Fig. 6: Clinical recovery outcome measures between control and MP treatment.

All boxplots show median values, interquartile range, whiskers of 1.5 times interquartile range of clinical recovery parameters (a) pain, (b) fatigue and daily functioning, and (c) functional impairment of the operated hip over the course of 28 days after surgery between control (n = 30 patients) and MP (n = 28 patients) groups (two-sided Wilcoxon rank sum test). Pain and functional impairment of the hip were assessed with an adapted version of the Western Ontario and McMaster Universities Arthritis Index (pain 0 to 40 = none to worst; function 0 to 60 = no to most severe impairment). Postoperative fatigue and daily functioning were assessed with the Surgical Recovery Scale (17 to 100 = worst to none).
