Sequelae of ozone injection in knee joint

Nowadays, the elderly all have rheumatic diseases, and knee pain is very common among the elderly. Knee pain will affect their normal life, so some people will undergo ozone injection therapy. This treatment method is quite good, but there may be sequelae, some of which will affect the lives of the elderly. So, what are the side effects of ozone injection in the knee joint?

Ozone injection is usually used to treat knee pain, especially knee degenerative lesions. This condition is generally not harmful to the body and is a mature treatment plan.

1. What is knee synovitis?

It refers to a non-infectious inflammatory reaction disease caused by acute trauma or chronic strain of the knee joint, which causes synovial damage or rupture, leading to blood or fluid accumulation in the knee joint cavity. It can be divided into acute traumatic synovitis and chronic traumatic synovitis. Acute traumatic synovitis often occurs in young people who love sports; chronic injury synovitis often occurs in middle-aged and elderly people, obese people or those who over-load the knee joints.

2. Causes of knee synovitis

Acute synovitis often causes swelling, pain, difficulty in movement, limping, high local skin temperature, swollen and tense skin, and bloody fluid after joint puncture due to blow, twisting, excessive exercise, and 1 to 2 hours after surgery. This disease is often a complication of other knee joint injuries and must be differentiated from fractures, dislocations, ligament and meniscus injuries. Chronic synovitis is generally caused by the transformation of untreated acute traumatic synovitis, or by other chronic strains in the elderly that lead to synovial inflammation and exudation, resulting in joint effusion. It is more common in middle-aged and elderly people with a history of fatigue or joint pain. Patients may feel heavy legs, swollen joints, difficulty squatting, or pain going up and down stairs. The pain worsens after fatigue and exposure to cold, and improves after rest and when it is warm. With a long course of the disease, the quadriceps muscles will atrophy, the joints will be unstable, and movement will be limited. Joint puncture can extract light yellow, clear fluid. X-rays showed no obvious abnormalities or osteophyte formation in the bones and joint structure of the knee, but joint swelling and poor mobility were visible.

3. Treatment of knee synovitis

1. Massage therapy

(1) Pushing and kneading method: The patient lies on his back and kneads the knees from top to bottom along the tendons repeatedly for 1 to 2 minutes. (2) Extension and flexion of the knee: The patient's position is the same as above, with muscles relaxed. The doctor first gently flexes and extends the knee joint back and forth in a small range, and finally tries to fully flex the knee joint, and then straightens the affected limb. (3) Scraping and dividing tendons: The patient lies on his back and uses the flexed knuckle of one thumb to place it on the inside of the painful point above and below the patella. The other palm is placed on the flexed thumb and the arm strength is used to push the thumb outward and scrape several times. (4) When there is joint effusion, you can use hammering, pounding, and patting methods alternately. The punch is a solid fist, and the strike is an empty fist. Hit the soft tissue around the patella and the extensor side of the thigh. Flex and extend the calf 20 to 30 times each. The strike is a solid fist, and use the arm strength of both fists to press down on the same part as above, and repeat 1 to 2 times. Instead of using fists, use your palms to hit the back of your head and use the strength of your wrists to bounce the ball.

2. Piercing therapy

When there is a lot of joint effusion and tension is high, joint puncture can be performed to completely drain the effusion and blood, and sodium hyaluronate, which is the main component of synovial fluid, can be injected into the joint cavity. Studies have shown that various pathological changes in arthritis are closely related to its reduction and changes in physical and chemical properties. The injection of sodium hyaluronate has the following effects: covering the surface of articular cartilage, which can protect the articular cartilage and prevent or delay further degeneration; protecting the synovial membrane of the joint, removing pain-causing substances, and significantly reducing pain; improving the contracture state of the joint and increasing the mobility of the joint; and improving the synovial fluid of the degenerative joint.

3. Medication

In the acute phase of synovial injury and blood stasis, the treatment is mainly to disperse blood stasis, promote blood circulation and reduce swelling. Panax notoginseng powder can be taken orally. Chronic retention of water and dampness, and weakened muscles and tendons can be treated by dispelling wind and dampness, and strengthening muscles and tendons. Take Qianghuo Shengshi Decoction with modifications internally, and apply Gou Pi Gao externally. If the cold evil is more severe, you can also dispel the cold, wind and dampness, and use Wutou Decoction.

4. Immobilization and exercise therapy

In the early stage, you should rest in bed, elevate the affected limb, apply pressure with an elastic bandage, and prohibit weight bearing. During the treatment, quadriceps contraction and relaxation exercises can be performed, and in the later stage, knee flexion and extension exercises should be strengthened. This has a positive effect on eliminating joint effusion, preventing quadriceps atrophy, preventing recurrent synovitis, and restoring knee flexion and extension function.
