What Is Knee Bursitis?
Knee bursitis (also called pre-patellar or infrapatellar bursitis, and commonly called “housemaid’s knee, or clergyman’s knee) occurs when 1 or more of the many bursae (fluid-filled sacs) becomes damaged, irritated, or inflamed. Normally, a bursa acts as a cushion or friction-reducer between 2 body parts, such as between bone and skin, or bone and ligament or tendon. Bursae on the front of the knee serve as cushions between the knee cap and skin, and between the patellar tendon and tibia bone. Prolonged pressure or traumatic blows can injure a bursa, and repetitive motions can cause irritating friction on it, leading to the development of bursitis. is one of the most common bursitis conditions; it can be painful when moving the knee when kneeling, or even when at rest. The condition can also be painless, with only visible swelling present.
What Causes It?
The most common cause is trauma, whether from a direct hit, or the result of activities that require crawling or kneeling on hard surfaces for long periods of time, such as laying carpet or tile or scrubbing floors. Knee bursitis is most commonly seen in athletes; up to 10% of runners develop knee bursitis and manual laborers such as Construction Workers and Mason Workers. However, its occurrence is not related to any particular age or ethnic group, and can also be caused by infection or autoimmune conditions. Prolonged pressure or traumatic blows can injure a bursa, and repetitive motions can cause irritating friction on it, leading to the development of bursitis. In fact, “itis” means “inflammation.” When the bursa is injured, it can swell and become painful.
Knee bursitis can be caused by:
- Repetitive motions, including certain sports, such as running.
- Prolonged kneeling, as when cleaning floors, installing flooring, or praying in a kneeling position.
- Prolonged crawling, such as when laying carpet or flooring, or scrubbing floors.
- Direct trauma, such as being hit or falling on the knee.
- Knee surgery or knee joint replacement.
- Autoimmune conditions.
What Are The Symptoms, and How Is It Diagnosed?
With knee bursitis, you may experience:
- Swelling on the front of the knee
- Redness on the front of the knee.
- Pain when you push with your fingers on the front of the knee.
- Pain when kneeling.
- Stiffness in the knee joint or difficulty straightening or bending the knee.
If you see your physical therapist first, your therapist will conduct a thorough evaluation that includes taking your health history. Your physical therapist also will ask you detailed questions about your injury, such as:
- How and when did you notice the swelling and/or pain?
- Have you been performing any repetitive activity?
- Did you receive a direct hit to the knee, fall on it, or kneel for a long period of time?
Your physical therapist also will perform special tests to help determine the likelihood that you have knee bursitis. Your physical therapist will gently press on the front of the knee to see if it is painful to the touch, and may use additional tests to determine if other parts of your knee are injured. Your therapist also will observe how you can move your knee, and test your strength and flexibility.
Your physical therapist will test and screen for other, more serious conditions that could cause knee pain or swelling. To provide a definitive diagnosis, your physical therapist may collaborate with an orthopedic physician or other health care provider, who may order further tests to confirm the diagnosis and to rule out other damage to the knee, such as a fracture or infection.
How Can a SportsCare Physical Therapist Help?
Your SportsCare Physical Therapist will work with you to design a specific treatment program that will speed your recovery, including exercises and treatments that you can do at home. Physical therapy will help you return to your normal lifestyle and activities. The time it takes to heal the condition varies, but results can be achieved in 2 to 8 weeks or less, when a proper swelling management, stretching, and strengthening program is implemented.
During the first 24 to 48 hours following your diagnosis, your physical therapist may advise you to:
- Apply light compression to the area by wrapping the knee a specific way using a compressive wrap.
- Rest the area by avoiding any activity that causes pressure or pain in the knee.
- Apply ice packs to the area for 15 to 20 minutes every 2 hours.
- Consult with a physician for further services, such as medication or diagnostic tests.
Your physical therapist will work with you to:
Reduce Pain and Swelling. If repetitive activities have caused the knee bursitis, your physical therapist will help you understand how to avoid or modify the activities to allow healing to begin. Your physical therapist may use different types of treatments and electrothermal modalities (machines that use heat, light, or sound to reduce swelling and pain) to control and reduce your pain and swelling.
Improve Motion. Your physical therapist will choose specific activities and treatments to help restore normal movement in the knee and leg. These might begin with “passive” motions that the therapist performs for you to gently move your knee joint, and progress to active exercises and stretches that you do yourself.
Improve Flexibility. Your physical therapist will determine if any of your leg muscles are tight, start helping you to stretch them, and teach you how to stretch them on your own.
Improve Strength. If your physical therapist finds any weak or injured leg muscles, your therapist will choose and teach you the correct exercises and equipment to steadily restore your strength and agility.
Improve Endurance. Restoring your leg’s muscular endurance is important after an injury. Your physical therapist will develop a program of activities to help you regain the endurance that you had before the injury, so you can return to doing the things you like to do.
Improve Balance. Regaining your sense of balance is important after an injury. Your physical therapist will teach you exercises to improve your balance skills.
Restore Agility. Speed and accuracy of leg movement are important in athletics. Your physical therapist will help you regain these skills in preparation for a return to sports activities.
Learn a Home Program. Your physical therapist will teach you strengthening and stretching exercises to perform at home. These exercises will be specific to your needs; if you do them as prescribed by your physical therapist, you can speed your recovery.
Return to Activities. Your physical therapist will discuss your activity goals with you and use them to set your work, sport, and home-life recovery goals. Your treatment program will help you reach your goals in the safest, fastest, and most effective way possible. Your physical therapist will teach you exercises, work retraining activities, and sport-specific techniques and drills to help you achieve your goals.
Speed Recovery Time. Your physical therapist is trained and experienced in choosing the best treatments and exercises to help you safely heal, return to your normal lifestyle, and reach your goals faster than you are likely to do on your own.
