Table V.

Intercompartmental pressure differences between the manual balance and sensor balance groups at 10°, 45° and 90° of knee flexion.

Knee flexion	Mean ICPD, psi (SD)		p-value*
	Manual balance	Sensor balance
10°	19.9 (17.3)†	7.6 (6.8)	< 0.001
45°	15.7 (13.9)†	8.5 (9.1)	< 0.001
90°	12.2 (8.8)	8.4 (6.8)	< 0.001

^*Independent-samples t-test.

^†Mean ICPDs ≥ 15 psi were defined as “unbalanced”.

ICPD, intercompartmental pressure difference; psi, pounds per square inch; SD, standard deviation.
