Comparison of Functional Outcome of Total and Unicompartmental Knee Arthroplasty Using Computer-Assisted Patient-Specific Templating

Table 3

Comparison of the difference between the postoperative and preoperative values of Knee Society Score, functional knee score, and the range of flexion in the two groups.

	Group 1 (TKA)			Group 2 (UKA)			value
	N = 18			N = 19
	Mean difference	SD	SE	Mean difference	SD	SE
KSS	39.35	7.74	1.73	31.20	5.08	1.14	0.003
FKS	32.00	8.18	1.83	31.75	8.93	2.00	0.926
ROF	10.25	4.72	1.06	7.25	5.50	1.23	0.072

TKA, total knee arthroplasty; UKA, unicompartmental knee arthroplasty; KSS, Knee Society Score; FKSS, functional knee score; ROF, range of flexion; SD, standard deviation; SE, standard of error.
