Knee and lower extremity pain can result from soft tissue injuries (muscle, ligament, meniscus), bone conditions (arthritis), and biomechanical dysfunction (patellofemoral). These injuries can be a result of sport, work or everyday use. Knee and lower extremity pain can also be referred from an issue at another location of the body (lumbar spine, hip). Accurate diagnosis by a physiotherapist will assure proper management and most optimal outcome following an injury.
