For the first few week I always elevated at night while trying to sleep. Then in the morning the dreded stiffness, maybe 85 degrees at best. I would have my morning coffee, then start working the knee with the rubber band, wool sock and floor. The Physical Therapy folks should have different color rubber straps or bands, I started out with a red, then green and finally graduated to a black, black being the most strongest or least stretchable. I would wrap the band around the arch of my foot or toes, sit on the edge of a couch with a wool sock on the surgical leg, slide the foot forward and back, pulling back the most important holding the stretch for about ten seconds, slide forward and repeat gain nd again. The objective was to get the knee to flex while pulling inward just to the point where it became lightly uncomfortable, hold for 10 seconds and repeat. The only purpose for the wool sock is to prevent friction while sliding the surgical foot on the wood floor surface. There is a video on google of this excersise. I hope thi helps, I know it did for me.
