Laser Therapy for Knee Pain: Does It Work?

Nowadays, there is an alternative therapy for some types of pain, including knee pain. Laser therapy for pain management is a revolutionary and very effective form of treatment. Also known as low-level laser therapy, class III laser therapy, or cold laser therapy, this treatment uses beams of light energy to reduce inflammation and pain.




Cold laser therapy exposes tissue in the treatment area to low levels of near-infrared and red light. The levels of light are significantly low compared to other laser treatments that produce heat. These include lasers used for ablation or cutting.


How It Works


Physicians use different wavelengths of light energy to treat specific conditions. The light penetrates the skin into the tissues and triggers a physiological reaction. This reaction may improve circulation, reduce inflammation, and promote healing. This form of therapy can be an effective solution for a wide range of problems, including knee pain caused by osteoarthritis or injury.


What to Expect


During the procedure, your physician will administer cold laser therapy using a small handheld device. It is a non-invasive form of treatment that a doctor, physical therapist, or clinician can perform. However, you should avoid looking directly into the laser as it can harm your eyes. This is the reason most doctors give their patients protective eyewear during the procedure.


Your doctor/physical therapist/clinician will hold the handheld cold laser device close to the skin on your knee for a few minutes. The length of time they do so will depend on the size of the treatment area and the dose. The light energy will pass through your skin into the inner tissues.


The tissues will absorb it, helping reduce inflammation in addition to promoting regeneration of the injured or damaged tissue. You may need more than one treatment to experience relief from pain. This will depend on the level of damage to your knee.


Does the Procedure Hurt?


This form of treatment is generally pain-free. You might experience a slight tingling sensation. However, you will not feel cold or heat. Furthermore, there is no drawn-out recovery time. Thus, you can go home immediately following the treatment.


Does It Relieve Knee Pain?


Laser therapy for knee pain is a relatively new form of treatment. Thus, researchers are still performing studies to determine whether it has any long-term risks. According to proponents of cold laser therapy, this type of treatment provides both temporary and long-term pain relief and healing.


People with knee injuries caused by diseases or trauma may benefit from laser therapy. A combination of physical therapy and low-level laser therapy may eliminate bone to bone knee pain. This form of treatment aims to reduce or eliminate the irritation and inflammation of arthritis.


Physical therapy, on the other hand, strengthens the surrounding ligaments and muscles, reducing the pressure on the knee joint. When applied properly, cold laser therapy can help an injured knee joint heal faster. This is because it stimulates the body’s healing mechanism and boosts blood circulation.
