        Purpose: We evaluated the efficiency of low contact stress(LCS) system in total knee arthroplasty by analyzing clinical and radiological results. Materials and Methods: Out of 128 cases who underwent total knee arthroplasty with meniscal bearing type LCS system, eighty one cases who were followed up for more than two years were analysed. Average follow-up period was 32.6 months(24 months-48 months). The diagnoses were six cases of degenerative arthritis, eighteen cases of rheumatoid arthritis, and two cases of avascular necrosis. Clinical analysis were performed by American Knee Society Knee Score and Hospital for Special Surgery(HSS) knee score and radiographic analysis were performed by the Knee Society Roentgenographic Evaluation and Scoring System. Results: Average preoperative flexion contracture was improved from 13.4 degrees preoperatively to 1.2 degrees at final follow-up and average arc of motion was changed from 107 degrees preopeatively to 108 degrees at final follow-up without significant improvement. American Knee Society Knee Score was improved from average 55.2 preoperatively to 88.5 at final follow-up. HSS knee score also showed improvement from average 58.2 to 86.5. Tibio-femoral angle was improved from 6.3 degrees of varus preoperatively to 5.1 degrees of valgus at final follow-up. Radiolucent lines was seen most commonly at zone 1 in anteroposterior radiograph of tibia and in zone 1 in lateral radiograph of femur. Complications such as superficial wound infection, stiffness, and meniscal bearing fracture were seen in four cases. Conclusion: Total knee arthroplasty using LCS system showed satisfactory improvement in flexion contracture, deformity correction. Clinical and radiographic result.

        Malignant tumors of the hand are very rare. Between 1989 and 1998, 17 patients with malignant tumors of the hand were evaluated for clinical features, prevalence, treatment and results. The mean age was 45 years and median duration of follow-up was 38 months. A painless mass was the most common symptom and the most common lesion was the digit. Fifteen cases of soft tissue and 2 cases of bone tumor were diagnosed. On pathology, soft tissue tumors were comprised of 8 cases of malignant melanoma, 2 cases of angiosarcoma and 1 case each of malignant fibrous histiocytoma, malignant peripheral nerve sheath tumor, extraskeletal chondrosarcoma, and squamous cell carcinoma. Bone tumors were metastatic tumors and each originated from the rectal cancer or lung cancer. Lymph node involvements were noted in 4 cases of malignant melanoma and 1 case of squamous cell carcinoma. Six cases of metacarpo-phalangeal joint disarticulation and 4 cases of phalanx amputation were performed. Wide excision, ray amputation and below-elbow amputation were also performed. Three cases expired due to metastasis and progression of the original lesion. Among the surviving 14 cases, a malignant melanoma had metastasis on the axillary lymph node and 13 cases showed no local recurrence or metastasis during the follow-up.
