Summary
Attenborough knee replacements show a high complication rate, including wound infections, patellar fractures, and component loosening. Further surgery was often needed for patellofemoral pain when the patella was not resurfaced.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
Background:
- Total knee replacement (TKR) is a common procedure for end-stage knee arthritis.
- The Attenborough knee prosthesis is a specific implant design used in TKR.
- Post-operative complications can significantly impact patient outcomes and implant longevity.
Purpose of the Study:
- To evaluate the incidence of complications following Attenborough knee replacement.
- To assess the long-term outcomes and revision rates associated with this implant.
Main Methods:
- A retrospective review of 144 consecutive Attenborough knee replacement surgeries.
- Clinical and radiographic re-examination of 107 patients between 2 and 6 years post-operation.
- Detailed analysis of complication types, including wound issues, patellar problems, and component loosening.
Main Results:
- A high overall complication rate was observed in the re-examined cohort.
- Wound problems occurred frequently, with four cases progressing to deep infection.
- Patellar resurfacing led to a 17.5% fracture rate, while non-resurfacing resulted in 16% requiring further surgery for patellofemoral pain.
- Definite loosening of major components was identified in 10% of cases.
Conclusions:
- The Attenborough knee replacement is associated with a significant incidence of complications.
- Both patellar resurfacing and non-resurfacing strategies present distinct risks.
- Component loosening is a notable concern, suggesting potential long-term challenges with this implant design.
