Conditions Leading to Front Knee Pain
Front knee pain when bending and straightening can be caused by various conditions. Two common conditions associated with this type of knee pain are patellofemoral pain syndrome and osteoarthritis.
Patellofemoral Pain Syndrome
Patellofemoral pain syndrome, also known as runner's knee, is a common cause of knee pain characterized by pain at the front of the kneecap. This condition can be triggered by intense exercises like jogging, squatting, or climbing stairs. It occurs when the kneecap does not move correctly in the groove on top of the thighbone, leading to cartilage wear and pain [1].
Symptoms of patellofemoral pain syndrome include:
- Dull ache in the front of the knee
- Pain when climbing stairs, jumping, or squatting
- Discomfort after prolonged sitting
- Popping or crackling sounds when standing up or going up stairs [1].
Osteoarthritis
Osteoarthritis (OA) is a common type of arthritis that affects people over 50. It is characterized by the slow wearing away of cartilage in the knee joint. When this cartilage wears away, bone-on-bone contact occurs, resulting in pain, stiffness, swelling, and difficulty bending and straightening the knee [1].
Osteoarthritis is one of the most common causes of long-term knee pain, particularly in older individuals over the age of 65. The long-term damage to the cartilage in the knee joint leads to osteoarthritis, causing restricted movement, increased pain on weight-bearing, relief with rest, pain after periods of inactivity, and reduced stiffness with movement.
Symptoms of osteoarthritis in the knee may include:
- Stiffness
- Swelling
- Trouble bending and straightening the knee
- Worsening pain over time
- Feelings of weakness or buckling in the knee
- Increased pain in the morning or during rainy weather [1].
If you are experiencing front knee pain when bending and straightening, it is essential to seek a medical evaluation to accurately diagnose the underlying cause. Proper diagnosis is crucial for determining the most appropriate treatment options. To learn more about the diagnosis and treatment of knee pain, refer to the corresponding section in this article.
