Knee Pain

The knee is the largest joint in our body and has to withstand various stresses as we go about our day to day activities. Many of us have experienced a knee problem at some point in our lives, whether from playing sports or working around the house, but sometimes discomfort can develop for no apparent reason at all.

Knee pain can come from inside the joint where important structures such as the meniscus, ACL and PCL are, or from the surrounding muscles, tendons, ligaments or bursa. It may start suddenly from an acute injury (such as falling, twisting the knee, bending the wrong way, or a direct blow while playing sports). Acute injuries can lead to a build up of Internal Scar Tissue which can become more problematic than the original injury itself. Knee pain can also develop over time from overuse or daily wear and tear, often causing symptoms of Osteoarthritis.

It’s important to know that some people may be more likely to develop knee problems than others. Certain jobs, sports or recreational activities, genetic predisposition and other conditions (like gout, rheumatoid arthritis or osteoporosis) can also contribute to one developing knee issues.

Common Symptoms

  • Pain or soreness in or around the knee
  • Pain may increase with squatting, twisting, or going up/down stairs
  • Swelling and/or bruising
  • Limited range of motion
  • Stiffness, especially after not moving for a period of time
  • Popping or grinding
  • Knee may lock, catch or give way

Conditions That Cause Knee Pain

  • Internal Scar Tissue

    Internal Scar Tissue is a thick, tough, fibrous material that the body creates to quickly repair a damaged tissue such as muscles and tendons. It can build up in any area of the body where there has been internal and/or external damage. Internal Scar tissue is a very common cause of recurring or chronic pain after sport or work injuries, after surgery and it also often intermixes with Osteoarthritis.

  • Knee Osteoarthritis

    Inflammation of the knee joint caused by progressive degeneration from wear and tear, resulting in the breakdown of the knee cartilage (natural joint lubricant) and joint surfaces. Common symptoms include pain, stiffness, swelling, reduced mobility and grinding.

  • Knee Sprain

    Sudden overstretching of one or more ligaments in the knee. Commonly sprained knee ligaments include: anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial cruciate ligament (MCL) or lateral cruciate ligament (LCL). These injuries are usually caused by direct blows to the knee, hyperextension, or sudden twisting. Sometimes a pop may be felt at the time of injury, with swelling developing within 1-2 hours.

  • Meniscus Inflammation

    Inflammation of the cartilage that cushions and lubricates the knee joint. This condition can be caused by prolonged stress on the knee like crouching a long time for gardening or other activities. An inflamed meniscus causes pain which may radiate down the leg, swelling and tenderness of the area, even when sitting down.

    In most cases, it heals by itself, but when it persists for weeks, it’s worthwhile treating to avoid further and secondary complications. Read Maxine’s story to find out how Cold Laser Therapy helped her.

  • Meniscus Tears

    Damage to the cartilage that cushions and lubricates the knee joint. This is one of the more common knee injuries, usually caused by a forceful bend or twist of the knee while having your full weight on it. A torn meniscus causes pain, stiffness and swelling, and potentially may cause your knee to feel unstable.

  • Patellar Tendonitis (Jumper’s Knee)

    Small tears in the tendon that connects your kneecap (patella) to your shin bone, causing inflammation and pain. Jumping activities can cause this condition, as well as other repetitive stress movements of the knee.

  • Iliotibial Band (ITB) Syndrome

    Irritation and inflammation of the iliotibial band (ITB), a thick fibrous band that run along the outer thigh to the outside of the knee. Pain is felt on the outside of the knee (and sometimes thigh) during physical activities such as running, biking, hiking and walking up or down stairs.

  • Knee Bursitis

    Inflammation of one of the bursa, fluid-filled sacs that facilitate normal motion and reduce friction between structures around the knee. Various causes of bursitis include direct trauma to the knee, inflammatory arthritis or other inflammatory conditions, internal knee damage or infection.

  • Osgood-Schlatter’s Disease

    This is the most common knee problem in children and adolescents going through a growth spurt. It is a painful lump on the shin below the kneecap, usually occurring in active children who participate in various sports involving running, jumping and quick changes of direction.

Cold Laser Therapy for Knee Pain

Cold Laser Therapy Knee Pain Treatment: Step 1

Decreases Inflammation: Speeds up the body’s natural inflammation phase and induces the repair phase of healing.

Removes Internal Scar Tissue: Inhibits and removes Internal Scar Tissue that naturally forms from injury or repetitive strain, causing discomfort and a delay in healing.

Cold Laser Therapy Knee Pain Treatment: Step 2

Regenerates Muscle Tissue: Transfers light energy to the affected cells of muscle, regenerating and strengthening damaged muscle tissue to prevent future injury.

Activates Cartilage Production: Promotes the natural cartilage growth process by increasing the production of cellular energy (ATP).

Cold Laser Therapy Knee Pain Treatment: Step 3

Accelerates Bone Repair: Simulates the bone cells to replicate and produce new healthy bone tissue.

Nerve Regeneration: Helps damaged nerves to recover by growing the neural network and repairing vital insulation around the nerve.

Stimulates Blood Flow: Increases the delivery of oxygen and nutrients required for healing of the affected cells.
