Application of extracorporeal shock wave therapy in knee arthritis

Knee osteoarthritis (KOA) is a chronic bone and joint disease mainly characterized by degenerative degeneration of knee cartilage and secondary bone hyperplasia. Therefore, itis also known as proliferative arthritis of knee joint, degenerative arthritis and osteoarthropathy, mainly manifested as pain, swelling, stiffness and affected joint motion.

01 epidemiology

Osteoarthritis is the most common form of arthritis, and knee osteoarthritis is the most common form of osteoarthritis.
The total incidence of osteoarthritis in the population is about 20%, more women than men, the age of onset is mostly concentrated in 40~65 years old, the peak age is 50 years old, and the prevalence of people over 65 years old is 68%.

The total prevalence rate of adult KOA is about 15%, which is common in middle-aged and elderly people over 50 years old. With the acceleration of population aging process, the prevalence rate is increasing. Prevalence is as high as 50% in people over 60 years of age; The figure is as high as 80% for those over 75. The peak incidence of male and female patients was 24.7% and 54.6%, respectively.
The knee joint, which is composed of the inner femur, lateral condyle, inner tibia, lateral condyle and patella, is a large and complex joint with more chances of injury.

02 Classification of arthritis

Knee arthritis is a common disease of the knee joint, and common arthritis can be divided into three types.

Osteoarthritis: Common arthritis, generally considered to be a chronic progressive degenerative disease. Characterized by chronic wear of cartilage. Often in the middle and old age, in the early stages of the disease, no obvious symptoms, or mild symptoms. In the early stage, it is often manifested as stiffness and discomfort in the joints, which improves after activity. Acute inflammation may occur in the event of intense activity, which is relieved after rest and symptomatic treatment.

2. Post-traumatic arthritis: It is arthritis that gradually appears after trauma to the knee joint. The clinical presentation is similar to osteoarthritis, but there is a clear history of trauma, such as ligament damage or meniscus damage.

3. Rheumatoid arthritis: It is an inflammatory type of arthritis. In the early stage, synovial inflammation of joints is the main one, and then the joint cartilage is eroded, resulting in serious loss of joint function. In the late clinical symptoms of osteoarthritis, serious deformities remain. Rheumatoid arthritis can occur at any age, mostly in young people, and usually affects both knees.

03 Therapy

Knee arthritis in the knee movement of the pain will be aggravated, and early paroxysmal change to persistent pain, especially at night. This also causes the knee joint movement is limited, limp symptoms, if not continued treatment, the joint will appear deformed phenomenon.

1. Conservative treatment

Including medicine, massage, heat therapy and so on. Most of the drugs are painkillers, which can relieve pain, but these drugs have great side effects on the gastrointestinal tract. Massage and other methods, but also to ease the pain.

2. Surgical treatment

Arthritis is recurrent and the joint is malformed, so surgery is needed. But if that's not the case, surgery is not an option. Because surgical treatment is traumatic and complicated, it is not a good choice for patients.

3. Shock wave therapy

Shock wave isa kind of mechanical wave, which has some properties of acoustics, optics and mechanics. It is a kind of sound wave with mechanical characteristics that causes the rapid compression of the medium and generates energy through vibration, high-speed movement, etc., which can cause changes in the physical properties of the medium, such as pressure and density.

04 What is shock wave therapy?

Shock wave is a kind of mechanical wave with sound, light and mechanical characteristics, which can conduct freely in human body. When the shock wave conducts in human tissue, the tiny bubbles will produce microjets, accompanied by the rapid expansion of bubbles, resulting in cavitation effect.


In addition, due to the stimulation of the shock wave on the nerve endings, the sensitivity of the nerve can be reduced, causing the change of free radicals around the cells to release pain-inhibiting substances, raising the pain threshold, thereby reducing the pain. Because the density of human soft tissue is similar to that of water, shock waves do not cause damage to the human body.

At present, extracorporeal shock wave therapy as a non-invasive treatment can play a role in reducing pain and relaxing muscles, has been used in many fields.

What are the advantages of shock wave therapy?

·Dual gun shock wave, dual channel independent use!!!
·Comes with 12 therapeutic guides!!
·With multiple treatment prescriptions, you can choose the corresponding treatment prescription according to the body part.
·It has the function of case storage.
·It has the function of pain VAS evaluation.
·It has the function of connecting printer.
·Output mode: single mode, manual pulse, automatic pulse, automatic intermittent.
