Knee

The knee joint is one of many synovial joints within the human body. It is the largest joint in the body and is known as a ginglymus, or hinge, joint involving the articulation of the femur and the tibia. A hinge joint is a joint between two or more articulating bones, moving in only one plane. The movements that occur at the knee are flexion and extension. The knee joint is a modified hinge joint, therefore as well as allowing the movements of flexion and extension; the movements of internal rotation

9 Symptoms of Arthritis in the Knee Overview Arthritis affects the human joints such as knee joint, hip joint, toe and finger joints among others. I t does not choose the gender or the age hence any one can be affected. This disease is commonly in women as it is stated that they take o a ratio of 6:10 after a certain research by scientists. The following are the symptoms of arthritis in the knee 1. Swelling/tenderness Most common type of arthritis is osteoarthritis but as a patient you need to

most serious and common knee injuries. Many aspects play a role in the treatment and rehabilitation of this injury. This paper will discuss the anatomy of the knee, describe a torn ACL, and the rehabilitation. The knee is a hinge joint which gives the legs mobility. The muscles and ligaments of this joint allows flexion and extension of the leg. “Because the knee supports the majority of the body weight, it is at risk of overuse and traumatic injuries” (France). The knee is composed of 3 major bones;

There are 2 collateral ligaments of the knee; lateral collateral (LCL) and medial collateral (MCL). The LCL attaches from the lateral femoral epicondyle to the lateral part of the fibular head, and is the stronger of the 2 ligaments. It is a thin, round ligament and is extracapsular. The MCL attaches from the medial femoral epicondyle to the medial condyle and superiomedial part of the tibia. It also attaches to the medial meniscus and is a wide, fat ligament (Moore et al. 2010, p. 636). They are

the most common rheumatic disease, primarily affects the articular cartilage and the subchondral bone of a synovial joint, eventually resulting in joint failure. People with progressive symptomatic knee osteoarthritis experience pain and increasing difficulty with daily functional activities. In fact, knee osteoarthritis bears more responsibility than any other disease for disability in walking, stair climbing and housekeeping. Currently, no cure for osteoarthritis is known. However, disease-related

Knee extensor mechanism is a complex structure that comprises of quadriceps muscle and tendon, patella, patellar tendon, and the tibial tubercle (Andrikoula et al. 2006). This mechanism helps extend the knee and stabilizes the knee joint. Rupture of any of the quadriceps or patellar tendon or fracture of the patella can lead to extensor mechanism disruption of the knee (Lynch et al. 1987), (Rosenberg 2012). Total knee arthroplasty (TKA) is considered one of the most common and successful surgical

pivotal hinge joint called knee. The upper and lower extremities are encompassed of tendons, cartilage, ligaments and muscle. Menisci, two concave pads of cartilage, disperse the friction created at the meeting of the ends of the tibia and femur. The key ligaments of the knee are Medial Collateral ligament (MCL), Lateral Collateral ligament (LCL), Anterior cruciate ligament (ACL), Anterolateral ligament (ALL), and Posterior Cruciate ligament (PCL). The knee is comprised of articular

Azevedo et al. (2009) has found that knee range of motion (heel strike to midstance) was significantly lower in injured runners with Achilles tendinopathy than in uninjured runners. In adition, the preactivation (EMG) in 100 ms before heel strike of tibialis anterior was lower for injured runners than uninjured runners. Moreover, rectus femoris and gluteus medius IEMG activity 100 ms after heel strike was also lower in the injured group. In a thesis study from Azevedo and Martin (2008), the author

have said that the best way to reduce injuries is by practicing appropriate postural control. Postural control is also linked with balance. Balance one of the main components of knee injury. Volleyball, basketball, and other active athletes have not developed proper posture to land safely, causing many injuries to the knee and ankles. Point of Agreement I agree that there has to be some reason for non-contact athletes, like volleyball players, are injuring themselves. It makes sense that the injury

Knee pain is intolerable and perhaps the only way to get rid of this pain permanently is by opting for a knee surgery, meniscus knee surgery or arthroscopic knee surgery. About six hundred thousand people all over the world undergo knee surgery every year and about ninety percent of these people feel that their life has become better after the surgery because they can move normally without feeling any pain in their knees. However, this alternative is found to have helped a lot of people all over
