Hi all,We have a 50 ish bilateral AKA who is not eligible for MPK due to insurance. He is doing well with bilateral total knees but has issues with stairs, of course. Â PT said he’d never be able to do stairs without MPK but what about bilateral Mauch knees. Those would be covered by insurance. Â Does anyone have experience with bilateral Mauch users on stairs? Â thanksKarl Entenmann, CPOPreferred O and PTacoma WA
