👉 Arthroepathy, also known as "arthroscopic empyema," is a condition where the fluid that normally fills the joint space in the knee or hip joint becomes inflamed and obstructs the flow of blood. This condition can be caused by various conditions such as arthritis, meniscus tear, or an infection. Inflammation of the joint space can cause pain and restrict movement, which is why it's important to seek medical attention if you suspect you have arthroepathy
