Knee injuries

The principles that govern the NMR experiments described throughout this textbook have begun to find application in the field of medicine. A very important diagnostic tool in medicine is a technique known as magnetic resonance imaging (MRI). In the space of only a few years, MRI has found wide use in the diagnosis of injuries and other forms of abnormality. It is quite common for sports fans to hear of a football star who has sustained a knee injury and had it examined via an MRI scan. 

Sport and physical activity have become increasingly popular, but this trend is accompanied by an increased risk of muscle and muscoskeletal injuries. Strenuous exercise can result in muscle injury that may persist for 2 weeks. P MRS can detect evidence of muscle injury completely noninvasively. One hour after exercise, a significant increase in the inorganic phosphate to phosphocreatine ratio was observed Pi/PCr remained elevated for 3-10 days [100]. The studies of acute knee injury on a large population of patients (840) showed that MRI increased clinical diagnostic certainty and reduced the need for arthroscopy [101].

Based on the above process, after these healthy subjects without the knee pain or knee injury were administrated individually two antioxidant vitamins of ascorbic acid (49) and vitamin E (50), and the food somces including 6 antioxidant carotenoids such as a-carotene (1), P-carotene (2), P-cryptoxanthin (5), lutein (6), zeaxanthin (9) and lycopene (3). 

Q. An employee who performs office clerical work injures her knee in a work-related accident. She has out-patient surgery one month after the knee injury and is released hy her doctor with the only restriction being May work at home. The company sets up a computer and forwards her business phone to the employee s house so she can work while recovering from surgery.
