Summary
Total knee replacement significantly improves function and reduces pain in patients with severe knee impairment. This long-term study shows excellent outcomes regardless of the initial diagnosis, enhancing patient independence.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Total knee replacement (TKR) addresses significant functional limitations in patients.
- Non-constrained total knee prostheses are currently the most utilized implant type.
Purpose of the Study:
- To evaluate the long-term clinical and radiological outcomes of total knee replacement.
- To assess functional recovery and pain reduction following TKR.
Main Methods:
- A cohort of 25 patients (12 RA, 13 osteoarthritis) underwent TKR between 1987-1997.
- Mean patient age at operation was 60 years, with a mean follow-up of 13 years.
- Clinical outcomes were assessed using WOMAC and KSS scores; radiological evaluation examined component positioning and loosening.
Main Results:
- Preoperative KSS averaged 40 and WOMAC 95; post-surgery, KSS improved to 98 and WOMAC to 30.
- All patients reported increased function and decreased pain.
- Radiological assessment confirmed correct component placement and absence of loosening in all cases at final follow-up.
Conclusions:
- Total knee replacement provides durable functional restoration and pain relief, reducing patient dependency.
- The positive outcomes of TKR are consistent irrespective of the underlying diagnosis (RA or osteoarthritis).
