A popliteus strain is when the muscle fibres tear due to too much force being applied to the muscle. There are three categories a popliteus strain can be decribed as. These are: Grade one – damage to less than 5% of the muscle fibres. Grade two – extensive damage with more than 5% of the muscle fibres involved.

What does a popliteus strain feel like?

What does the popliteus muscle do?

Despite its small size, the popliteus is a major stabilizer of the knee. The popliteus is involved in both the closed chain phase and open-chain phase of the gait cycle. During the closed chain phase, which is when the foot is in contact with the ground, the muscle externally rotates the femur on the tibia.

Why does the back of my knee hurt when I straighten my leg?

Can tight hamstrings cause pain behind the knee?

The most common muscles to become tight and cause anterior knee pain are your hamstring muscles (at the back of your thigh) and your quadriceps muscles (at the front of your thigh) – see diagram. If these muscles become tight they cause pressure over your patella (kneecap) causing it to rub on the joint beneath it.
