The short term beneficial effect of arthroscopic excision of synovial tissue in knees with rheumatoid arthritis have been well documented. The purpose of this study to report the results of synovectomy in patients with rheumatoid arthritis who have been observed at least 3 years. We analysed the clinical result with modified Laurin criteria, radiologic change and patients own satisfaction degree with survey. The results were as follows; 1. The preoperative symptoms were pain (100%), swelling (100%), decreased range of motion (83%) and joint tenderness (74%), and those were improved postoperatively to 43%, 60%, 11%, 43% each other. 2. Among the laboratory parameters, C-reactive protein (CRP) was improved most significantly (pvalue =0.026). 3. On simple supine A-P X-rays, the width of medial joint space and lateral joint space were compared to preoperatively and postoperatively. The width of medial joint space was 4.33mm preoperatively, and it was changed to 3.22mm at last follow up (p=0.032). Those of lateral joint space was changed from 4.24mm preoperatively to 3.27mm at last tollow up (p=0.106). 4. The grade of articular cartilage damage was related with severity of preoperative symptoms and the patients with low grade of articular cartilage damage showed more postoperative improvement. The result of operation was related to symptom duration, degree of X-ray change and degree of cartilage damage. 5. 58% ot patients were satisfied to results of synovectomy, 28% were answered neither satisfied nor ansatisfied and 14% were unsatisf'ied to operation. We concluded the arthroscopic synovectomy of the knee joints was effective procedure to improve the clinical symptoms, range of knee motion and to alleviate the inflammatory reaction at mid-term period al'ter the operation. So we consider this procedure is a palliative treatment that modified and alleviate the progression of rheumatoid arthritis of knee joints.

PURPOSE: There are a few reports in the literature that deal with the results of total knee replacement arthroplasty in young rheumatoid arthritis patients. This study was undertaken to evaluate the results of total knee replacement arthroplasty in rheumatoid arthritis patients under the age of 45 years. MATERIALS AND METHOD: Between 1989 and 1993, 43 total knee replacement arthroplasties were performed in 26 adults with rheumatoid arthritis. The age at operation ranged from 23 to 45 years old (average 36.3 years). Of these, four patients (six knees) were lost to follow-up, so 37 knees in 22 patients were available for the follow-up evaluation at a mean 7.8 years (5-8.9). RESULTS: Preoperative flexion contracture was found in 33 knees (89.2%) among 37 knees and it was corrected by operation from 33.1 to 2.6 postoperatively. So the range of motion also improved by an average of 25.6 compare with preoperative state. At the time of final follow-up, six patients were free of pain and 15 patients had mild pain during weight-bearing state, but one patient, with loosening evidence complained of occasional moderate pain. The American Knee Society knee score was improved from a mean of 37.9 points preoperatively to 84.9 points postoperatively. There were 22 excellent, 14 good and one poor (loosening case) results. All patients were able to walk after the operation from 11 non-ambulators and 11 ambulators, assisted with a walking device in preoperative state. The average functional score also improved from 11.9 points to 86.8 points. Radiographic evaluation revealed a radiolucency rate of 43.2%, and revealed radiolucent line adjacent to 3 femoral and 15 tibial components. Almost all of the patients (91%) were satisfied with the result of operation, subjectively. Only one patient had a revision because of subsidency and loosening of a tibial prosthesis. CONCLUSIONS: We considered that total knee replacement arthroplasty for patients with rheumatoid arthritis and was less than 45 years old provided satisfactory and effective results.

Bilateral calcifications of the basal ganglia, the thalami, the dentate nuclei of the cerebellum, and the white matter of the cerebral hemisphere characterize Fahr's disease. The common clinical manifestations of the disease are movement disorders accompanied by cognitive impairment and mood disorder. Herein we report a case of Fahr's disease with atypical clinical manifestations. The patient was a 48 year-old man who presented with behavioral changes. His neurological examination showed no focal neurological deficits except for frontal dysfunctions. Abnormal involuntary movement was absent. Neuroimaging work-ups were compatible with Fahr's disease.

