They are comprised of compact connective tissue consisting of collagen fibers. The peritenon is a layer of loose connective tissue that wraps around the tendon. Large tendons have lymphatics and vessels that course between septa, and small tendons have almost no vascularity. Tendons can attach to tuberosities, processes, or ridges. Synovial sheaths are double walled cylinder shaped structures the surround some tendons. Small amounts of synovial fluid can be found within these sheaths to act as a lubricant for the moving tendons. Large tendons do not contain synovial fluid. Tendons appear hyperechoic to surrounding anatomy on ultrasound. Sonography can be performed on tendons of the shoulder, elbow, hand and wrist, knee, foot and
