"The patellar tendon is biconvex and, similarly to the Achilles tendon, does not have a tendon sheath but only a paratenon composed of loose areolar tissue. It measures approximately 5 cm in length (i.e. height of the patella) and 20-30 mm in width, being wider proximally and narrower distally, and is 4-6 mm thick 2-4."

"Identified between the caudal tip of the patella and the tibial tuberosity, the tendon appears as an ovoid structure just deep to the subcutis; characteristic echotexture of striated alternating hyperechoic and hypoechoic bands representing fascicles and connective tissue, respectively. The body of the tendon maintains constant dimensions throughout the majority of its course, expanding to insert on the tibial tuberosity."
