Hope you can get back in the swing Tom, pain sucks, and you've been fighting it a long time. Do you ice it at all?
Had some recovery days myself after doing something to me knee again, back at 100% today and went to task:
Squats 5x5 @205
OHP 4-5x6 @100
Deadlifts 135,225,275,275,225,135x5
I'm going to feel it tomorrow I'm sure, but right now I feel awesome
