Injuries to the upper leg are some of the most common musculoskeletal injuries seen in sports of all types. The anterior or front portion of the upper leg is made up of four muscles known as the quadriceps .The back portion is made up of a group of three muscles known as the hamstring muscles. These muscles along with multiple tendons and ligaments surround the femur which is the only bone that makes up the upper leg. Most sports related injuries are a result of injuries to the soft tissues in the upper leg and are often a result of improper flexibility training or strength imbalances in portions of the leg. It is important to get on the proper treatment plan to help rehabilitate the upper leg injury. If it is a soft tissue injury, then you can treat the initial stages of the injury by following the R.I.C.E. treatment method.
