^*Values are mean ± SD, unless indicated otherwise, measured at the actual examinations in people with incident knee osteoarthritis, defined up to the 30-month visit. Crude data: original values, including unadjusted pre-TKR values but no post-TKR values. Adjusted data: original values with imputed missing values and adjusted pre-TKR values. Higher values indicate worse function. MOST = Multicenter Osteoarthritis Study; WOMAC-PF = Western Ontario and McMaster Universities Osteoarthritis Index physical function.

^†Linear trend over time from 30 to 84 months.

^‡Measured in seconds.
