Green represents adequate properties, yellow represents mixed fi ndings, and red represents inade-
quate properties. Please note that properties are specifi c for the context in which they have been
determined. Acceptable test–retest reliability (column 5) refers to values for use in individuals
(ICC ≥0.9). Mixed or inadequate fi ndings for test–retest reliability (column 5) were found for most
instruments. Clinicians can use minimal detectable change (MDC) or smallest detectable difference
(SDD) values to determine whether an individual patient’s scores represent a real change. Where
available, these are provided in the text for each PROM. Several instruments have high fl oor/ceil-
ing effects (column 7 and 8) seen prior to and following total joint replacement (TJR). Considering
that TJR is appropriate for advanced stages of OA, it is as expected that >15 % would report worst
possible pain/function, and, considering the good clinical treatment effect from TJR, it is to be
expected that >15 % report no pain/no functional limitations postoperatively. While clinicians
should be aware of the fl oor and ceiling effects >15 % from TJR common in many measures of pain
and function, it should not preclude evaluation of pain and function by PROMs in TJR
ADL , activities of daily living; OA , osteoarthritis; VAS , visual analogue scale; QoL , quality of life;
HTO , high tibial osteotomy; TKR , total knee replacement; THR , total hip replacement; ?, no data
available; n/a, not applicable

For fl oor and ceiling effects, a white box with red highlighting indicates that data is only available

for total joint replacement, and that inadequate properties are specifi c to total joint replacement.
Data is not available for nonsurgical OA populations
Harris Hip Score and modifi ed Harris Hip Score are not reported as their measurement properties
