In 1814, Giovanni Battista Monteggia first described two cased of fracture of proximal third of ulna with a dislocation of radial head, and this combined injury is now known as the Monteggia fracture. Despite its rarity, the importance of early recognition of dislocated radial head and correct treatment has been emphasized. Eight cases of Monteggia fracture were studied from March, 1984 to June, 1987. The results are as follows 1. Male patients were six and female were two. 2. The frequent cause of injury was fall down in four cases. 3. Bado type I accounted for 50%, type II for 12.5% and type III for 37.5%. 4. The level of ulna fracture was above upper one third of ulna in seven. 5. The common direction of dislocated radial head was anterior. 6. Two children and two adults were managed by closed reduction. 7. The results (by Bruce et al. criteria) were 3 excellent, 2 good, 1 fair and 2 poor. Four ulna fractures in adult were treated by open reduction and internal fixation using a semitubular plate.

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.

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.
