👉 A rectisura is a type of muscle that bulges or protrudes from the surface of a skin fold, especially on the upper part of the thigh. These muscles are often found in the region between the knee and ankle joints, and they help to stabilize the joint and provide support for the leg muscles. Rectisurs are typically associated with certain types of arthritis, such as rheumatoid arthritis or osteoarthritis, where their protrusion can lead to pain and discomfort.
