Total knee arthroplasty of Sledge type is difficult to perform successfully in severely damaged knee that has poor bone-stock and ligament instability. High rate of loosening has be.en found in total hinge type and kinematic rotating hinge type, so we considered use of tibia rotating prosthe,,is that allows motion with stability would be a good option. The indications of this type are severe varus deformity, bone loss, incompetent ligament, or revision. We studied 67 cases of total knee arthroplasty using Endo Model rotating total knee arthroplasty (WALDEMAR LINK GmbH & Co. Germany), which had been performed from January, 1991 to June, 1994. Thirty knees out of 67 cases were degenerative osteoarthritis, 15 posttraumatic arthritis, 11 rheumatoid arthritis, 5 revision arthroplasty, 2 sequelae of pyogenic arthritis, etc. Thirteen knees out of 67 cases had patellar resurfacement. Twenty-six out of 67 cases had bone graft. Using the Knee Rating Score of Hospital for Special Surgery, 3S were excellent and 2 l good.

Background:
The reliability and validity of the anxiety subscale of the Hospital Anxiety and Depression Scale for Koreans (K-HADS-A) has not been studied in Korean surgical patients. This study aimed to validate the usefulness of K-HADS-A for measuring preoperative anxiety in Korean surgical patients. Additionally, the effect of preoperative anxiety on postoperative quality of recovery was evaluated.
Methods:
Preoperative anxiety in 126 inpatients with planned elective surgery was measured using the K-HADS-A. The postoperative quality of recovery was measured using the Korean version of the Quality of Recovery-15. The validity and reliability of the K-HADS-A were evaluated. The differences in quality of recovery on the first and seventh day postoperatively were then compared between the anxious and non-anxious groups.
Results:
There was a statistical correlation between the K-HADS-A and Anxiety Likert Scale. The goodness-of-fit indices of the structural equation model showed how well the data from the K-HADS-A match their concept. The Kaiser-Meyer-Olkin value was 0.848, and the P value of Bartlett’s test of sphericity was < 0.001. Cronbach’s alpha was high at 0.872. The K-HADS-A had an acceptable level of validity and reliability. Postoperative quality of recovery was significantly lower in the anxious group (postoperative day 1: t = 2.058, P = 0.042; postoperative day 7: t = 3.430, P = 0.002).
Conclusions
The K-HADS-A is an acceptable tool for appropriately assessing preoperative anxiety in Korean surgical patients. Assessing preoperative anxiety is valuable, because preoperative anxiety affects the postoperative quality of mental and physical recovery.

BACKGROUND AND OBJECTIVES: Excessive catecholamine causes the alteration of cardiac structure and function. This study evaluated if there is any difference in left ventricular hypertrophy (LVH) and QTc prolongation in conditions with pheochromocytoma and Takotsubo cardiomyopathy (TC). SUBJECTS AND METHODS: We reviewed the medical records of 20 pheochromocytoma patients for cardiovascular events prior to diagnosis. The patient's clinical history and electrocardiographic and echocardiographic findings were compared to those of 20 patients diagnosed with TC. RESULTS: Left ventricular (LV) mass index (133.3+/-37.8 vs. 113.3+/-17.3, p=0.031), relative wall thickness (0.55+/-0.15 vs. 0.47+/-0.07, p=032) and elevated blood pressure (BP) were more prominent in pheochromocytoma compared to TC. The mean creatinine kinase-MB elevation, reduced LV systolic function and ST segment changes were more prominent in the TC group compared to the pheochromocytoma groups (all p<0.05). The prevalence of QTc prolongation was high in patients with pheochromocytoma (45%) and TC (55%), and TC male patients appeared to have a more prolonged QTc interval. Urine epinephrine (r=0.844, p=0.004) and norepinephrine level (r=0.782, p=0.013) were significantly correlated with LV mass index, and the predictors for the QTc prolongation were male gender and the presence of LVH. CONCLUSION: A prolonged QTc was prominent in pheochromocytoma and TC regardless of BP and systolic LV function, and LVH was more prominent in pheochromocytoma than TC.

Primary epiploic appendagitis (PEA) occurs due to inflammation of an epiploic appendage, which is a peritoneal pouch that arises from the serosal surface of the colon. PEA is often associated with infarction caused by torsion or spontaneous venous thrombosis. PEA is a self-limited disease with a course of approximately 10 days, and it requires only symptomatic management for pain. But it clinically manifests with localized abdominal pain that is often mistaken for appendicitis, diverticulitis, or cholangitis. Therefore, PEA had been diagnosed at surgery for the past few decades. Making the preoperative diagnosis of PEA through ultrasound and computed tomography (CT) has recently become possible. We report here on four cases of PEA that were diagnosed and treated by symptomatic management.

