Off the top of my head Knowledge Warden: Master grants Skill Focus (choose one).
Even though Skilled Surgeon says you need Skill Focus (Heal) remember you need to pick a focus for your knowledge like Heal (Disease).
As a side bar Knowledge Warden: Master says that it makes Monster Lore no longer a limited Talent, which might be a mistake.

Knowledge Warden
Master
Requirements: Knowledge Warden: Initiate (pa)
Trained Skills: Ranged (Marksman) and any two Lore skills of your choice
Talents Exploit Weakness, Skill Focus (choose one) or Monster Lore (choose one)
Special (Access): Monster Lore is no longer a limited talent for you.
But Monster Lore isn't Limited in the first place. I think it might mean Skill Focus.
