Saphenous Nerve Entrapment and Knee pain
The adductor canal is an opening in which the cutaneous nerve travels through to supply sensation to the skin over the inner portion of the knee and down the leg. This soft tissue tunnel is a common point that becomes compressed (pinched nerve) or the mobility of the nerve is limited.
Once the nerve exits the adductor hiatus it supplies sensation to the knee via the infra-patallar branches. The saphenous nerve and it’s branches also innervates the heavy ligament on the inner knee known as the Medial Collateral Ligament. This is the ligament that prevents your knee from buckling inwards and gives the knee stability. There sudden or repetitive loading of the inner knee can create saphenous neuralgia.
Activities such as running, walking, standing from sitting and squatting can created pain in the vessels and nerves when the knee traveling towards midline (valgus collapse).
