Characteristics of People with Hip or Knee Osteoarthritis Deemed Not Yet Ready for Total Joint Arthroplasty at Triage
Bibliographic record
Abstract
PURPOSE: To identify the characteristics of people with hip or knee osteoarthritis (OA) attending a regional triage centre for an initial consult who are deemed not yet ready for total joint arthroplasty (TJA). METHODS: Initial consultation notes (n=482) were reviewed retrospectively. Predictive variables were derived from the literature a priori, and 14 of these variables were suitable for inclusion in stepwise multiple logistic regression analyses. RESULTS: Of the 222 eligible people, 131 (59%) were deemed not yet ready for TJA. Five variables entered into the model ([Formula: see text]=133.19, p<0.001) for an overall success rate of 81.1%. Those deemed not yet ready for TJA were more likely to have knee OA (vs. hip OA; odds ratio [OR]=0.352, p=0.018), to have less severe OA (OR=0.246 for each category increase in severity, p<0.001), to use no gait aid (vs. cane; OR=0.390, p=0.033), and to have a higher Lower Extremity Functional Scale score (OR=1.050 for each 1-point increase, p=0.003) and better joint status as measured by the Knee Society Scale or Hip Harris Scale (OR=3.946 for each category increase, p=0.007). CONCLUSION: Considering these characteristics will help clinicians to identify individuals likely to require interventions other than TJA.

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.
