Knee Injections in Dallas/Fort Worth – Avoid Surgery
These are useful for treating flare-ups of osteoarthritis pain and swelling. This is where fluid builds up in the knee. Symptoms are alleviated when inflammation in the joint is reduced with the medication injected. The medicine works rapidly, giving relief for 24 to 48 hours after the injection. Also, the benefit is only short-term, lasting from 6 to 12 weeks. A corticosteroid shot works best the first time, but may need to be repeated every three to four months.
Hyaluronic Acid Injections
A healthy knee has plenty of synovial fluid that allows it to move smoothly. When the fluid thins and goes away, the doctor can inject hyaluronic acid into the knee to allow it to glide smoothly with movement. Research studies show that these injections allow for pain-relief for people with osteoarthritis. The doctor will use hyaluronic acid shots to someone who has failed on other treatments, such as nonsteroidal anti-inflammatory drugs (NSAIDS), acetaminophen, and steroid shots. The hyaluronic acid cushions and lubricates the joint, but the effects are only short term.
A new treatment for knee osteoarthritis and joint problems is platelet-rich plasma (PRP). This measure requires drawing a sample of the patient’s own blood and processing it so the fluid is platelet-rich. These tiny disks help clot the blood, and are injected back into the injured area. Blood platelets have natural chemicals that help heal injuries, such as tendon and ligament damage.
Synvisc-One is an injection used to provide the knee joint with fluid to cushion and lubricate the joint. This therapy is marketed to give six months of osteoarthritis knee pain relief to a patient. The joint fluid (synovial fluid) will break down over time and wear away. Synvisc supplementation is used to replenish this fluid. A Synvisc injection is a gel-like mixture that is made of hyaluronan, which comes from chicken combs. This product acts as a lubricant and shock absorber in the affected joint.
Another type of knee injection is Orthovisc, which is an anti-inflammatory treatment recommended for patients with knee arthritis. This is used by doctors to reintroduce healthy joint fluid into a damaged knee joint to allow normal movement and function.
An arthrocentesis is a knee injection done to remove fluid from the knee and instill steroid medication and lidocaine into the joint. This procedure helps establish a diagnosis, drain excessive fluid from the knee, and treat the joint. Prompt treatment of a joint infection via arthrocentesis can alleviate joint discomfort and complications. The knee often develops effusions, which causes suprapatellar and parapatellar swelling.
The Knee Injection Procedure
The patient is positioned supine with the knee extended. The knee is examined and the skin is marked with a pen pointing to the most direct access to the synovium. After being cleansed with povidone-iodine solution, the physician will inject a needle into the side of the knee. Once this is done, the medication will be instilled or aspiration is performed, depending on the procedure. After the procedure, the skin is cleansed and a bandage is applied over the puncture site. The patient is advised to avoid physical activity per doctor’s instructions.
