Pain around the kneecap

As the knee bends and straightens, the kneecap moves along a groove in the thigh bone. Activity-related pain in this area is often called patellofemoral pain syndrome. It may occur when climbing stairs, standing up, squatting or after prolonged sitting, and can also affect people who do not take part in sport. However, not all pain at the front of the knee is part of this pain syndrome. Osteoarthritis behind the kneecap, tendon symptoms or instability may require a different assessment. The cause should be reassessed particularly after an injury or with marked swelling. A grating sound alone cannot establish either a particular form of cartilage damage or its severity.

Sometimes symptoms start after a rapid increase in training. They can also arise when more stairs, walking or physical work are added after a longer quiet period. Often, more than one factor is involved. The question is therefore not only which movement hurts, but also how often and how intensely it is now required. The knee usually needs an appropriate gradual progression rather than switching between complete rest and overly large increases in activity. To begin with, it may help to break up particularly aggravating tasks and maintain movement you can tolerate. The adjustment that suits you can be identified from your daily life and the examination.

We want to know where the pain is, how it began and whether the knee swells, locks or actually becomes unstable. The examination may consider mobility, strength, kneecap tracking, and the hip and foot. A selected movement helps establish whether the familiar pain is reproduced. Not every case of pain at the front of the knee needs an immediate MRI. Imaging is used when it can answer an additional question, for example after an injury, for persistent unexplained symptoms or if a joint change is suspected. Findings are always considered alongside the examination and the limitations you experience.

Targeted exercise therapy and a clear explanation of the condition are central to managing patellofemoral pain syndrome. Rehabilitation may combine exercises for the knee and hip muscles. The amount, range of movement and progression should be chosen to suit your current capacity for activity. One set exercise is not equally suitable for everyone. You should understand what an exercise is intended to improve and how to respond to an unfavourable reaction. Agree with your treating clinician which symptoms are tolerable as you progress and which changes should prompt you to ask for advice. A general motto such as ‘push through the pain’ does not replace this plan.

Taping or suitable insoles can be tried as additional measures for selected findings. What matters is whether they make helpful movement easier and fit the plan. They do not replace active rehabilitation. Painkillers are also used only after weighing up benefits, risks and your other medication. If an appropriate additional joint or cartilage finding is identified, hyaluronic acid or PRP may also be considered. We discuss whether such an injection is appropriate based on the specific diagnosis and its possible benefits and risks. It is not part of the usual treatment for patellofemoral pain syndrome without a corresponding additional finding. Surgery is not a usual first-line treatment for patellofemoral pain syndrome alone. If the examination identifies another cause, such as repeated dislocations or a relevant joint change, this is assessed separately. Treatment is guided by the established cause, not just the location of pain.

Before the appointment, think about which situation you would like to improve first: using stairs in daily life, getting up after a car journey or returning to a sport. Note how your knee responds during and after activity. These observations help us adjust your progression in a targeted way. Bring existing reports and information about previous exercises or aids. If your knee suddenly becomes hot and very swollen, fever develops or you can no longer bear weight after an injury, urgent medical assessment is required.
