Purpose: The purpose of the study was to evaluate the usefulness and the stability of the superficial medial collateral ligament (MCL) release in posterior medial meniscus root repair. Materials and Methods: We compared 20 patients who underwent posterior medial meniscus root repair with superficial MCL preserved (PM) and 32 patients who underwent posterior medial meniscus root repair combined with superficial MCL release (RM) from April 2006 to September 2010. We excluded the patients combined with other surgery. To evaluate the postoperative valgus instability in RM group, we examined direct tenderness on MCL insertion, the subjective feeling of instability and valgus stress test at 3 months and 1 year follow-up. We compared the tourniquet time between PM group and RM group, and the clinical results were assessed by Lysholm score and International Knee Documentation Committee (IKDC) for the usefulness. Results: All patients had no clinically significant complication related to the superficial MCL release. Three months and 1 year follow-up, there were no positive tenderness test, no subjective symptoms and no significant increase of valgus instability although 5 patients examined grade I valgus instability. The mean tourniquet time was $41.3{\pm}12.7$ minutes in RM group and $53.5{\pm}13.6$ minutes in PM group. There was a significant difference in the tourniquet time between the two groups (P<0.05). Average Lysholm score was $56.8{\pm}5.5$ (range, 44-70) preoperatively and $85.1{\pm}5.8$ (range, 77-94) postoperatively in PM group, and was $56.2{\pm}5.4$ (range, 45-67) preoperatively and $87.4{\pm}3.9$ (range, 82-95) postoperatively in RM group (P<0.001). No significant difference of Lysholm score was found in both groups (P<0.05). Average IKDC scores was $42.6{\pm}3.9$ (range, 30-53) preoperatively and $77.2{\pm}6.3$ (range, 68-92) postoperatively in PM group, and was $42.7{\pm}5.7$ (range, 30-53) preoperatively and $89.6{\pm}2.9$ (range, 84-95) postoperatively in RM group (P<0.05). There was also no significant difference of IKDC score in both groups (P<0.05). Conclusion: The superficial MCL release in posterior medial meniscus root repair is useful to gain a wide surgical field and reduces the tourniquet time and does not lead to postoperative valgus instability. It can be considered clinically useful and safe procedure in medial meniscus posterior root repair.

Purpose: We introduce a technique of all inside arthroscopic capsular imbrication and lateral release used to treat patellofemoral instability. Methods: With the arthroscope in the anteromedial portal for best viewing, the arthroscopic scissor is placed through superolateral portal for proximal to distal release. The release performed 5mm to 1cm from the edge of the patella. After completion of the procedure, with the arthroscope in anterolateral portal, we inserted 5mm cannula in superolateral portal and made working portal from superomedial portal. Medial reefing was performed with all inside technique by using curved needle of the spectrum suturing system and No. 1 monofilament PDS suture is passed through the superomedial portal percutaneously and retrieved through a superolateral portal. Conclusion: Several methods for arthroscopic patella realignment have been proposed, but they have consisted primarily of arthroscopically assisted techniques using a medial incision. We believe that our procedure is preferable to arthroscopically assisted methods commonly used, in that an incision is avoided and the vastus medialis obliqqus is not violated. Our technique is minimally invasive and is easy to control the tightness of the medial patellofemoral ligament (MPFL) under direct vision.

Purpose: The objective of this study was to assess the clinical outcome of arthroscopic release of the extensor carpi radialis brevis (ECRB) tendon in chronic recalcitrant lateral epicondylitis and tried to determine any prognostic factors. Materials and Methods: A retrospective review of 24 patients with lateral epicondylitis treated by arthroscopic ECRB release was performed. Outcome measures included a patient self rating and visual analog scale (VAS). Functional evaluation was made with Quick-disabilities of the arm, shoulder and hand (DASH) score system to identify preoperative factors that might be associated with the outcomes. Results: Twenty one (88%) elbows received benefit from the procedure. A mean preoperative VAS pain score and the mean Quick-DASH were significantly improved at final follow up. Age, sex, dominant arm and duration of symptom, presence of capsular tear or calcification did not correlate significantly with the clinical outcome. Three of four patients without T2-weighted high signal focus of the ECRB origin on preoperative magnetic resonance imaging (MRI) showed higher Quick-DASH score. Conclusion: Arthroscopic release of the ECRB is an effective option for chronic recalcitrant lateral epicondylitis. Lack of high signal focus on preoperative MRI is significantly associated with a poor surgical outcome and a considerable factor for the proper surgical indication.

