Total knee arthroplaty has been used to treat the elderly patient who has severe arthritis but the early designs were associated with many problems, which frequently led to early failure. In 1974, the total knee arthroplasty was introduced and the reported results of this operation have improved consistantly with time. Recently the good results has been shown to treat rheumatoid patients and osteoarthritis patients less than 45 years old patients. At the department of orthopaedic surgery of Kosin Medical College, between 1984 and 1988, total knee arthroplasty was performed in 17 patients (22 kness) who had rhematioid arthritis (7 patients) and osteoarthritis (11 patients), and had followed for an average of 1 year and 8 months. The results were as follows 1. The knee that had rheumatoid arthritis had better knee scores than that of osteoarthritis. 2. The knee that remained the post cruciate lig. had better range of motion than that sacrificed. 3. The knees that had not used cement had better knee scores than that had used the cement. 4. The knees that had patella resulrfacing had better scores for pain than that had not.

Articular cartilage can be damaged by trauma or by progressive degradation caused by disease. Unfortunately, it has a extremely limited capacity for repair and regeneration. The use of joint prosthesis has revolutionized but remains limited in its use. To know the possibility of clinical application of clinical application of autogenous bone-articular graft in open complicated intraarticular fractures we studied the change of bone-articular cartilage defect in medial femoral condyle of rabbits and viability of autogenous bone-articular graft stored within abdominal wall of rabbits. The results were obtained as follows: 1. There was over 90% viability of subchondral bone after 10 days storage in the adbominal wall but the articular cartilage showed degenerative change about 40% after 5 days passed. 2. The bone-articular defect was replaced by undifferentiated mesenchymal tissue and fibrous tissue, postoperative 6 weeks later. 3. In implanted bone-articular cartilage graft at 3 days, the chondrocyte of basal cell layer in articular cartilage was relatively well preserved but in 7 days, transplanted articular cartilage graft showed almost necrotic chage. Most of subchondral bones were well healed with host bone without regard to duration of implantation.

BACKGROUND: Drug-induced Parkinsonism(DIP) is the second commonest cause of Parkinsonism, after idiopathic Parkinson's disease(IPD). DIP is frequently produced by antipsychotic drugs. But the clinical characteristics of DIP did not get attention by neurologist. So we studied the clinical profiles of DIP patients. METHODS: We studied the clinical profiles of thirthone patients who showed parkinsonism after antipsychotic drug treatment. We compared the score of motor part of the Unified Parkinson's Disease Rating Scale(UPDRS) between trihexyphenidyl(n=15) & amantadine(n=16) monotherapy group(initial & 4 week after treatment). RESULTS: The mean age of patients was 45 years. Bradykinesia was the 1st symptom in 26 patients(94%), tremor in 5 patients(6%). In 25 patients(81%), the first symptom appeared within 1 week after sntipsychotic treatment. There was a statistical significant negative correlation between the dosage of antipsychotic drug and the symptom-onset interval following treatment with antipsychotic drugs(simple correlation analysis, p>0.01). Bradykinesia and rigidity were appeared in all DIP patients, symmetric distribution was more common(94%, 87%) Tremor occurred in 27 patients (87%). In patients with tremor, postural or action tremor was dominant in 15 patients(56%) asymmetric distribution was more common(16/27, 59%). There are no statistical difference in motor score of UPDRS between trihexyphenidyl & amantadine monotherapy group(student t-test, p<0.05) CONCLUSIONS: Bradykinesia was the most common 1st symptom in DIP patients. Asymmertrical postural or action tremor was relativelly common in DIP. Amantadine showed the same efficacy in the treatment of DIP compared to anticholinergics.

Hyperplasia of the gingivae may occur as a secondary reaction in the treatment of epilepsy with diphenylhydantoin sodium. This study is intended to investigate the incidence and dharacteristics of gingival hyperplasia in 124 epileptic patients taking diphenylhydantoin longstandingly. The results are as follows: 1. The incidence of diphenylhydantoin induced gingival hyperplasia is approximately 69.4%. 2. The individual tolerance or sensitivity may determine the incidence and severity of gingival hyperplasia and are not directly related with the duration of drug use and its dosage. 3. Gingival hyperplasia is more frequent in female patients and younger patients than male and older. 4. There is no direct relationship betwwen occurance of gingival hyperplasia and meticulous oral hygiene. 5. The mechanism involved in a causation of diphenylhydantoin induced gingival hyperplasia has not been elucidated. 6. We recommand that diphenylhydantoin may be prescribed as the drug of the first choice for the control of epileptic seizure in the adolescent female patients and children especially receiving certain dental treatments.

BACKGROUND: Intracranial lipomas are uncommon benign lesions of the central nervous system. They preferentially occur near the midline, most frequently in the pericallosal cistern, and are often associated with various neurologic and systemic anomalies. Since the advent of CT scanning and MR imaging, unexpected findings of intracralial lipomas have increased. We identified 11 cases of intracranial lipomas diagnosed by CT and MR and analyzed their characteristic clinical and radiologic findings. METHODS: We retrospectively reviewed 11 cases of intracranial lipomas. MR was used in all cases and CT in three. RESULTS: There were seven men and four women whose ages ranged from six months to 76 years, with a mean of 39 years. Six (55%) lipomas were located in the quadrigeminal plate and five (45%) in the pericallosal area. The pericallosal lipomas were divided into three cases of curvilinear type and two cases of tubulonodular type. Of the six quadrigeminal lipomas, five cases (83%) were associated with either hypoplasia of the unilateral (four) or bilateral (one) superior and/or inferior colliculus. One case of quadrigeminal lipoma was associated with hypoplasia of the cerebellar vermis, agenesis of the septum pellucidum, and glioblastoma multiforme. All cases of pericallosal tubulonodular type were associated with dysgenesis of the corpus callosum and enlarged ventricles. However, all cases of pericallosal curvilinear type were not associated with other anomalies. Four (36%) cases found incidentally were asymptomatic. Seizure was the most frequent clinical presentation in five (45%) cases, followed by headaches in three (27%) and mental retardation in one (9%). Of five seizures cases, three had secondary generalized seizures and two had generalized tonic clonic seizures. CONCLUSIONS: Quadrigeminal and pericallosal lipomas were the most common types of intracranial lipomas. Sixty-three percent of the lesions were associated with adjacent brain malformations of varying degrees. Four cases were asymptomatic, while the others presented with seizures, headache, and mental retardation. (J Korean Neurol Assoc 19(2):149~154, 2001)

Purpose: This study evaluated the clinical and radiological outcomes of TFNA (Trochanteric Fixation NailAdvanced; Depuy Synthes) for the treatment of proximal femur fractures. Materials and Methods: This was a retrospective study of 64 patients diagnosed with a proximal femur fracture from January 2019 to November 2019. The patient’s demographic data, preoperatively and postoperatively Koval grade, modified Harris hip score, EQ-5D (Euro-Qol-5 Dimension), sliding and advancement of the blade, radiologic outcome, and complications were investigated. Results: Fifty patients were available for evaluation at one year postoperatively. The patients reported the following: the Koval grade decreased after surgery; the modified Harris hip score decreased from 78.56±8.88 to 72.74±6.59 (p=0.149); the mean EQ-5D decreased from 0.75±0.09 to 0.72±0.06 (p=0.000). Satisfactory reduction was achieved on a postoperative radiographic examination in 47 patients in six months. Complications occurred in seven cases. Conclusion TFNA is considered an appropriate implant for treating intertrochanteric fractures of the femur with a minimum follow-up of one year.
