Patients, n (%)	23 (100)	22 (100)
Gender , Female/Male (% female)	16/7 (69.6)	13/9 (59.1)	0.46
Age (yrs), mean (range)	66.6 (47–85)	65.3 (44–82)	0.71
BMI, mean (SD)	29.2 (4.93)	30.0 (6.50)	0.62
Per-op complications, n (%)	0 (0)	0 (0)
Pre-op total ROM, mean (SD)	109.8 (9.94)	115.2 (14.01)	0.14
Pre-op OKS, mean (95% CI)	22.4 (6.76)	22.8 (6.78)	0.85
Pre-op knee circumference, mean (95% CI)	45.8 (3.69)	45.3 (4.67)	0.70

For normally distributed data, in accordance with Shapiro Wilk-test, kurtosis and skewness, mean values are presented, and p-value calculated using the unpaired T-test. P-values for categorical data is calculated using Pearson’s Chi-squared (χ2) test when appropriate
