Hello. Thank you for your message.
Behind knee pain (also known as posterior knee pain) is one of the most common forms of pain.
Some causes of posterior knee pain:
Baker's cyst. A Baker's cyst is one of the most common causes of pain behind the knee. Throughout the body, there are fluid-filled sacs called bursa which help lubricate and cushion our body parts as we move. When the bursae behind the knee become inflamed, this is known as a Baker's cyst.
Arthritis - The natural wear and tear of our knee joint (osteoarthritis) or inflammation in the knee joint (rheumatoid arthritis) may cause pain behind knees. The pain may be more severe in the morning when the joint is the stiffest.
Meniscus Tear - The menisci of the knee are the pieces of cartilage that cushion the knee joint. When the posterior portion of the meniscus is torn, it may cause pain behind the knee (or all over the knee with more acute pain toward the rear).
Other causes - Direct trauma to the knee may also cause behind knee pain. Your doctor will diagnose whether it is a knee sprain (overstretched ligaments) or a ligament tear in this case.
