Knee pain is one of the most common reasons people see a GP or a musculoskeletal practitioner, affecting everyone from teenage athletes to older adults. Some problems come on gradually with load, such as runner's knee or osteoarthritis, while others follow a twist or a fall. Most knee pain improves with the right advice, a well-planned exercise programme and sensible changes to activity.
