Orthopaedist Dr. Sven Ostermeier Discusses Patellofemoral Osteoarthritis and Cartilage Wear
Orthopaedist Dr. Sven Ostermeier highlights patellofemoral osteoarthritis as a common cause of noisy and stiff knees, particularly in individuals aged 50 and older. This condition involves the breakdown of cartilage on the underside of the patella (kneecap) and the groove of the femur (thighbone). The kneecap is crucial for extending and straightening the leg, and when its cartilage wears away, the resulting friction can cause pain and audible crunching sounds. Dr. Ostermeier emphasizes that degenerative changes behind the kneecap are the root cause and should be addressed early to prevent progression. Symptoms can include stiffness, a feeling of the knee locking up, and, if inflammation occurs, swelling and warmth in the kneecap region. The condition is often exacerbated by activities like descending stairs or inclines, standing from a sitting position, kneeling, or squatting.
