Surgeons began using ceramics for hip replacement surgery due to the problems of friction and wear often reported with metal or metal and plastic.
Artificial hips were once typically made of a metal ball and a polyethylene (plastic) socket. Over time, hard metal can wear away soft plastic. But ceramic is very hard and provides more longevity for an artificial hip.
Ceramic may be used for both the ball and the lining of the socket (ceramic on ceramic) or just the ball. Other parts may be made of either metal or plastic, ceramic on metal, or ceramic on plastic (polyethylene).

Shows that ceramic-on-ceramic bearings decrease wear, bone, and muscle loss, and lower the risk of dislocation. The human body also tolerates ceramic well, with low reactivity and no toxicity. Research shows that ceramic hip replacements may be preferable to metal or plastics, as ceramic is more durable and may last longer.
There are some limitations for ceramic materials, including a risk of fracture during implant. Improvements in modern materials have made fractures less of a concern today. But it is still difficult to revise a fractured ceramic implant, as there may be many tiny fragments.
A small percent of people who get a ceramic-on-ceramic hip replacement report squeaking sounds similar in sound to the creaking of a door hinge coming from their hip.
Experts do not universally agree as to the best material for hip replacement. A surgeon will assess the advantages and disadvantages of each material for your case before making a decision.
Dr Arun Reddy Mallu who is one of the best hip replacement surgeons in Hyderabad, practices at Continental hospitals,Gachibowli. He generally prefers ceramic head and cross linked poly in young individuals.
