Modular versus all‐polyethylene tibial components: comparison of pre‐ and early post‐operative patient scores in total knee replacement
Bibliographic record
Abstract
INTRODUCTION: All-polyethylene (AP) tibial components of total knee replacement (TKR) are substantially cheaper than their modular counterparts. It is well established that their survivorship and radiographic outcomes are comparable. In this study, patient-derived outcome measures were used to compare these two implant types. METHODS: A cohort of 456 primary TKRs (142 AP, 314 modular) were assessed with preoperative and 1-year post-operative Oxford Knee Score, Western Ontario and McMaster Universities Arthritis Index and Short Form - 12 scores. RESULTS: Both groups performed well with no significant difference in improvement and final scores at 1 year. Although there was a significant difference in mean age among the groups (P < 0.001) age-adjusted scores continued to show no significant difference between the two groups. DISCUSSION: Our results support the more frequent use of AP tibial components for uncomplicated TKR.

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.
