Taux de survie et complications d'une prothèse de genou charnière rotatoire avec cône morse spécifique, résultats précoces : une étude de cohorte rétrospective
Bibliographic record
Abstract
Background: indications for rotating hinge total knee arthroplasty concerns both primary and revision surgeries. Despite technological advances since the 1950s, TKA hinge exhibits a high complication rate. This study aims to evaluate the early radiological survival and clinical results of a new rotating hinge with a minimum two-year post-operative follow-up, and to record the occurrence of complications specific to the implant and its design.Methods: a retrospective study was carried out on 26 patients (25 knees) two years post-operatively after the implantation of a TKA hinge (MULTIGEN PLUS®) from LIMA®. 88.5% were indications for prosthesis revision. Follow-up radiographs were taken at each follow-up visit to track loosening and specific implant-related complications. The Western Ontario and McMaster Osteoarthritis index (WOMAC) and the Oxford Knee Score (OKS) were collected retrospectively and at the last follow-up visit.Results: results show an implant survival of 73% at 2 years, with 7 loosenings leading to revision surgery. Significant improvement in WOMAC and OKS scores. No implant-specific complications were observed. Conclusion: the results indicate an appropriate hinge design but suffering from poor survival inprosthesis revision for infection cases. The clinical results are good despite the comorbidfactors of the study population.

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.
