Comparison of Function and Fit of Standard and Gender-Specific CR High-Flex Total Knee Prostheses

Comparison of Function and Fit of Standard Posterior Cruciate-Retaining High-Flexion and Gender-Specific Posterior Cruciate-Retaining High-Flexion Total Knee Prostheses A Prospective, Randomized Study

The purpose of this prospective, randomized study was to compare functional outcome, radiographic results, range of motion, patients satisfaction, and fit of the femoral component in patients receiving either a standard posterior cruciate-retaining high-flexion (CR-flex) and gender-specific CR-flex total knee prostheses.

The design features of the gender-specific knee prostheses have been claimed to improve fit and function of total knee arthroplasty in women. The purpose of this prospective, randomized study was to compare functional outcome, radiographic results, range of motion, patients satisfaction, and fit of the femoral component in patients receiving either a standard posterior cruciate-retaining high-flexion (CR-flex) and gender-specific CR-flex total knee prostheses.

Inclusion Criteria:

• End stage osteoarthritis of the knee joint who require total knee arthroplasty with bilateral lesions.

Exclusion Criteria:

• Inflammatory arthritis
• Osteoarthritis effecting hip joint
• Traumatic arthritis
• Neurologic disorders affecting motor function of lower extremity
• foot and ankle disorders limiting ambulation of the patient
