Pain Behind The Back Of The Knee: Treatments And Causes

Most people will experience pain behind the back of their knee at some point in their lives. The causes can be many and varied, from sports injuries to arthritis, and the treatments can be just as diverse.


In this blog post, we will explore the various causes and treatments for this type of pain, so that you can better understand what might be causing your discomfort and how to best address it.

Knee joint


The knee joint is a hinge joint that allows for flexion and extension of the leg. The knee joint is stabilized by ligaments, including the anterior and posterior cruciate ligaments and the medial and lateral collateral ligaments. These ligaments control the range of motion of the knee and prevent excessive movement.


What is a meniscus tear?


A meniscus tear is a type of knee injury that occurs when one or more of the menisci, which are cartilage discs that cushion the knee joint, are torn. The menisci help to distribute weight across the joint and protect it from wear and tear. Meniscus tears can be caused by a number of activities, including sports, accidents, or simply bending the knee too far. They can cause pain and swelling in the knee and make it difficult to move.


What's a baker’s cyst?


A baker's cyst is a type of swelling that can occur behind the knee. It is caused by a build-up of fluid in the joint space between the femur and tibia. The most common cause of a baker's cyst is a tear in the meniscus, which allows fluid to leak into the joint. Baker's cysts can cause pain and swelling in the knee and make it difficult to move.


What anatomy is at the back of the knee?


The anatomy at the back of the knee includes the hamstrings, the calf muscles, and the Achilles tendon. The hamstrings are a group of muscles that run along the back of the thigh. The calf muscles are a group of muscles that run along the back of the lower leg. The Achilles tendon is a tendon that runs from the calf muscles to the heel. These muscles and tendons work together to flex and extend the leg.


Physical therapy

If you are experiencing pain behind the back of your knee, your doctor may recommend physical therapy as a treatment option. Physical therapy can to improve the range of motion and strength of the knee joint and reduce pain and swelling. Therapists will typically prescribe a mix of exercises and stretches to help you regain mobility and strength.
