Unfortunately, now that I think of it, all the therapists I know are Project boys (and girls). Shouldn't be too difficult to get yourself referred to someone, though.
Since you can heal yourself, you might just try keeping the juice flowing as much as you can. That might be pretty exhausting, but, over time, it would probably stimulate tissue regeneration enough to bring your knee up to your physical norm.
