Possibly!
But I do really wonder at the medical advice certain Belgian riders get. I'm not saying he should have tried rushing back too quickly, 'rebuilt' up his damaged parts, and racing earlier. But I do think he full on rested (as in no stationary bike work, no other aerobic work, not a whole lot of gym work) for longer than likely needed. I seem to recall Wout also taking a lot of time to recover.
And to anyone getting hot under the collar about these ideas ... I do have experience in healthcare and rehabilitation. This is not just random armchair quarterback musings.
While not directly related it is somewhat analogous to the science of concussion recovery. It used to be rest, rest, rest, and then rest some more. Don't overstimulate the brain, etc. It now is a much more structured and graded, but early, return to exercise and other stressors. And it appears to be much more successful.
