| Summary: | Category: Midfoot/Forefoot Introduction/Purpose: Previous studies show mixed results for the use of a hydrogel synthetic cartilage implant (SCI) for the treatment of hallux rigidus. Independent retrospective reviews have put results into question with respect to outcomes and reproducibility. The purpose of this article is to report modification of patient-selection, implantation technique and postoperative protocols. Which may be necessary to improve patient outcomes. Methods: This was a retrospective chart review of patients undergoing hydrogel synthetic cartilage implant for the treatment of hallux rigidus from 2017 to 2021. Data collected included patient demographics, radiographic grading/alignment, and outcomes with respect to revision rate and complications. 50 patients, with an average age of (range,) years were analyzed. The average latest follow-up was (range,) months. None were diabetic or smokers. Results: All patients reported improvement upon follow-up, except 2 that reported continued stiffness and occasional pain. No patients required revision or adjuvant procedures to date. There were no infections or related complications. Conclusion: Modification of patient-selection, implantation technique and postoperative protocols should be considered for synthetic cartilage implantation for the treatment of hallux rigidus. In this review improved pain and outcomes at short and long term follow up were demonstrated. There were no reoperations, infections or conversions to fusions. With only two patients experiencing stiffens.
