In simple words

Knee pain is discomfort in or around the knee joint. It can start after an injury, develop gradually, or come and go with activity.

Clinical Meaning

Common causes include a strain, overuse, arthritis, tendon irritation, or a kneecap problem. The way symptoms began, the ability to bear weight, swelling, warmth, and locking or giving way help guide the next step.

Common Causes

  • A twist, fall, overuse, or a sprain or strain
  • Tendon irritation from running, jumping, kneeling, or repetitive activity
  • Osteoarthritis or another long-term joint condition
  • Less commonly, gout, bursitis, infection, or a ligament, cartilage, or kneecap injury

Clinical Red Flags

Seek urgent medical attention at an emergency department or primary care clinic if you present with any of the following symptoms:

  • Get urgent help if you cannot move the knee or bear weight, it is badly swollen or changed shape, or it locks or repeatedly gives way
  • Seek urgent assessment for a hot, red, very painful knee with fever, chills, or feeling unwell
  • Book a review if pain is worsening, affects normal activities, follows a significant injury, or is not improving after a few weeks

Lifestyle & Diet Support

Reduce activities that clearly worsen pain at first, use an ice pack wrapped in a cloth for up to 20 minutes at a time, and keep gently moving within comfort. Avoid long periods of complete rest. A pharmacist can advise whether pain medicine is suitable for you.

Frequently Asked Questions

For most mild strains, gentle movement helps prevent stiffness. Avoid activities that sharply increase pain and seek urgent advice if you cannot bear weight or the knee is unstable.
Seek urgent assessment if the knee is deformed, very swollen, hot and red, you cannot move it or put weight through it, or you feel unwell with fever.
No. Painless clicking can be normal. Painful clicking, locking, giving way, or a sudden injury should be assessed.

Differential Diagnosis Matrix

Differential Diagnosis Overview

A clinician may assess the injury mechanism, movement, stability, swelling, warmth, and whether the knee locks, clicks painfully, or gives way. A hot red joint with fever is different from a mild strain and needs urgent assessment.
