At 15 months post op I still do all the exercises for my new knee as prescribed by my physical therapist! Includes things like stationary bike, strengthening with exercise ankle weights one and two pounders. Rolling down right left of knee with rolling pin center knee done with hands. Other leg strengthening exercises, squats, balancing and endurance exercises 3 times a week. At 65 will keep them up as long as I can. My new knee is awesome!!!
My therapist made sure I didn’t develop and scar tissue using deep tissue massaging which is not fun but I know necessary and taught me the art of using rolling pin which I do to this day. A lot of time and work for me but to date my knee has been awesome!!!
