Total articular replacement arthroplasty. A clinical review
Clinical Orthopaedics and Related Research
|May 1, 1984
Summary
Total articular replacement arthroplasty offers significant pain relief and improved mobility for patients. While radiolucency and bone sclerosis were observed, the procedure showed better outcomes than conservative or resurfacing devices over two years.
Area of Science:
- Orthopedic surgery
- Biomaterials science
Background:
- Total articular replacement arthroplasty is a surgical procedure aimed at restoring joint function.
- Evaluating the long-term efficacy and potential complications of this arthroplasty is crucial for patient outcomes.
Observation:
- Sixty-four total articular replacement arthroplasties were performed in 60 patients, with a mean follow-up of 24 months.
- Radiographic analysis revealed a high incidence of progressive radiolucency at the bone-cement interface in the acetabular region.
- Progressive bone sclerosis was noted along the lateral border of the prosthetic stem, suggesting stress transfer adaptations.
Findings:
- Ninety-three percent of patients reported minimal to no pain post-surgery.
- Eighty-three percent achieved unlimited walking ability.
- Ninety-seven percent demonstrated a postoperative flexion of 90 degrees or greater.
Implications:
- Despite observed bone-cement interface issues and stress-related bone changes, total articular replacement arthroplasty demonstrates superior short-term results compared to conservative or resurfacing alternatives.
- Further research into mitigating radiolucency and optimizing stress transfer is warranted to enhance long-term implant survival.
