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

Medical and Biotech [MESH] Definitions
Deltoid Muscle
Thick triangular muscle in the SHOULDER whose function is to abduct, flex, and extend the arm. It is a common site of INTRAMUSCULAR INJECTIONS.
Osteoarthritis, Knee
Noninflammatory degenerative disease of the knee joint consisting of three large categories: conditions that block normal synchronous movement, conditions that produce abnormal pathways of motion, and conditions that cause stress concentration resulting in changes to articular cartilage. (Crenshaw, Campbell's Operative Orthopaedics, 8th ed, p2019)
Gender Identity
A person's concept of self as being male and masculine or female and feminine, or ambivalent, based in part on physical characteristics, parental responses, and psychological and social pressures. It is the internal experience of gender role.
Knee Injuries
Injuries to the knee or the knee joint.
Sex Differentiation Disorders
Abnormalities in the development of the GONADS, the genital tracts, the external GENITALIA, and gender-specific behavior.
