ABSTRACT
Background: This prospective clinical study was performed to compare the clinical outcomesand radiographic changes between patients with cruciate-retaining(CR) and cruciate-substituting (CS) total knee arthroplasty (TKA).Methods: From 1997 through 1998, 228 patients (183 females and 45 males) with atotal of 267 knees with an average age of 55 years (range, 20 to 83 years)were enrolled in this study. Patients were randomly divided into two groupsincluding group I of 137 patients underwent 157 CR TKA, and group II of91 patients underwent 110 CS total knee arthroplasties. The evaluation parametersincluded knee scores, functional scores, radiographs of the knees andSF-12 surveys. The average follow-up period was 42 months (range, 24 to 66months).Results: The overall results for group I were 74.3% excellent, 17.7% good, 7.1% fairand 0.9% poor for; and 76.9% excellent, 19.2% good and 3.8% fair for groupII. No significant differences were noted in the overall results between thetwo groups. The radiographic changes showed no discernable differences.Conclusions: Cruciate-retaining and cruciate-substituting total knee arthroplasties functionequally well at 2 to 5 years postoperatively. The ultimate differences betweenthe patients who underwent CR TKA and CS TKA need to be examined afterlong-term follow up.
