Meniscal allograft transplantation is considered to restore important functions of the meniscus after total and subtotal meniscectomy. There are patients who need meniscal allograft transplantation have concomitant lesions; chronic anterior cruciate ligament tear, chondral defect, and malalignment of the knee. Therefore proper selection of the patients and thorough preparation of operative procedure are imperative to get satisfactory results.

회전근 개 부분 파열은 노화의 과정 중 생기는 무증상의 병변 또는 견관절 기능 장애의 잠재적인 원인으로 생각되었다. 발병 원인은 해부학적인 원인에 의한 충돌 또는 반복적 미세 외상 등이 원인으로 이해되고 있으며 병리생태에 관한 이해가 깊어지고 진단 기구, 즉 초음파나 자기공명영상, 관절경 등의 발달로 발생률이 과거에 비해 증가하고 있다. 그러나 회전근 개부분 파열은 질환 자체보다 전층 파열로 진행하는 일종의 질환 스펙트럼(disease spectrum)의 개념으로 전층 파열에 비해 현재까지 발표된 연구 자료가 많지 않다. 즉 회전근 개 부종, 견봉과의 마찰로 생긴 염증성 건병증, 회전근 개 섬유화 및 부분 또는 전층 파열로 진행되는 회전근 개 병변의 스펙트럼의 일부로 간주되는 경우가 많다. 본 종설은 회전근 개 부분 파열의 진단, 파열 분류, 수술의 적응증 및 수술 방법과 그 결과에 대해 논하고자 한다.

견관절의 다방향 불안정성은 생역학 및 생화학적 이상의 복합적 요인에 의해 발생되는 것으로 알려져 있으나 이에 대한 보다 많은 연구가 이루어져야 될 것으로 생각된다. 최근 다방향 불안정성과 관련된 요소에 따라 분류가 세분화되어 치료가 이루어지고 있다. 따라서 진단시 세심한 병력과 진찰이 매우 중요하며 이에 따라 치료 방침을 결정해야 할 것이다. 많은 환자에서 삼각근, 회전근 개, 견갑 안정화 근육을 강화시킴으로써 증상이 호전되나 비수술적 치료에 호전이 없는 경우는 관절 낭 이동술을 이용하여 비교적 만족스러운 결과를 얻을 수 있다. 일반적으로 개방적 술식이 다방향 불안정성을 위한 수술적 치료의 표준적 술식으로 알려져 있으나. 최근에는 여러 관절경적 술식이 개발되고 있고 이에 따른 중 단기 추시 결과도 비교적 좋은 것으로 보고되고 있다. 그러나 이 술식에 대한 정확한 평가를 위해서는 많은 경험과 장기 추시 결과를 요한다.

An increasing number of reverse total shoulder arthroplasty procedures has been performed since its introduction to South Korea in 2007. This review discusses the biomechanical rationale behind the development of reverse total shoulder arthroplasty and its outcomes over time. In addition, this paper mentions ways to minimize the risk of complications that may occur and how to manage those complications.

Purpose: The purpose of this study is to report a result of the technique that reconstruct posterior cruciate ligament (PCL) and posterolateral corner (PLC) simultaneously using a fresh-frozen Achilles tendon allograft. Materials and Methods: Forty two patients (45 legs) underwent PCL and PLC reconstruction were included. There were 38 males and 4 females. Mean age was 39 years. Used graft was a fresh frozen Achilles tendon allograft, which was divided by two size, larger one (${\emptyset}$ 10 mm) for PCL reconstruction and smaller one (${\emptyset}$ 8 mm) for PLC reconstruction. Arthroscopic reconstruction of the PCL was performed using transtibial, single incision, and single bundle technique with 10mm fresh frozen Achilles allograft tendon first. After PCL reconstruction, reconstruction procedure for posterolateral instability was performed using modified figure of "8" technique using smaller gtaft. For clinical evaluation, range of motion, posterior drawer test, varus stress test, prone external rotation (dial) test, Lysholm score, Tegner activity scale and posterior stress radiograph were used. Mean follow up period was 25 months. Results: Preoperatively posterior drawer test was 5 cases in grade II and 40 cases in grade III posterior instability. At final follow-up 22 cases returned within normal condition, 18 cases grade I and 5 cases grade II posterior instability. Though all patients showed positive result over 10 degrees in dial and varus stress test preoperatively, but only 9 cases showed positive both test at final follow-up. The range of motion deficit over $10^{\circ}$ flexion was 3 cases. Lysholm score was improved from mean 50 preoperatively to mean 83(p<0.05) and Tegner activity scale improved from mean 2.1 preoperatively to mean 4.6(p<0.05). In posterior stress radiographs, posterior displacement was improve from mean 16mm preoperatively to 4.1mm after treatment(p<0.05). All patients had improved compared to their pre-operative status as measured by physical examination such as posterior drawer test, varus stress test, dial test. Conclusion: We had successful results by combined reconstruction of the PCL & PLC with a fresh frozen Achilles tendon allograft in patients with PCL and posterolateral rotatory instability at a time.

Purpose: In the treatment of Dupuytren's contracture, the aim of optical treatment is to lower the recurrence rate and reduce complications. This paper reports the results of subtotal fasciectomy in Dupuytren's contracture, extending the excision of palmar fascial structures from the diseased to normal appearing adjacent fascial structure. Materials and Methods: From 2007 to 2017, 45 patients with Dupuytren's contracture treated by subtotal fasciectomy were reviewed retrospectively. The mean follow-up period was 45.9 months. Ninety-two digits were involved (index: 2, middle: 10, ring: 44, little: 36). The predisposing factors and affected joint were reviewed and the preoperative and postoperative contracture was measured. For clinical results, quick disabilities of the arm, shoulder, and hand (quick DASH) were used. Complications, including wound or skin problems, nerve injuries, hematoma, and complex regional pain syndrome, were assessed. Results: Preoperative flexion contracture was 43.2° in the proximal interphalangeal joint and 32.9° in the metacarpophalangeal joint. In nine cases, patients had residual contracture of 9.7° (range, 5°-20°) on average and if the total number of cases were included, the mean residual contracture was 2.3° on average. The quick DASH score at the 12 months follow-up was 12.4. The overall complication rate was 26.6%. Conclusion: Subtotal fasciectomy can be a good surgical treatment option for Dupuytren's contracture with a low recurrence and low complication rate compared to other open procedures.

Purpose: The proper surgical methods for treating acromioclavicular joint dislocation is still controversial. New methods should provide better early motion with sufficient strength. Materials and Methods: We performed arthroscopic stabilization using TightRope$^{(R)}$ (Arthrex, Inc, Naples, FL) in 10 cases of acromioclavicular joint dislocation between April, 2007, and December, 2007, and followup for a minimum of 10 months. We performed radiologic evaluation by comparing the clavicle anteroposterior radiograph with the contralateral one. Clinical evaluation was made for pain, function, and range of joint motion by Imatani's methods. Results: In clinical evaluation, 6 cases were excellent, 3 cases were good, and 1 case was poor. In radiologic evaluation, 9 cases were excellent and 1 case was poor. Redislocation occurred in 1 case. Conclusion: During short-term followup, 9 of 10 patients who underwent arthroscopic stabilization using TightRope$^{(R)}$ had excellent results in Imatini tests and radiologic evaluation, except 1 patient with redislocation.
