I agree with the other poster saying to look at everything else you're doing as well. My knee hurt for a few weeks starting a few days after moving house. Look into hand exercises. Rock climbing (especially bouldering) can help if you're up for it / live by a rock gym or somewhere lucky enough to have good outdoor climbing. The Microsoft Sculpt keyboard and mouse are the best I've found ergo-wise. imovr makes desks with solid keyboard platforms which can tilt to pretty extreme negative angles if you find that that helps as well. The sculpt KB comes with a negative angle riser as well, to get a feel for if you like that type of thing.
