Abstract
ABSTRACT Osteoarthritis (OA) is a prevalent degenerative joint disease primarily affecting hip and knee joints, with an estimated 300 million cases globally. This study is crucial as it provides an updated, comprehensive comparison of unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) for treating medial knee osteoarthritis, offering valuable insights into their relative effectiveness. The findings aim to inform clinical decision‐making and improve patient outcomes by identifying the superior treatment option. A comprehensive search was conducted across PubMed, Cochrane Library, and Google Scholar until August 1, 2024. Statistical analysis used Review Manager 5.4 with a random‐effects model, risk ratio (RR), and mean differences (MD) with 95% confidence intervals (CI) for the dichotomous and continuous outcomes, respectively. The Newcastle‐Ottawa Scale was used for quality assessment, and funnel plots were used to analyze publication bias. GRADE assessment was done to gauge the certainty of the evidence. Thirty‐nine studies, involving a total of 56,686 patients, were evaluated for comparison. UKA significantly reduced the complications (RR = 0.37; 95% CI: [0.25, 0.54]; p < 0.0001; I 2 = 30%), revision rates to total knee arthroplasty (TKA) (RR = 0.64; 95% CI: [0.41, 0.99]; p = 0.05; I 2 = 72%) and postoperative pain (MD = −0.33; 95% CI: [−0.64, −0.03]; p = 0.03; I 2 = 89%) compared to HTO, while range of motion (ROM) (RR = −3.55; 95% CI: [−7.16, 0.52]; p = 0.09; I 2 = 98%) and walking speed (MD = 0.02; 95% CI: [−0.04, 0.07]; p = 0.56; I 2 = 0%) and surgical site infections(RR = 1.40; 95% CI: [0.30, 6.53]; p = 0.67; I 2 = 86%) were comparable. All the functional knee scores are comparable except the Hospital for Special Surgery (HSS) score, which is increased in UKA (MD = 2.63; 95% CI: [0.52, 4.74]; p = 0.01; I 2 = 76%). UKA is superior to HTO, offering lower revision rates, reduced postoperative pain, fewer complications, and better functional scores.

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 it
