Knee Bursitis

Knee bursitis is inflammation of a bursa—a small fluid-filled sac that cushions the knee joint. Learn about types, symptoms, and effective treatments.

What is Knee Bursitis?

Bursae are small, fluid-filled sacs that reduce friction and cushion pressure points between bones, tendons, and muscles near joints. The knee has several bursae, and any of them can become inflamed.

Knee bursitis can result from prolonged kneeling, a direct blow to the knee, overuse, infection, or conditions like gout or rheumatoid arthritis. While bursitis can be painful and limit mobility, it usually responds well to treatment.

Types of Knee Bursitis

Prepatellar Bursitis

Swelling in front of the kneecap. Common in people who kneel frequently ("housemaid's knee" or "carpenter's knee").

Location: Front of kneecap

Infrapatellar Bursitis

Affects the bursa below the kneecap. Often seen in jumpers and runners.

Location: Below kneecap

Pes Anserine Bursitis

Inflammation of the bursa on the inner side of the knee below the joint. Common in runners and overweight individuals.

Location: Inner knee below joint

Symptoms

  • Swelling over or around the knee
  • Warmth and tenderness in the affected area
  • Pain that worsens with movement or pressure
  • Stiffness and difficulty bending the knee
  • Redness over the swollen area
  • Pain when kneeling (prepatellar bursitis)

Warning: Septic Bursitis

Seek immediate medical attention if you experience:

  • • Fever or chills
  • • Significant redness spreading around the knee
  • • Severe pain with any movement
  • • Break in the skin over the swollen area

These may indicate infected (septic) bursitis, which requires urgent treatment with antibiotics.

Treatment Options

Most cases of non-infected bursitis resolve with conservative treatment.

Rest & Ice

Reducing activity and applying ice to decrease swelling

Compression & Elevation

Wrapping the knee and elevating to reduce swelling

NSAIDs

Anti-inflammatory medications for pain and swelling

Aspiration

Draining excess fluid if significant swelling is present

Corticosteroid Injection

For persistent cases not responding to other treatments

Antibiotics

Required if bursitis is caused by infection (septic bursitis)

Prevention Tips

  • • Use knee pads when kneeling for extended periods
  • • Take regular breaks during repetitive activities
  • • Maintain a healthy weight to reduce pressure on knees
  • • Stretch and warm up before exercise
  • • Address any underlying conditions that may contribute
