Patella

The articulations that form the nee are between the patella, tibia, and femur. The tibiofemoral articulating surface is made up of the lateral and medial condyles of the femur that articulate with the tibia (Marieb & Hoehn, 2007). The tibiofemoral joint is mainly the joint which bears the weight of a person…

Introduction Patellar dislocation occurs when your kneecap (patella) slips out of its normal position. The patella is located in a groove in front of the lower end of your thighbone (femur). This groove is called the patellofemoral groove. It usually occurs toward the outside of the leg. What are the causes? This condition is caused by: Force. Sports injuries. Twisting the knee when the foot is planted. What increases the risk? This condition is more like to occur in: Women. People who play…

also slowly increased since her injury due to her low back pain. On examination of the right knee, the patient flexed, extended and internally rotated her log several times and the patella slipped into place, with an audible pop. Right knee is tender to palpation along the medial jointline and the lateral patella. Patella is palpated lateral to the patellar groove. Range of motion is decreased in flexion due to pain along the lateral patellar aspect. Chondromalacia patellar compression test and…

of the most complex and important hinge type synovial joints, and the largest joint in the body. It has two articulations, one with the femur and the tibia, and the second with or between the femur and patella, or knee cap. The knee is made up of four bones; the femur, tibia, fibula, and the patella. These four bones give the knee stability, strength, and flexibility. The femur is the single bone of the thigh, it the largest and longest and strongest…

variety of anatomical factors including abnormal trochlea and patella, poor alignment of the lower limb, and poor static and dynamic patellofemoral stabilizers. Lateral patellar dislocation typically involves a history of patellofemoral instability with a twisting event while…

Throughout the Fall Semester I suffered from multiple injuries that affected my academics and attendance. In the beginning of the semester I experienced a dislocation of my left patella. This caused me pain during that month, which interfered with my attendance. On days that I didn’t suffer from knee inflammation I would be able to attend class. Following that I suffered from a severe concussion and a broken nose.The doctors preferred me to not do anything that made me concentrate or use my…

Total knee replacement is also known as total knee arthroplasty (Scott, 2015). The reasons for having this arthroplasty (reconstruction of a joint) done include severe knee pain, and stiffness that limits the patient’s ability to walk (Phillips, 2013; Scott, 2015). This procedure relieves pain and helps the patient regain function of the knee by replacing three knee joints, the medial and lateral femorotibial joints, and the patellofemoral joint (Scott, 2015). When the patient is supine, the…

The major pitfalls in MR imaging of knee are due to anatomic variants and artefacts, especially partial volume effects. ( 40 ) Understanding the basic MR imaging principles, applying the correct technique, knowing the normal anatomy and variants, recognizing artifacts, and assuring good clinical and radiographic correlation helps avoid these potential pitfalls. ( 41 ) MR IMAGING ARTIFACTS: They are defined as either any signal or void in the images that does not have an…

or with the appearance of a swollen or bony bump at the base of the head . Johansson Larsen syndrome is very similar to Osgood-Schlatter disease, but in this case the injury occurs in the tendon (ligament) on the lower patellar pole of the patella . The patella is connected to the tibia by the patellar tendon. When we are in the process of growing, the tendon attaches to a growth plate (or epiphyseal plate) located at the base of the kneecap. Repeated stress on the patellar tendon as a result…

There are many different parts to the knee, 2 bones, tibia and femur, 2 groups of muscles, quadriceps, which straightens the leg and the hamstrings which flex the knee. The knee cap, or the patella, which is the largest sesamoid bone in the body, synovial membranes, joints, cartilage, tendons, 4 ligaments, the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial cruciate ligament (MCL) and the lateral cruciate ligament (LCL). There are also sac like pouches called menisci…
