Chondromalacia Patella

What is Chondromalacia Patella?

Chondromalacia Patella, also known as runner’s knee, is a condition characterized by the softening and degeneration of the cartilage on the underside of the kneecap. This cartilage, called the patellar cartilage, serves as a cushion between the thigh bone (femur) and the kneecap (patella). When it becomes damaged or wears down, it can lead to pain and discomfort during activities that involve bending or straightening the knee.

Causes

Several factors contribute to the development of chondromalacia patella. These include:

• Muscle Imbalance: Weakness or imbalance in the thigh muscles, particularly the quadriceps and hamstrings, can lead to abnormal patellar tracking.
• Overuse and Overloading: Repetitive stress on the knee joint, such as excessive running, jumping, or squatting, can contribute to the onset of chondromalacia patella.
• Trauma: Direct trauma or injury to the kneecap can cause damage to the cartilage, making it more susceptible to chondromalacia.
• Structural Abnormalities: Certain anatomical factors, such as flat feet, high-arched feet, or an abnormal alignment of the lower extremities, can increase the risk of developing chondromalacia patella.

Symptoms

The symptoms of chondromalacia patella can vary in severity, ranging from mild discomfort to significant pain. Common symptoms include:

• Knee Pain: The most noticeable symptom is pain around or beneath the kneecap, which is often aggravated by activities that involve bending the knee, climbing stairs, or sitting for prolonged periods.
• Crepitus: A grinding or popping sensation may be experienced when bending or straightening the knee.
• Swelling: In some cases, the affected knee may become swollen and tender to the touch.
• Weakness and Instability: Muscle weakness or a feeling of instability in the knee joint may be present, leading to difficulty with certain movements.
