Why do knee joints pop

Causes

  • Gas bubbles. Over time, gas can build up in the areas surrounding the joint, forming tiny bubbles in the synovial fluid.
  • Ligaments. The ligaments and tendons around the knee joint may stretch slightly as they pass over a small bony lump.

  • Ligament or tendon snapping.
  • Bone grinding.
