Fig. 4From: Randomized controlled trial of compressive cryotherapy versus standard cryotherapy after total knee arthroplasty: pain, swelling, range of motion and functional recoverySurvival analysis of the study parameters. The Kaplan-Meier curves are shown for (A) passive flexion of 90°, (B) passive flexion of 110°, (C) active extension lag (AEL) of 20°, (D) active extension lag (AEL) of 5°, (E) knee circumference + 15 cm from the base of the patella and (F) pain at rest.
