Table IV.

Difference in requirements for knee balancing procedures during total knee arthroplasty using either mechanical alignment (MA) or kinematic alignment techniques.

Knee balancing intervention	MA, n (%); n = 68	KA, n (%); n = 70	p-value
Type of knee balancing intervention
Patients requiring soft-tissue releases only	11 (16)	16 (23)	0.439†
Patients requiring bone recuts only	18 (26)	1 (1)	< 0.001* †
Patients requiring both bone recuts and soft-tissue releases	15 (22)	5 (7)	0.013* †
Proportion of bone recuts
Patients requiring any bone cuts	33 (49)	6 (9)	< 0.001* †
Tibial recuts only	24 (35)	4 (6)	< 0.001* †
Femoral recuts only	5 (7)	2 (3)	0.271‡
Both tibial and femoral recuts	4 (6)	0 (0)	0.056‡
