Honestly mate I wouldn't bother I have had a knee reco and played Aussie rules 9 mths after getting my reco, most recommend 12 mths....
all I took maybe was protein powder, however, I pushed myself every time I did anything for rehab, I was only on crutches for 1 wk, then I was constantly trying to bend the knee to get it moving, once I could walk I was walking everywhere and often, yes it did swell but i lso rwsted it and iced regularly after exercise, once it was strong enough i was pushing it on a stationary bike and joggin as well till it was nice and strong as well as leg press, calf raises, leg curls etc etc
So you can do it without Supps and i don't think they re needed for this type of injury and surgery...
