Knee care

Start with what your knee is stopping you doing

Knee problems can change ordinary days: getting down stairs, standing at work, joining a walk or getting up from a chair. Pain is useful information, but it does not identify the cause by itself. The aim of an assessment is to understand the problem and its effect on your life before choosing treatment. This page helps you navigate the knee resources and prepare for that conversation.

Think of one or two activities you most want to regain. A patient who cannot comfortably walk to the shops may have different priorities from someone whose knee gives way during football. Tell the clinician what matters to you, including activities you have quietly stopped doing. You do not need a technical diagnosis to ask for help.

Different symptoms can need different explanations

The knee contains joint surfaces, menisci, ligaments and tendons. Injuries may affect more than one structure. Swelling, difficulty straightening and a feeling of instability can accompany injury, but an examination is needed to understand why. A twisting incident and gradually increasing stiffness are different starting points for assessment, even when both are described as knee pain.

Our knee osteoarthritis guide explains a common cause of persistent pain and stiffness. The ACL guide explores instability after ligament injury, while the meniscus guide discusses a different structure within the joint. These articles are educational starting points. Do not choose a diagnosis simply because one description sounds familiar or a scan report contains the same word.

What to bring to an assessment

Write down when the problem began, whether there was an injury, where it hurts and what makes daily tasks difficult. Mention swelling, locking, giving way and previous treatment. Bring existing images and reports if available, along with medication and allergy information. Do not arrange an MRI just to have something to bring: the need for imaging depends on the clinical assessment.

It can help to prepare a short timeline rather than a long list of possible diagnoses. For example, note the activity at the start, whether you could continue, and how symptoms changed afterward. Keep the description factual. If you are unsure about a detail, say so; a precise answer is not required for every question.

Treatment is a discussion, not an automatic operation

Depending on the cause, care may include a change in activity, rehabilitation, support or appropriate pain management. Some injuries require surgery, while others can be managed without it. The same treatment is not suitable for every painful knee. Ask what a proposed option aims to improve, what its limits are and how progress will be assessed.

If replacement is being considered for arthritis, use the knee replacement guide to explore the decision in more depth. An educational page cannot establish your eligibility. Take questions about benefits, risks, alternatives and recovery to the treating surgeon. Ask what should happen if the first approach does not meet the agreed goals.

Know when not to wait

Seek prompt medical assessment for severe pain, major swelling, a knee that cannot move or bear weight, or a changed shape after injury. A hot, red knee with fever or feeling unwell needs urgent assessment. For a severe injury or emergency, go to an emergency department rather than waiting for a routine appointment or a WhatsApp reply.

Choose your next step

For persistent symptoms without emergency features, arrange a consultation and bring your questions. Use the related guides to understand unfamiliar terms before the visit, then confirm which information applies to you. Ask for a clear follow-up plan, including who to contact if symptoms change. Recovery goals and timing should be agreed around the diagnosis and your circumstances, rather than borrowed from another person’s experience.
