Abstract
Contralateral joint osteoarthritis (OA) was found in 86.7% of unicompartmental knee arthroplasty patients, 90.4% of total knee arthroplasty patients, and 70.4% of total hip arthroplasty patients.
- A high prevalence of contralateral joint OA was observed across Asian, Native Hawaiian/Pacific Islander, and White patients undergoing knee or hip arthroplasties.
- Concurrent hip OA was present in 41.6% of unicompartmental knee arthroplasty and 59.5% of total knee arthroplasty patients.
- No significant racial differences in contralateral knee OA prevalence were found among knee arthroplasty patients.
- White patients exhibited a higher prevalence of contralateral hip OA (74.6%) compared to Asians (66.5%) among total hip arthroplasty recipients.
- Increased age and body mass index were significantly linked to the presence of contralateral knee OA.
- Factors such as increased age, male sex, and being White were significant contributors to the prevalence of contralateral hip OA.
