In scuba diving, microbubbles are what many blame decompression sickness on. I wonder if it may be possible to attach some sort of ultrasonic beeper to periodically burst them somewhere safe?
In scuba diving the bubbles are made of Nitrogen, that can't dissappear. It must get slowly disolved in the blood and get out of the body in breath.
Also, though perhaps not rate limiting, ultrasound might be able to mess with the N2 bubble boundary diffusion rate.
Caveats: Very not my field; no clinical practice; mostly animal studies; mostly musculature and not joint; and under-validated AI.
Meta: But I so very much enjoy surfing literature with AI. Even with AI's rich collection of interesting failure modes. They serve as fun added encouragement to keep you on your toes, and keep clear on the gradients of your confidence.
