I hurt my knee at work, after seeing an orthopedic he put me in a brace and physical therapy in a few weeks... is it possible that my hip, calf muscle, and akle hurt now due to my knee injury?

Knee Injury. Absolutely! The lower extremity acts as a unit. A movement group called a kinetic chain. Muscles and tendons go from buttock and hip to knee. Muscles and tendons around knee influence the ankle. Without knowing the full extent of the injury can only remark that it is not unusual to hurt above and below the main area of injury. .
