Iliotibial band syndrome (ITBS) is the second most common knee injury, and is caused by inflammation located on the lateral aspect of the knee due to friction between the iliotibial band and the lateral epicondyle of the femur. [2] Pain is felt most commonly on the lateral aspect of the knee and is most intensive at 30 degrees of knee flexion. [2]
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.
Infrapatellar bursitis is inflammation of the superficial or deep infrapatellar bursa. [3] Symptoms may include knee pain, swelling, and redness just below the kneecap. [2] It may be complicated by patellar tendonitis. [1] Risk factors include kneeling or crawling. [4]
Chondromalacia patellae (also known as CMP) is an inflammation of the underside of the patella and softening of the cartilage.. The cartilage under the kneecap is a natural shock absorber, and overuse, injury, and many other factors can cause increased deterioration and breakdown of the cartilage.
Symptoms may worsen if the knee is overly straightened or bent for too long a period. [2] Complications may include an inability to fully straighten the knee. [2] The underlying mechanism may involve bleeding, inflammation, or insufficient space for the fat pad. [2] This may occur as a result of trauma or surgery to the knee. [1]
PJI is estimated to occur in approximately 2% of hip and knee replacements, and up to 4% of revision hip or knee replacements. Other estimates indicate that 1.4-2.5% of all joint replacements worldwide are complicated by PJIs. [1] The incidence is expected to rise significantly in the future as hip replacements and knee replacements become more ...
Bursitis is the inflammation of one or more bursae (synovial sacs) of synovial fluid in the body. They are lined with a synovial membrane that secretes a lubricating synovial fluid. [1] There are more than 150 bursae in the human body. [1] The bursae rest at the points where internal functionaries, such as muscles and tendons, slide across bone ...
This inflammation is typically caused by the plica being caught on the femur, or pinched between the femur and the patella. The most common location of plica tissue is along the medial (inside) side of the knee. The plica can tether the patella to the femur, be located between the femur and patella, or be located along the femoral condyle.
