At Orthopedic Department of Kyung Hee University Hospital, we performed 20 total knee replacements in 12 patients who had rheumatoid arthritis and 18 total knee replacements in 13 patients who had osteoarthritis during the period from August 1982 to May 1986. All patients were female. Comparative analysis was done between the two groups with a follow-up period ranging from 1 year to 4 years 8 months, average being 2 years and 3 months. The average age of rheumatoid arthritis patients was 10 years younger than osteoarthritis patients. The improvement of range of knee motion after total knee replacement was greater in rheumatoid arthritis comparing to osteoarthritis. Preoperative flexion contracture was more severe in rheumatoid arthritis than osteoarthritis, but after total knee replacement the average degree of flexion conrcacture was no significant difference between two groups. The average of preoperative Hospital Surgery Knee Rating Scale was low in rheumatoid arthritis group than in osteoarthritis group, but postoperative Knee Rating Scale was similar in both groups. It seems that the problem of wound was more frequent in rheumatoid arthritis than in osteoarthritis.

Kaposis sarcoma(KS) is a multicentrically developing vascular neoplasm with four types of clinical manifestation. One of these, classic KS is clinically carmcterized by late onset, chronic course and radiosensitive. We report a case of classic KS in a 72-year-old male. This pateint complainted of purple patches and dark purple nxluk. on slightly edematous lower legs. The histopathologic sections from the lesional sites showed infiltration of spindle cells with newly formed vascular slits, dilated blood vessels and aggregated hemosiderins in the dermis.

Acute Febrile Neetrophilic Dermatosis(AFND, Sweet's syndrome) ia characterixed by painful erythematous plaquea aaaociatcd with arthralgia, fever and leukocytoeis, We preagented a case of acute febrice neutrophilie denmatoeis in acutemyelogenous leukemia which occurred in a 55-year-old man. After 10 days of treatment with prednisolone, the skin lesion disapceared, but he die of pneumonia in spite of anticancer therapy.

At Orthopaedic Department of Kyung Hee University Hospital, we performed 50 total knee replacement in 32 patients who had suffered from rheumatoid arthritis during the period from Aug. 1982 to Dec. 1987. We studied these cases and compared the results of total knee replacement surgery in preoperative ambulatory patients(group I ) with those in preoperative non-ambulatory patients(group II ). 1. Preoperatively, 19 patients were able to walk, and 13 patients were unable to walk. 2. 7 patients of bilateral TKR(36.8%) were included in group I, and 11 patients (86.9%) in group II. 3. The improvement of range of motion after TKR was greater in group II (34 degrees) and in group I, average postoperative range of motion was similar to the average preoperative ROM. 4. Flexion contracture was more markedly improved in group II. 5. In group I, the average preoperative knee rating score by Hospital for Special Surgery rating system was 38.8 and improved to 93.4 postoperatively. In group II, the average preoperative knee rating score was 27.4 and improved to 85.7 postoperatively. 6. Postoperatively most of the patients were able to walk without support except one cases of infection(group I ) and the other who had severe rheumatoid involvements in other joints (group II ). 7. Preoperative evaluation for involvements of cervical spine and surrounding soft tissue structure was necessary endotracheal anesthesia. 8. There was 2 cases of complications in group I, and 4 cases in group II.
