Table 1 Medians, minima and maxima for the distribution of total HHS scores before and four, six, 12 weeks after posterior versus direct lateral THA; medians of the respective intraindividual changes' distributions (post - preoperative); p-values derived from two sample Wilcoxon test at each assessment time, respectively
