Pain Behind The Knee (Posterior)

Posterior knee pain is pain at the back of the knee. Below we outline the most common causes of pain at the back of the knee, less common causes, as well as important conditions and injuries that should not be missed. Biceps femoris tendonitis (hamstring tendonitis) is probably the most common over use injury at the back of the knee although referred pain and various causes of swelling are also likely causes of pain at the back of the knee.

 

Gastrocnemius Tendinopathy

Gastrocnemius tendinopathy or tendinitis is inflammation or degeneration of the tendon of the calf muscle causing pain at the back of the knee. This is an overuse injury which is more common in runners and sprinters. Treatment involves reducing the pain and inflammation followed by a full rehabilitation and exercise program to restore the muscle and tendon to full function.

Biceps Femoris Tendinopathy

Biceps femoris tendinopathy, sometimes called biceps femoris tendonitis is inflammation or more likely degeneration of the tendon at the point where it inserts at the outside back of the knee. Here we explain the symptoms, causes, and treatment as well as rehabilitation and exercises.

Baker's Cyst

A Baker's Cyst or Popliteal cyst is a prominent swelling at the back of the knee. It is usually caused by an underlying injury or condition in the knee joint but the athlete is often unaware of the exact cause. Here we explain the symptoms, causes and treatment options.

Tennis Leg

Tennis leg is a general term used to describe pain in the leg caused by a tear of the inner head of the big calf muscle, the plantaris muscle or sometimes both. Here we explain the treatment including immediate first aid as well as rehabilitation exercises essential for optimum recovery.

Posterolateral Corner Injury

Posterolateral corner injuries cause pain at the back and outside of the knee. They are not particularly common injuries, although around half of cases occur due to sporting injuries, with road traffic accidents being another common cause.

Popliteus Injury

The Popliteus is a small muscle located at the back of the knee joint. An injury or strain to the muscle or tendon can cause pain at the back of the knee. This knee injury can occur gradually through overuse or can result from a sudden twisting, fall or collision.
