Complications of polycentric knee arthroplasty
Clinical Orthopaedics and Related Research
|January 1, 1976
Summary
This study assessed 89 polycentric knee arthroplasties, finding 81% improved patient mobility. However, complications like infection and loosening occurred in some cases.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Polycentric knee arthroplasty is a surgical procedure to replace the knee joint.
- Assessing long-term outcomes and complications is crucial for patient care.
Purpose of the Study:
- To evaluate the functional outcomes and complication rates of polycentric knee arthroplasties.
- To determine the effectiveness of this implant in improving patient mobility.
Main Methods:
- Retrospective analysis of 89 polycentric knee arthroplasties.
- Follow-up period ranged from 2 to 7.5 years post-operation.
Main Results:
- 81% (72/89) of arthroplasties resulted in improved patient mobility.
- 17 arthroplasties showed no improvement in mobility.
- Complications included infection (7%) and prosthetic component loosening (10%).
- 3 cases of infection required arthrodesis.
Conclusions:
- Polycentric knee arthroplasty demonstrates a high success rate in improving patient mobility.
- Potential complications such as infection and loosening require careful monitoring and management.
