Revision of Synthetic Cartilage Implant Hemiarthroplasty of the Great Toe to Metatarsophalangeal Joint Arthrodesis: Technique and Indications
Bibliographic record
Abstract
The use of a polyvinyl alcohol hydrogel synthetic cartilage implant hemiarthroplasty for osteoarthritis of the first metatarsophalangeal joint has increased since publication of the results of a pivotal, prospective, randomized, multicenter, noninferiority, clinical trial performed in the United Kingdom and Canada. The synthetic cartilage implant was awarded FDA approval in July 2016, permitting its commercial distribution in the United States, which has led to a notable escalation in its use. Concomitant failures in a small proportion of these patients will require conversion to arthrodesis. This study describes the surgical technique used to convert synthetic cartilage implant hemiarthroplasty of the first metatarsophalangeal joint to arthrodesis and the 3 cases that underwent revision at a single center in the United Kingdom. Level of Evidence: Diagnostic Level IV, case series. See Instructions for Authors for a complete description of levels of evidence.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
