Purpose:
The purpose of this study is to evaluate the effect of gender on functional outcomes in Asian patients undergoing conventional total knee arthroplasty (TKA).
Patients And Methods:
A review of 217 patients who underwent primary total knee arthroplasty by a single surgeon was conducted. Postoperative range of motion, Knee Society Score, Oxford Knee Score and Short Form-36 Physical Component Score (PCS) and Mental Component Score (MCS) were collected prospectively in all patients at both 6 months and 2 years following conventional TKA. The patients were then stratified based on gender and their outcomes were compared using Student's t-test.
Results:
Preoperatively, the females had a significantly poorer flexion range as compared to the males. Postoperatively at 6 months and 2 years following conventional TKA, both groups showed improvement from their preoperative range of motion and scores and had no significant differences in outcomes.
Conclusion:
Similar to several studies in the Western literature, gender does not seem to affect short-term outcomes in Asian patients undergoing TKA. Longer-term data on survivorship and outcomes are needed before routine use of gender-specific TKA can be recommended.
