Summary
Asian patients undergoing total knee arthroplasty reported significantly lower preoperative knee function than Caucasian patients. Understanding cultural factors is key to optimizing surgical outcomes and patient education.
Area of Science:
- Orthopedics
- Arthroplasty
- Health Disparities
Background:
- Osteoarthritis prevalence is high across diverse populations.
- Preoperative functional status significantly impacts total knee arthroplasty outcomes.
- Ethnic variations in preoperative function may influence surgical success.
Purpose of the Study:
- To compare preoperative knee function between Asian and Caucasian patients undergoing total knee arthroplasty.
- To identify potential disparities in functional status prior to knee replacement surgery.
Main Methods:
- Prospective study design.
- Inclusion of 63 Asian and 63 age/gender-matched Caucasian patients.
- Assessment of preoperative knee function using the Knee Society Clinical Rating System.
Main Results:
- No statistically significant difference in mean preoperative knee score between Asian (37.6) and Caucasian (41.5) patients (p<0.12).
- Highly statistically significant difference in mean preoperative knee function score, with Asian patients scoring lower (32.5) than Caucasians (45.0) (p<0.00015).
Conclusions:
- Asian patients exhibit significantly lower preoperative knee function compared to Caucasians before total knee arthroplasty.
- Cultural beliefs and social support may contribute to functional disparities.
- Healthcare providers should emphasize patient and family education on optimal surgical timing for enhanced benefits.
