 70 degrees from abducted position. We found that the operation time was reduced 14 minutes shorter than the operation time of the controlled group which had the surgery with the traction system on the average. We also found that there were no neurovascular complications from all cases. Conclusions: The arthroscopic rotator cuff surgery without traction system in the lateral decubitus position provided the better visual field, easy manipulation of the joint and reducing operation time.

Background: Since the establishment of biological augmentation to improve the treatment of rotator cuff tears, it is imperative to explore newer techniques to reduce the retear rate and improve long-term shoulder function after rotator cuff repair. This study was undertaken to determine the consequences of a gel-type atelocollagen injection during arthroscopic rotator cuff repair on clinical outcomes, and evaluate its effect on structural integrity. Methods: Between January 2014 and June 2015, 121 patients with full thickness rotator cuff tears underwent arthroscopic rotator cuff repair. Of these, 61 patients were subjected to arthroscopic rotator cuff repair in combination with an atelocollagen injection (group I), and 60 patients underwent arthroscopic rotator cuff repair alone (group II). The visual analogue scale (VAS) for pain and the Korean Shoulder Society (KSS) scores were evaluated preoperatively and postoperatively. Magnetic resonance imaging (MRI) was performed at 6 months postoperatively, to assess the integrity of the repair. Results: VAS scores were significantly lower in group I than in group II at 3, 7, and 14 days after surgery. KSS scores showed no significant difference between groups in the 24 months period of follow-up. No significant difference was obtained in the healing rate of the rotator cuff tear at 6 months postoperatively (p=0.529). Conclusions: Although a gel-type atelocollagen injection results in reduced pain in patients at 2 weeks after surgery, our study does not substantiate the administration of atelocollagen during rotator cuff repair to improve the clinical outcomes and healing of the rotator cuff.

Retear patterns after arthroscopic rotator cuff repair are classified into two patterns according to retear location. Type 1 is when the retear pattern occurs directly on the tendon at the bone repair site using the suture anchor repair method. Type 2 is when the retear pattern occurs at the musculocutaneous junction with a healed footprint in patients who undergo the suture bridge method. Here, the authors report another retear pattern, which was identified as a type 2 retear on magnetic resonance imaging in patients who had undergone arthroscopic rotator cuff repair by the suture-bridge technique. This pattern was different from the type 2 retear and occurred at the portion of the cuff away from the healed rotator cuff under the view of the arthroscope.

Delaminated rotator cuff tear pertains to the horizontal split of the tendon substance. As reported previously, the presence of a delaminated tear and incidence of delaminated rotator cuff tear ranges from 38% to 92%. The different strain intensities applied across the rotator cuff tendon, and the shear stress between the bursal and articular layers seem to play a role in its pathogenesis. In a delaminated rotator cuff tear, the degree and direction of retraction between two layers differ, with accompanying intrasubstance cleavage. A surgeon therefore needs to consider and carefully evaluate the tear characteristics when repairing delaminated rotator cuff tear. Delaminated rotator cuff tear is considered to be a poor prognostic factor after rotator cuff repair, but numerous surgical repair techniques have been introduced and applied to resolve this problem. Recent literature has reported good clinical outcomes after delaminated rotator cuff repair.

Purpose : To compare and analyze the results of arthroscopic subacromial decompression and rotator cuff repair between partial rotator cuff tear and complete rotator cuff tear. Material and Methods : The authors studied 42 patients of rotator cuff tear with operation and followed over one year at Dankook university hospital from September, 1998 to March, 2001 The patient average age is 53 years and follow up period is 23 months (12-42mon1hs). We obtained 22 cases in the partial rotator cuff tear group and 20 cases in the complete rotator cuff tear group. In all cases, we used ASES methods to evaluated pain scale and function. Result : In the last follow up patients, the pain scale is decreased from 7.2 to 0.9 (ASES method : 34 to 91) in the partial rotator cuff tear group and from 7.6 to 1.2 (ASES method . 29 to 88) in the complete rotator cuff tear group, but there was no evidence of statistical difference between two groups (P>0.05). The range of motion after operation were increased in two groups. Excellent to good results were obtained 93％ and 95％ patients had pain relief and satisfied function. Conclusion : Arthroscopic subacromial decompression and arthroscopic rotator cuff repair showed good results for both of (ult-thickness and partial thickness rotator cuff tear patients in pain relief and improving the function.

