PES ANSERINE PAIN (Knee Tendon)
Definition:
Pes: foot Anserine: of a goose
Pes anserine pain/bursitis is an inflammation of the area located between the shinbone (tibia) and three tendons that inserts at the inside of the knee. Pain and tenderness on the inside of the knee, about 2-3cm below the knee joint, are common symptoms.
The 3 tendons that inserts below the knee comes from two of the muscles on the inside of the leg (adductors) as well as one of the hamstring muscles.
Under these tendons is a bursa (fluid filled sac) which is important in reducing friction between the tendons and the bone. This can also get inflamed.
Causes:
*sport (eg. running)which involve repetitive use of the named muscles
*abnormal hip, knee or ankle biomechanics
*muscle imbalances eg. weakness or tightness of hip and/or knee muscles
*poor foot arch control
*worn shoes
*sudden increase in activity
Symptoms:
*gradual onset of pain over area – especially when bending and straightening the knee
*inner knee pain when going up or down stairs
*swelling over area
*tenderness over area
Treatment options:
*Diagnosis of reason for symptoms (Physiotherapy assessment can help with this)
*Rest, ice and medication to reduce pain and swelling
*Stretching of the hamstrings and adductor muscles
*Strengthen hip and knee muscles
