I can run 5km no problem, do a high intensity workout now

Just wanted to say a massive thank you for all you did for me with my left knee allograft. I have 2 beautiful boys who I am playing sport with. I can run 5km no problem, do a high intensity insanity workout whenever I want. I surf and play a bit of beach volleyball ( although my knee doesn't like it) so i just jump in a brace 2 days and i am fine again. I work full time as a physiotherapist and stood 10hrs a day in the CPAP wards, it's to support the covid outbreak over several months.
I couldn't have done any of this without the dream team of you both, so thank you.