Background: This study analyzed questions searched by rotator cuff patients and determined types and quality of websites providing information. Methods: Three strings related to rotator cuff repair were explored by Google Search. Result pages were collected under the "People also ask" function for frequent questions and associated webpages. Questions were categorized using Rothwell classification and topical subcategorization. Webpages were evaluated by Journal of the American Medical Association (JAMA) benchmark criteria for source quality. Results: One hundred twenty "People also ask" questions were collected with associated webpages. Using the Rothwell classification of questions, queries were organized into fact (41.7%), value (31.7%), and policy (26.7%). The most common webpage categories were academic (28.3%) and medical practice (27.5%). The most common question subcategories were timeline of recovery (21.7%), indications/management (21.7%), and pain (18.3%). Average JAMA score for all 120 webpages was 1.50. Journal articles had the highest average JAMA score (3.77), while commercial websites had the lowest JAMA score (0.91). The most commonly suggested question for rotator cuff repair/surgery was, "Is rotator cuff surgery worth having?," while the most commonly suggested question for rotator cuff repair pain was, "What happens if a rotator cuff is not repaired?" Conclusions: The most commonly asked questions pertaining to rotator cuff repair evaluate management options and relate to timeline of recovery and pain management. Most information is provided by medical practice, academic, and medical information websites, which have highly variable reliability. By understanding questions their patients search online, surgeons can tailor preoperative education to patient concerns and improve postoperative outcomes.

Iatrogenic damage of the rotator cuff followed by postoperative shoulder function loss is a potential complication after antegrade intramedullary nailing (AIN) for a humeral fracture. The authors present a case of arthroscopic rotator cuff repair and subacromial decompression of a non-healed rotator cuff tendon (mainly supraspinatus) and secondary impingement syndrome caused either by the tear or a proud nail after AIN for a mid-shaft humeral fracture. At presentation, the patient complained of right shoulder pain and 'snapping', especially during forward elevation and abduction of the shoulder, of 4 years duration. Right shoulder pain started sometime after pain due to the humeral shaft fracture, operation had subsided, and persisted after nail removal. Arthroscopic findings showed a longitudinal rotator cuff tear at the nail entry point that had not healed and severe fibrous hypertrophy on the acromion underspace, which is a unique finding since most longitudinal splits of tendon fibers are more likely to heal than conventional rotator cuff tears detached from bone. The torn rotator cuff was repaired after debridement and placing side-to-side sutures. At his 34-month follow-up after rotator cuff repair, the patient showed complete recovery and had excellent clinical scores.

In the patients of retracted massive rotator cuff tears, there are much of difficulty to functional recovery and pain relief. Nevertheless the development of treatment, there are still debates of the best treatments in the massive rotator cuff tears. Recenlty various of treatments are introduced; these are acromioplasty with debridement, biceps tenotomy, great tuberoplasty with biceps tenotomy, partial repair, mini-open rotator cuff repair, arthroscopic rotator cuff repair, soft tissue augmentation, tendon transfer, flap, hemiarthroplasty, and reverse total shoulder arthroplasty. That there is no difference of result for reverse total shoulder arthroplasty between patients who have massive rotator cuff tear without arthritis and patients who have cuff tear arthropathy. Reverse total shoulder arthroplasty is one of reliable and successful treatment options for massive rotator cuff tear. Especially it is more effective for patients who have a pseudoparalysis.

회전근 개 파열의 봉합술은 최근 들어 괄목할만한 발전을 보여주고 있다. 회전근 개 파열의 자연사를 관찰하면 대부분의 경우에서 시간이 지남에 따라 크기가 증가하는 양상이 관찰되었다. 회전근 개 파열의 후기에 오는 지방 침윤 및 광범위 회전근 개 파열 후 발생하는 회전근 개 파열 관절증은 회전근 개 파열의 봉합술에서 예후를 예측하거나 수술 시기를 결정하는데 중요한 요소라 할 수 있다. 회전근 개 파열시 증상 발생 후 3년 뒤에 중등도의 지방 침윤이 발생하는 것으로 관찰되어 그 이전에 회전근 개 파열의 봉합술을 시행하는 것이 추천되고 있으며, 또한 회전근 개 파열 관절증에서도 견봉상완골 간격이 감소하기 전에 봉합술을 하는 것이 권장되고 있다. 회전근 개 파열의 관절경하 봉합술은 크게 일열 봉합술 및 이열 봉합술로 나눌 수 있으며, 시간과 비용 면에서는 전자가 장점이 있으나, 생역학적이 관점에서는 후자가 더 우수하다. 이열 봉합술의 생역학적인 장점을 유지하면서 보다 적은 시간에 회전근 개의 봉합을 가능하게 한 교량형 봉합술이 개발되어 최근 널리 사용되고 있으며, 교량형 봉합술 내에서도 파열의 특성에 따라 몇 가지 다른 술식이 개발되어 사용되고 있다.
