The knee is considered a hinge joint while the hip is a ball-and-socket joint. They are both complex joints with a network of muscles, tendons, ligaments, bone, and cartilage all working together to keep you moving. With this many moving parts it’s not surprising that as we age or engage in strenuous activity that we sometimes experience pain. When you’re suffering from hip or knee pain it can make doing even the most basic daily activities difficult. Understanding the causes of hip and knee problems is often the key to effectively treating them. If you’re struggling with hip or knee pain a physical therapist can help you reduce or even eliminate the amount of pain you’re experiencing.
