Orthopedic injectables, also known as viscosupplements, hyaluronate injections, or chicken shots, are injectable gels made of hyaluronic acid or a similar substance. This may be naturally-sourced from chickens or created from bacterial fermentation in the laboratory, and the gel may also contain an anesthetic for pain relief.
In an aging or injured joint, the quality of this natural synovial fluid may degrade, and the cartilage may begin wearing down, causing friction in the joint. This results in pain, inflammation, and reduced mobility. Orthopedic injectables help by lubricating the affected joint and supplementing the synovial fluid to provide a cushioning effect. This reduces friction with movement, allowing the patient to use their joint with reduced pain. Doctors administer these injectables in their office or clinic.

Why do doctors use them?
Doctors may use orthopedic injectables to treat symptoms of osteoarthritis, such as pain and stiffness in the joints. The injections may help supplement or replace other osteoarthritis treatments, such as pain drugs, cortisone injections, and exercise, and the shots may also help delay the need for knee-replacement surgery.
Areas of use:
Patients usually choose orthopedic injectables to help relieve knee pain, but the injections may also be suitable for other synovial joints. This may include the hips, shoulders, ankles, or with lower volume injections, the finger, toe, and wrist joints.
How frequently should you use orthopedic injectables?
The number of orthopedic injections per treatment varies from product to product. Some treatments involve a single injection, some involve three weekly injections, and some involve up to five weekly injections. After this initial series of treatments, results usually last about six months, although Crespine Gel Plus results may last up to eight months.
How do doctors use them?
To administer these intra-articular injections, doctors first ensure the patient is positioned lying down with their knee straight or bent at a 20 to 30 degree angle. Once the knee or other joint is disinfected with alcohol or iodine, the doctor or nurse may apply an ultrasound to help find the correct placement, or the doctor may choose not to use the visual assistance of an ultrasound. After administering a local anesthetic if desired, and removing excess fluid if necessary, the doctor will inject the viscosupplement in the joint, just below the kneecap. The doctor may then request the patient flex their joint a few times to help evenly distribute the gel.
How long does the treatment take?
An orthopedic injection is a relatively-quick, in-office procedure. After preparation, the procedure itself may take as few as five minutes to complete.
Types of orthopedic treatments
These gels are made of sodium hyaluronate or similar substances which help lubricate and cushion the knee joint and treat knee osteoarthritis
These doctor-administered injections provide anti-inflammatory benefits, reducing joint inflammation and pain.
Oral pain relief and anti-inflammatory drugs can help control joint pain.
Exercise and Phisiotherapy
Low-impact exercise may help improve movement and reduce pain without putting extra strain on the affected joint.
Hot and Cold Therapy
Cold packs can help temporarily reduce inflammation and swelling while heat application can help temporarily relax muscles and improve circulation.
Braces and Devices
A brace may help take the load off an affected joint, a cane may help reduce excess stress on the joint, and orthotics in the shoes can help support the foot to reduce knee pressure.
Surgeries include a partial or total joint replacement, where the damaged cartilage is replaced with a prosthesis. With early intervention, surgery may help repair cartilage, meniscus, and bone.
Avoiding high-impact sports, reducing excessive bending, and not lifting heavy objects can help reduce pressure on the affected joint. Other drugs and supplements may also help ease osteoarthritis symptoms.
Where to buy orthopedic injectables
Viscosupplements can improve osteoarthritis symptoms, helping seniors and those with an injury regain their mobility, but the cost can be prohibitive for patients on a fixed income or tight budget.
