Cutaneous branch of the obturator nerve Cutaneous branch of the obturator nerve Occasionally the communicating branch to the anterior cutaneous and saphenous branches of the femoral is continued down, as a cutaneous branch, to the thigh and leg, as the cutaneous branch of the obturator nerve. When this is so, it emerges from beneath the lower border of the Adductor longus, descends along the posterior margin of the sartorius to the medial side of the knee, where it pierces the deep fascia, communicates with the saphenous nerve, and is distributed to the skin of the tibial side of the leg as low down as its middle.
Articular capsule of the knee joint the suprapatellar bursa is seemingly redundant. It is however also referred to as the "suprapatellar synovial recess" as it gradually unfolds as the knee is flexed; to open up completely when the knee is flexed 130 degrees. The suprapatellar bursa is prevented from being pinched during extension by the articularis genus muscle. On the tibia, the anterior reflection and attachment of the synovial membrane is located near the cartilage. Anteriorly, the infrapatellar fat pad is inserted below the patella and between the two membranes. It extends from the lower margin of the patella above, to the infrapatellar synovial fold below.
