Nausea or vomiting (%)	4/16 (25)	4/17 (24)	0.92
Symptoms of local anesthetic poisoning (%)	0/16 (0)	0/16 (0)	1.00
Satisfaction	4 (1)	4 (1)	0.75
Dose of diclofenac (mg)	0 (25)	25 (25)	0.28
Time until first analgesic usage (hour)	20 (5.4)	18.6 (7.7)	0.59
Hospital stay (days)	25 (7.75)	24 (11.00)	0.69
ROM (extension, temporal change) (degrees)	−8 (11)	−6.9 (10)	0.89
ROM (flexion, temporal change) (degrees)	−6.1 (13)	−6.3 (13)	0.59
KSS (temporal change)	42 (42.5)	49.5 (24.3)	0.86

Data are expressed as the mean (SD), median (interquartile range: value at 75 %–value at 25 %), or n (%) and were compared using the Mann–Whitney U test, Wilcoxon signed-rank test, or chi-squared test. Satisfaction was rated using a five-point evaluation system
