Abstract:
PURPOSE: To evaluate the effect of posterior cruciate ligament retaining on clinical results in tota] knee arthroplasty. MATERIALS AND METHODS: Ninety-nine cases(80 patienis) of osteoarthritis were evaluated average 39 months(range 25-98 months) after total knee arthroplasty with LCS. the cases was divided into posterior cruciate retained group I(54 knees) and sacrificed group Il(45 knees). RESULTS: There was no statistically significant difference in H.S.S. knee score(I:87.4+/-6.3, II:86.1+/-5.7), range of motion(l:113.7 degrees +/- 19.8 degrees, II:111.9degrees +/-10.9 degrees), stability and roent- genographic findings, however, the functional score of the H.S.S. score was higher in group I(l: l8.2+/-5.6, II:15.3+/-4.5. p<0.05) and 6 patients with preoperative range of motion below 50 were in group II. 4 patients of 5 bilateral paired patients who ascended and descended stairs with one leg at a time prefer PCL retained side subjectively. CONCLUSION: We found no significant difference between group I and II in clinical results, however, might be that subjective symptom is excellent in group I and PCL sacrificed design seems to be effective in severely deformed knees and too tight PCL tension.
