Summary
Cemented total articular replacement arthroplasty (TARA) hip resurfacing showed an 84.5% survival rate at ten years. Younger patients (55.7 years) had higher revision rates, suggesting TARA is less durable than traditional hip replacements.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- Total articular replacement arthroplasty (TARA) is a hip resurfacing technique.
- Cemented fixation is commonly used in hip arthroplasty.
Purpose of the Study:
- To evaluate the long-term outcomes of cemented primary TARA hip resurfacing.
- To compare the survival rates and revision causes of TARA hip replacements.
Main Methods:
- Retrospective review of 184 cemented primary TARA hip procedures performed between 1981-1985.
- Follow-up of 174 hips for a mean of 8 years (range, 3.5-10.4 years).
- Survival analysis using Kaplan-Meier curves.
Main Results:
- Implant failure requiring revision occurred in 13.2% of patients.
- The revised group was significantly younger at implantation (55.7 vs. 65.3 years, p < 0.01).
- Ten-year survival rate was 84.5%, with 87.1% at seven years.
Conclusions:
- Cemented TARA hip replacement demonstrates better intermediate-to long-term success than other cemented resurfacing designs.
- However, TARA longevity does not favorably compare with cemented Charnley total hip replacements at similar intervals.
