Preparations for injection into the knee joint

Osteoarthritis of the knee joint periodically accompanied by pain and swelling.

To facilitate the patient's condition, doctors often use intraarticular injections as an emergency aid.

Which drugs and in what cases are injected into the knee joint - that's the topic of this material.

Preparations used for injection into the knee joint

As a rule, with gonarthrosis hormonal preparations of the corticosteroid group are introduced into the knee joint. This is Kenalog, Hydrocortisone, Diprospan, Celeston or Flosteron. Why are corticosteroids used in these cases? Because these drugs quickly and efficiently remove the pain syndrome and relieve inflammation in synovitis, that is, with swelling and swelling of the knee joints. The special popularity of corticosteroid injections among the prescriptions of doctors is explained by the speed of the therapeutic effect with which these funds operate.

In what cases are injections given in the knee joint?

The rapid and pronounced effect of corticosteroid preparations led to the fact that hormonal intraarticular injections began to be prescribed even if really necessary. For example, some zealous doctors prescribe hormonal injections only for prevention, to prevent the development of arthrosis. And meanwhile, just arthrosis is not treated with corticosteroid drugs, respectively, and to prevent its development, these funds are not able to.

Corticosteroids can not do the main thing - improve the joint cartilage, strengthen bone tissue and restore normal blood circulation in the joint. All that corticosteroids can do is to reduce, and at best remove the reciprocal inflammatory response of the body to damage in the joint cavity.

Hence the conclusion: to use intra-articular injections of hormonal drugs as an independent method of treatment is simply meaningless, only in complex therapy their use is justified and carries a certain therapeutic burden.

Examples when you need and when you do not need to take pricks in the knee joint

If the patient has a second degree of gonarthrosis with joint edema, it is likely that the fluid has accumulated in the joint - synovitis. Synovitis makes it difficult to carry out any medical procedures - gymnastics, manual therapy, physiotherapy. Therefore, in such a situation it is necessary to carry out intra-articular injection of a corticosteroid drug. The goal is to eliminate the synovitis in order to start active therapeutic measures in a week or two. This approach is correct.

If, however, the patient also diagnosed gonarthrosis of the second stage, but there is no accumulation of fluid in the joint and there is no swelling, then hormonal preparations do not make sense. Since there is no inflammation, it means that there is no point of influence for corticosteroids either.

Rules for the introduction of corticosteroids in the knee joint

  • But even with the real need for hormones, you need to adhere to a number of rules.

  • In the same joint, injections can be done no more often than once every two weeks. This is due to the property of the drugs to start "working" 10-14 days after the introduction. Therefore, to assess the effect immediately does not work.

  • The first hormonal injection into the knee joint brings real relief, but there will be no such effect in the future. Therefore, if the first injection has failed, it is natural that the result will not be either after the second, or after the third injection of the same drug in the same place. It is necessary or to change the drug, or choose a more precise place of injection. If in this case there is no result, then it is better to refuse the method of treatment of arthrosis of the knee joint with injections.

  • It is highly undesirable to inject corticosteroids into the same joint more than 4-5 times, as the risk of many side effects increases.
