Summary
Mobile-bearing total knee replacements show excellent long-term survival rates. This study confirms their effectiveness and improved patient function over 10-18 years.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Clinical orthopedics
Background:
- Mobile-bearing knee designs offer an alternative to fixed-bearing implants in total knee arthroplasty.
- Evaluating the clinical outcomes of mobile-bearing knee implants is crucial for surgical decision-making.
Purpose of the Study:
- To determine the clinical results and long-term survivorship of a mobile-bearing total knee prosthesis.
Main Methods:
- A consecutive series of 326 mobile-bearing total knee prostheses were implanted between 1990 and 1998.
- Patients were evaluated using the Knee Society clinical rating system and radiographic examinations, with complications and survivorship noted.
Main Results:
- Mean follow-up was 156 months, with a maximum of 18 years.
- Significant improvements were observed in Knee Society knee and functional scores, as well as knee flexion (p=0.00).
- The 10-year survival rate was 0.96, and the 18-year survival rate was 0.87, with 7.4% of knees requiring revision.
Conclusions:
- Fully congruent mobile-bearing total knee prostheses demonstrate excellent survivorship.
- These implants provide durable clinical results and improved function over a long follow-up period.
