Knee joint is the largest and most complicated joint in the human body.
It is a remarkable joint by engineering standards; there is no engineering bearing that resembles it either in construction or in the complexity of its geometry [1]. The knee has very effectively evolved to move from 0o extension to 135o flexion together with 20o to 30o rotation of the flexed leg on the femoral condyles. The knee is used for everything from standing up, sitting, walking, running, etc. It’s a weight-bearing joint that straightens bends, twist and rotates. All this motion increases risk of acute or overuse knee injuries. Acute knee injuries including torn ligaments and torn cartilage are often caused by twisting the knee or falling. Sports that involve running

Overuse knee injuries including muscle strain, tendonitis and bursitis may develop gradually over days or weeks. Pain is often mild and intermittent in the beginning and worsens over time. When muscles and tendons are stressed even slightly beyond their capabilities, microscopic tears occur. These tears must be given a chance to heal before subjected to the same activity to avoid overuse injury. Treat overuse injuries early to prevent chronic problems. Knee osteoarthritis is a common cause of knee pain. The risk increases with age. Osteoarthritis is a form of arthritis involving degeneration of the cartilage [3,4]. By determining the medical history of a patient and comparing it to the patient's current symptoms a medical professional can determine the source of the knee pain. Additional tests, such as X-ray, CT scan, MRI, Bone scan, Ultrasound and Arthroscopy make the diagnosis clear to both the patient and the doctor [5].
The non-invasive imaging techniques of X-ray, CT-scan, MRI, Bone scan and Ultrasound can capture only gross cartilage defects and may not be useful for early detection of cartilage pathology [6]. The semi-invasive

Task 8.1b- disorders and dysfunctions of the musculoskeletal system Osteoarthritis Osteoarthritis is the most common arthritis. It is an incurable condition which affects your joints. The surface within the joints become joints become damaged which stops the joints moving smoothly. [1] The symptoms of this are: o Pain and stiffness o Swelling o Not being able to move the joint normally o A grating/grinding feeling
The ACL crosses diagonally in the middle of the knee behind the patella and it connects the tibia to the femur. Its function is to prevent the tibia from sliding in front of the femur and to prevent overextension of the knee. The LCL connects the femur to the fibula and its function is to keep the lateral side of the knee stable. RG3’s injury is due to an ACL and LCL tear. The ACL was torn when his foot planted in the field and his knee cut into internal rotation.
This is causing children to use the same muscles constantly. ACL tears have dramatically increased in the last 12 years. there has been a 400% jump in knee injuries since 1999(Knee Injuries on the Rise in Young
Review # 259374 Lucila Fernandez DOI: 03/28/2016. This is a 52-year-old female housekeeper who sustained an injury when she lost footing and twisted her right knee before completely falling 2 flights of stairs. The patient was subsequently diagnosed with meniscal tear. MRI of right knee without gadolinium dated 4/23/16 revealed there is a high-grade sprain of the ACL; there is a low-grade sprain of the MCL; there is a vertical oblique tear through the body of the medial meniscus with underlying chondromalacic change and subchondral edema; and mild to moderate chondromalacia of the patella.
Compress your knee with an elastic bandage and elevate on while laying down, the injured knee should be above the heart. Anti-inflammatory medication is also effective when trying to reduce pain. If you are not having instability in your knee then most of the average people let it heal on it 's own because they wouldn 't have to take to risk of surgery (Cluett 25). Surgery is a risk, many athletes are concerned about the small risk of transmission of infections. Diseases like AIDS can be transferred because of the true graft operation where an ACL is taken from a dead human and used as the ligament of someone else.
Osgood-Schlatter Disease Osgood-Schlatter disease is an inflammation of the area below your kneecap called the tibial tubercle. There is pain and tenderness in this area because of the inflammation. It is most often seen in children and adolescents during the time of growth spurts. The muscles and cord-like structures that attach muscle to bone (tendons) tighten as the bones are becoming longer. This puts more strain on areas of tendon attachment.
Introduction The aim of this review paper is to access the anterior cruciate ligament (ACL) injury of the knee (tibiofemoral) joint, which is a common sport and exercise injury related to the musculoskeletal system. Investigation of the anatomy and physiology of the knee joint, and the diagnosis, etiology, pathophysiology, treatment, rehabilitation and prevention of ACL injuries will provide a descriptive epidemiology. This will aid readers in making informed management and treatment decisions, and guide them to safely perform movements to prevent injury. This review paper will incorporate holistic views on relevant scientific research, including primary resources such as journal articles and lecture notes, which will be cross-referenced
These injuries are from being hit or pushed directly to either side of the knee which will cause a sprain to which ever side has been hit. There
ACL tears can affect lots of people but with surgery you can come back from an injury better than before. ACL tears are a serious injury because they do not heal themselves so no matter what they will require surgery or rehab to make the knee more stable. Usually it tear by doing athletic stuff such as sports. When the ACL tears people will usually feel a pop of the muscle tearing. Tackling can tear your ACL if you get hit on the side of the knee.
The knee joint is one of the strongest and most important joints in the human body. It allows the lower leg to move relative to the thigh while supporting the body’s weight (Taylor, n.d.) as knee joint is one of the major weights bearing joint in the body. Knee joint plays an important role in our daily lives such as walking, running, sitting and standing. It allows physiological movement such as flexion and extension.
The most common knee injuries and torn ligaments are in football. Some of these injuries could end your college season of football, and you would not even get paid once you have to stop because of an
These knee injuries can affect a player's long term involvement in the sport. Football players also have a much higher chance of ankle sprains due to the surfaces of the fields they play on and cutting motions. Shoulder injuries are also common and the labrum (cartilage bumper surrounding the socket part of the shoulder) is particularly susceptible to injury, especially in offensive and defensive linemen. In addition, injuries to the acromioclavicular joint (ACJ) or shoulder are seen in football players. Football players are very susceptible to receiving concussions.
Some symptoms of patellar tendonitis can vary depending on the condition, but usually pain in the kneecap, worsens when pressure is used, and interference in physical activities. First and most common sign of jumper’s knee is pain right below the kneecap where the patellar tendon is located. This pain can affect walking and other physical activities, when this pain occurs the best thing to do is to go see a doctor and if in any sport tell your coach that you cannot practice. Swellness will also occur on the knee and by the knee.icing the knee is also a good idea to reduce swellness(houston, symptoms
Abstract— The main aim is to develop the three dimensional solid finite element model of knee joint to predict stress in its individual components (Femur, Tibia, Menisci and Patella) and to determine the load carried by a pre – selected ligamentous tissue. This work assists to analyze a knee response to a dynamically applied load. This simulated analysis will serve to be an alternative approach to destructive tests and intrusive procedures and helps to achieve closer simulation to reality. The main expectation is to simulate the whole articulation using three dimensional solid models. This paper will aid to control the geometry of movements of knee joint.
This tendon does get overworked and in time, with constant pressure small tears begin to appear. These get progressively worse and the pain increases as the tears become inflamed as you put the foot on a repetitive stretching and tearing process when
