Just back from the hospital, after an entertaining afternoon in N&N Orthopedics.
Went via X-ray to see a very nice consultant who didn't pull a face when I mentioned "I was 200km into a 600km bike ride when my knee suddenly started hurting."
After examinations and various pushing and pulling my leg, and testing various degrees of motion, he was happy that (a) my ACL was working just fine, (b) there is no fluid now and (c) my quads are well balanced wrt to my patella.
He suggested we could probably find out what had happened from an MRI, and he was happy to put me forward for one - my choice - but he was also happy that nothing had happened that my body had subsequently been unable to reverse or repair, which discounted ruptured ACL or torn cartilage.
We discussed the X-ray; the only thing of any note on there was a very slight narrowing of the spaces between the bones "consistent with an active person of your age" to quote him directly.
In the end, I declined the MRI. He asked if I was unable to do anything I was able to do before, or was avoiding anything. I mentioned that I was taking it easier on the bike, and not using a fixed gear bike for long or hilly rides because of the extra loads. He thought that was reasonable.
There was an open invite to go back should the situation change, and he'd put me straight in for an MRI if that happened - but was happy to release me as a-ok
