Hi @mercuryrose, One of the best things that helped me with my knee replacement a few years ago was the pre-surgery exercises recommended by my surgeon. I think it made my rehab go much smoother and helped with the exercises after the surgery. Here's a list of the ones I focused on – https://www.allinahealth.org/health-conditions-and-treatments/health-library/patient-education/total-knee-replacement/preparing-for-surgery/before-surgery-knee-exercises

Hoping all goes well for your upcoming knee replacement.
