Kneecap Pain and Injury

Types of kneecap conditions

Types kneecap injuries and conditions include:

• Patellar fracture: This is a break in the patella. A broken kneecap is most commonly caused by a high-impact direct blow, such as a fall or a collision.
• Patellar dislocation: This is when the patella slips out of place. It is most commonly caused by a sudden twisting motion of the knee.
• Patellar tendonitis: This is an inflammation of the tendon that attaches the patella to the thighbone. It is most commonly caused by overuse of the knee.
• Patellar bursitis: This is inflammation of the bursa in front of the kneecap. When this bursa gets injured from a forceful impact or by overuse (excessive kneeling), the inflammatory response can produces excessive fluid, causing swelling that puts pressure on the surrounding areas of the knee, causing pain.
• Osteoarthritis of the kneecap: This is a condition in which the cartilage that cushions the knee joint wears away. It is most commonly seen in older adults.
• Patellofemoral disorders: These are conditions that affect the patellofemoral joint, where the kneecap meets the femur (thighbone).
