The 4 Stages of Knee Arthritis: Which Stage Are You In?

Knee arthritis gets worse over time. Learn about the 4 stages of osteoarthritis, from early symptoms to severe joint damage, and the best treatments for each stage.

The 4 Stages of Knee Arthritis: Which Stage Are You In?

Osteoarthritis (OA) is a progressive disease. It doesn't happen overnight. It develops in four distinct stages, and the treatment depends entirely on how advanced your condition is.

Here is a breakdown of the stages of knee arthritis to help you understand your condition.


Stage 1: Minor (Doubtful)

What’s happening:

  • Very minor wear on the cartilage.
  • Tiny bone spurs (osteophytes) may begin to grow.

Symptoms:

  • Usually no pain.
  • You might feel slight stiffness occasionally.

Treatment:

  • Supplements (Glucosamine/Chondroitin) may help (consult your doctor).
  • Regular exercise to keep joints healthy.

Stage 2: Mild (Minimal)

What’s happening:

  • Bone spurs are visible on X-rays.
  • Cartilage is starting to thin, but the bones are not rubbing yet.
  • Synovial fluid is still present.

Symptoms:

  • Pain after a long walk or run.
  • Stiffness when waking up or after sitting for a long time.
  • Tenderness when kneeling.

Treatment:

  • Weight loss if overweight.
  • Low-impact exercise (swimming, cycling).
  • Shoe inserts or braces.
  • Pain relief medication (NSAIDs) when needed.

Stage 3: Moderate (Significant)

What’s happening:

  • The cartilage is showing clear gaps and cracks.
  • The gap between bones is narrowing.
  • Bone spurs are larger.

Symptoms:

  • Frequent pain with movement (walking, stairs, bending).
  • Morning stiffness lasts longer.
  • Swelling (water on the knee) may occur after activity.
  • Popping or clicking sounds (crepitus).

Treatment:

  • Physiotherapy is crucial.
  • Injections: Corticosteroids or Viscosupplementation (Gel injections) to lubricate the joint.
  • Pain management is a daily routine.

Stage 4: Severe (Advanced)

What’s happening:

  • Bone-on-bone: The cartilage is almost completely gone.
  • The joint space is drastically reduced.
  • The bone ends are rubbing against each other.

Symptoms:

  • Constant, severe pain (even at rest or at night).
  • Walking is very difficult and painful.
  • The knee may look deformed (knock-kneed or bow-legged).
  • Stiffness is severe.

Treatment:

  • At this stage, conservative treatments usually stop working.
  • Total Knee Replacement Surgery is often the only option to restore quality of life.

Takeaway

Arthritis cannot be cured, but it can be managed.

  • In Stages 1 & 2, lifestyle changes are key.
  • In Stage 3, injections and therapy help.
  • In Stage 4, surgery provides a new lease on life.

Don't wait until Stage 4 to seek help. Early intervention is best. 👉 Book an assessment with Dr. Abhijit Kale.
