Purpose: The purpose of the present study was to compare and analyze the clinical outcomes of the percutaneous and open repair of acute Achilles tendon ruptures. Materials and Methods: We performed a retrospective study on 24 patients (group 1) managed with percutaneous repair, and 21 patients (group 2) managed with open repair for acute Achilles tendon rupture. The postoperative evaluations were done by an Arner-Lindholm scale and AOFAS score. Postoperative overall satisfaction and cosmetic satisfaction were also evaluated. Results: By Arner-Lindholm scale and AOFAS score, there was no difference between two groups (p<0.05). As for postoperative overall satisfaction, 5 cases were very satisfied, 16 cases were satisfied and 3 cases were fair in group 1. In group 2, 12 cases were very satisfied, 9 cases were satisfied. For postoperative cosmetic satisfaction, 13 cases were satisfied, 11 cases were fair in group 1. In group 2, 9 cases were very satisfied, 12 cases satisfied. In open repair group, a case of deep wound infection and three cases of skin necrosis were reported as complication. 2 cases of sural nerve injury were seen in percutaneous repair group and were recovered within 3 months. Conclusion: Percutaneous repair of acute Achilles tendon ruptures have high level of cosmetic satisfaction compared with open repair without any significant difference in clinical outcomes.

Background: There have been a number of studies on mitral valve replacement and repeated percutaneous mitral balloon valvotomy for mitral valve restenosis after percutaneous mitral balloon valvotomy. However, studies on mitral valve repair for these patients are rare. In this study, we analyzed postoperative outcomes of mitral valve repair for mitral valve restenosis after percutaneous mitral balloon valvotomy. Methods: In this study, we assessed 15 patients (mean age, $47.7{\pm}9.7years$; 11 female and 4 male) who underwent mitral valve repair between August 2008 and March 2013 for symptomatic mitral valve restenosis after percutaneous mitral balloon valvotomy. The mean interval between the initial percutaneous mitral balloon valvotomy and the mitral valve repair was $13.5{\pm}7years$. The mean preoperative Wilkins score was $9.4{\pm}2.6$. Results: The mean mitral valve area obtained using planimetry increased from $1.16{\pm}0.16cm^2$ to $1.62{\pm}0.34cm^2$ (p=0.0001). The mean pressure half time obtained using Doppler ultrasound decreased from $202.4{\pm}58.6ms$ to $152{\pm}50.2ms$ (p=0.0001). The mean pressure gradient obtained using Doppler ultrasound decreased from $9.4{\pm}4.0mmHg$ to $5.8{\pm}1.5mmHg$ (p=0.0021). There were no early or late deaths. Thromboembolic events or infective endocarditis did not occur. Reoperations such as mitral valve repair or mitral valve replacement were not performed during the follow-up period ($39{\pm}16months$). The 5-year event-free survival was 56.16% (95% confidence interval, 47.467-64.866). Conclusion: On the basis of these results, we could not conclude that mitral valve repair could be an alternative for patients with mitral valve restenosis after percutaneous balloon mitral valvotomy. However, some patients presented with results similar to those of mitral valve replacement. Further studies including more patients with long-term follow-up are necessary to determine the possibility of this application of mitral valve repair.

An atrial septal defect is the most common type of congenital heart disease among adults. Surgical repair or percutaneous closure of the defect is the treatment options. Even though percutaneous closure seems to be less risky than surgical repair, it may result in fatal complications like device embolism, cardiac perforation and tamponade. Herein we report a case of the embolism of a device into the pulmonary artery after one hour of percutaneous closure in which the embolized device was surgically removed and the defect was closed with a pericardial patch.

Purpose: To investigate the results of percutaneous repair technique of Achilles tendon ruptures, and to describe the surgical technique. Materials and Methods: We retrospectively analyzed the outcomes of 73 patients with ruptured Achilles tendon from October 1995 to September 2009. 28 patients were excluded due to short follow up period. 34 patients were male and 11 patients were female. The mean patient age was 37.19 (10~62) years. The location of rupture site was 6.58 cm proximal to the tendon insertion into the calcaneus on average. Mean follow up period was 55 months and All patients were surgically repaired using percutaneous technique with sural nerve isolation. Results: Arner-lindholm score were excellent in 32 (71%), good in 12 (27%), poor in 1 (2%) case. 44 cases (98%) had the score more than good. Mean American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot function score was 92.93 (67~100). We had 1 case of superficial infection, 1 case of soft tissue irritation by suture knot. Conclusion: Percutaneous repair with sural nerve isolation in treating ruptured Achilles tendon showed low complication rate and reliable clinical outcome.

