Valgus High Tibial Osteotomy for Osteoarthritis of the Knee / 대한정형외과학회잡지

Recently there has been decreasing trend of high tibial osteotomy in management of the gonarthrotic patients partly due to recurrence of the symptom and, more importantly, due to the relative success of the total knee joint replacement procedure. But there is still room for the high tibial osteotomy, although it may be 'outdated' procedure, in that younger active patients do well postopera- tively for an enough period of time and that even the older have some gain of pain-relief in early postoperative period. The purpose of this study is to detect the affecting factors of the result of the operation. We reviewed 25 valgus high tibial osteotomies in 23 patients who had medial gonarthrosis and could be followed-up more than 1 year among 32 cases between August 1989 and January 1994. The mean length of follow-up was 30 months(ranged twelve to fifty four months). The results were compared according to modified grading of the HSS score. All cases showed the increase of the score from preop. average 65.2 points to postop. 87.8 points, mainly by the decrease of pain and the increase of functional activity. The severity of degenerative change on the radiographs and the degree of varus seemed to be related with the early clinical results of the operation, but the age was not a major affecting factor. These results could be debatable due to some differences from the others', and long term follow-up would be needed.

Arthrocopic Reconstruction of the Posterior Cruciate Ligment: The Effects of femoral attachment points and knee flexion angles at the time of graft fixation on posterior stability / 대한정형외과학회잡지

The purpose of this study is to compare the effects of the femoral attachment points of the graft and knee flexion angles at the time of graft fixation on stability of posterior cruciate ligament reconstruction. We analyzed the posterior stability of the knee on 23 patients(24 knees) with posterior cruciate ligament injury whose posterior cruciate ligament had been reconstructed arthroscopically and followed for minimum 1 year period at Asan Medical Center from May 1992 to June 1994. The patients were divided into the two groups according to femoral attachment points of the graft and knee flexion angles at the time of graft fixation. The distance from the junction of the intercondylar notch with trochlear groove of the femoral attachment points and knee flexion angles were 11mm and 0°-30° in group A and 7mm and 70°-90° in group B, respectively. 11 knees were included in group A and 13 knees in group B. Posterior stability was determined by difference in posterior tibial translation between the injured and the opposite knee with Telos device. In group A, 5 cases were at the range of 0-2mm, 3 cases 3-5 mm, 3 cases 6-10mm. In group B, 10 cases were at the range of 0-2mm and 3 cases 3-5mm, respectively. Differences in posterior tibial translation on average were 3.6mm and 1.7mm in group A and B, respectively. Conclusively, arthroscopic postrior cruciate ligament reconstruction with femoral attachment point at 7mm from the junction of interconlylar notch with trochlear groove and 70°
