Summary
Synthetic cartilage implants (SCI) for hallux rigidus show improved patient outcomes and pain scores in short-term follow-up. Reoperation rates are comparable to previous studies, with some patients requiring revision surgery.
Area of Science:
- Orthopedic surgery
- Biomaterials science
- Podiatric medicine
Background:
- Level I studies suggest synthetic cartilage implants (SCI) are effective for hallux rigidus.
- Recent reviews question these promising results.
- This study aims to report patient-reported outcomes and early complications of SCI for hallux rigidus.
Purpose of the Study:
- To evaluate patient-reported outcomes after hydrogel synthetic cartilage implantation for hallux rigidus.
- To document early complications associated with this innovative treatment.
- To contribute data to the limited literature on SCI for hallux rigidus.
Main Methods:
- Retrospective chart review of 54 patients (59 feet) treated with SCI for hallux rigidus between July 2017 and November 2018.
- Data included demographics, radiographic grading, VR-12, FAAM, VAS, satisfaction, and complications.
- Average follow-up was 18.9 months; Level IV, case series.
Main Results:
- Significant improvements observed in VR-12 Physical (6.5 pts), FAAM ADL (17.2 pts), FAAM Sport (27.4 pts), and VAS (18.4 pts) (P < .01).
- Patient satisfaction was high, with 72.5% willing to undergo the procedure again.
- 18.5% of patients required revision surgery, with 7 converted to arthrodesis.
Conclusions:
- Hydrogel SCI for hallux rigidus leads to improved pain and functional outcomes at short-term follow-up.
- Reoperation and fusion rates are comparable to existing literature.
- SCI offers a viable, though not complication-free, alternative for hallux rigidus treatment.
