In my left knee there’s this popping that happens whenever

Patient: In my left knee there’s this popping that happens whenever I bend/flex my knee, and it feels as if a ligament/tendon is getting caught on something inside the left part of my knee and keeps popping and feels like it snaps after being dislodged from wherever it’s getting caught. Standing and walking is uncomfortable and it is becoming concerning and painful

Symptoms: Pain, snapping, clicking
