Knee arthritis

The commonest joint we replace, and the one where non-surgical treatment achieves most.

What you may notice

Knee arthritis

Very common from the sixties onwards, and after ligament or meniscal injury

Knee osteoarthritis often affects one compartment more than the others, which matters because a partial replacement is possible where the rest of the joint is sound. Before any of that, a structured strengthening programme, weight management where relevant and injection therapy relieve symptoms for a great many people. Surgery is a good operation done at the right time and a poor one done early.

What people notice

  • Pain on stairs and after prolonged sitting
  • Swelling after activity
  • Grinding or catching within the joint
  • A knee that has become bowed or knock-kneed

This is general information, not a diagnosis. If any of it sounds like you, ask to be assessed.

Usually managed with

  • Consultant assessment
  • Knee replacement
  • Injection therapy
  • Rehabilitation

Consultations are with a consultant orthopaedic surgeon. Bring any imaging you have already had — it often saves repeating it.
