Table 4 Patient-reported outcome measures¹

		Mean KOOS, JR (SD)	P value
Preoperative	n = 63	42.8 (18.0)
Six months	n = 73	60.6 (14.4)
Two years	n = 57	70.8 (19.1)
Δ Preop to six months	n = 61	17.4 (18.9)	< 0.001
Δ Preop to two years	n = 46	26.1 (19.7)	< 0.001

¹Variations in n due to differences in patient follow-up and availability of patient-reported outcome measures.

KOOS, JR: Knee Injury and Osteoarthritis Outcome Score for Joint Replacement; SD: Standard deviation; Δ Preop: Difference between pre- and postoperative scores.
