Forty nine cases of the proximai tibial metaphyseal fractures treated and managed at the Department of Orthopedic Surgery, Severance Hospital from Jan. 1971 to Dec. 1980 were analysed in inclinical and radiological aspect. The results obtained from this study were as followings: l. Among the 49 patients, male were 30 patients and female 19 patients (M:F=1.6:1). 2. The main cause of the fractures was the traffic accident, 42 cases (85.7%). 3. The most common type of the fractures was the transverse fracture, 21 cases (42.9%). 4. The better prognosis of the treatment was the closed reduction. 5. The better prognosis of the fracture type was shown in the transverse fracture and the poor prognosis was in the anterior long oblique fracture. 6. In the union time of the fracture, there was no significant differences between the proximal tibial metaphyseal fracture and the tibial shaft fracture.

We performed twenty three cementless total hip arthroplasties(THA) on seventeen patients, all of whom were diagnosed with steroid-induced avascular necrosis of the hip (AVN). The average age of the patients was 41years, mean follow-up period was 41months (24-74months). The final average Harris hip score was 94 and overall results were excellent. On radiographic evaluation, 17 femoral components met the criteria for bone ingrowth(spot weld) but it was somewhat delayed. There was no evidence of loosening of the femoral and acetabular components. The results of this study suggest that long term steriod treatment does not prevent bone ingrowth. Cementless total hip arthroplasty appears to be a reasonable therapeutic option for steroid-induced avascular necrosis of the hip.

Eighty primary Harris-Galante Porus (HGP) total hip replacements were performed at Severance Hospital from January 1986 to January 1989. A minimum of 18 months follow-up was available for 80 hips in 72 patients, whose mean age was fifty two years. The most common presenting diagnosis was avascular necrosis (47.5%) followed by fused hips (10%), tuberculosis (10%), rheumatoid arthritis (7.5%). Complications included three calcar cracks and two immediate dislocations and 6 cases of mild myositis ossificans. There were no infections and no revisions. The mean Harris hip score was 93 points (range, 74–100 points) at two years. The thigh pain was in nine patients (11 per cent) at one year and in three patients (3 per cent) at two years postoperatively. Radiographic analysis revealed that, a progressive radiodense femoral line developed in 21 hips (26 per cent); a progressive acetabular line in 3 hips (4 per cent); and decreased proximal femoral density in 28 hips (35 per cent). There were no position change of the acetabula and femoral compent. We conclude that the early overall clinical results of HGP total hip replacements are encouraging, at average 30 months. The prognostic significance of the radiographic changes such ar radiodense lines, the changes of the proximal femur and cortical thickening, have to be determined with longer follow-up. Long term follow-up of uncemented HGP total hip replacement is necessary to evaluate the efficacy of such implants.

The results of cementless total knee arthroplasty(TKA) have improved steadly during the past decade due to development of design, fixation and surgical technique. We analyzed the results of 45 total knee arthroplasties performed with Anatomic Modular Knee(AMK) prosthesis at the department of Orthopedic Surgery, Yonsei University College of Medicine between June 1989 and December 1991 and compared their results of rheumatoid arthritis(RA) and osteoarthritis(OA) patients. The follow up ranged from 2 years to 4 years and 2 months (average 2 years and 8 months). Using the Hospital for Special Surgery(H.S.S.) rating system and Knee Society(K.S.) clinical rating system, we found that the clinical results were similar for RA group(Average; H.S.S. 86.1, K.S. 81.2/74.4) and OA group(Average; H.S.S. 88, K.S. 87.8/77.1) even though the preoperative knee score was lower in RA group(Average;H.S.S.42.8) than OA group(Average;H.S.S. 57.7). The average age of RA patients was 14 years younger than that of OA patients. The improvement of range of motin and preoperative flexion contracture after TKA was remarkable in RA group. The radiologic evaluation based on Knee Society roentgenographic evaluation system revealed proper alignment of all component and no definite radiologic loosening except 1 case in which postoperative deep infection had occurred. On the basis of this prospective clinical and radiologic review, we concluded that uncemented implantation of AMK prosthsis both in RA and OA patients was encouraging.

The posterior cruciate ligament in the stoutest ligamentous structure in the knee joint. Kennedy and Hawkins have confirmed its strenght to be about 2 times that of the anterior cruciate ligament or tibial collateral ligament. This would appear to offer the support that this ligament has a vital role to play in knee stabilization. But, in the past, non-surgical management was frequently elected either because of the belief that most kness with posterior cruciate insufficiency are asymptomatic or because it is difficult to access surgically. Recently, Hughston and Trickey reported good results after surgical repair of the rupture of the posterior cruciate ligament. And current trend is to repair it surgically. So, we analyzed the 36 cases of acute posterior cruciate ligament injuries, who were admitted and treated surgically in Severance Hospital between Jan. 1981 to Dec. 1985, and obtained the following results. 1. Single rupture of the posterior cruciate ligament largely results in good outcome. 2. When the rupture site is in the substane, we can obtain relatively good results with the augmentation using the medial head of the gastrocnemius. 3. When combined with medial or lateral compartment injuries, the chance of later instability and reconstruction is high.

We performed 75 cases of daryocystorhinostomy from Jan. 1988 to Dec. 1990. A routine dacryocystography was performed prior to operation in all cases. A modified T oti's method was applied as a surgical technique "H" shaped incision was done. Both anterior and posterior flaps were sutured adequately and vaseline guaze was used as a plugging agent for 7 to 10 days Success was achieved in 72(96.0%) of 75 cases. The causes of 3-failures were organized granulation tissue and trauma.
