Dr. HFWR I'm not, but as we've discussed in many previous threads, it's difficult to out-exercise a "bad" diet, in this case "bad" being too many calories for a given metabolism and/or activity level. And gimpy knees make being active a bit more difficult...
Still, using some upper body compound lifts will get your heart pumping. I stick to chest presses, lat pulldowns, shoulder presses, and seated rows, rather than isolating stuff, like curls. Your arms will get a good workout doing the compound machines. And the creaky knees get a break. I'd let the PT decide what is appropriate for the knees, both pre-and post-surgery.
As for the diet, I'd start with calculating what calorie level you'd need to maintain your "ideal" weight (how much would you like to weigh?), and try to maintain that level. Low carb might be indicated as well, given the relatively low level of activity from being gimpy...
And I "highly" recommend medicinal marijuana...
