One-year Oxford knee scores should be used in preference to 6-month scores when assessing the outcome of total knee arthroplasty

Table 4 Independent predictors of a MCID in the improvement in the OKS from 6 to 12 months after TKA

Demographic	Descriptive	Odds ratio	95% CI	P value
BMI	For each BMI point	0.97	0.94 to 0.99	0.028
Comorbidity	Not present	Reference*
Comorbidity	Diabetes mellitus	0.61	0.39 to 0.96	< 0.001
Functional measure
OKS	Preoperative	1.05	1.02 to 1.07	< 0.001
OKS	6 Months	0.91	0.89 to 0.92	< 0.001

Logistic regression analysis: entering all variables into the model (Table 1) using forward conditional methodology. The R² value of the model was 0.10
MCID minimal clinically important difference, OKS Oxford Knee Score, TKA total knee arthroplasty, BMI body mass index, CI confidence interval
*Odds ratio relative to a patient without the stated comorbidity
