Chondromalacia Patellae
Chondromalacia patellae, also known as runner's knee or patellofemoral pain syndrome, is a medical condition characterized by the softening and breakdown of the cartilage on the underside of the kneecap (patella). This condition can cause knee pain and tenderness, especially in individuals who participate in activities that put repetitive stress on the knee joint.
Causes and Risk Factors
The exact cause of chondromalacia patellae is not always clear, but several factors can contribute to its development. These include:
- Overuse or repetitive strain on the knee joint, such as from running, jumping, or cycling
- Abnormal tracking of the kneecap, where the patella does not move properly in its groove
- Weakened or tight thigh muscles, which can affect the alignment and movement of the kneecap
- Direct trauma to the knee, such as a fall onto the knee
- Foot problems, such as flat feet or high arches, that can affect the way the knee moves
Symptoms
The symptoms of chondromalacia patellae can vary from person to person but often include:
- Knee pain, usually in the front of the knee, which can be dull and aching or sharp and stabbing
- Pain when climbing stairs, squatting, or jumping
- Pain when sitting for long periods with the knee bent
- Grinding or clicking sensations in the knee when moving
- Knee swelling or inflammation
Diagnosis
Diagnosing chondromalacia patellae typically involves a combination of physical examination, medical history, and imaging tests. A healthcare provider may:
- Perform a physical exam to assess knee movement, alignment, and pain
- Take a medical history to identify any contributing factors or previous injuries
- Order X-rays or an MRI scan to evaluate the condition of the cartilage and other structures in the knee joint
Treatment
Treatment for chondromalacia patellae usually focuses on relieving pain, improving knee function, and addressing any underlying causes. This may include:
- Physical therapy to strengthen the thigh muscles and improve knee movement
- Pain relief medications, such as acetaminophen or ibuprofen
- Rest, ice, compression, and elevation (RICE) to reduce pain and inflammation
- Orthotics or shoe inserts to correct foot problems that may be contributing to the condition
- In some cases, surgery may be necessary to realign the kneecap or repair damaged cartilage
Prevention
To help prevent chondromalacia patellae, individuals can take several steps:
- Maintain a healthy weight to reduce stress on the knee joint
- Wear proper footwear and orthotics when engaging in physical activities
- Strengthen the thigh muscles through exercises like squats and lunges
- Avoid overuse or repetitive strain on the knee joint
- Warm up and stretch before exercising to reduce the risk of injury
Frequently Asked Questions (FAQs)

What causes Chondromalacia patellae?
May be caused by overuse, injury, or poor alignment of the kneecap, among other possible factors.
How is Chondromalacia patellae diagnosed?
Typically through physical examination, medical history, and imaging tests such as X-rays or MRI scans.
Can Chondromalacia patellae be treated without surgery?
Often treated with conservative measures such as rest, physical therapy, and pain management, but may require surgery in some cases.
What are the risk factors for developing Chondromalacia patellae?
May include overuse or repetitive strain on the knee, poor kneecap alignment, and certain underlying medical conditions.
Is Chondromalacia patellae more common in certain populations?
May be more common in young adults, athletes, and individuals who engage in activities that involve frequent jumping or running.
Can Chondromalacia patellae lead to other knee problems?
May increase the risk of developing other knee conditions, such as osteoarthritis, if left untreated or poorly managed.
What are some common treatments for Chondromalacia patellae?
May include physical therapy, bracing, pain management with medication, and in some cases, surgical procedures to realign or repair the kneecap.
Is it possible to prevent Chondromalacia patellae?
While not entirely preventable, taking steps to reduce knee stress and strain, such as maintaining a healthy weight and engaging in regular exercise, may help reduce the risk.
