So, I injured my left index finger to the point of tendon interruption. It was approx 2018. I was fortunate enough to have surgery that repaired it to near 100% extension. So, I clearly have no synovial fluid at that joint. The tendons were in it, and so by necessity it was also violated. I just popped that knuckles, and it sounds exactly like the others. Anyone have any ideas?