Purpose: This study seeks to address the results of percutaneous lateral release and medial reefing for patients with recurrent patellar dislocation. Materials and Methods: This paper focuses on 27 cases from 25 patients who had a surgical operation at our hospital in a span of eight years and six months from the time of December 1996 to May 2005. The subjects consist of 11 males and 14 females, and their average age was 22.2 years old. All the patients had their trauma history, and the average frequency of dislocation before surgery was 11.5 times. Results: The congruence angle before operation was 23.3 degree on the average, while the lateral patellofemoral angle was -5.7 degree on average. However, the congruence angle after surgery came to -2.4 degree, while the lateral patellofemoral angle recovered to the normal range of within 11.5 degrees. Four cases showed the recurrent dislocation, and two out of those four cases had -35, -12 degrees of their lateral patellofemoral angle respectively and 59, 14 degrees of their congruence angle respectively. Conclusion: Using percutaneous lateral release with medial reefing can be considered as an effective treatment for recurrent patellar dislocation

식도와 인두 재건은 연하작용을 원활하게하고 발선기능을 보존하면서 위험부담이 가장 절은 술식을 선택하는 것이 원칙이다. 술식의 선택에 고려되어야 할 주요 인자는 결손부위의 크기, 창상의 상태, 술전 방사선치료 여부, 환자의 전신상태 등이다. 부분인두결손에는 유경근피판(pedicled myocutaneous flap)이나 유리피판이 적합하며 방사선 치료를 받은 경우는 유리피판이 유리하다. 흉곽입구 상부에 국한된 인두와 식도의 전체둘레결손에는 전완부, 외측 대퇴부, 공장의 유리피판이 좋다. 전완부는 피판이 다루기 쉽다는 장점이 있지만 공여부에 합병증이나 미용상의 문제가 있고 외측 대퇴부는 공여부의 문제는 매우 적으나 피판의 사용이 전완부에 비하여 약간 제한적이다. 공장은 허혈에 약하고 공여부 합병증이 다른 피판에 비해 불리하다. 저자의 경험으로는 흉곽상부에 국한된 결손의 재건에 환자가 비만하거나 대퇴부에 털이 많은 경우는 전완부 유리피판이 좋고 그렇지 않으면 외측 대퇴부 유리피판을 선택하는 것이 좋다고 생각된다. 흉곽입구 하방까지 연장된 결손이나 식도전적출술로 인한 결손에는 위전위술이 가장 적합하다. 방사선치료 등으로 창상에 혈관보호가 요구되는 경우는 대흉근피판이 유용하다. 앞으로 새로운 재건술의 개발이 이어지겠지만 모든 환자에게 맞는 이상적인 재건술은 없다. 재건술마다의 장단점과 제약점을 파악하고 환자의 조건에 따라 가장 적절한 재건술을 선택하는 것이 중요하다.

Purpose: We explored the mydriatic effects of injected intracameral epinephrine after phacoemulsification (PE) combined with phacovitrectomy to treat proliferative diabetic retinopathy (PDR). Methods: We enrolled 96 patients (96 eyes) who underwent phacovitrectomy to treat PDR; we used ImageJ software to measure pupil sizes and the ratios of pupil to cornea area (PCA) before and after PE and after pars plana vitrectomy (PPV). We compared pupil sizes between those who received intracameral epinephrine (0.001% w/v) after PE but before PPV (study group, 46 eyes) and patients not so treated (control group, 50 eyes). Results: The PCA ratios of the study group were $0.52{\pm}0.11$ before PE, $0.43{\pm}0.12$ after PE, and $0.51{\pm}0.11$ after PPV, respectively. Changes in pupil size were significant (p < 0.001, p < 0.001 respectively). The PCA ratios of the control group were $0.52{\pm}0.10$ before PE, $0.39{\pm}0.15$ after PE, and $0.43{\pm}0.15$ after PPV, respectively. Changes in pupil size after PE were significant (p = 0.011) but the change after PPV was not (p = 0.056). Conclusions: Intracameral epinephrine given after PE but before PPV effectively dilates the pupils during phacovitrectomy to treat PDR.

Background: Replacement of the esophagus remains a challenge for surgeons involved in esophageal disease. From 1996 to 1999, a total of 27 patients with esophageal cancer underwent free jejunal transfer(12cases) or esophagogastrostomy(15cases). To determine the results such as leakage of anastomosis site, stenosis, reflux esophagitis and operation time, respiratory complications, etc. we reviewed the 4 years experiences. Material and method: Palliative bypass surgery or esophageal prosthesis and cancers of the pharyngoesophageal or esophagogastric junction were excluded in this study. Resection was usually peformed through right thoracotomy and anastomosis was made with EEA staplers in esophagogas-trstomy. In cases of jejunal free transfer, 6cases of proximal esophagojejunostomy were stapled anastomosed and remaining 6 cases and all distal site were hand-sewn anastomosed. All reconstruction was done through posteromediastinal route. Result: There were two mortalities from thoracic esophagogastrostomy and one from jeunal free transfer. Major and minor complications(anastomosis site leakage: 3 cases, graft failure: 2cases etc) occurred in 27 cases. In 15 thoracic esophagogastrostomy cases, 11 patients had mild to moderate reflux esophagitis and 5 patients incurred stricture of the anastomosis. Operation time was about 550$\pm$280 minutes in jejunal free transfer, and about 300$\pm$ 160 minutes in esophagogastromy patients. Conclusion: Post operative reflux esophagitis and dysphagia were more frequent in Ivor-Lewis operation group than jejunal free transfer group; however, respiratory complications and operation time were significantly longer in jejunal (roe transfer group(p<0.05). To minimize the incidence of postoperative reflux esophagitis and dysphagia, patient evaluation focused on jejunal free transfer surgery is better than esophagogastrostomy followed by adequate post operative care.
