Table 2.

Correlations between the change in functional measures (TUG, SCT, 6MW) and change in self report (HOOS ADL and Pain subscales) measures from the preoperative time point to one month postoperative and from one month to six months postoperative. Abbreviations: HOOS=Hip dysfunction and Osteoarthritis Outcome Score; ADL=Activities of Daily Living; TUG=Timed up and Go; SCT=stair climb test; 6MW= Six minute walk.
