The Knee Joint. Jeannot Olivet / Getty Images. The knee is one of the most commonly injured joints in the body. The knee joint is the junction of the thigh and the leg (part of the lower extremity ). The femur (thigh bone) contacts the tibia (shin bone) at the knee joint. The patella (kneecap) sits over the front of the knee joint Method 2: Assess for fluid by placing one hand superior to the patella and with slight downward pressure milk the suprapatellar pouch which emptys into the knee joint. Next use the other hand to push to push on the patella. If there is an effusion, the patellar will bounce off the underlying bone (patella tap test)

Approaches to Aspiration or Injection of the Knee Joint. The first reported use of intra-articular (IA) corticosteroid in knee OA was by Hollander6) in 1953, and the first clinical trial of IA steroid use for knee OA was reported by Miller et al.7) in 1958.. Six major portals of approach to the knee joint for its aspiration or injection have been described: the lateral and medial mid-patellar. Arthrofibrosis (from Greek: arthro-joint, fibrosis - scar tissue formation) has been described in most joints like knee, hip, ankle, foot joints, shoulder (frozen shoulder, adhesive capsulitis), elbow (stiff elbow), wrist, hand joints as well as spinal vertebrae. It can occur after injury or surgery or may arise without an obvious cause. There is excessive scar tissue formation within the.

Prepatellar bursitis is an inflammation of the prepatellar bursa at the front of the knee. It is marked by swelling at the knee, which can be tender to the touch and which generally does not restrict the knee's range of motion.It can be extremely painful and disabling as long as the underlying condition persists Imaging . X-rays and other studies can assess alignment and loosening. Subtle loosening may not show up on a regular X-ray, and a bone scan or magnetic resonance imaging (MRI) scan may be performed. In addition, there are specialty imaging studies that can be performed specifically to assess for problems related to the knee replacement
Runner's knee is dull pain around the front of the knee. It may be caused by a structural defect, or a certain way of walking or running. Symptoms include pain, and rubbing, grinding, or clicking sound of the kneecap. Treatment includes not running until the pain goes away.

By using advanced digital imaging to precisely guide our injections, we remove the guesswork that many of today's practitioners rely on for your care Blood in the knee fluid is usually caused by either a torn anterior cruciate ligament (ACL) in the knee or a fracture of the bone and cartilage of the knee. When bleeding is the source of the swelling, the onset will be rapid and intense, usually within minutes. Non-bloody fluid can be caused by a ligament sprain or a meniscus tear in the rubbery disk that cushions the knee The unhappy triad, also known as a blown knee among other names, is an injury to the anterior cruciate ligament, medial collateral ligament, and meniscus.Analysis during the 1990s indicated that this 'classic' O'Donoghue triad is actually an unusual clinical entity among athletes with knee injuries The knee joint is a complex structure that involves bones, tendons, ligaments, muscles, and other structures for normal function. When there is damage to one of the structures that surround the knee joint, this can lead to discomfort and disability. Understanding the normal function of the knee joint can help you address some of these common. The articular capsule of the knee joint (commonly referred to as the capsular ligament) is the wide and lax joint capsule of the knee.It is thin in front and at the side, and contains the patella, ligaments, menisci, and bursae of the knee. The capsule consists of an inner synovial membrane, and an outer fibrous membrane separated by fatty deposits anteriorly and posteriorly
