What causes synovitis? How is synovitis of the knee caused?
The existence of things is reasonable, we now have more and more cell phone software library is the sports APP, a series of sports software, let us join the road, sports field, marathon “mob” ranks.
And with the promotion of the concept of national health, we see more and more people participating in various sports, running is the most popular.
This has made the once prosperous “low-headed people” stand up. From the vicious cycle of looking at the phone to the middle of the night – insomnia – get up and then look at the phone, to start to go out and brush the WeChat step count page leaderboard, nothing to run two steps?
But is running really the right sport for all people? The more you run, the healthier your body is? We also need to run according to our ability, after all, this is related to our health “knee and knee”.
The most important thing is to make sure that you have a good idea of what you are doing.
The most important thing is that you will be able to get the most out of your life. If this is seen by the next master Wang will not laugh at me, I have to walk 20,000 steps!”
Our results are often posted in our circle of friends to get praise to satisfy our vanity. But this often defeats the original purpose of exercise. Each person is unique, weight, height, body type, health, bone density, each person has different parameters, before running please design a set of exercise program for themselves. Otherwise, synovitis will come uninvited to let you know what “an arrow in the knee” pain.
Synovitis and cartilage damage are already on your mind!
Synovitis is a disease that many patients often talk about, and as long as the joint pain does not care what comes, consider whether you have synovitis. So what exactly is synovial membrane? What is synovitis? How is it diagnosed? What is the treatment? How to prevent it? Please listen to me.
What is synovitis?
The synovial membrane of the knee is a connective tissue membrane that consists of an inner lining and subsynovial tissue. The synovial lining is a synovial lining made up of 1 to 4 layers of loosely connected cells. Synovial cells are composed of A cells (macrophage-like cells) and B cells (fibroblast-like cells). A comes to engulf foreign bodies and is the main reason for the synovial reaction in our knee joints; B is associated with the synthesis and secretion of hyaluronic acid-protein in the joint.
If we compare the knee joint to a bearing, the synovial fluid secreted by our synovial membrane is like the lubricant for the bearing.
When our joints are stimulated by external injury or strain, this leads to a series of synovial reactions, such as the expansion of synovial vessels; the overflow of plasma and blood cells into the joint cavity and the active proliferation of synovial cells, which produces a large amount of mucus. When the rate of synovial exudation and absorption is dysregulated, these lesions lead to joint cavity effusion, increased intra-articular pressure and increased local concentration of endogenous pain-causing factors, and create a vicious cycle.
Eventually, the synovial fluid → effusion, significantly different from normal synovial fluid. Until the synovial membrane of the joint thickens or remains untreated. This is synovitis!
And synovitis is a “picky” disease, the knee is always his “Mr. Right”!
Some people ask, “Doctor, which age is more prone to the disease?”
Is it true that synovitis is more likely to occur in young people who are active? The answer is NO! Older people are even more susceptible because their synovial cells are less able to repair, produce less synovial fluid, and have less bone mass than young adults!
Synovitis of the knee in the elderly often refers to osteoarthritis with synovitis as the main pathological change, which is often the early manifestation of OA osteoarthritis, while advanced osteoarthritis is mainly manifested by the lesions of cartilage and subchondral bone.
When the knee joint swelling + knee swelling discomfort or swelling pain + floating patella test positive should go to the hospital for treatment.
Currently, the following tests are available for synovitis: X-rays, blood tests, MRI, and joint fluid tests. X-rays of the knee joint are necessary to rule out tumors or large organic lesions, and if necessary, an MRI may be needed to clearly visualize the synovial tissue and, in severe cases, to draw fluid from the joint cavity.
MRI can clearly show knee joint effusion and synovial thickening.
A floating patella test can be performed to check for fluid in the knee joint.
Treatment of early OA (synovitis)
There are several options for refrigerating this “elephant”
Let’s start with the conservative option: Move! Medicine! Suction! Flush!
Proper exercise: At one time, doctors have been emphasizing that the only way to completely treat osteoarthritis is to replace it with an artificial joint. But is this often our last resort, and do we just give up on this disease up front?
Of course not! Reducing exercise is not the same as not exercising; proper exercise is more likely to promote recovery. Theoretically, all stages I-IV osteoarthritis can be treated with exercise, while psychological conditioning and nutritional support can provide relief.”
Medication:Synovitis is divided into different types according to the inflammation: infectious & aseptic. The synovitis we often refer to is often aseptic, and you “mob” warriors please remember ~ aseptic does not require antibiotic treatment, please read the important thing in your mind three times!
The current drug treatment available: ① non-steroidal anti-inflammatory drugs such as fenbuterol, fotarine, etc.. The drug characteristics can inhibit the body inflammatory mediators to reduce the inflammatory response. Of course, please use the medication under the guidance of a doctor, to avoid long-term use of drugs leading to drug side effects in the gastrointestinal tract; ② promote lymphatic and venous reflux drugs such as Maizi Ling, elimination of the stop.
