- An X-ray, which is an invisible magnetic energy beams to create images of internal bone and tissue
- Magnetic resonance imaging (MRI), which is an electric transmission of energy, magnet, and computer that is used to detect damage or disease in the body
- Computed tomography scan (CT or CAT scan), which is an electric transmission of energy and computer that creates extremely detailed images of bones, muscles, and organs
- Arthroscopy, which is a medical procedure using a small tube inserted through a small incision into the joint. Images from inside the joint are projected onto a screen and used to determine the pain source
- A radionuclide bone scan, which is a medical procedure where a tiny amount of radioactive material is injected into the bloodstream. A scanner is used to see the blood flow and determine the source of the pain
Treatments for pain in the back of your knee
Healthcare providers usually treat pain in the back of your knee based on the underlying cause of the pain or injury.
Rest, ice, compression, and elevation
If you have sudden, intense pain in the back of your knee, the doctor may recommend that you rest and apply ice to your knee. In some cases, your doctor may also ask you to elevate (prop up) your leg while you’re sitting down to help improve the blood flow in your leg.
Exercise and physical therapy
Some exercises can help build muscle and relieve pain in the back of your knee. It is important to work with your doctor or physical therapist to determine which exercises are right for you so you can avoid potential injury.
Your doctor may ask you to make some lifestyle changes to help relieve pain in the back of your knee. This could include things like maintaining a healthy weight and avoiding activities like running or placing too much pressure on the knees.
Genicular nerve blocks
This medical treatment blocks pain signals between the knee and the brain, which offers relief from pain in the back of your knee. This is a nonsurgical option done by injecting an anesthetic (a drug which results in the loss of sensation) into the affected area.
Peripheral nerve stimulation
This is a medical procedure where a surgeon puts electrodes (electrical conductor) and a battery pack near the nerves inside the knee. This creates an electrical current that tricks the body into turning off pain signals, which relieves pain in and around the knee.
This could include over the counter medications like acetaminophen (anti-inflammatory drugs) or stronger medications like opioids (strong pain-relieving drugs) and steroids (synthetic drugs that decrease inflammation) that are prescribed by a doctor.
Your doctor may recommend surgery if the pain in the back of your knee is due to structural damage. The type of surgery depends on each person’s unique situation and circumstances.
Complications and side effects of pain in the back of your knee
Some treatments may cause possible complications and side effects. It is recommended to speak to your doctor about the best options available for you. For instance, if you receive peripheral nerve stimulation or genicular nerve blocks, you may experience:
- Nerve damage
- Damage to the surrounding area
- Worsening pain
Other medications may have different side effects. Consult your healthcare provider about possible complications of any medications you might take for relieving pain in the back of your knee.
