Unicompartmental knee arthroplasty following patellectomy
Clinical Orthopaedics and Related Research
|May 1, 1987
Summary
Total knee arthroplasty after patellectomy can cause pain. The Marmor knee prosthesis demonstrated excellent or good outcomes in 10 patients over a nine-year follow-up, highlighting the importance of cruciate ligament preservation.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
Background:
- Total knee arthroplasty (TKA) following patellectomy is associated with patient pain and instability.
- Previous TKA designs may not adequately address the biomechanical challenges post-patellectomy.
Purpose of the Study:
- To evaluate the clinical outcomes of the Marmor knee prosthesis in patients who have undergone patellectomy.
- To assess the long-term efficacy of this specific prosthesis in managing post-patellectomy knee issues.
Main Methods:
- Retrospective analysis of 11 Marmor knee arthroplasties in 10 patients.
- Average follow-up duration of nine years.
- Clinical outcome assessment based on patient-reported pain and stability.
Main Results:
- Seven out of ten patients achieved excellent outcomes.
- Three out of ten patients achieved good outcomes.
- No mention of revision surgeries or significant complications in the provided abstract.
Conclusions:
- The Marmor knee prosthesis shows promising results for patients with total knee arthroplasty after patellectomy.
- Preservation of cruciate ligaments or use of prostheses with inherent anteroposterior stability is crucial for successful outcomes.
