Meniscus, meniscal.
Cleaning out your meniscus is not something you can just “do”. Neither is repair. It’s very much a last resort, there are half a dozen other things to look at first.
Cleat position (as mentioned already) don’t just tweak randomly, check your previous shoes, or get someone to look at it. Could also be a change in stack height or the angle of the sole (specialised build in a 2 degree angle, a few other manufactures do similar, i prefer to shim my cleats where needed)
Also there could be a difference in arch support. (Forgot the insoles in my shoes on a ride a couple of weeks ago, didn’t realise until i got to the start. That hurt.)
