There are three muscles which cross the medial (inside) joint line of the knee. These are one of the hamstring muscles (semitendinosus) and two of the long hip adductor muscles (gracilis and sartorius). They insert inside of the shin bone and form what is known as the pes anserinus, due to its resemblance to a goose’s foot. These tendons can become inflamed with repetitive trauma such as running in poor trainers or on sloped surfaces such as beaches. Deep to the pes anserinus is often a bursa. This can sometimes become enlarged with fluid and may be secondary to chronic irritation by the tendons which overly it or occasionally infection.
