Cruciate-retaining total knee arthroplasties have had high success rates. The purpose of this study was to compare a newer cruciate-retaining design to a previously used implant to determine if there were any changes in clinical or functional outcome. A total of 461 patients (553 knees) were identified who had total knee arthroplasty with this newer design. At latest 2-year follow-up, the mean range of motion was 121 degrees (range 105 to 140 degrees), the mean Knee Society pain score was 91 points (range, 57 to 100 points) and the functional score was 76 points (45 to 100 points). The comparison group of 211 patients (225 knees) had a mean range of motion of 119 degrees at 2 years (range, 90 to 142 degrees) with Knee Society pain and functional scores of 95 and 85 points, respectively (ranges 57 to 100, and 0 to 100, respectively). The use of the newer cruciate-retaining total knee arthroplasty showed comparable results to the previously used design at short-term follow-up. The cruciate-retaining design used in this study had no early failures, though further study is needed to make assessments regarding longer-term functional results and outcomes.
