Knee-based exercises were undertaken in supine (active- assisted knee flexion using a bandage, inner range quadriceps contractions, and straight-leg raises), seated (active-assisted knee flexion using the contralateral limb and inner range quadriceps contractions), and standing (hip and knee flexion, active hamstring curls, lunges on a step, hamstring stretches) postures. These exercises were undertaken in sets of 10 repetitions, 3 times daily; the physiotherapist was present to assist, as required, on 2 occasions per day for the first 3 postoperative days and then once daily from day 4 until hospital discharge.
