Long-term efficacy of total SILASTIC implants: a subjective analysis
Summary
Total SILASTIC implant arthroplasty provided long-term pain relief for degenerative joint disease of the first metatarsophalangeal joint. Most patients reported high satisfaction, demonstrating the procedure
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- Degenerative joint disease of the first metatarsophalangeal joint often causes significant pain and functional limitation.
- Total joint arthroplasty using SILASTIC implants was an early surgical option for this condition.
Purpose of the Study:
- To evaluate the long-term efficacy and patient satisfaction of total SILASTIC implant arthroplasty performed before 1986.
- To assess the correlation between radiographic findings and patient outcomes.
Main Methods:
- Retrospective analysis of 50 patients who underwent total SILASTIC implant arthroplasty.
- Subjective questionnaires assessing pain, function, complications, and satisfaction.
- Follow-up averaged 13.4 years.
- Outcomes measured using a modified American Orthopaedic Foot and Ankle Society (AOFAS) rating system.
Main Results:
- 97% of patients reported pain relief.
- Overall success rating was 90.7%, with a mean AOFAS score of 87.3.
- Radiographic deterioration was observed in all implants but did not correlate with patient satisfaction.
Conclusions:
- Total SILASTIC implant arthroplasty is a proven procedure for long-term pain relief in selected patients with first metatarsophalangeal joint degenerative disease.
- Appropriate surgical technique, including joint realignment and soft tissue balancing, is crucial for success.
- Radiographic implant deterioration alone should not be the sole indication for revision surgery.
