Compared to single row repair, use of lateral row anchors in suture bridge rotator cuff repair enhances repair strength and increases footprint contact area. If a lateral knotless anchor (push-in design) is inserted into osteoporotic bone, pull-out of the lateral row anchor can developed. However, failures of lateral row anchors have been reported at several months after surgery. In our cases, even though complete cuff healing occurred, delayed pull-out of the lateral row anchor in the suture bridge repair occurred. In comparison to a conventional medial anchor, further biomechanical evaluation of the pull-out force, design, and insertion angle of the lateral anchor is needed in future studies. We report three cases with delayed pull-out of lateral row anchor in suture bridge rotator cuff repair with a literature review.

One of the most important factors leading to a successful healing of rotator cuff tear is good bone quality to secure the suture anchor in the bone for a stable fixation. However, rotator cuff tear are commonly found in elderly patients, and their proximal humerus often shows osteoporosis or cystic lesions. Especially when the transosseous repair prevails for a torn rotator cuff, a weak metaphyseal cancellous bone is often the case, which associated with difficulty in stable fixation of the lateral row suture anchor. In this situation, we were able to augment the lateral row fixation with polymethylmethacrylate bone cement. Although there is a concern of disturbance in the blood flow and healing potential, our case showed good clinical results with respect to healing. If we suspect a weak fixation of the lateral row suture anchor, bone cement seems to be a good option for augmentation.

Background: The purpose of this study was to evaluate the postoperative magnetic resonance imaging (MRI) results of minimal-tying (one medial-row tie among 4 medial-row sutures) on the medial-row in double-row suture-bridge configuration ($2{\times}2$ anchor with $4{\times}4$ suture stands). Methods: From 2011 March to 2012 July, 79 patients underwent arthroscopic rotator cuff repair using $2{\times}2$ anchor double-row configuration. The mean age was 61.3 years (range, 31-81 years). Two double-loaded suture anchors were used for medial-row. Four medial-row stitches were made with only one medial-row knot-tying (the most anterior suture). Lateral-row was secured using the conventional suture-bridge anchor technique; all 4 strands were used for each anchor. Repair integrity was evaluated with MRI at mean 6.2 months postoperatively. Retear and the pattern of retear, change of fatty infiltration, and muscle atrophy of supraspinatus were evaluated using pre- and postoperative MRI. Results: Repaired tendon integrity was 38 for type I, 30 for type II, 6 for type III, 4 for type IV, and 1 for type V, according to Sugaya classification. Considering type IV/V as retear, the rate was 6.3% (5 out of 79 patients). Medial cuff failure was observed in 4 patients. Fatty atrophy of supraspinatus was significantly improved postoperatively according to Goutallier grading (p=0.01). The level of muscle atrophy of supraspinatus was not changed significantly after surgery. Conclusions: Minimal tying technique with suture configuration of four-by-four strand double-row suture-bridge yielded a lower retear rate (6.3%) in medium to large rotator cuff tears.

목적: 관절경적 이열 회전근개 봉합술은 고정력을 향상시키며 건-골 사이의 접촉면을 증가시켜 임상적 및 해부학적 결과가 우수하다는 보고들이 많고 술기 또한 여러 방법이 시도되고 있다. 저자들은 매듭 결속과 비매듭 봉합구를 동시에 사용한 관절경적 이열 회전근개 봉합술의 기능적 결과 및 구조적 연속성에 대해 보고하고자 한다. 대상 및 방법: 2006년 3월부터 2007년 6월까지 회전근개 전층 파열로 진단받고 평균 6.5개월(5~11) 보존적 치료 후 관절경적 이열 봉합술을 시행한 환자 21예(남자 15예, 여자 6예; 평균 연령 55.6세; 48~67세)를 대상으로 하였다. 관절경하에서 측정된 파열부의 크기는 소파열이 2예, 중파열이 13예, 그리고 대파열이 6예로 평균 2.5cm(1.8~3.2)이었다. 수술술기상 내측은 매듭 결속 봉합나사를 이용한 수평 매트리스 봉합술, 외측 열은 생체흡수성 비매듭 봉합구를 이용한 단순봉합술을 시행하였다. 기능적 평가는 견관절 운동 범위, ASES, UCLA scale, 그리고 등속성 근력 평가로 하였으며, 술후봉합부의 연속성은 자기공명영상으로 판정하였다. 평균 추시 기간은 15개월(13~24)이었다. 결과: 최종 추시 결과 평균 임상적 결과 지수와 근력에 있어서 유의한 호전을 보였으며(p<0.01) 19예(90.1%)에서 치료결과에 만족하였다. 술후 평균 7개월째 자기공명영상을 통해 21예중 17예(81%)에서 건 치유를 확인하였다. 술전 파열의크기에 따른 술후 견관절 기능의 차이는 통계적 유의성은 없었으나(p<0.01) 6예 대파열의 경우 3예(50%)에서 봉합부의 재파열이 확인되었다. 결론: 회전근개 파열환자에서 매듭 결속과 비매듭 봉합구를 동시에 이용한 관절경하 이열 고정 봉합술로 양호한 임상적 및 해부학적 결과를 얻었다. 이는 개방적 봉합술이나 알려진 다른 형태의 관절경적 이열 봉합술과 유사한 결과이나 생역학적 연구와 장기적 추시가 필요하리라 판단된다.

