Dr Dave? He only goes by one name, must be a celebrity lol.
Hope it goes well mate. Dave isnt the butcher i know of so all should go well.
My big advice in your recovery is to listen to your knee. The physio will get you to push it a lot, and to a degree you need to do that, but from my experience, listening to your knee works best. My first opp i pushed it hard, and the physios pushed me hard….my recovery was very slow and painful. With my 2nd opp, i did my own physio (cos i knew what was allowed and what wasnt) and mate, i recovered so much quicker it wasnt funny. When i needed to rest i did, when i needed to work it i did. Stretching, ice and anti flammatory's when resting and you'll be fine.
Good luck.
