TOTAL KNEE ARTRHROPLASTY WITH SCORPIO CR VERSUS SCORPIO FLEX CR IMPLANTS: A PROSPECTIVE EVALUATION

Abstract

Introduction: A prospective study was done to compare the early clinical, radiographic outcomes between the Scorpio CR and Scorpio Flex CR primary total knee replacement.

Methods: 130 Scorpio CR and 40 Scorpio Flex CR were implanted. Patients were prospectively evaluated with a mean follow-up of 3,9 years (2–8 years). Knee Society Score, W.O.M.A.C., range of motion and knee pain was compared. Patients age, level of activity, BMI, were criteria selection for implant of Scorpio Flex CR.

Results: There was more pain in Scorpio CR group, mean flexion was greater in Scorpio Flex CR (112 vs 108); Knee Society score and WOMAC was better in Scorpio Flex CR group.

Conclusion: The Scorpio Flex CR new design may be allow the significant increase in Knee Society score and the better ROM in Scorpio Flex CR group.
