What is a common physical exam finding in patients with osteoarthritis of the knee?

• A. Pain with each knee extension
• B. Crepitus during knee movement
• C. Areas of redness and warmth
• D. Excessive flexibility in the joint

Answer: (B)

A common physical exam finding in patients with osteoarthritis of the knee is crepitus during knee movement. Crepitus refers to the grating or popping sensation that occurs when the joint surfaces rub against each other due to the degeneration of cartilage. In osteoarthritis, the cartilage that cushions the joints gradually wears away, leading to irregular joint surfaces. As a result, patients often experience this distinctive sound or feeling, particularly during flexion or extension of the knee. This finding is indicative of the underlying joint changes associated with osteoarthritis, such as the development of osteophytes (bone spurs) and the roughening of the cartilage surface. It serves as an important clinical sign in diagnosing osteoarthritis, differentiating it from other types of joint issues that may present differently during physical examination.
