Table 3. Significant Predictors of Good UKA Outcome at 5 Years (MCID Criterion).

Predictor	OR	95% CI	p-value
Preoperative Oxford Knee Score (per 1-point increase in score)*	1.27	1.13–1.29	< 0.001
Preoperative SF-36 Physical Component Score (per 1-point decrease in score)	1.08	1.04–1.09	< 0.001
Preoperative Knee Society Knee Score (per 1-point decrease in score)	1.02	1.00–1.04	< 0.001
Preoperative SF-36 Mental Component Score (per 1-point increase in score)	1.02	1.00–1.04	< 0.001

UKA: unicompartmental knee arthroplasty, MCID: minimal clinically important difference, OR: odds ratio, CI: confidence interval, SF-36: Short Form 36.

^*Explanatory note: this means that every 1 point increase (worsening) in Oxford Knee Score is associated with 1.27 higher odds of achieving the MCID for Oxford Knee Score at 5 years following UKA.
