1. The 4 Stages of Knee Osteoarthritis
Why standing X-rays are essential and how treatment matches your exact stage| Arthritis Stage | What Happens Inside the Joint | Common Symptoms | Recommended Treatment |
|---|---|---|---|
| Stage 1 (Early / Doubtful) | Minor cartilage softening; normal joint space on X-ray. | Occasional ache after long walks or climbing many stairs. | Quadriceps exercises, weight control, Vitamin D3/Calcium optimization. |
| Stage 2 (Mild) | Early bone spurs (osteophytes); cartilage cushion slightly thinned. | Morning stiffness (<30 mins), pain when squatting or sitting cross-legged. | Physiotherapy, avoiding floor sitting, cushioned footwear, short-course chondroprotective supplements. |
| Stage 3 (Moderate) | Visible narrowing of joint space; rough cartilage surfaces. | Pain during daily walking, creaking sound (crepitus), mild swelling. | Targeted physiotherapy, knee offloading brace/insole, intra-articular gel (viscosupplementation) injection, or realignment. |
| Stage 4 (Severe / Bone-on-Bone) | Cartilage completely worn away; raw bone rubs on bone with bow-leg deformity. | Constant pain even at rest/night, bowed legs, walking restricted to a few minutes. | Total Knee Replacement (TKR) or Partial Knee Replacement for lasting pain-free mobility. |
