Knee Injections to Replace Cartilage Tissue Cells

During osteoarthritis, non-operable methods of direct injection of synovial fluid into the knee protection and partial recovery of cartilage tissue cells can be used.

A medical professional may suggest injections as a treatment for osteoarthritis, an inflammatory condition of joint cartilage and bone.
When knees ache, stiff, and swollen from osteoarthritis, several treatment alternatives are available.

Treatment for osteoarthritis (OA) of the knee may begin with non-medicinal interventions, such as workout or weight reduction. Another choice is over the counter (OTC) pain relief medication. Choices consist of acetaminophen (Tylenol), aspirin, or ibuprofen (Motrin, Aleve).

When oral medications do not relieve knee pain, however you’re not to the point of pursuing knee surgery, among the following injections may help.

If these treatments do not deal with symptoms, injections are available to assist achieve the wanted results. The United States Food and Drug Administration (FDA) has actually authorized two injections to treat OA of the knee: Hyaluronic acid and corticosteroids.

Hyaluronic Acid Injections

Hyaluronic acid is a gel-like compound that is naturally present in the synovial fluid surrounding the joints during OA.

Hyaluronic acid injections into the knee compensate for the lack of synovial fluid in the knee to preserve and protect the cartilage tissue.

This compound provides lubrication and cushioning. It functions as a shock absorber and helps the bones move smoothly instead of grinding against one another.

Individuals with OA have lowered quantities of hyaluronic acid in their joint fluid. Hyaluronic acid injections can help restore normal levels. These injections not only oil the joint, however they might also decrease inflammation and protect the cartilage from further wear and tear.

A doctor or another doctor will inject in between one and 5 shots into the knee. The variety of shots depends on the brand of hyaluronic acid. Injections take place at weekly periods.

Before offering an injection, the medical professional may perform an aspiration, removing some of the fluid from the knee joint with a needle to lower swelling.

After injections, avoid putting too much weight on the knee. Do not jog or run, mean extended periods of time, or lift heavy things.

Side effects

Common negative effects from hyaluronic acid injections include:

  • pain in the knee
  • bruising
  • heat
  • small swelling

These adverse effects must deal with after a few days. Using a bag of ice to the knee can assist relieve pain and prevent swelling after the shots.

The pain relief results of the injection generally last for about 6 months. Once this disappears, an individual will need another round of shots or various treatment.

Many insurers will cover the second round of injections if they also covered the initial treatment, and it assisted ease the pain.

Hyaluronic acid injections do not stop or reverse arthritis. Nevertheless, they may momentarily alleviate pain and improve movement in some people. Those with mild OA are likely to see the best gain from hyaluronic acid injections.

Corticosteroid Injections

Steroid medications act in a similar way to the hormone cortisol. Cortisol deals with the body immune system to minimize inflammation throughout the body, likewise serving to relieve pain.

From here it can be understood that the injections of steroids is not aimed to replace cartilage tissue, but fights directly with pain in the joint.

The FDA have actually authorized 5 different steroid medications to treat OA. All of them have to do with equally effective.

The FDA have also just recently approved an extended release corticosteroid injection of triamcinolone acetonide (Zilretta). An individual can have it just when, however its anti-inflammatory results might last longer.

Individuals will need to check out a physician for the injection. Medical professionals often utilize ultrasound to guide the placement of the needle into the area around the joint. Ultrasound is a scan that uses acoustic waves to create pictures of the within of the body.

The physician might likewise offer an injection of anesthetic pain relief together with the injection, which will provide instant relief. The steroid must begin taking impact within a few days.

Corticosteroids work faster than hyaluronic acid injections, however their effects do not last as long. In some people, corticosteroid injections can assist alleviate pain and enhance movement in the joint. Others do not find any pain remedy for these shots.

People with a comprehensive damage in the knee are less likely to see outcomes. Even if the pain does enhance, it might begin to return from a few weeks to a few months after the shot.

Side effects

Although the FDA thinks about corticosteroid shots to be safe, people may experience adverse effects, such as:

  • crystal flares, or irritation in the joint similar to gout
  • nerve damage
  • in rare cases, infection
  • an increase in blood sugar level levels, an adverse effects especially typical in individuals with diabetes
  • thinning of the bones near the knee

If the impacts subside, individuals receiving the injection may not have the ability to have another shot right now. Doctors only suggest getting corticosteroid injections once every 3-4 months.

Getting shots too frequently can increase the threat of negative effects, such as damage to soft tissues in the knee. The pain relief from the injection will also not be as reliable and diminish more quickly.

If injections every couple of months are not regular adequate to alleviate the pain, another kind of treatment may be essential.


Apart of injecting Hyaluronic acid and corticosteroids into your knee to replace/build up cartilage tissue cells, arthrocentesis also very popular solution for your knee joints.

Likewise called joint fluid aspiration, arthrocentesis is removal of joint fluid through a hollow needle placed into the joint area of the knee. Although the function of getting rid of joint fluid from the knee is generally so that it can be checked in the lab, eliminating excess fluid can also rapidly ease pain and swelling. Often after withdrawing fluid, medical professionals utilize the exact same leak site where the fluid was gotten rid of to inject a corticosteroid preparation and/or anesthetic into the knee joint to further alleviate pain and inflammation.
