Bursitis is inflammation of a bursa located near your knee joint. A bursa is a small fluid-filled sac that reduces friction and provides a cushion between the bones, tendons and muscles near your joints. Our knees have 11 bursa each, and while any of these can become inflamed, knee bursitis most commonly occurs over the kneecap or on the inner side of your knee below the joint.
Knee bursitis can limit your ability to extend and flex your knee or stand without pain. Inflammation of any of the bursae in your knee may result in swelling, point tenderness or warmth around the knee joint. Kneeling is often difficult as well. Knee bursitis often comes on gradually but may follow an acute injury.
What to expect from therapy
Once it has been determined that the affected bursa is not infected, treatment may include a course of physical therapy. Your therapist may use a variety of interventions including modalities to decrease inflammation, exercises to improve strength and range of motion, and/or manual therapy techniques to address alignment and fascial issues. Instructions in long term self management strategies are essential to preventing future problems.
