A new modified inside-out repair technique of arthroscopic meniscal repair for peripherally torn menisci is described. Under arthroscopic control, after conventional inside-out technique using meniscal repair set using outside-in technique with 18-gauge needle, horizontal mattress sutures of absorbable monofilament(PDS 2-0) were placed across the tom site and tied over the capsule or fascia. Nearly all portions of meniscus were possible with this technique except most posterior and anterior portions. As this is the modification of inside-out technique, neurovascular complications could be avioded. The problem of outside-in technique, knot irritation inside joint could be avoided also because the knot is outside of the joint.

In Korea, the incidence of acute myocardial infarction has been increasing rapidly. Twelve-month clinical outcomes for 13,133 patients with acute myocardial infarction enrolled in the nationwide prospective Korea Acute Myocardial Infarction Registry study were analyzed according to the presence or absence of ST-segment elevation. Patients with ST-segment elevation myocardial infarction (STEMI) were younger, more likely to be men and smokers, and had poorer left ventricular function with a higher incidence of cardiac death compared to patients with non-ST-segment elevation myocardial infarction (NSTEMI). NSTEMI patients had a higher prevalence of 3-vessel and left main coronary artery disease with complex lesions, and were more likely to have co-morbidities. The in-hospital and 1-month survival rates were higher in NSTEMI patients than in STEMI patients. However, 12-month survival rates was not different between the two groups. In conclusion, NSTEMI patients have worse clinical outcomes than STEMI patients, and therefore should be treated more intensively during clinical follow-up.

Background The benefit of statin use after acute ST-segment elevation myocardial infarction (STEMI) has been well established, however, the influence of the timing of statin administration has not been elucidated. The objective of this study focused on early clinical outcomes after percutaneous coronary intervention (PCI). Methods This analysis of the Korea Working Group on Myocardial Infarction registry (KorMI) study included 3,584 STEMI patients (mean age, 63 ±13 years;male, 2,684, 74.9%) undergoing PCI from January 2008 to June 2009. Rates of major adverse cardiac events (MACE:all-cause death, recurrent MI, and target lesion revascularization) were compared among patients grouped according to statin therapy timing:I, both during and after hospitalization (n=2,653, 74%);II, only during hospita-lization (n=309, 8.6%);III, only after discharge (n=157, 4.4%);and IV, no statin therapy (n=465, 13%). Mean follow-up duration was 234 ± 113 days. Results Multivariate factors of statin use during hospitalization included prior statin use, multiple diseased vessels, final thrombolysis in myocardial infarction flow grade III, and low-density lipoprotein cholesterol level. At 6-month follow-up, groups III and IV had the highest MACE rates (2.3%, 3.9%, 5.1%, and 4.9%for groups I-IV, respectively, P=0.004). After adjusting for confounders, groups II-IV had a higher MACE risk than group I [hazard ratio (HR):3.20, 95%confidence interval (95%CI):1.31-7.86, P=0.011;HR:3.84, 95%CI:1.47-10.02, P=0.006;and HR:3.17, 95%CI:1.59-6.40, P=0.001;respectively]. Conclusions This study, based on the national registry database, shows early and continuous statin therapy improvs early outcomes of STEMI patients after PCI in real-world clinical prac-tice.

Coronary artery disease, especially acute myocardial infarction (AMI), is a leading cause of death in the Asia-Pacific region. The Korea Acute Myocardial Infarction Registry (KAMIR) is the first nationwide, prospective, multicenter registry of Korean patients with AMI. Since the KAMIR first began in November 2005, more than 70,000 patients have been enrolled, and 230 papers have been published (as of October 2018). Moreover, published data from the KAMIR have revealed different characteristics from those of Western AMI registries regarding risk factors, interventional strategies, and clinical outcomes. As a result, the KAMIR study has improved the outcomes of percutaneous coronary intervention and reduced mortality. We propose the use of the KAMIR score in the prediction of 1-year mortality. Using data from the KAMIR, we provide an overview of the current status of AMI in Korea, including trends in demographic characteristics, risk factors, medications, treatment strategies, and clinical outcomes.

Intracoronary stent implantation can improve coronary hemodynamics and myocardial ischemia in patients with symptomatic bridging. However, percutaneous coronary intervention for this lesion is limited due to the high prevalence of restenosis and risk of complications. We present a case of a totally occluded long-segment myocardial bridge in a patient with hypertrophic cardiomyopathy who was successfully implanted with a bare metal stent under intravascular ultrasound guidance without complications. The patient has been free of ischemic symptoms with stent patency for 10 years.

As the first nationwide Korean prospective multicenter data collection registry, the Korea Acute Myocardial Infarction Registry (KAMIR) launched in November 2005. Through a number of innovative approaches, KAMIR suggested new horizons about acute myocardial infarction (AMI) which contains unique features of Asian patients from baseline characteristics to treatment strategy. Obesity paradox was existed in Korean AMI patients, whereas no gender differences among them. KAMIR score suggested new risk stratifying method with increased convenience and an enhanced accuracy for the prediction of adverse outcomes. Standard loading dose of clopidogrel was enough for Asian AMI patients. Triple antiplatelet therapy with aspirin, clopidogrel and cilostazol could improve clinical outcomes than dual antiplatelet therapy with aspirin and clopidogrel. Statin improved clinical outcomes even in AMI patients with very low LDL-C levels. The rate of percutaneous coronary intervention was higher and door-to-balloon time was shorter than the previous reports. Zotarolimus eluting stents as the 2nd generation drug-eluting stent (DES) was not superior to the 1st generation DES, in contrast to the western AMI studies. KAMIR made a cornerstone in the study of Korean AMI and expected to be new standards of care for AMI with the renewal of KAMIR design to overcome its pitfalls.

PURPOSE: To evaluate retrospectively the results regarding pain relief, complication after percutaneous vertebroplasty, for an osteoporotic compression fractures. MATERIALS AND METHODS: 260 patients (male 55, female 260, mean age 69.4 years old) treated by percutaneous vertebroplasty in Dankook University Hospital from July 1997 to July 2004 were reviewed. We performed percutaneous vertebroplasty and observed the degree of pain relief using pain scale pre-/postoperation. we evaluate the complication by plain radiographs and computed tomography, ABGA and chest X-ray. we evaluate pain relief and complication for 1 week by follow-up plain radiographs. we recommended BMD follow-up per 1 year and osteoporosis medication at least 2 years. A clinical result was evaluated as excellent, good, fair, poor and visual analogue scale (VAS 0~10) for 1 year. We prefaced a statistical analysis by T-test using SPSS (version 11.0) correlating 1 week and 1 years effects. RESULTS: 73 (28.3%) of the patients were evaluated as excellent: 123 (45.5%), as good: 45 (17.8%), as fair; and 23 (8.5%), as poor, show 73.8% over good in 1 week. 76 (29.3%) of the patients were evaluated as excellent; 120 (44.3%), as good; 43 (16.8%), as fair; and 25 (9.6%), as poor in 1 year, show 73.6% over good result. 1 week follow-up and 1 year follow-up show similar results. 1 patient had death (hemothorax), 4 patients had arrhythmia, 15 patients (21 vertebrae) had fracture around vertebroplasty. CONCLUSION: Percutaneous vertebroplasty using PMMA is valuable method in the treatment of osteoporotic compression fracture, providing immediately pain relief, long term pain relief, prevention of complication originated from long term traction and bed rest, unwearing brace and early ambulation.
