the posterior cruciate ligament(PCL). The PCL is in the middle of the knee and works with the ACL to prevent the tibia(shin bone) from sliding underneath the femur(thighbone). Finally, the last is the ACL. ACL stands for Anterior Cruciate Ligament. The ACL is in the middle of the knee and it stops the tibia from sliding out in front of the femur. Some studies have shown that women are 2 to 10 time more likely to tear their ACL than a man is. While there is no single answer, doctors believe…

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…

The knee is a very complex structure and an essential joint that needs to be fully functioning for all athletes. It is one of the most complicated structures and the largest joint in our body (Marieb & Hoehn, 2013). The ligaments are what keep the knee in place and allow us to move and be mobile. This structure is also the most vulnerable because it is the part of our body that bears the most weight and pressure and needs to be flexible in order to maintain its purpose. We need our knees to…

This movement requires the use of the knees, which includes tibiofemoral joint and the femoropatellar joint. The tibiofemoral joint is a type of synovial joint called a hinge joint, which is located where femur and tibia articulate, allowing only movement in one plane, but can perform flexion, extension, slight rotation when it is flexed, and diarthrotic. However, the tibiofemoral joint is used during backwards marching to implement extension, the straightening…

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…

Secondly, the length of residual femur affects hip muscle strength too. The force can be generated by a muscle is affected by the muscle force magnitude and the distance from the muscle attachment to the axis of rotation (Rassier et al., 1999). For example, the force can be generated by gluteus maximus is reduced if femur residue length is shorter. Therefore, amputees need to recruit more motor units in order to generate adequate force in walking. This can rationalise energy expenditure on…

in the body. The knee is located at the juncture of three bones, the femur, the tibia and the patella. The femur (the upper leg bone) and the tibia (the shinbone) are connected by the anterior and posterior cruciate ligaments. The joint is cushioned by the meniscus, a tough cartilage material, during movement. The patella (or kneecap) is a small bone, encased in tendons, that glides up and down in the groove on the top of the femur when the knee is flexed and extended. Knee can not only bend and…

tear of his right acetabular labrum when the head of his femur pinched the labrum against his os coxa. The pinch resulted from a swift anterior force from an opponent’s screen during a basketball game. Our athlete has been playing basketball since age 5 and has been experiencing signs and symptoms of FAI for the last 5 years. Team physicians feel that the FAI is largely a consequence of the repeated compressive forces experienced by the femur when the hip is either flexed, extended, abducted…

Ideokinesis, a practice that provides physical benefits in terms of fluidity in movement, posture, and body alignment through the process of imagery and visualization, utilizes multiple techniques in order to train specific body systems such as the skeletal and nervous systems to adapt to newer and healthier neuromuscular methods. A significant mechanism used to teach the benefits of Ideokinesis is the 9 lines of movement. Reflecting on and working towards stabilizing the 9 lines of movement…