After preparation of the bone bed, two doubly loaded suture anchors with suture eyelets are inserted at the articular margin of the greater tuberosity. A retrograde suture-passing instrument penetrates the rotator cuff to retrieve the sutures through the modiWed Neviaser or subclavian portal. An ipsilateral pair of suture eyelets in the suture anchor is passed through the margins of the rotator cuff tear. The blue suture of the second and third pair is pulled out of the lateral cannula, and the threaded blue suture of the third pair in the needle is passed through the blue suture of the second pair. After retrieving the blue suture of the firrst pair through the anterior portal, it is pulled out to pass the blue suture of the third pair through the eyelet of the anteromedial anchor. The blue suture is linked between two anchors. The medial row of suture bridge is repaired with a sliding knot, and the sutures are not cut. Once the rotator cuff repair using the suture-bridge technique has been performed, the two blue strands in the anterior portal are tied. We describe our technique that possesses the advantages of both the double-pulley and suturebridge techniques, which improves the pressurized contact area and maximizes compression along the medial row.

Background: We hypothesized in this study that the characteristics of retear cases vary according to surgeon volume and that surgical outcomes differ between primary and revision arthroscopic rotator cuff repair (revisional ARCR). Methods: Surgeons performing more than 12 rotator cuff repairs (RCRs) per year were defined as high-volume surgeons, and those performing fewer than 12 RCRs were considered low-volume surgeons. Of the 47 patients who underwent revisional ARCR at our clinic enrolled in this study, 21 cases were treated by high-volume surgeons and 26 cases by low-volume surgeons. In all cases, the interval between primary surgery and revisional ARCR, degree of "acromial scuffing," number of anchors, RCR technique, retear pattern, fatty infiltration, retear size, operating time, and clinical outcome were recorded. Results: During primary surgery, significantly more lateral anchors (p=0.004) were used, and the rate of use of the double-row repair technique was significantly higher (p<0.001) in the high- versus low-volume surgeon group. Moreover, the "cut-through pattern" was observed significantly more frequently among the cases treated by high- versus low-volume surgeons (p=0.008). The clinical outcomes after revisional ARCR were not different between the two groups. Conclusions: Double-row repair during primary surgery and the cut-through pattern during revisional ARCR were more frequent in the high- versus low-volume surgeon groups. However, no differences in retear site or size, fatty infiltration grade, or outcomes were observed between the groups.

목적: 회전근 개 파열에서의 전외측 도달법을 이용한 소절개 봉합술을 소개하고자 한다. 수술 술기: 전신 마취하에 측와위 자세를 취한 후 후방 삽입구, 전방 삽입구를 이용하여 관절내 병변의 유무를 확인하고, 관절경을 견봉하 공간에 위치시킨 후 외측 삽입구를 이용하여 회전근 개의 파열 형태 및 크기를 파악한 후 관절경하견봉 성형술을 시행한다. 견봉의 전외측 연에서 하방으로 3~4 cm의 피부 절개를 가한 후 전방 및 중간 삼각근의 봉합선을 따라 박리하고 삼각근 견인기를 이용하여 시야를 확보한다. 파열된 건에 견인 봉합을 시행하여 해부학적 복원을 위한 위치를 확인한 후 봉합 나사를 이용하여 일열 혹은 이열 봉합술을 시행한다. 봉합술 후 견봉에서 삼각근이 견열되는 것을 방지하기 위해 1번 흡수봉합사를 이용하여 견봉과 삼각근과의 추가적인 봉합을 시행한다. 결론: 본 술기는 회전근 개의 가장 흔한 파열 부위인 극상건의 전방부에 직접 도달이 가능하고, 전방 및 중간 삼각근 사이로 접근하기 때문에 삽입구 연장 도달법에 비해 비교적 적은 견인으로도 시야를 확보할 수 있으며 전방으로는 견갑하건의 상부와 후방으로는 극하건까지 도달할 수 있는 유용한 술식으로 생각된다.
