A member asked:
Is it possible to grow bone back to avoid having a knee or hip replacement?
9 doctors weighed in across 3 answers
No: Bone is not the problem, arthritis is caused by a loss of cartilage covering the bone. Cartilage is that smooth shiny stuff on the end of the bone like you see on a drumstick at the joint. We have many procedures to reproduce it in small amounts or repair it if only small areas are lost or damaged, but when there is more exposed bone than cartilage, hip or knee replacement becomes necessary.

No: The problem is worn out cartilage. The bone only becomes worn out later in the disease. Neither can be replaced well with natural tissue right now.

Cartilage transplant: It is possible to replace the meniscus cartilage and perform a stem cell paste graft for many patients who have been told they need a knee replacement. This is called a biologic knee replacement.
