Bursitis Knee: Causes, Signs & Treatment of Prepatellar Bursitis
Prepatellar bursitis, also known as kneecap bursitis, is a common inflammation of the prepatellar bursa sac, the fluid-filled sac that covers the front of the kneecap. Bursitis occurs when one of the bursa sacs becomes inflamed or damaged. These small sacs help reduce friction between tissues such as tendons and bones. The prepatellar bursa sac specifically reduces friction caused by movement between the kneecap and the skin. Kneecap bursitis results in pain and swelling at the front of the knee. Most cases of prepatellar bursitis can be treated at home with rest.

What is Prepatellar Bursitis?
Your knee contains several bursae that help cushion it from damage. These fluid-filled sacs protect the bones and soft tissues of the knee. Another important bursa in the knee is the suprapatellar bursa. Normally, these structures lay flat against your skin and bones, and you do not notice them.
However, when a bursa becomes irritated, damaged or infected, it can become inflamed and produce excess fluid, causing pain and visible swelling in the knee. Kneecap bursitis may cause the knee to appear swollen or bulging. Due to its prevalence in professions that involve frequent kneeling, prepatellar bursitis is also referred to as housemaid’s knee, carpet layer’s knee, coal miner’s knee or carpenter’s knee. Long-term irritation or damage can lead to chronic inflammation of the bursa, often described as knee bursitis.

What Causes Prepatellar Bursitis?
Chronic prepatellar bursitis results from repeated overuse or pressure on the knee, such as frequent kneeling. Occupations or activities that require kneeling can increase your risk. Those with rheumatoid arthritis or gout may also be predisposed to developing bursitis. Gout is caused by a buildup of uric acid and uric acid crystals in the joint, leading to inflammation and pain.
The acute form of prepatellar bursitis typically results from trauma, such as a forceful impact on the knee or an infection. Sports injuries and falls can also trigger bursitis. In cases of infection, bacteria can enter the bursa fluid, resulting in an infected bursa.
Less common is infectious prepatellar bursitis, which occurs when a wound to the knee allows bacteria to enter the bursa. This can result in septic bursitis, a serious condition that requires prompt medical attention.
Who is at Risk? (Risk Factors for Prepatellar Bursitis)
Prepatellar bursitis can affect people of all ages, but certain groups are more likely to develop this condition. Individuals whose jobs or hobbies involve frequent kneeling are at higher risk due to the repeated pressure placed on the knee. Athletes who participate in sports that involve direct contact with the ground, like wrestling or football, are also more susceptible.
People with underlying health conditions such as rheumatoid arthritis or gout are more prone to developing bursitis, as these conditions increase inflammation in the knee. A history of knee trauma or previous knee surgery can further elevate the risk, making it important for these individuals to take extra precautions to protect their knees.
Prepatellar Bursitis Symptoms
Common symptoms include pain with movement, swelling at the front of the kneecap and tenderness in the knee. Prepatellar bursitis caused by infection may also produce fluid, redness, fever and chills.
The onset of prepatellar bursitis may be sudden in cases of acute injury, while chronic symptoms can develop gradually over time. In severe cases, symptoms may include significant swelling, redness and difficulty moving the knee.
How is Prepatellar Bursitis Diagnosed?
Prepatellar bursitis is typically diagnosed through a physical examination. To make an accurate diagnosis, your Resurgens physician will ask about your symptoms, medical history and activity level. They will examine your knee for pain, swelling and signs of infection, and test your range of motion.
Your physician may recommend imaging tests such as an X-ray, MRI or CT scan to determine if an injury to the knee or surrounding soft tissue is contributing to your condition. If infection is suspected, they may withdraw fluid from the bursa using a procedure called aspiration to analyze it for infection.
Prepatellar Bursitis Treatment
Conservative treatments are usually recommended first for kneecap bursitis.
Treatment options include rest, applying ice to reduce swelling and taking anti-inflammatory medications. Using an ice pack, such as a bag of frozen peas wrapped in a towel, can help manage symptoms by reducing inflammation in the bursa. Patients should avoid kneeling or use knee pads when possible.
Your Resurgens physician may drain fluid from a swollen bursa to help the knee heal, and in some cases, a steroid injection may be used to reduce inflammation and fluid buildup.
Bursitis caused by an infection may require antibiotics. If these methods are not successful, surgery may be necessary, though surgical intervention is rare.
Non-Surgical Prepatellar Bursitis Treatment
Home remedies play an important role in non-surgical management, helping relieve symptoms before medical intervention is considered.
Kneecap bursitis typically improves without surgery if no infection is present. Non-surgical treatment focuses on symptom relief:
- Avoid activities that exacerbate knee pain.
- Apply ice to the affected knee three to four times a day for 20 minutes.
- Elevate the affected leg when possible.
- Use nonsteroidal anti-inflammatory drugs (NSAIDs) such as naproxen or ibuprofen to relieve pain and reduce inflammation. Acetaminophen can be used if NSAIDs are not tolerated.
- Physical therapy or bracing may also be recommended.
Surgical Prepatellar Bursitis Treatment
If non-surgical treatments are ineffective, your physician may recommend:
- Draining the bursa (aspiration) and injecting a corticosteroid to reduce inflammation.
- Surgical removal of the bursa.

Preventing Prepatellar Bursitis
Taking proactive steps can help prevent prepatellar bursitis and keep your knees healthy. If your work or activities involve frequent kneeling, wear knee pads or use cushioned mats to reduce pressure on the prepatellar bursa. Maintaining a healthy weight also helps, as excess weight increases strain on the knee joint.
Incorporate regular breaks to rest and stretch your knees during prolonged kneeling or standing. Before physical activity, warm up and cool down properly to protect the soft tissues around your knee. By following these strategies, you can help prevent bursitis and keep your knees functioning at their best.
Possible Complications and Future Risks
While prepatellar bursitis often responds well to treatment, ignoring symptoms or delaying care can lead to complications. Chronic bursitis may cause ongoing pain and swelling that interfere with daily activities. In rare cases, infection can lead to septic prepatellar bursitis; a serious condition requiring immediate medical attention. Persistent inflammation may also increase the risk of developing other types of bursitis, such as pes anserine bursitis, which affects a bursa on the inner side of the knee.
If your symptoms do not improve or worsen, seek prompt treatment to protect your knee health.
Recovery and Rehabilitation After Prepatellar Bursitis
Recovery typically involves rest, ice, compression and elevation (RICE) to reduce pain and swelling. Physical therapy is often recommended to restore range of motion and strengthen the muscles supporting the knee joint. Your healthcare provider may also suggest medications to manage pain and reduce inflammation.
Most people experience improvement within a few weeks, but it’s important to follow your treatment plan and avoid returning to aggravating activities until your knee has fully healed. With proper care and rehabilitation, you can expect to regain normal function and return to your usual activities.
Lifestyle Modifications for Long-Term Knee Health
Adopting healthy habits can protect your knees and reduce the risk of bursitis and other knee problems. Maintaining a healthy weight helps minimize stress on the knee joint, while regular exercise keeps supporting muscles strong and flexible. If your routine involves frequent kneeling, try to limit this activity or use protective gear like knee pads.
Wearing supportive footwear and considering orthotic devices can help distribute pressure more evenly across your knees. Taking regular breaks to stretch and rest your knees during prolonged activity also prevents overuse injuries. Consulting a physical therapist or orthopedic specialist can help you develop a personalized plan to keep your knees healthy and prevent bursitis from returning.
