CONSERVATIVE CONSERVATIVE MANAGEMENTMANAGEMENT Mild knee injury should be treated with R.I.C.E. (rest, ice, compression, elevation), and paracetamol (Caillient)
Avoid H.A.R.M. (heat, alcohol, running, massage) in first 72 hours.
Resume activities gradually as pain and swelling settle, with follow-up after 7 days if symptoms persist.
