Unisex total knee prosthesis: gender and therapeutic effects

Abstract

Abstract:

BACKGROUND: There were certain differences in the anatomical structure of knee joint between man and woman. Gender knee solution is a new type of artificial knee joint prosthesis, which is specially designed for women. Theoretically, the outcome of unisex total knee arthroplasty prosthesis should be related to gender, but we did not find very obvious differences in practical clinical work.
OBJECTIVE: To analyze the differences in curative effects of the unisex knee arthroplasty prosthesis between male and female patients undergoing total knee arthroplasty so as to find out if it is necessary to apply female knee prosthesis among appropriate crowd.
METHODS: We retrospectively analyzed the clinical data of patients undergoing total knee arthroplasty from May 2001 to June 2011. Among 312 patients (350 knees receiving total knee arthroplasty), patients who died within 3 years after surgery, lost to follow-up and underwent revision were excluded. Changes in knee functions and
imaging were observed between males and females.
RESULTS AND CONCLUSION: The women and men had similar mean pre-operative knee scores, flexion function, pain score among 285 patients (300 knees). However, the women had significantly lower mean extension function and function scores than the men. There were no significant differences in improvement in the knee scores, flexion, the pain and knee function between women and men before and after surgery. Nevertheless, men had better extension than women. No significant difference in radiolucencies and complications was seen between females and males. Therefore, there was little difference in outcomes between women and men who used the unisex total knee arthroplasty prosthesis.
