MSD stands for Musculoskeletal Disorder, which affects the muscles, nerves, blood vessels, ligaments, and tendons. Exposure to these known risk factors for MSDs increases a worker's risk of injury.
According to the Academy of Orthopedic Surgeons, patellofemoral pain syndrome (PFPS) is a broad term used to describe pain in the front of the knee and around the patella, or kneecap. It is sometimes called "runner's knee" or "jumper's knee" because it is common in people who participate in sports—particularly females and young adults—but PFPS can occur in nonathletes, as well. The pain and stiffness caused by PFPS can make it difficult to climb stairs, kneel down, and perform other everyday activities.
