What Are the Stages of Knee OA?

You want the stages of knee osteoarthritis laid out, and a stage number on a chart can look more settled than it is.

What can be documented about stages

OrthoInfo (AAOS) uses the term early-stage when it describes a procedure.

Knee osteotomy is used when you have early-stage osteoarthritis that has damaged just one side of the knee joint.

Where stage labels go past the evidence

That sentence places early-stage osteoarthritis in the case where damage is limited to one side of the joint. Middle or late stages are not defined there, so ask what a clinician means by any stage you are given. A chart that gives every stage a symptom list and a timeline needs a named publisher and a named grading system before it earns trust. Ask any chart's author which ones they used.

What to ask next

Ask the clinician reviewing your knee which grading system they use and where your knee falls in it. A clinician in Totowa can answer that once they have examined the joint. Read MedlinePlus's page on knee injuries and disorders, WebMD's pain management center and OrthoInfo's guide to arthritis of the knee with that answer in hand.

A diagnostician's note

A stage is a label, and a label is only as good as the standard behind it. You can verify any stage claim alone by asking for the standard by name and finding it published.
