Osteolysis refers to an active resorption or dissolution of bone tissue as part of an ongoing disease process.

While bone resorption is commonly associated with many diseases, the term osteolysis generally refers to a problem common to artificial joint replacements such as total hip replacements, total knee replacements and total shoulder replacements.

In total hip replacement, the particles worn off the gliding surface of the ball and socket joint often cause osteolysis. As the body attempts to clean up these loose particles of plastic or metal, the bone grows away from the implant, causing it to loosen. This may require a revision surgery (replacement parts).
