Pain and dysfunction change between 6 weeks and 6 months post-TKA (positive scores indicate improvement).

	None-mild pain (≤ 7) at both time points	Worsened (none-mild pain to mod-severe pain)	Mod-severe pain (> 7) at both time points	Improved (mod – severe pain to none-mild pain)

Mean change score (SD)	1.12 (2.23)	−5.65 (2.94)	1.19 (4.30)	7.80 (2.62)
Minimum	−5.50	−11.50	−11.00	3.50
Maximum	6.50	−2.00	7.50	17.00

	None-mild dysfunction (≥75) at both time points	Worsened (none-mild dysfunction to mod-severe dysfunction)	Mod-severe dysfunction (<75) at both time points	Improved (mod – severe dysfunction to none-mild dysfunction)
n (%)	99 (47%)	10 (5%)	39 (18%)	64 (30%)
Mean change score(SD)	6.14 (7.53)	−28.08 (22.45)	2.21 (12.20)	20.87 (9.20)
