As the number of primary total knee arthroplasties (TKA) have increased, there has been a corresponding increase in the number of revision TKAs. The purpose of the this study is to report on the follow-up results of 50 revision TKAs, and to assess their clinical outcome. From January 1990 to December 1995, 50 revision TKAs were perfomed in 43 patients, by one surgeon. Mean follow up time was 2.5 years (range, 1 to 6 years). The mean interval from the initial arthroplasty to revision was 4.6 years (range, 3 months-12.6 years). The causes of the revision were wear of polyethylene in 29 joints (58%), infection in seven (14%) and aseptic loosening in six. The revision components were fixed with cement in all cases. Additional fixations were obtained with modular stems (femoral 11 cases, tibial 13 cases), 9 tibial metal wedges, 7 femoral augmentations, and 12 allografts. The Knee Rating Scale of Hospital for Special Surgery was used for clinical assessment. The mean flexion contracture and further flexion of knee joint were 8.8degrees (range, 0-70degrees), 98.5degrees (range, 5-135degrees) preoperatively, and 3.7degrees (range, 0-15degrees), 112degrees (range, 75-135degrees) postoperatively. The Knee Rating Scale improved from 66.5 points (range, 15-83) to 87.5 points (range, 79-98). There were two cases of complications, dislocation of patella and superficial wound problem in each case. In conclusion, wear was the most common cause of failure of primary TKA. The results of revision in infected TKA were less favorable than that of wear and loosening. The prosthetic design and thickness of polyethylene were the most important factors related to wear. The tibial component of PCA and patellar component of Miller-Galante had significant wear problems.

Diltiazem(Herben(R)) was orally administered in a daily dose of 180mg over 8 weeks to 15 patients with angina pectoris requiring minimum 5 tablets of nitroglycerin per week. The symptom of angina pectoris was scored according to frequency and character of anginal attacks and the number of nitroglycerin tablets used was recorded during the Diltiazem therapy. We noted significant decrease of the score of anginal attack and the number of nitroglycerin tablets used during the course of Diltiazem therapy. No significant change in blood pressure, heart rate and the product of systolic blood pressure and heart rate was noted during the course of Diltiazem therapy. It is possibel that Diltiazem improved ischemic heart disease by slightly decreasing myocardial oxygen demand and increasing blood flow to the ischemic areas by dilatation of coronary arteries and collateral vessels. There was no abnormal change in laboratory findings during the Diltiazem treatment. These findings suggest that Diltiazem(Herben(R)) is a favorable and safe antianginal agent useful for longterm treatment of anginal pectoris.

Fractures of the femur and tibia on the same leg encountered with forceful trauma. In these fractures, the treatment was difficult and the functional result was poor in most cases. Authors treated 22 fractures of femur and tibia on the same leg and analysed it. And the results were as follows. 1. The most common location of fractures was mid-third in both femur and tibia. 2. The shape of fractures was transverse or comminuted in most cases in femur and tibia. 3. Among the method of treatment of femoral fractures, the results were better in intramedullary-nailing group than plate and screw fixation group. There were three poor results in intramedullary-nailing group. These were attributed to the severity of combined tibial fractures. 4. Among the method of treatment of tibial fractures, the results were better in external fixation group which minimized the soft tissue injury than plate and screw fixation group. 5. According to the criteria of Karlstrom and Olerud, the final results were relatively good in 54% of cases. For the better results, it seemed to be needed initial careful planning and attention for the treatment.
