Secondly, physical therapy can help you strengthen the quadriceps and hamstring muscles. This increased strength is a key factor to help prevent the knee from giving out if a sudden spike of pain occurs. Therapy will also increase the endurance of these muscles. A couple of weeks of supervised physical therapy will improve your understanding of how to perform the exercises. An important component of this is to learn a good home program that will help to maintain and improve upon the supervised physical therapy.

Generally, non-impact exercises are recommended. This includes the use of a stationary bicycle, elliptical machine, or pool exercises. Make sure to visit the home exercisehome exercise module to learn relatively simple exercises that can be done while lying, sitting and standing.
