Where are the bursae around the knee?

Knee bursae Bursae reduce friction and cushion pressure points between your bones and the tendons, muscles and skin near your joints. Any of the bursa in your knee can become inflamed, but knee bursitis most commonly occurs over the kneecap or on the inner side of your knee below the joint.

Which bursa is most commonly injured?

All of the approximately 160 bursae in the human body are potentially susceptible to injury. The three upper-extremity bursae that are most commonly affected by bursitis are the subacromial, subscapular, and olecranon bursae.

What are the names of bursae associated with the knee?

The Main Knee Bursa

• Prepatellar Bursa. The prepatellar knee bursa is found directly in front of the kneecap, just underneath the skin.
• Infrapatellar Bursa. There are actually two infrapatellar knee bursa, known as the deep and superficial infrapatellar bursa.
• Pes Anserine Bursa.
• Semimembranosus Bursa.
• Suprapatellar bursa.

What is the bursa sac?

A bursa is a closed, fluid-filled sac that works as a cushion and gliding surface to reduce friction between tissues of the body. The major bursae (this is the plural of bursa) are located next to the tendons near the large joints, such as in the shoulders, elbows, hips, and knees.

What are the four anterior bursae of the knee?

There are four bursae anterior to the knee joint: subcutaneous prepatellar bursa: between the skin and patella. subcutaneous infrapatellar bursa: between the skin and tibial tuberosity. deep infrapatellar bursa: between patella ligament and upper tibia.

Is a bursa hard or soft?

A bursa is a small, thin, slippery sac filled with fluid. Bursae are located near joints, and they reduce friction between bone and surrounding soft tissue, such as skin, muscles, ligaments, and tendons.

Where is the Suprapatellar?

Suprapatellar bursa is located between the distal femur (leg bone) and the quadriceps tendon. It permits free movement of the quadriceps tendon over the distal femur. It allows for full flexion (bending) and extension (straightening) of the knee.

Is the Prepatellar Bursa part of the knee joint?

Prepatellar bursitis is an inflammation of the bursa in the front of the kneecap (patella). It occurs when the bursa becomes irritated and produces too much fluid, which causes it to swell and put pressure on the adjacent parts of the knee. (Left) Normal knee anatomy shown from the side.

Where are bursae found in the body?

Bursae are naturally present in the body and sometimes they are created by rubbing of body parts. They form to protect the area from trauma. Most of the bursae are located near the knee and shoulder joints. They are present near the major joints and are located adjacent to the tendons. They are also present in smaller joints, such as the toes.

Where are bursae located in the human body?

Synovial bursae, which are located between bones and muscles, tendons, and ligaments. Superficial bursa, which are located just below the skin, between skin and bone. Examples of superficial bursae include the patella bursa at the knee and the olecranon bursa at the elbow.

What are the symptoms of bursitis of the knee?

Localized swelling, warmth, and tenderness, as well as knee pain, often accompany bursitis of the knee. Bursitis is usually not infectious, but the bursa can become infected. Treatment of noninfectious bursitis includes rest, ice, and medications for inflammation and pain. Infectious bursitis is treated with antibiotics, aspiration, and surgery.

Where is knee bursa located?

This bursa of the knee is located just under the kneecap beneath the large tendon that attaches the muscles in front of the thigh and the kneecap to the prominent bone in front of the lower leg. This bursa is called the infrapatellar bursa, and when inflamed, the condition is called infrapatellar bursitis.
