In modern medical practice, the technique of joint injections is often used. This method makes it possible to eliminate inflammation in the joints and prevent their deformation. Intra-articular injections into the knee joint are characterized by a certain risk efficiency, it depends on what drugs are used. The most popular and in demand are those that contain hyaluronic acid.
Hyaluronic acid is a core element of natural joint lubrication. It has a direct effect on the flexibility of cartilage tissue, thereby protecting it from abrasion. Due to the lack of hyaluronic acid, many joint ailments are formed in the body – the cartilage tissue weakens and eventually erases.
Thanks to the restoration of the degree of hyaluronic acid, the sliding of the cartilage plane improves and their flexibility increases. Hyaluronic acid restores the emollient properties in worn cartilage tissue, which beneficially affects the maneuverability of the joints.
If you start injections with hyaluronic acid in the first phase of the disease, you can get rid of manifestations of strongly manifested inflammatory processes. Hyaluronic acid is an excellent alternative to surgery and is the most effective way to recreate cartilage tissues in a short period of time.
What joints need hyaluronic acid for?
Hyaluronic acid is found in epithelial tissue, in connective and nerve fibers. This component exists in the composition of the liquid joints. It performs the function of preventing friction of the joint elements, which improves cushioning.
Hyaluronic acid acts as a lubricating component, and it makes movements smooth and prevents early tissue formation. If the synovial fluid is not enough or its composition is abnormal, the joint is able to collapse. This causes a decrease in motor amplitude.
Modification of the lubricant composition and number can be triggered:
- Excess weight;
- Hereditary predisposition;
- Excessive physiological loads;
- Age and so on.
When there is a so-called “drying” of the joints, the doctor often recommends the use of injections of hyaluronic acid. In medical practice, such therapy is used in such a disease as arthrosis. For example, for the knee joint hyaluronic acid is used in all cases, regardless of the cause. Moreover, it is prescribed in rehabilitation after arthroscopy or joint herbs.
What is the injection of hyaluronic acid?
Produced hyaluronic acid for joints as an injection and is a natural protector.
In the orthopedic industry means it is produced in several types:
- One is made from extracted animal tissue elements;
- The other is a synthesized product of specific microorganisms.
- Optimal genetic selection of colony forms gives the drug high-quality properties. Besides, allergic level synthetic the least.
Therapeutic properties of injections with hyaluronic acid
In the process of formation of the pathology of the tissue condition of the cartilage in the knee joint is experiencing atrophic/strain changes. Motor energy is difficult, and there are pains in humans due to the dismemberment and loosening of connective tissue fibers.
The injection of drugs furthermore in the knee immediately brings a number of beneficial effects:
- Improvement of the trophic tissue of the cartilage, creating fruitful conditions for the restoration of joint;
- Increasing the viscosity of the lubricant inside the joint, reducing the mutual friction of the joint surface in the process of motor activity;
- Warning inside the knee forming inflammatory reactions.
In particular, the effectiveness is noticeable when the knee joint has an initial stage of dystrophy. An important factor is that the presence of inflammation in the joint bag will make the injection of hyaluronic acid useless. Hyaluronic lose their properties if the patient has arthrosis, coupled with arthritis.
Thus, if the knee is inflamed, the primary anti-inflammatory treatment is carried out. And after her by injecting the hyaluronic acid. Reviews of such treatment only confirm the effect.
Thanks to the injection of hyaluronic acid into the joint is provided:
- Speeding up regeneration of tissue injury;
- Lubrication of the surfaces of the joints with a reduced content of synovial fluid;
- Minimization of cartilage stitching;
- The filling of the irregularities and cracks cartilage;
- Stimulating the body’s production of personal hyaluronic acid;
- Redistribution of tissue fluid during metabolism;
- Chondrocyte feeding;
- The increase of resistance of fabrics;
- A bunch of liquid that enters the joint cavity;
- Transformation in the gel water of the joints;
- Execution of the buffer function in the process of increasing the load on the joint or the effects of compression;
- Implementation of the barrier for synovial fluid;
- Reduction of inflammation.
Procedure and dosage
The standard procedure is the injection of hyaluronic acid is in the input means in the patient’s joint. Injections are carried out in the form of a course once in 7 days. In General, it varies from 3 to 5 injections.

Contraindication is only high sensitivity to hyaluronic acid. Often Hyaluronic acid is prescribed to elderly people. However, pregnant and lactating women it is prescribed only in extreme situations.
Contraindications to injections
Hyaluronic acid is well tolerated by most patients due to its physiological composition. However, there are contraindications to injections injected into the knee joint.
So, it is impossible to make a shot in the knee:
- The initial period of rehabilitation;
- High susceptibility;
- Strongly manifested inflammation process in the treated area.
Possible side effect
Injecting hyaluronic acid into the knee can bring side effects in the form of swelling and pain. For this reason, experts recommend for 2 days after injections in the knee to avoid significant physical exertion and great activity.
There are some concerns that can bring a shot of hyaluronic acid:
- It is impossible to make an injection into the affected joint;
- Bleeding may occur after injection, if the patient takes a drug that dilutes the blood.
In addition, patients with allergic reactions to eggs and birds should remember that a number of medicines with hyaluronic contain products of birds. In General, reviews about injections of hyaluronic acid in the knee are only positive.
What is a prick that replaces the natural lubrication of the joint?
The main effect of the treatment method by injecting Hyaluronic acid into the knee joint is to maintain the necessary amount of fluid to lubricate cartilage tissues. Thus, the occurrence of new injuries of the knee area is prevented.

Injections are made directly into the damaged place (joint). The duration of treatment is 14 days, during which 4 to 5 injections are administered. Secondary procedures are prescribed after a one-year break.
Injections are made from the following components:
- made of animal tissue elements;
- synthesized protector of microorganisms.
- With the introduction of injections, allergic reactions are practically excluded.
How is hyaluronic acid injection performed?
Before deciding on the injection, the doctor is likely to try to cure osteoarthritis in other ways:
- Prescription of pain medication;
- Corticosteroid injections;
- Physical therapy;
- Weight loss.
If these methods do not help, the injection of hyaluronic acid can bring the desired effect. Before the injection, the doctor may prescribe the following tests:
X-ray – to determine the severity of osteoarthritis;
Determine the presence of allergies to the components of the preparation of hyaluronic acid.
If you are taking any prescription drugs, over-the-counter drugs, herbs, and SUPPLEMENTS, tell your doctor, as some may interact with the components of the injection.
How long will it take to inject hyaluronic acid?
The procedure usually takes a few minutes.
