Pes anserinus means

• The term, pes anserinus means "goose´s foot" in Latin - owing to the webbed-foot pattern the three tendons make when they meet.

Pes Anserine Bursitis/tendonitis

Pes anserine bursitis/ tendonitis

• is a painful, inflammatory condition affecting the tendons and/or lubricating sac (bursae) between your shinbone and the hamstring tendons at the inside of your knee; typically caused by stress to the area.

Pes anserine bursitis/ tendonitis

• Specifically, the pes anserinus is the area where the tendons of 3 muscles (sartorius, gracilis, and semitendinosus) come together.

• The three tendons merge together in the skin of the bone on the inside surface of the shinbone.

Biomechanics

• These three muscles are the dominant knee flexors; they influence the rotation of the tibia and protect the knee against rotary stress.

Symptoms• Pain located 2 to 3 inches below the

kneecap

• swelling in front of the kneecap (prepatellar) or underneath the kneecap (infrapatellar)

• Pain increasing with exercise or climbing stairs

• Pain and often warmth and tenderness when touched

• Pain when bending or straightening the knee.

• Pain that radiates to the back and inside of the thigh

Symptoms

• Visible swelling and/or redness of the tendon sheaths (tendonitis)

Cause

• It is generally agreed that hamstring tightness is the most common cause

Pes Anserine Causes

• Inflammation of the bursae or tendons serving these muscles usually develops due to overuse, trauma, or degradation typically from:– Tight hamstrings– Obesity– Poor sport technique, including improper warm-up,

excessive hill work, increased mileage– Biomechanical issues, such as foot rolling, out-turned

knees– Osteoarthritis– A medial meniscus tear

Cause

• common in athletes (particularly runners), overweight individuals, and often, people with osteoarthritis of the knee.

Causes

• Overuse, or excessive stress of the knee joint

• Runners may suffer from this if they significantly increase their mileage, change shoes, or have worn out shoes, or change the surface they are running on.

Prevention

• gait and your posture

• but most importantly, warm up your hamstring
