J-MAP: Joint-Specific Multidimensional Assessment of Pain; WOMAC: Western Ontario Western Ontario and McMaster Universities Osteoarthritis Index; SKIP: Satisfaction with Knee Procedure; SF12 PCS: Physical Component Summary; SF12 MCS: Mental Component Summary; VAS: Visual Analogue Scale; TUG: Timed Get Up and Go; ROM: Range of Motion
Improvement is seen as positive differences for SKIP; SF12 PCS, MCS, and ROM, and negative differences for J-MAP, WOMAC and TUG
P values for repeated measures models testing for difference in means across time excluding waiting list group
P values including waiting list group
statistically significant (p<= 0.05).
