What conditions can lead to "runner's knee"?

• A. Osteoarthritis and ligament tears
• B. Patellofemoral pain syndrome and excessive strain
• C. Meniscus tears and patellar dislocations
• D. Fractures and traumatic injuries

Answer: (B)

"Runner's knee," medically known as patellofemoral pain syndrome, is primarily associated with conditions that result from overuse or excessive strain on the knee joint. This syndrome is characterized by pain around the kneecap, often exacerbated by activities such as running, squatting, or climbing stairs. The correct answer highlights patellofemoral pain syndrome directly, as it is a common condition in runners and athletes. Excessive strain on the knee can occur due to several factors, including overtraining, improper footwear, biomechanical issues such as misalignment of the kneecap, and muscle imbalances. These elements contribute to irritation and pain around the kneecap and are central to the diagnosis of runner’s knee. In contrast, while osteoarthritis, ligament tears, meniscus injuries, patellar dislocations, fractures, and traumatic injuries can all affect the knee, they do not specifically describe the common mechanisms that lead to runner's knee. Hence, they are less relevant to the direct cause of the condition described in the question. This is why the option focusing on excessive strain and patellofemoral pain syndrome appropriately addresses the conditions that lead to "runner's knee."
