When to Tell an Adult

Choose a depth

For Young Learners

Function

Who counts as an adult here depends on where you are. A parent or carer. A teacher. Your coach. A doctor or a physiotherapist. Any of them can help you work out whether this needs a professional.

What to say is simple, and being specific helps more than being brave. When it started. What you were doing. Where exactly it hurts. Whether it swelled, and how quickly. What it stops you doing now.

One thing worth being clear about. Nobody on this site can tell you what is wrong with your knee, and neither can the internet. This page helps you decide whether to ask. The asking is the part that matters.

Clinical Relevance

Young athletes are often reluctant to say anything. You do not want to be dropped, you do not want to seem soft, and you assume it will settle. Most of the time it does. Sometimes it does not, and the cost of staying quiet is a longer time out rather than a shorter one.

Tell someone the same day if any of these happen.

You cannot put weight on the leg after an injury. Not limping, actually cannot.

The knee swelled up within a few hours of an injury. Fast swelling usually means bleeding inside the joint.

You heard or felt a pop at the moment of injury, and the knee felt wrong afterwards.

The knee is stuck and will not straighten, however hard you try.

The knee is hot, red and swollen and you feel unwell or feverish. This one needs seeing the same day, not tomorrow.

Your foot or lower leg feels numb, cold, or has gone a strange colour after a knee injury.

Tell someone within a few days if the knee gives way when you are walking or turning, if pain is stopping you training or sleeping, if it keeps swelling up after activity, or if something has been sore for more than two or three weeks and is not improving.

Key Learning Points

  • Cannot bear weight, rapid swelling, a pop, or a locked knee all mean tell someone today.
  • A hot red swollen knee with feeling unwell needs seeing the same day.
  • Numbness, coldness or colour change in the foot after a knee injury is urgent.
  • Giving way, disturbed sleep, or soreness lasting weeks means tell someone soon.
  • Say when it started, what you were doing, where it hurts and how fast it swelled.

If any of this sounds like something happening to you, speak to a parent, teacher, coach or doctor.

References

No reference list is attached to this draft. Evidence verification has not run, because source retrieval was unavailable at generation time. Under the Operations Handbook a missing reference is acceptable and an invented one is a critical failure, so nothing has been cited. The medical student tier is written to descriptive anatomy and physiology only, carrying no statistic, incidence figure, indication, outcome claim or guideline statement, so no in text citation marker is required at this stage. Every claim is listed for verification in the accompanying handoff block.

Safety. KneeSchool is educational and does not give individual medical advice. Seek urgent assessment for a knee that cannot bear weight after an injury, a hot swollen knee with a fever, or new numbness, weakness or coldness in the leg or foot.
