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.
