Abstract

PURPOSE: The aim of this study was to evaluate the short-term results of total knee arthroplasty using Scorpio design. MATERIALS AND METHODS: Of one hundred thirty knees (75 patients) that were available for review at more than 12 months, 72 knees had been treated with use of a Scorpio PS design (Scorpio group) and evaluated at a mean of 20.2 months and 58 knees with use of a Scorpio SuperFlex design (SuperFlex group) and evaluated at a mean of 13.4 months. RESULTS: The mean Knee Society knee score was 90.8 points in the Scorpio group and 91.1 points in the SuperFlex group at the time of latest follow-up. As assessed at 6 month follow-up evaluation, the mean arc of active flexion was greater in SuperFlex group (119.1 vs 114. 7 degrees). However, there were no statistically significant differences in the mean arc of active flexion between the Scorpio group (119.2 degrees) and the SuperFlex group (121.3 degrees) at the time of last follow-up. CONCLUSION: There are favorable short-term results in primary total knee arthroplasy using either Scorpio PS or Scorpio SuperFlex PS design. There was no significant advantage of the SuperFlex PS design in optimizing active deep flexion as compared with Scorpio PS design at the time of last follow-up.
