Knee osteoarthritis makes even the simplest everyday movements—such as walking, getting up from a chair, or climbing stairs—difficult.
Life Clinic Bergamo now offers a new treatment to reduce knee pain: polyacrylamide hydrogel, commonly known as a “liquid prosthesis.” It is a special gel, composed of 97% water, that is injected directly into the joint.
Unlike hyaluronic acid, which the body reabsorbs after a few months, this gel does not break down over time and has a long-lasting effect.
Once injected, it integrates into the knee's synovial tissue, helping to cushion impacts and improve the joint's range of motion.
It is important to know that it does not regrow damaged cartilage and is not a substitute for actual surgery. The term “liquid prosthesis” is used solely to explain its function, which is to relieve pain and restore mobility to the knee.
It is recommended for people with mild to moderate osteoarthritis who suffer from persistent knee pain or who have not benefited from physical therapy, traditional injections, or medication, and who do not yet require surgery to have a surgical prosthesis implanted.
A visit to an orthopedist is always necessary, along with an X-ray or MRI. This treatment is not suitable if there are active infections, skin infections at the injection site, or allergies to any of the components. In cases of very severe osteoarthritis, the feasibility of the treatment must be evaluated on a case-by-case basis.
The procedure is quick and is performed in a surgical clinic with a single puncture, often with the aid of an ultrasound machine, and under local anesthesia or mild sedation, depending on the patient’s medical history.
It is recommended that you avoid strenuous activity during the first few days, but you can resume your normal daily activities right away.
The results of clinical trials are very encouraging: many patients have reported reduced pain and improved mobility for several years following a single injection. This is an innovative option that should be discussed with an orthopedic specialist to determine whether it is the right choice for your needs.
