A Gender-Specific Posterior Cruciate-Substituting High-Flexion Knee Prosthesis Does Not Improve Fit and Function

Phase 4

Completed

• Conditions: Osteoarthritis of the Knee; Female

• Registration Number: NCT00917774
• Lead Sponsor: Ewha Womans University

Brief Summary

The purpose of this study was to compare functional and radiographic results, range of motion of the knee, patient satisfaction, femoral component, revision and complication rates in patients receiving either a standard posterior cruciate substituting-flex (LPS-flex) or gender-specific posterior cruciate substituting-flex (LPS-Flex) total knee prosthesis.

Detailed Description

Recently much debate and discussion has focused on the effect of gender-specific total knee arthroplasty. The purpose of this study was to compare functional and radiographic results, range of motion of the knee, patient satisfaction, femoral component, revision and complication rates in patients receiving either a standard posterior cruciate substituting-flex (LPS-flex) or gender-specific posterior cruciate substituting-flex (LPS-Flex) total knee prosthesis.