Aspiration of joint cavity fluid (not recommended): This method is often aimed at symptomatic treatment but often treats the symptoms but not the root cause. It is suitable for patients with a large amount of joint cavity fluid (the operation must be strictly aseptic to prevent sterile inflammation from becoming infectious inflammation).
Joint cavity injection irrigation therapy: the following methods are commonly used.
Sealing needle; is a certain concentration and volume of prednisolone injection and procaine hydrochloride (or their equivalent) mixed and injected into the lesion area. It acts as an anti-inflammatory and pain reliever, relieves spasm, etc.
Sodium vitrate + hormone flushing therapy: Sodium vitrate has a buffering and anti-inflammatory effect, and the injection of sodium vitrate has a strong inhibitory effect on the excitation of nociceptive receptors and sensory fibers of the synovial membrane, which can relieve joint pain.
Our “old friend” glucocorticoids can effectively relieve symptoms, but no one is perfect and no medicine is foolproof. They can cause irreversible damage to the articular cartilage, so be careful when using hormones to avoid hurting the enemy a thousand times.
PRP (Platelet Rich Plasma): A platelet concentrate extracted from whole blood, containing high concentrations of platelets, white blood cells and fibrin. When activated, platelets produce a variety of growth factors that are key to promoting synovial and cartilage repair.
Platelets are like patrol cars in the human bloodstream, once they find a broken house wall, they will stop at the accident site and release the construction workers in the car to find all kinds of materials, mud, cement, paint, and fix the wall again.
Like the NBA’s Kobe (Kobe), golf’s Tiger Woods (TigerWoods), the Prince of Tennis Nadal (RafaelNadal) …… after the injury, have chosen to PRP treatment.
What if conservative treatment doesn’t work?
Surgery: If after some of the above treatment still does not work, has progressed to severe osteoarthritis we really have no hope of knee? Of course not! Surgery is still an effective way to treat severe lesions.
Arthroscopy: Arthroscopic treatment has many benefits.
a. Simultaneous diagnosis and treatment;
b, early diagnosis and timely detection of the cause of simultaneous treatment;
c, less injury and complications, early activity, maximum maintenance of the knee function;
d. Arthroscopic treatment can be performed again for recurrence of synovitis;
e. For chronic synovitis of unknown etiology, arthroscopic synovectomy and flushing of the joint cavity can be performed. The clinical results are also more satisfactory.
HTO: Through high tibial osteotomy and correction of the force line, it is suitable for osteoarthritis of the knee with combined severe internal derangement, which can delay the progression of the disease preserving the normal function of the knee joint – called knee preservation treatment!
Unicondylar replacement (UKA): replaces only part of the medial joint surface, for patients with simple medial wear.
Total knee arthroplasty (TKA): replaces the entire joint surface, corrects the line of force, has a long prosthesis life, and relieves pain for sure. It is suitable for patients with severe cartilage wear of the entire knee joint and with inversion deformity.
How to prevent synovitis?
However, as the saying goes, treatment is better than prevention, and we can effectively prevent synovitis of the knee through our habits and behaviors in life:.
Avoid over-activity and strain on the knee joint;
Weight control, say no to obesity!
Exercise properly;
Keep warm;
Diet: Avoid excessive acid intake, and a balanced diet plays an important role in the prevention and treatment of synovitis. The elderly can take appropriate calcium and vitamin D supplements.
Before Exercise
In addition to adequate warm-up exercises, care should be taken to reduce the amount of exercise for the following positives.
Is the knee structure normal (normal lower limb force lines? O and X-leg?) ;
Are there any risk factors for articular cartilage damage (obesity, poor muscle strength, poor coordination);
Is there any chondromalacia of the kneecap?
Is there flat foot?
Other systemic conditions: cold, menstruation, etc.
When exercising
As the saying goes, “If you take a hundred steps after a meal, you can live for 99 years”. Every day, we take a few steps to the toilet, a few steps up and down the stairs, a few steps in the office …… but in addition to these fractional steps, every day can take 6000 steps in one breath is really able to improve everyone’s health. As long as the 6,000 steps to walk in one breath, long-standing adherence to the health condition will have qualitative improvement. And the best time to exercise is 8:00 to 10:00 in the morning.
After Exercise
Once the pain after exercise, there is no need to be nervous. If the pain is only when walking up and down stairs but not when walking flat: this means that it is only the early stage of knee injury, so we should avoid all sports or behaviors that cause joint injury to continue to worsen, and strengthen the rehabilitation of the joint. Avoid a vicious cycle.
And how should I pay attention to my posture when walking in normal times?
Let me tell you.
In short, the best way to exercise is to walk. But do not blindly “fight steps”, on the basis of health, consciously increase the pace, speed up the movement into life, increase calorie consumption, so that walking this “longevity medicine” to maximize the effect.