Purpose: This study compared the clinical outcomes of open repair, percutaneous repair, and minimal incision repair by Achillon in ruptured Achilles tendon. Materials and Methods: The outcomes of 12 patients with open repair (group 1), 8 patients with percutaneous repair (group 2), and 10 patients with minimal incision repair by Achillon (group 3) from February 2013 to March 2016 were analyzed retrospectively. The postoperative clinical evaluations were done by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Arner-Linholm scale, mid-calf circumference difference, one-leg heel raise difference, visual analogue scale (VAS) for postoperative scarring, time to return to work, and complications. Results: No significant difference in the AOFAS ankle-hindfoot score, Arner-Linholm scale, and time to return to work was observed among three groups (p=0.968, 0.509, and 0.585). The mean differences in the mid-calf circumference in groups 1, 2, and 3 were 1.09, 0.73, and 0.58, respectively; groups 2 and 3 were significantly higher than group 1 (p=0.002). In addition, the mean VAS scores for postoperative scarring in groups 1, 2, and 3 were 7.0, 9.1, and 9.1, respectively; groups 2 and 3 were significantly higher than group 1 (p=0.001). The mean differences in one-leg heel raising in groups 1, 2, and 3 were 2.03, 1.91, and 1.33, respectively; group 3 was significantly higher than groups 1 and 2 (p=0.010). The complications encountered were one case of deep infection in group 1 and one case of sural nerve hypoesthesia in group 2. Conclusion: Minimal incision repair by Achillon is recommended as an effective surgical treatment for Achilles tendon rupture because it minimizes the risk of complications, leads to an improved tendon strength and healing, and achieves cosmetic satisfaction.

Purpose: To evaluate the clinical validity of percutaneous screw fixation in Maisonneuve fracture. Material and Methods: Out of 5 Maisonneuve fracture patients hospitalized in the department of orthopedic surgery of Seigang hospital from February 1995 to May 1998, 4 patients were treated with percutaneous screw fixation and 1 patient was treated with percutaneous screw fixation and repair of deltoid ligament altogether. The results were evaluated on the clinical and radiological finding. Results: In all cases, the range of motion of ankle joint was normal, the complication such as postoperative pain and post-traumatic arthritis were not found. Widening of medial clear space or talar shift were not found in the follow up X-ray and tibiofibular distance, compared with normal ankle joint was same on follow up CT. Conclusion: Percutaneous screw fixation is simple, less invasive and more effective method in the treatment of Maisonneuve fracture.

A 68-year-old man presented with a posterior tracheal wall injury caused by percutaneous dilatational tracheostomy. The wound was immediately covered with an absorbable polyglycolic acid sheet. Ten days after the injury, the perforation was closed with knotless sutures using a Castroviejo needle-holder through the tracheostomy. The successful repair in this case indicates the feasibility of the knotless suture technique for perforations. The technique is described in detail in this report. The patient was weaned from the mechanical ventilator on postoperative day 25. In cases of posterior tracheal posterior wall perforation, every effort should be made to repair the perforation through an existing opening.

Purpose : This study was performed to compare the safety, efficacy and clinical results of the Amplatzer septal occluder (ASO) for closure of secundum atrial septal defect (ASD) with surgery. Methods : One hundred fifteen patients diagnosed as isolated secundum ASD in Gil Medical Center, Gachon University of Medicine from January 2000 to July 2006 were included. Seventy patients underwent surgical repair of ostium secundum ASD. Forty-five consecutive patients were treated with percutaneous closure using ASO. We compared the mortality, morbidity, hospital stay, and efficacy between two groups. Results : Male to female ratio was 1:2.4. The mean age and the size of defects were not statistically different. No mortality occurred in either group. The success rate was 97.8% in the device group and 100% in the surgical group. The overall rate of complications was higher in the surgical group than in the device group (64.0 vs. 15.6%, P<0.05). Hospital stay was shorter in the device group than in the surgical group ($4.2{\pm}1.2$ vs. $12.4{\pm}4.7days$, P<0.0001). Residual shunt rates were more frequent in the device group (8.9%) than in the surgical group (4.3%) at discharge. All residual shunts disappeared at 3 months follow-up. Conclusion : Percutaneous closure of ASD using ASO is a safe and effective alternative to surgical repair. The indications of percutaneous ASD closure with ASO would be expanded by accumulation of experiences and evolutions of device.

A 53-year-old man presenting with dyspnea and chest pain was diagnosed with acute myocardial infarction secondary to occlusion of the left circumflex coronary artery. Urgent revascularization by percutaneous stenting was successfully performed. However, the post-echocardiography revealed a ruptured papillary muscle that was causing severe mitral regurgitation and aggravation of congestive heart failure. The patient subsequently underwent mitral valve repair with papillary muscle re-implantation. Postoperative echocardiography showed a competent mitral valve without residual stenosis or regurgitation. The patient was discharged from the hospital with an uneventful recovery and has been doing well on outpatient follow up.