PURPOSE: To determine the incidence of truncated triangle appearance of anterior horn (AH) to body of medial meniscus (MM) and determine its clinical significance. MATERIALS AND METHODS: IRB approval was obtained, and informed consent waived for this study. The criteria of "pseudoradial tear" was truncated triangle appearance of the tip of AH to body of MM on one or more coronal images with adjacent fluid signal intensity at the blunted tip. Two musculoskeletal radiologists retrospectively evaluated 485 knee MR images independently for the presence and number of sections with "pseudoradial tear" of AH to body of MM using proton density-weighted coronal MR images. Inter-and intraobserver agreement was calculated using kappa coefficients. Medical records were reviewed for arthroscopic correlation. RESULTS: A pseudoradial tear in the AH to body of MM was present in 381 (78.6%) patients. Locations were 112 in AH (29.4%), 143 in AH to body (37.5%), and 126 in body (33.1%). Number of consecutive sections of pseudoradial tear were 1 in 100 (26.2%), 2 in 164 (43.0%), 3 in 94 (24.7%), 4 in 21 (5.5%), and 5 in 2 (0.5%). Interobserver agreement was 0.99 for presence and 0.43 for number of sections of pseudoradial tear. Arthroscopies were performed in 96 patients and none of the pseudoradial tears were proven as true radial tears on arthroscopy. CONCLUSION: Pseudoradial tears are frequently seen in AH to body of MM on coronal MR images and may be another pitfall that a radiologist needs to be aware of and be able to differentiate from true radial tear.

There have been a small number of cases of scrub typhus-associated hemophagocytic syndrome (HPS), most of which were treated successfully using adequate antibiotics. Here, we report a case of Epstein-Barr virus (EBV)-associated HPS after scrub typhus infection that was not improved using antirickettsial treatment. A 73-year-old male who had been diagnosed with scrub typhus according to an eschar and a positive serology was transferred to our institution because of a persistent fever despite 7-day doxycycline therapy. Physical and laboratory data showed hepatosplenomegaly, bicytopenia, hyperferritinemia, and hypofibrinogenemia. A bone marrow examination (BM) revealed hypercellular marrow with hemophagocytosis and histiocyte infiltration. EBV was detected in BM aspirates using polymerase chain reaction. After a diagnosis of HPS was made, the patient was treated successfully using high-dose steroids.

Background/Aims:
Gastrointestinal (GI) bezoars are relatively rare diseases with clinical characteristics and treatment modalities that depend on the location of the bezoars. This study evaluated the clinical characteristics and treatment outcomes in patients with GI bezoars.
Methods:
Seventy-five patients diagnosed with GI bezoars were enrolled in this study. Data were collected on the demographic and clinical characteristics and the characteristics of the bezoars, such as type, size, location, treatment modality, and clinical outcomes.
Results:
Among the 75 patients (mean age 71.2 years, 38 males), 32 (42.6%) had a history of intra-abdominal surgery. Hypertension (43%) and diabetes (30%) were common morbidities. The common location of the bezoars was the stomach in 33 (44%) and the small intestine in 33 (44%). Non-surgical management, including adequate hydration, chemical dissolution, and endoscopic removal, was successful in 2/2 patients with esophageal bezoars, 26/33 patients with gastric bezoars, 7/9 patients with duodenal bezoars, and 20/33 patients with small intestinal bezoars. The remaining patients had undergone surgical management.
Conclusions
The management of GI bezoars requires multidisciplinary approaches, including the appropriate correction of fluid and electrolyte imbalances, chemical dissolution, and endoscopic and surgical treatments. (Korean J Gastroenterol 2023;81:253-258)

BACKGROUND/AIMS: Ischemic colitis mainly occurs in elderly patients and encompasses a wide clinical spectrum from mild, transient to severe and gangrenous forms. Since life expectancy is now increasing, more often physicians will encounter patients with this disease entity. Our aim was to review the clinical features of ischemic colitis and to analyze the effect of clinical factors on the duration of hospital stay and evaluate predictive factors of poor prognosis. METHODS: We retrospectively analyzed the medical records of 294 patients diagnosed with ischemic colitis during 10 years from March 1997 to February 2007. RESULTS: The mean hospital stay was 12.4+/-6.6 days. According to the use of multiple regression analysis, age, sex, clinical symptoms, hypertension, constipation, use of laxatives or antibiotics did not affect hospital stay. Factors that significantly increased hospital stay were diabetes mellitus (p=0.007), colonic involvement of more than three segments (p=0.009) and the presence of an ulcer on a colonoscopic finding (p=0.008). CONCLUSIONS: Diabetes mellitus, colonic involvement of more than three segments and the presence of an ulcer on a colonoscopic finding are important predictive factors of poor prognosis in patients with ischemic colitis. In cases with one of these factors, more intensive treatment options should be adapted.
