The most common musculoskeletal disorder and a major cause of disability in people over 65 years is osteoarthritis (OA) (Felson DT et al, 1987) (1). According to World Health Organization (WHO) report, OA of knee is more likely to become the fourth most important cause of disability in women, and the eighth most important cause in men (Murray CJL, Lopez AD, 1997)(2) . Primary prevention of knee OA has become a major health care aim and a clear understanding of the risk factors is required to design preventive strategies. Many investigations reported obesity, previous history of knee injury, sedentary life style, hand OA (Heberden’s nodes), and a familial history of the disease are major risk factors for OA of knee (Cyrus Cooper et al, 2000) (3). In spite of recent advancements the causes and pathogenesis of knee OA remains largely unknown (A Teichtahl, A Wluka, F M Cicuttini, 2003) (4) but however there is increasing research interest in the contribution of biomechanical variables on progression and management of the disease (Andriacchi TP, 1991) (5).
The higher the infirmity, the lower the percentage. Global rating of Knee Function scales deliver a technique of attaining statistics in a more quick, flexible, and efficient way. Although, with any conclusion quota important readings of outcomes can only be accepted with the thought of the clinometric assets, powers, and flaws of the tool. Single leg hop tests is a technique that your doctor may practice to define your aptitude to return to exercises, sports and events after knee surgery. It is generally practiced throughout the return to function stage in an anterior cruciate ligament restoration procedure. This is used to evaluate the useful firmness of your knee (Shen. W,
Orthopedic surgeons are responsible for mending and operating on the musculoskeletal system. “Orthopedics is a medical specialty that focuses on the diagnosis, care, and treatment of patients with disorders of the bones, joints, muscles, ligaments, tendons, nerves, and skin” (Career in Orthopaedics). Depending on the damage the patient has sustained determines how the orthopedic surgeon is able to correct the patient’s injury. In many cases there are multiple ways of correcting the patient’s injury such as; using medical, physical, and rehabilitative techniques to using complex surgical methods. “Typically, as much as 50 percent of the orthopedic surgeon’s practice is devoted to no surgical or medical management of injuries or disease and 50 percent to surgical management” (Career in Orthopaedics). The majority of surgeons, including orthopedic surgeons, prefer to choose the least invasive procedures such as; arthroscopy which is a technological advancement allowing orthopedic surgeons to use special cameras in order to diagnose and treat a joint with minimal cutting and trauma to...
An estimated 50 million Americans have suffered or are suffering knee pain or injuries. Most of these pains, sprains, and strains could probably have been avoided with proper conditioning (Fox, 147). I have had knee pain since my freshmen year of high school and have finally taken the initiative to find some exercises that will help ease this pain, and build muscle strength in the surrounding areas to avoid another possible injury.

My name is Lakitta Beverly. I am a junior at Mississippi State University majoring in Kinesiology with a concentration in CLEP (Clinical Exercise Physiology). Throughout high school, I experienced patellar dislocation, which is the topic for today’s Technical Research Report. Patellar dislocation is an injury of the knee. Typically, it is caused by a direct blow or a sudden twist of the leg. It occurs when the patellar slips out of its normal position in the Patellofemoral groove and causes intense pain and swelling of the knee. Patellar dislocation can be characterized as objective patellar instability, potential patellar instability, and episodic patellar instability. (Cerciello, 1) Episodic patellar instability is one of the major categories
The most common knee injury in sports is damage to the anterior cruciate ligament (ACL) through tears or sprains. “They occur in high demand sports that involve planting and cutting, jumping with a poor landing, and stopping immediately or changing directions” (University of Colorado Hospital). The ACL is a ligament that runs diagonally in the middle of the knee and found at the front of the patellar bone. Its function involves controlling the back and forth motion of the knee, preventing the tibia from sliding out in front of the femur, and providing rational stability to the knee. Interestingly, women are more prone to ACL injuries than men. The occurrence is four to six times greater in female athletes.
The direction of the knee joint movement is regularly controlled by the ligaments and geometric constraints of the articular surfaces (Woo et al., 1999). The movements of the knee can occur in different directions which gives each ligament a multifunctional purpose. The major function of the anterior cruciate ligament is to prevent extreme anterior tibial movement in different degrees of flexion. The ligament itself aids significantly to the stabilization and the kinematics of the knee joint.In addition, the ACL functions as a major secondary restraint to internal rotation, particularly when the knee is near full extension.(Duthon et al., 2006)
The word patella comes from the great latin language meaning shallow pan or shallow dish. The description of that word could not be more correct, it was meant in reference to balance of food but in anatomy’s case a balance of the body. The patella is a small bone located in front of the knee joint where the thigh bone (femur) and shinbone (tibia) meet. It protects the knee and connects the muscles in the front of the thigh to the tibia. The patella is one of two sesamoid bones found in the body, roughly triangular shaped in size. It’s thick consistency allows for the articulation of the femur, which in turn allows for body support and balance. The patella has multiple body functions with the primary being knee extension. The patella is essential for basic body functions including locomotion;
The purpose of the squat is to train the muscles around the knees and hip joints, as well as to develop strength in the lower back, for execution of basic skills required in many sporting events and activities of daily living. Because a strong and stable knee is extremely important to an athlete or patient’s success, an understanding of knee biomechanics while performing the squat is helpful to therapists, trainers, and athletes alike (11). Because most activities of daily living require the coordinated contraction of several muscle groups at once, and squatting (a multi-joint movement) is one of the few strength training exercises that is able to effectively recruit multiple muscle groups in a single movement, squats are considered one of the most functional and efficient weight-bearing exercises whether an individual’s goals are sport specific or are for an increased quality of life
