People-like-me reference charts for a single patient for the (A) Timed Up and Go (TUG) test and (B) Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index. Similar previous patients were identified on the basis of preoperative status. The green line illustrates outcomes monitoring for a hypothetical patient. A deviation in the TUG trajectory is noted at the 8-week visit (arrow). For the purposes of the example in this Perspective, deidentified outcomes data (collected in routine practice at ATI Therapy, Greenville, SC) were accessed retroactively for the TUG test and the WOMAC Osteoarthritis Index.
