Causes of kneecap pain:
1. Trauma or injury: Direct impact, sprains, or falls may cause kneecap pain. This situation is common among athletes, sports enthusiasts, or elderly individuals after accidental falls.
2. Degenerative joint disease: Such as osteoarthritis, which results from gradual wear of the joint cartilage, leading to increased friction between bones and causing pain, stiffness, and functional impairment. This is usually a result of aging, overuse, or genetic factors.
3. Osteoporosis: A common bone disease among middle-aged and elderly individuals, characterized by reduced bone formation and increased bone resorption, leading to increased bone fragility and susceptibility to fractures. Osteoporosis may also cause kneecap pain, especially noticeable during weight-bearing or physical activity.
4. Overuse: Prolonged repetitive movements or activities, such as running or jumping, can lead to overuse syndrome of the knee, causing pain.
5. Patellar problems: Such as patellar dislocation or chondromalacia patellae, which affect the small bone in front of the knee joint—the patella—and cause pain.
