Clinical Trial Tests an Investigational Injection for Knee Osteoarthritis

Knee osteoarthritis involves changes in cartilage and other joint tissues that can cause pain, stiffness and difficulty with walking, climbing stairs or standing for long periods. Treatment depends on symptom severity, function, other medical conditions and the patient's goals. Researchers at Keck Medicine of USC are evaluating an investigational injection designed for knee osteoarthritis. Early clinical testing generally assesses whether a treatment can be administered safely and whether there are adverse effects that require closer examination. Additional trial stages may be needed to determine how well the treatment relieves pain, how long any benefit lasts and how it compares with existing care. The launch of a trial does not mean the injection is approved for routine use or that it will work for every patient. Patients interested in investigational treatments should ask about eligibility, possible risks, alternative therapies and whether participation requires changes to their existing care. Current management may include tailored exercise, physical therapy, weight management where appropriate and clinician-recommended medicines or procedures. Persistent swelling, severe pain or an inability to bear weight warrants medical assessment.
