Summary
Total ankle joint replacement using the TPR system showed improved pain and function, with average walking distance increasing significantly. However, outcomes were disappointing compared to ankle fusion surgery.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Rheumatoid arthritis and osteoarthritis commonly affect the ankle joint, leading to pain and functional limitations.
- Total ankle joint replacement (TAJR) is a surgical option for end-stage ankle arthritis.
Purpose of the Study:
- To evaluate the clinical outcomes of the TPR total ankle joint replacement system.
- To assess improvements in pain and function following TAJR.
Main Methods:
- A cohort of 25 patients (30 ankles) received the TPR total ankle joint replacement system.
- Twenty-three ankles in 18 patients were followed retrospectively, with an average follow-up of 59 months.
Main Results:
- Significant improvements were observed in pain and function post-surgery.
- Average walking distance increased from 260 m preoperatively to 975 m postoperatively.
- The study included patients with rheumatoid arthritis (21 ankles) and osteoarthritis (2 ankles).
Conclusions:
- The TPR total ankle joint replacement system demonstrated improvements in pain and function.
- However, the overall results were considered disappointing when compared to outcomes reported for ankle arthrodesis (fusion).
