The purpose of this study is to compare the biologic properties of tendon to hone healing and hone to hone healing in knee ligament reconstruction. The lateral 4mm of patellar tendon which was detached from its tihial insertion site either subperiostcally(group I) or with a bone block(group II) was implanted and fixed using pullout method to the proximal tihia. Ten rabbits were killed at each of four time periods (two, four, eight and twelve weeks after the implantation), and the histological and biomechanical characteristics of thc graft healing sites were evaluated. Serial histological analysis of tendon to hone healing group revealed organization of the healing site similar to normal tendon to hone attachment by twelve weeks, while hone to bone healing group demonstrated direct hony union by eight weeks. The tension failure test for the patellapatellar tendon graft - tihia complex revealed that group II had significantly higher values than group I at four and eight weeks. The findings ot this study demonstrated that bone to hone healing has more rapid process than tendon to hone healing, although no significant difference was noted once the healing has matured. We can suggest lhat the duration and extent of postoperative protection of the knee for pntients who had a reconstruction of a ligament using hone - lendon autograft should be longer and higher than lor patients who had a reconstruction using hone - tendon hone autogralf.

The concept of surface replacement arthroplasty of the hip is to replace the diseased joint surface with artificial plastic and metal cup in the acetabular and femoral head respectively, and to restore the normal anatomy and gain biomechanical function. Ten cases of Wagner type's surface replacement arthroplasty performed in Department of Orthopedic Surgery, Seoul National University Hospital since July 1979 are reviewed, and their minimum follow up is two months. In terms of the Pain control and improvement of range of motion in the hip, surface replacement arthroplasty showed about the same result compared with conventional total hip. In our cases there was no one complicatian, even though it is too short to evaluate the result of this operation. Wagner recommends surface replacement arthroplasty to perform through anterior approach, but 2 cases of our ten patients that have relatively good range of motion of the hip could be operated on this surgery by anterolateral approach (oblique skin incision) without trochanteric osteotomy, because of high incedence of myositis ossification with anterior approach. It is our conclusion that surface replacement arthroplasty of the hip may be used as an interim procedure to gain time in young patient who needs conventional total hip replacement which reveals increasing complication with the lapse of time.

There have been several reports that total knee arthroplasty(TKA) was most likely to survive successfully if the coronal tibiofemoral angle was close to 7 degree of valgus, the accepted normal. In order to know whether the postoperative coronal tibiofemoral angle influences the result of total knee arthroplasty, we examined the 152 TKA cases in 106 patients which had been performed at Department of Orthopaedic Surgery, Seoul National University Hospital from Jan. 1987 to Dec. 1991. In our series the average follow-up period was 31 months(range, 13 months to 75 months). Coronal tibiofemoral angles of all cases were checked on weight bearing anteroposterior plain X-rays and were divided into three groups(less than valgus 2° ; valgus 3° to 7° ; greater than valgus 8°). All cases were analyzed on the knee score of Hospital for Special Surgery and the American Knee Society total knee arthroplasty roentgenographic evaluation and scoring system and the cases with radiolucent lines wider than 2mm were checked. Three groups were analyzed comparatively with statistical means(Wilcoxon signed rank test, X² test). There were no significant differences in the clinical results of total knee arthroplasty according to the postoperative coronal tibiofemoral angle. Lateral subluxation of the patella occurred more frequently when the postoperative coronal tibiofemoral angle was above valgus 8°. In the tibial components of group lesser than valgus 2°, the frequency of radiolucent lines wider than 2mm was higher than those of other groups, but its significance should be examined through long term follow-up.

Although long-term studies of total knee arthroplasty(TKA) have confirmed reliable relief of pain and maintenance of function, survivorship at nine to ten years has been inconsistent with late component loosening being the most frequent mode of failure. Tibial component failure has been more frequent than failure of the femoral or patellar component in most TKA series. Encouraged by the early results of porous-ingrowh femoral and patellar components, and aware of retrieval studies showing poor bone ingrowth into tibial components, the “hybrid” method of fixation with an uncemented femoral component and a cemented tibial component, has been introduced and incorporated the potential advantages of both traditional fixation techniques. Between January 1987 and December 1991, forty-five “hybrid” TKAs(group I) were performed in degenerative arthritis and evaluated retrospectively in comparison with the results of nineteen noncemented porous-coated TKAs(group II) in degenerative arthritis. The average follow-up period was 31 months(range, 14 to 60 months) in group I and 26 months(range, 13 to 63 months) in group II. Using the knee rating scale of the Hospital for Special Surgery and the American Knee Society Roentgenographic Evaluation and Scoring System, clinical and radiological comparative study between two groups was performed. Pain scores, range of motion and HSS knee scores improved in both groups, but there was no significant difference between group I and group II(p>0.05). In both groups, the scores of radiolucent lines were significantly higher in zone 1 and 4 of A-P roentgenograph of the tibial component than in other zones(p < 0.05). The tibiofemoral angle was corrected from varus 2.7° to valgus 5.8° in group I and from varus 3.4° to valgus 4.6° in group II. There was no significant differences in component position and scores of radiolucnet lines between group I and group II. In conclusion, there were no significant differences in clinical and radiological results between the “hybrid” and the cementless groups. Results of this study suggest that both the hybrid fixation and the comentless techniques can reliably provide satisfactory clinical and radiological results in properly selected degenerative arthritis patients. But the final outcomes of this study need further evaluation through long term follow-up.
