Hi @babette! My mother (now in her 80s) has had 2 TKRs. She is not one for doing PT on her own, and for the first TKR skimped on the exercises unless actually done with a therapist in person. She made an excellent recovery eventually but it took longer than expected due to her recalcitrance with the exercises. For the second TKR, she was much more diligent with the home exercises and made excellent progress, especially for a person in her late 70s. She added aqua therapy for the second TKR, which she could do in her home jacuzzi, and that did wonders to keep her incentivized to keep up with her therapy.
