Bone+Replacement

=BONE REPLACEMENT=

Sometimes people have bone replacments if there bone is damaged or not functioning. You can get knee replacements if your knee hurts when moved and is always stiff. Knee replacements are done by either numbing you or putting you to sleep. Then they add a metal or plastic joint after taking the old one out. Finally they give you a cement or another material knee cap and stitch up the skin. People might have to get hip replacements if they have destroyed cartilage, narrowed joint space, and bone spurs. When you get a replacement done they take out the ball part of the ball and socket joint. The people giving you the surgery replace the damaged femoral bone (ball of ball and socket joint) with a metal or ceramic one. Then the surgeons have to replace the damage cartilage socket (acetabulum) with a metal socket
