Dr. Markus Klingenberg demonstrates an ultrasound-guided knee injection using the patient’s own biological materials (like PRP or fat) as a regenerative treatment for osteoarthritis. He explains how he positions the patient, checks for fluid, and uses a no-touch technique to accurately place the needle into the suprapatellar fat pad. Ultrasound ensures the injection is precise and effective, which is important because many blind injections miss their target. His studies show this method can reduce pain and improve function for up to two years.
