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
