Fixed-Bearing, Medial Unicondylar Knee Arthroplasty Rapidly Improves Function and Decreases Pain –<i>A Prospective, Single-Surgeon Outcomes Study</i>
Bibliographic record
Abstract
Fixed-bearing, medial unicondylar knee arthroplasties were performed in 33 knees (32 patients). We report a minimum 2-year follow-up, with a mean follow-up of 3 years. Kaplan-Meier survivorship analysis reported 97% survivorship at a mean follow-up of 38 months. Average preoperative Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores improved significantly from 40+/-22 to 92+/-15 (P<.0001). Average preoperative Knee Society knee and function scores improved significantly from 52+/-7 to 90+/-9 (P<.0001) and from 48+/-16 to 84+/-17 (P<.0001), respectively. In addition, average Short Form-12 Physical Component scores significantly increased. Overall stiffness and physical function assessed via the WOMAC index also exhibited significant improvement. Of note, all categories of the WOMAC Index and the Knee Society scores experienced statistically significant improvements at 3-month follow-up, indicating a rapid return to improved function and diminished pain.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
