Meniscus tear likely: Posterior horn especially of the medial meniscus gets loaded when the knee is bent. Torn peice can spit out or get caught between tibia and femur causing that painful catch you describe. Not an emergency unless the knee gets locked or stuck in one position and you csnt work it loose. Arthroscopic surgery can usuall treat
