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

A Gender-Specific Posterior Cruciate-Substituting High-Flexion Knee Prosthesis Does Not Improve Fit and Function Compared With a Standard Posterior Cruciate-Substituting High-Flexion Knee Prostheis A Prospective, Randomized Study

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.

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.

Inclusion Criteria:

• End-stage osteoarthritis of the knee joint requiring total knee arthroplasty with bilateral disease, in female patients

Exclusion Criteria:

• Male patient
• Inflammatory disease
• patient with other Lower extremity disease which may affect functional outcome
• Neurologic disease effecting patients lower extremity
• Revision surgery
