Some opinions and options:
First, MRIs are notorious for being difficult to interpret once you have hardware like ADRs in the image. I'd look for someone who can order and interpret flat film x-rays: front and side view as well as flexion and extension. That'll give you an idea of whether ADRs were placed correctly, if they subsided or shifted after placement and if they're functioning correctly.

Second, I'd suggest looking for someone who can handle whole body motion physical therapy. Get them to assess your general motion and position: sitting, standing, and walking at the least. See if you have improper loading from improper motion. This can even be residual improper motion from ingrained habits formed prior to your ADRs.

Those two shouldn't be too expensive, though I don't know anything about your medical system in your region. You might end up paying a premium to get someone who'll do what you need, not what the insurance or medical standards say you need.

You might have adjacent spinal levels checked for disk height on the x-rays just in case you have another level beginning to desiccate. Figure skating is pretty well known to be punishing to the body so that could be happening. For that matter, your SI joints might have also been damaged. They radiate in a pain pattern very near to L4/5 and L5/S1 so they can be mistaken for spine problems.
