Thigh contusions are common injuries in sports, and the thigh is a very common location for sports-related muscle contusions. Treatment starts with placement of the knee in 120 of flexion for 24 hours. Nonsteroidal anti-inflammatory drugs can be detrimental to the healing if used for more than 48 to 72 hours, and glucocorticosteroids should be avoided. Early treatment with knee flexion to 120 degrees is very important, and is followed by range-of-motion exercises and advancement of activity. Early proper treatment is the key to success. Complications of myositis ossificans and compartment syndrome need to be considered.
