Like in some people, the osteoarthritis in your shoulder may follow an expected pattern. This includes:
Your cartilage starts to soften.
Irregularities start to develop in the surface of your cartilage.
The surface of your cartilage starts to flake and wear off.
Your cartilage wears off completely, exposing the bone underneath.
This process can happen at different paces. But the more you use your shoulder joint, the faster your cartilage is likely to wear away.
