I’ve just finished watching "RICHARD III - THE NEW EVIDENCE (C4) (2014)
This is the documentary which attempts to establish whether a slender young man with scoliosis could ever be a “warrior-king”.
By sheer coincidence, a young man called Dominic Smee lives in Leicestershire, has exactly the same scoliosis as Richard II and is a medieval re-enactor on Bosworth field - he is not, however, a knight.
The producers subject Dominic to all sorts of tests and train him in horsemanship and fighting - he even gets a custom-built suit of armour.
Without giving too much away, I can say that the results of the tests and training defy expectations but the results of the skeletal analysis, which ran alongside, were surprising and significant.
