There can be several causes of this type of pain. The first possible cause can be biceps femoris tendonitis. This is a medical term for the inflammation of the hamstring tendon which is a muscle that attaches on the back of the upper leg. This muscle hooks into the back of the knee. Pain mainly occurs with bending of the knee and can be caused by kicking sports, running downhill and sprinting.

Baker’s Cyst

Next is a Baker’s cyst. This medical condition is officially known as a popliteal cyst. With this problem, there is localized swelling at the back of the knee which causes increased pressure that results in pain. The classic sign of a baker’s cyst is a golf ball sized knot on the back of the knee.

Popliteus Tendonitis

Another possible condition can be popliteus tendonitis. The popliteus muscle is a small muscle in the back of the knee that works to turn the lower leg bone in. Symptoms typically include tenderness with pushing in at back of knee. Pain may also occur with the knee bent and foot turned outward.

Gastrocnemius Pain

Another possible issue is gastrocnemius pain, which is inflammation of the Achilles tendon of the large calf muscle. This tendon starts at the back of the knee and continues down into the heel. This problem is usually an overuse injury with pain at the inside of the back of the knee.

Deep Vein Thrombosis DVT

Two other issues to be aware of are Deep Vein Thrombosis (DVT) and posterior cruciate ligament injuries (PCL). DVT is commonly referred to as a blood clot, which usually occurs following surgery or long periods of immobilization. Typical symptoms of DVT include swelling in the affected leg as well as pain that feels like cramping or soreness. This can be a serious life threatening occurrence that should not be easily dismissed.

Posterior Cruciate Ligament Injuries

Posterior cruciate ligament injuries (PCL) can also cause pain at the back of the knee. The PCL is a ligament that keeps the knee from bending back the wrong way and is injured when the knee is forced the wrong way. Symptoms can also include minimal swelling and a feeling of instability.
