What Are Possible Causes And Diagnosis Of Back Of Knee Pain?

Injuries or other health conditions, such as arthritis or cysts, may cause pain in the back of the knee. Pain in any body part should never be ignored, either it is severe or mild. Because pain itself can be an indication of something serious. When a person feels pain in the back of the knee, a blood clot may be the cause, which is a very serious condition. You have to restrict your movements in case of severe pain or injury, and you have to follow precautions to stop worsening of pain. You should consult pain management doctors for better diagnosis and treatment.

Symptoms of Back Of Knee Pain

Below are some examples of problems you may experience, such as swelling or pain.

  • It is likely that you will also experience injuries to other parts of your knee if you suffer a posterior cruciate ligament (PCL) injury.
  • The discomfort you feel will be minimal if your PCL has only been injured.
  • Kneeling may cause you to experience pain behind your knee.
  • Walking or running downhill, or descending stairs, may be uncomfortable if your symptoms do not improve. 
  • Your knee will probably experience swelling and sometimes pain due to a popliteal cyst.
  • As time passes, the swelling may improve or deteriorate.
  • You should be able to feel better after moving around for a while. Knee swelling may also be present.

Causes of Back of Knee Pain

There are many causes of back of knee pain, some of them are as given below.

  • Osteoarthritis 

Legs are difficult to bend or stretch. It is possible that your knee may become stiff and sore after moving, as well as swell. Your cartilage, which cushions your bones, may have worn out. In view of the fact that this type of arthritis takes time to develop, it is more common in people over the age of 65. Younger people may suffer from this condition if they have used their knee a lot following an injury, such as a ligament tear.

  • Torn Meniscus 

When you twist or pivot with your full weight on your knee, the rubbery cartilage that cushions the joints between your shin and thigh can be torn. Each knee has an ACL on both sides. Tears may be more likely to occur in individuals who suffer from arthritis or are aging. Defining and pinpointing pain can be challenging. You may experience swelling, stiffness, and limited mobility as a result of knee injury. 

  • Overextended Knee

Overextended knees are caused by an unnatural bend in the knee joint. Pain behind the knee is caused by this damage to the knee structures.Sports injuries that cause knee hyperextension are often painful and instabile. As you stand, walk, or climb stairs, symptoms usually worsen.

  • Infection 

A secondary infection or direct injury to the joint can result in septic arthritis. As well as experiencing pain, you will be sick, cranky, and suffering from a fever. A needle may be used by your doctor to collect fluid from your knee to determine what bacteria is causing it so they can determine how to treat it. Even though it does not occur as frequently as viruses and parasites, your joints can be affected by them as well.

Identifying the Source Of Knee Pain

The diagnosis is made on the basis of results from multiple tests and imaging studies.

  • An examination of the patient by the doctor is typically preceded by a review of the patient’s medical history.
  • Athletes and athletes frequently suffer from soft tissue injuries including inflammation and rupture (tear) (cartilage, tendon, meniscus). Arthritis or cysts are common causes of posterior knee pain in the older population.
  • An X-ray, an MRI, or an ultrasonography may be used to detect the abruptions underlying the spine.

Contacting a Medical Professional When Necessary

The following symptoms may occur:

  • Weight cannot be supported by your knees.
  • The pain persists even when you do not lift weights.
  • A buckling, clicking, or locking sensation occurs in your knee.
  • Your knee has a deformity or a misshapen appearance.
  • It is not possible to bend or straighten your knee.
  • A swollen, red, or warm area is present around the knee.
  • Symptoms include calf swelling, numbness, tingling, or bluish coloration below the sore knee.
  • If you can not get relief even after 3 days.


The RICE treatment is often recommended by doctors when an injury occurs in order to decrease pain and swelling. An acronym for RICE is:

  • Resting (the leg)
  • Icing (the knee)
  • Compressing (the area with an elastic bandage)
  • Elevating (the injured leg)
  • For information about what treatment is appropriate for each individual, a doctor or physical therapist should be consulted.
  • As the knee recovers, nonsteroidal anti-inflammatory drugs (NSAIDs) can be used to reduce swelling and pain. There are some NSAIDs which can be purchased online,such as ibuprofen.
  • Stretching the muscles around the knees, particularly the quads, calves, and hamstrings – is always a good idea. While this may not provide protection against some traumatic causes of knee pain, it may help the muscles respond more effectively to physical activity.
  • A physician may recommend steroid injections to reduce symptoms in some cases.
  • Physical therapy or surgery may be recommended depending on the severity of the condition.
  • More serious injuries may require the use of a CT scan or an MRI to obtain a comprehensive picture of the area. 


An injury to the back of the knee may be the symptom of a more serious condition. Patients who experience severe symptoms or symptoms that persist for more than a few days should consult a physician. If you follow the treatment plan prescribed by your physician like Dr Zulqarnain, your injury may have the best chance of healing properly and preventing complications.
