Your knees help you move through your day, whether you’re climbing stairs, getting up from a chair, or kneeling to tie a shoe. But when one of the small cushioning sacs inside your knee becomes inflamed, it can create uncomfortable symptoms that interfere with these simple tasks. This condition is called knee bursitis, and it often causes visible swelling and pain with movement or pressure.
Understanding what bursitis is and why it develops can help you manage it more effectively and get the right treatment if symptoms don’t resolve on their own.
Understanding Knee Bursitis
What Is a Bursa and Why Does It Matter?
A bursa is a small, fluid-filled sac that sits between bones and soft tissue near joints. Its main job is to reduce friction during movement. Your body has more than 150 bursae, and several of them are located around the knee.
When a bursa becomes irritated or inflamed, it can swell, fill with excess fluid, and become painful to the touch. In the knee, this often happens in the prepatellar bursa (just in front of the kneecap) or the pes anserine bursa (on the inner side of the lower knee).
Swelling can happen quickly or gradually, depending on the cause. It may look like a round bulge in front of the knee or feel like a thickened area near the joint.
Why Does Bursitis Happen in the Knee?
Knee bursitis often occurs due to overuse or repeated pressure on the joint. Common causes include:
- Frequent kneeling on hard surfaces (common in trades or gardening)
- A direct blow or fall onto the knee
- Poor joint alignment or movement patterns
- Repetitive squatting, lunging, or climbing stairs
- Infection within the bursa (less common but serious)
It’s important to note that bursitis is not the same as arthritis or tendonitis. Those conditions affect different structures. Bursitis involves inflammation of the cushioning sac itself, not the bone, cartilage, or tendons.
What Knee Bursitis Feels Like
People with bursitis in the knee may experience a mix of the following symptoms:
- Localized swelling at the front or side of the knee
- Pain when kneeling, squatting, or climbing stairs
- A feeling of pressure or tightness
- Tenderness to the touch
- Warmth or mild redness near the affected area
- Reduced range of motion if swelling limits bending
Some people also notice that their symptoms worsen at the end of the day or after certain activities.
How BOSH Physical Therapy Treats Knee Bursitis
Knee bursitis is a condition that BOSH Physical Therapy treats with a combination of hands-on care, movement retraining, and education. Our first step is to determine whether the swelling is due to bursitis or another condition. We then create a personalized plan to reduce inflammation and restore mobility.
- Manual therapy to decrease tension and improve joint mechanics
- Exercises that strengthen supporting muscles and improve alignment
- Guidance on activity modification to avoid further irritation
- Supportive taping or compression if appropriate
- Education on posture, kneeling strategies, and footwear
The goal is to relieve pressure on the bursa, reduce swelling, and restore safe, confident movement.
Helpful Strategies for Daily Relief
If your symptoms are mild, these at-home strategies may help you feel more comfortable:
- Use a knee pad if kneeling is unavoidable
- Elevate your leg after prolonged activity to help with fluid return
- Apply compression using a soft wrap (but not too tight)
- Avoid deep squats or stair climbing if they worsen the pain
- Gently move the knee through its range of motion without forcing it
If your swelling persists for more than a few days or starts to limit your activity, it’s a good idea to have it assessed by a professional.
