Osteoarthritis is a degenerative joint disease that affects the cartilage in joints. Knee osteoarthritis is a common condition, and its severity can vary. Here are the stages:
Stage 0: Normal
- No signs of osteoarthritis.
- The knee joint is healthy.
Stage 1: Mild
- Early signs of wear and tear.
- You may not experience any symptoms.
- X-rays might show minor changes in the cartilage.
Stage 2: Moderate
- Moderate cartilage loss.
- You may experience pain, stiffness, and swelling.
- The joint space may be narrowing.
Stage 3: Severe
- Significant cartilage loss.
- Pain and stiffness are likely to be more severe.
- Bone spurs may form.
- Joint function may be limited.
Stage 4: End-stage
- Complete cartilage loss.
- Severe pain and limited mobility.
- Bones may be rubbing against each other.
- Surgery, such as a knee replacement, may be necessary.
Note: These stages are based on X-ray findings. However, it is important to remember that symptoms can vary from person to person, even at the same stage.
