Total hip arthroplasty for failed endoprostheses
Clinical Orthopaedics and Related Research
|November 1, 1978
Summary
Revision total hip arthroplasty using the Charnley prosthesis effectively treats failed hip endoprostheses, significantly improving pain and ambulation. Early intervention with debridement and antibiotics is crucial for managing low-grade infections post-revision.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Failed hip endoprostheses present a significant challenge in orthopedic surgery.
- Revision arthroplasty is a common procedure to address complications of primary hip replacements.
Purpose of the Study:
- To evaluate the outcomes of Charnley total hip arthroplasty for failed hip endoprostheses.
- To assess the efficacy of revision surgery in improving patient function and alleviating pain.
Main Methods:
- Ninety Charnley total hip arthroplasties were performed in 80 patients between July 1970 and November 1975.
- Patients had previously failed endoprostheses requiring revision surgery.
Main Results:
- Pain was alleviated or minimal in 97.7% of cases.
- Ambulatory function improved in all patients, with 93.2% achieving good or excellent results.
- Low-grade infection was identified as a factor to consider in failed endoprostheses.
Conclusions:
- Revision total hip arthroplasty with the Charnley prosthesis yields high success rates for failed endoprostheses.
- Surgical debridement and antibiotic therapy are effective in managing low-grade infections associated with failed hip implants.
- This procedure significantly enhances patient quality of life by restoring pain relief and mobility.
