Prepatellar bursitis, often called "housemaid's knee," is a painful condition affecting the bursa located just under the kneecap. This bursa is a fluid-filled sac that cushions the kneecap and reduces friction between the bone and overlying skin. While traditionally associated with those who kneel frequently, it's also common among athletes, particularly those engaging in sports involving repetitive kneeling or direct impact to the knee. This guide provides a comprehensive overview for patients seeking to understand, manage, and overcome prepatellar bursitis.
What is Prepatellar Bursitis?
Prepatellar bursitis is the inflammation of the prepatellar bursa, leading to pain, swelling, and tenderness around the kneecap. This inflammation can be caused by various factors, including repetitive kneeling, direct trauma (like a fall or blow to the knee), infection, or underlying medical conditions. The resulting discomfort can significantly impact daily activities and athletic performance. Understanding the causes and effective management strategies is crucial for a speedy recovery.
What Causes Prepatellar Bursitis?
Several factors can contribute to the development of prepatellar bursitis. Let's explore the most common causes:
Repetitive Kneeling:
This is a primary cause, especially in occupations requiring prolonged kneeling (hence the "housemaid's knee" moniker) and sports involving frequent kneeling such as wrestling or weightlifting. The constant pressure and friction on the bursa lead to inflammation.
Direct Trauma:
A direct blow or fall onto the knee can directly injure the bursa, causing immediate pain and swelling. This is common in contact sports like football or hockey.
Infection:
In some cases, prepatellar bursitis can be caused by an infection, often resulting from a wound or abrasion near the kneecap. The infection can spread to the bursa, leading to a more severe and potentially more complicated case. This septic bursitis requires prompt medical attention.
Underlying Medical Conditions:
Conditions like rheumatoid arthritis or gout can increase the risk of prepatellar bursitis by causing chronic inflammation in the body.
What are the Symptoms of Prepatellar Bursitis?
The symptoms of prepatellar bursitis are typically straightforward and often noticeable immediately following an injury or after prolonged kneeling. These include:
- Pain: Pain is often the most prominent symptom, localized to the front of the knee, directly beneath the kneecap. The pain is typically worse with kneeling, pressure, or movement.
- Swelling: The knee will appear swollen and may feel warm to the touch. The swelling can vary in severity depending on the extent of the inflammation.
- Tenderness: The area around the kneecap will be tender to the touch.
- Redness: The skin over the bursa may appear red and inflamed, particularly in cases of infection.
- Limited Range of Motion: In severe cases, the inflammation can restrict the knee's range of motion, making it difficult to bend or straighten the leg fully.
How is Prepatellar Bursitis Diagnosed?
Diagnosis of prepatellar bursitis usually involves a physical examination by a healthcare professional. They will assess the knee for swelling, tenderness, and warmth. A visual inspection will often suffice, but additional tests might be necessary to rule out other conditions or identify an infection. These might include:
- Aspiration: A needle is used to withdraw fluid from the bursa for analysis. This can help determine if there's an infection.
- Imaging Studies (X-rays): While less often necessary, X-rays can rule out other knee problems like fractures.
How is Prepatellar Bursitis Treated?
Treatment for prepatellar bursitis depends on the severity of the condition and its underlying cause. Common treatments include:
- RICE Method: Rest, ice, compression, and elevation are essential initial steps. Resting the knee, applying ice packs regularly, using compression bandages, and elevating the leg helps reduce swelling and pain.
- Nonsteroidal Anti-inflammatory Drugs (NSAIDs): Over-the-counter pain relievers like ibuprofen or naproxen can help manage pain and inflammation.
- Corticosteroid Injections: In more severe cases, a doctor might inject corticosteroids directly into the bursa to reduce inflammation quickly.
- Aspiration: If an infection is suspected, aspiration (removal of fluid) will be performed. Antibiotics are crucial in treating septic bursitis.
- Surgery: Surgery is rarely needed and is usually reserved for cases that don't respond to other treatments or those involving chronic, recurrent infections.
How Long Does it Take to Recover from Prepatellar Bursitis?
Recovery time varies depending on the severity of the condition and the individual's response to treatment. Mild cases might resolve within a few weeks with conservative management, while more severe cases or those involving infection could take several months. Consistent adherence to the treatment plan is vital for a successful recovery.
Can Prepatellar Bursitis Be Prevented?
While some causes of prepatellar bursitis are unavoidable (e.g., a direct blow), several preventative measures can reduce the risk:
- Proper Padding: Using knee pads during activities that involve repetitive kneeling, such as gardening or certain sports, can offer protection.
- Appropriate Footwear: Wearing supportive footwear can improve stability and reduce the stress on the knees.
- Regular Stretching and Strengthening Exercises: Strengthening the muscles around the knee improves support and stability, lessening the burden on the bursa.
- Maintaining a Healthy Weight: Excess weight puts additional stress on the knees, increasing the risk of bursitis.
When Should I See a Doctor?
You should seek medical attention if you experience:
- Severe pain
- Significant swelling
- Redness and warmth around the knee
- Signs of infection (pus, fever)
- Inability to bear weight on your leg
- Symptoms that don't improve after a week of home treatment
