What is a Hamstring Tear?

How Does a Hamstring Tear Happen?

In the late phase of running, the muscle is stretched while contracting forcefully; a load that exceeds its capacity tears the fibres. Poor warm-up, fatigue, muscle imbalance, low flexibility and a previous hamstring injury increase the risk. Football, athletics and dance are the most common settings.

Symptoms

• Sudden sharp pain at the back of the thigh while running, sometimes with a popping sensation
• Bruising at the back of the thigh within a few days
• Pain when bending the knee or leaning forward, limping
• In severe tears, a dip or gap near the sitting bone

Frequently Asked Questions

How long does a hamstring tear take to heal?

Mild strains heal in a few weeks and partial tears usually within a few months with progressive rehabilitation. If ultrasound or MRI shows a complete detachment from the sitting bone, early surgical repair may be needed. Return to sport is planned after strength and flexibility tests are passed.
