Meniscus Injury
The meniscus is the piece of ligament that pads the knee joint as we walk. Depending upon where on the meniscus a physical issue has happened, a patient may experience pain in the back of the knee. [2]
Weakness of the muscles
Muscles around the knee or joint inflammation may likewise cause pain in the back of the knee. There may likewise be different reasons for inside knee pain, however weakness of the muscles surrounding the knee joints is one of the most common reasons. [3]