PURPOSE: This study was performed to compare the postoperative maximal flexion angle (MFA) of standard PCL-substituting (PS) prosthesis with that of high-flexion PS prosthesis after total knee arthroplasty (TKA). MATERIALS AND METHODS: A total of 81 patients (133 knees) were enrolled in this study. Sixty-eight primary bilateral TKAs were performed in 34 consecutive patients. The bilateral TKAs were performed in a staged sequential manner, with a standard PS prosthesis in one knee and a high-flexion PS prosthesis in the contralateral knee. We also analyzed the results of another 47 patients as several control groups, and this consisted of standard or high-flexion PS total knee prostheses in the bilateral TKAs, and standard or high-flexion PS total knee prostheses in the unilateral TKAs. The patients were clinically assessed with the Knee Society scoring system and the MFA was measured with a goniometer. RESULTS: At the last follow up, the mean postoperative MFA of the 34 patients operated with the combination of different prostheses was 131.6+/-10.4degrees for high-flexion prosthesis side and 131.6+/-9.5degrees for standard prosthesis side respectively. There was no statistically significant difference. On comparing with the results of the 47 patients in the control group, no statistically significant difference in the mean postoperative MFA was found between the groups. CONCLUSION: We found no significant differences between the high-flexion PS prosthesis and the standard PS prosthesis in the postoperative MFA.

OBJECTIVE: The purpose of this study is to determine the proper hand position during driving by measuring of the wheel rotation strength according to the wheel angle and hand position to the wheel. METHOD: BTE Work Simulator was used to measure the clockwise and counter clockwise static wheel rotation force of twenty healthy men in three different hand position (2~10 spot, 3~9 spot, and 4~8 spot) and two different wheel angle (45 degrees and 60 degrees), average and peak force were measured during maximal isometric contraction. RESULTS: The average and peak force was significantly different by the wheel angle, and hand position (p<0.01), but the direction of rotation didn't an effect on the rotation force. The hand position was the most significant factor, especially wheel rotation force at 2~10 spot hand position was significantly lower than that of 3~9 spot and 4~8 spot (p<0.05). The rotation force by the wheel angle was influenced by hand position, and lower in 60 degrees wheel angle in the 2~10 spot (p<0.05). CONCLUSION: The rotation force of wheel was influenced by the hand position. Therefore proper hand position is recommended during driving to reduce muscle fatigue.

OBJECTIVES: While the Korean government’s response to the coronavirus disease 2019 (COVID-19) pandemic is considered effective given the relatively low mortality rate, issues of inequality have been insufficiently addressed. This study explored COVID-19-related health inequalities in Korea. METHODS: Age standardization for various health inequality indices was derived using data from the Korean National Health Insurance Service, the Korea Disease Control and Prevention Agency, and the Microdata Integrated Service of Statistics Korea. The slope index of inequality (SII) and relative index of inequality (RII) were calculated for socioeconomic variables, while absolute difference (AD) and relative difference (RD) were used for gender and disability inequalities. RESULTS: We observed a number of COVID-19-related health outcome inequalities. Gender inequality was particularly noticeable in infection rates, with the rate of women 1.16 times higher than that of men. In contrast, socioeconomic inequality was evident in vaccination rates, with a 4.5-fold (SII, -4.519; 95% confidence interval, -7.403 to -1.634) difference between the highest and lowest household income groups. Regarding clinical progression post-infection, consistent findings indicated higher risk for men (RD for hospitalization, 0.90; severe cases, 0.54; and fatality, 0.65), individuals with disabilities (RD for hospitalization, 2.27; severe cases, 2.29; and fatality, 2.37), and those from lower socioeconomic groups (SII for hospitalization, 1.778; severe cases, 0.089; and fatality, 0.451). CONCLUSIONS While the infection risk was nearly ubiquitous, not everyone faced the same level of risk post-infection. To prevent further health inequalities, it is crucial to develop a thoughtful policy acknowledging individual health conditions and resources.
