PURPOSE: Although the analgesic effect of periarticular injection after total knee arthroplasty (TKA) has been well documented, the gold standard for drug combination has not yet been established. In this study, the analgesic effects of six different drug combinations were compared. METHODS: A total of 256 patients undergoing TKA for primary osteoarthritis were randomized into one of six groups: a control group (saline solution, epinephrine, and cefazolin, n = 42), Group 1 (ropivacaine, n = 43),

PURPOSE: To evaluate the influence of postoperative tibiofemoral alignment on the clinical results and failure in patients who underwent unicompartmental knee athroplasty (UKA). MATERIALS AND METHODS: We reviewed 246 cases of medial UKA which were followed up for at least 5 years after the operation. The clinical results were compared between 5 groups classified according to the tibiofemoral angle that was measured at 3 months after surgery. We analyzed the relationship between the tibiofemoral

PURPOSE: There remains no consensus as to whether mobile total knee arthroplasty (TKA) should use a posterior cruciate ligament-sacrificing ultracongruent (UC) or a posterior cruciate ligament-substituting posterior stabilized (PS) prosthesis. The purpose of this study was to assess intraoperative kinematics and clinical outcomes of UC and PS rotating platform mobile-bearing TKA. METHODS: In this randomized controlled study, mobile UC TKA prostheses (n = 45) were compared with mobile PS TKA pros

Background: Although an appropriate hinge position to prevent unstable lateral hinge fractures is well established in medial opening wedge high tibial osteotomy, the position during medial closing wedge distal femoral osteotomy has not been elucidated. Purpose/Hypothesis: The purpose was to evaluate the ideal hinge position that would prevent an unstable lateral hinge fracture during biplanar medial closing wedge distal femoral osteotomy based on soft tissue coverage and bone density around the

A Propaganda Campaign of the Rural Community in North Korea, 1948~49: A Case Study of Injae-gun, Kangwon-do.

PURPOSE: To evaluate whether the fibular position and lateral proximal tibial geometry affect the osteotomy configuration and lateral hinge fracture (LHF) during open wedge high tibial osteotomy (OWHTO). METHODS: From March 2014 to January 2016, patients who underwent OWHTO for isolated medial compartment osteoarthritis of the knee were retrospectively reviewed. To identify whether the fibular position and lateral proximal tibial geometry affect the osteotomy configuration, the fibular height, f

Theory of peace in socialist camp in the early years of the Cold War divided the world into two parts. The one is the group for peace led by the Soviet Union, and the other is the group of warmongers led by the United States. European socialists insisted that only the group of warmongers could be the reason of the outbreaks of all kinds of wars. This kind of Antiwar Pacifism was totally different with the theory of the National Liberation War in East Asia in the early years of the Cold War. Most

이 글은 1950년부터 2015년까지 지난 65년 동안의 한국전쟁 사학사를 짚어보고 있다. 이 글은 내용적으로 기존 한국전쟁 사학사를 ‘기원과 발발’에 대한 연구와 ‘전개’에 대한 연구로 양분하여 살펴보고, ‘전개’ 부분을 다시 ‘군사사’, ‘정치사’, ‘사회사’의 세 영역으로 나누어 분석한다. 그 주요 내용을 대략적으로 살펴보면 다음과 같다. 첫째, 1990년대 러시아자료 공개 이후 한국전쟁의 국제전적 기원을 부각시키는 연구들이 다수의 국내 연구자들에 의해 발표되어 왔지만, 2000년 이후 해외학계에서는 오히려 한국전쟁의 내전적 기원을 매우 중요하게 바라보는 복합론적 인식이 널리 수용되고 있다. 둘째, 정부와 군 산하의 연구기관에서 주도해 온 한국전쟁 군사사 연구는 최근 다수의 민간연구자들에 의해 관점의 전환과 비판적 역사서술이 시도되고 있다. 셋째, 한국전쟁 정치･외교사 연구는 이론 중심의 정치학 연구에서 사료 중심의 역사학 연구로 이동해가는 경향성을 보여주었고, 사회사적 연구는

PURPOSE: Although knee joint line orientation (KJLO) after total knee arthroplasty (TKA) has been emphasized as an important factor that can affect postoperative knee kinematics, the effect of foot position on KJLO has not been fully understood. This study aimed to (1) identify the anatomical and positional factors that determine KJLO after TKA, and (2) determine the effect of foot position on KJLO after TKA. The hypothesis of this study was that the post-TKA KJLO would change depending on the d

By comparing the description of modern history in 8 different versions of 『Korean History』 high school textbooks published in 2014, this paper examines political bias prevailing in the history textbooks, which emerged as an important social issue these days. Major subjects for analysis are topics included in 8 versions of textbooks, such as the nature of the Cold War, policies of the U.S. and Soviet Union towards Korea after the Liberation, evaluation of major political powers after the Liberati

한국전쟁 발발 직후 북한은 이 전쟁이 남한의 선제 ‘북침’에 의해 시작되었다고 발표함과 동시에, 자신들의 전쟁을 소위 ‘조국해방전쟁’이라고 선언했다. 기존 연구들은 한국전쟁이 소련과 중국의 동의 하에 북한의 남침에 의해 시작되었다는 사실을 잘 보여주고 있지만, 왜 북한이 ‘북침’ 시나리오를 조작해야만 했는지 구체적으로 보여주지 못하고 있다. 이 글은 다음과 같은 새로운 역사적 사실과 주장을 제시하고 있다. 첫째, 북침 시나리오는 당대 전세계적으로 급속히 확산되고 있던 반전평화운동과 밀접한 관련을 지니고 있었다. 이 반전평화운동은 냉전 초기 소련으로부터 시작된 것으로서, 당대 사회주의진영의 결속과 확장에 중대한 기여를 하고 있었다. 둘째, 북침 시나리오는 유럽지역의 ‘반전평화’ 캠페인과 동아시아지역의 ‘전쟁’ 캠페인을 동시에 진행해야만 했던 스탈린의 고육지책이었다. 셋째, 1948~50년 소련발 반전평화론을 대대적으로 수용했던 북한 또한 민중들을 전쟁으로 동원하기 위해 남한의 북침을

AIMS AND OBJECTIVES: This study was designed to examine the contents and methods of patient educational interventions about total knee arthroplasty (TKA) and their effectiveness in reducing postoperative pain and enhancing range of motion (ROM) in the literature. BACKGROUND: Patient education has been provided to facilitate recovery after TKA; however, little is known about the contents and methods of the interventions and their effectiveness in reducing postoperative pain and enhancing ROM. DES

Abstract The purpose of this study was to compare radiologic, morphometric, and clinical outcomes between kinematically aligned (KA) and mechanically aligned (MA) total knee arthroplasty (TKA) in Korean patients. Overall, 168 patients who underwent primary TKA were retrospectively reviewed, and propensity matching (age, sex, and body mass index) was performed as 1:3 ration (KA TKAs [n = 42]: MA TKAs [n = 126]). Joint-line orientation angle (JLOA), coronal and axial alignments of implants, hip–kn

This study aimed to (1) evaluate the preoperative Hb cut-off value for transfusion after unilateral and bilateral staged (1 week apart) TKAs, respectively, and (2) determine whether cause of preoperative anemia can affect transfusion rate after TKA. A total of 951 patients who underwent TKA (unilateral: 605, bilateral staged: 346) from 2016 to 2019 were reviewed retrospectively. Patient demographics, comorbidities, preoperative Hb level, surgery types, and cause of anemia were evaluated as possi
