4 years ago my left knee was operated on – MPFL reconstruction. I couldn’t weight bear for a month and had a hinges splint for 3 months. I couldn’t cycle for a year.
There are still things I can’t do, but plenty I’ve adapted:
I can’t row but I can kayak, I can’t run but I can speed walk. I changed body combat to Zumba gold and now adjust Zumba fitness. It takes time but it’s possible to come back and do even more.
