Hip arthroplasty involves replacing the diseased joint with a metal prosthesis.
It is usually recommended in cases of hip osteoarthritis.
Initially, based on the findings of the radiological examination, the damaged femoral head is removed.
Then, the specialized orthopedic surgeon creates a recess in the pelvis in order to place the special cup in which the artificial femoral head will abut and function. Finally, it properly prepares the femoral lumen in order to receive the 
metal stem on which the artificial head will be supported.
The prosthesis anatomically resembles the normal hip and ultimately the prosthesis – bone – joint assembly functions like a normal joint.
The artificial joint – all of whose materials are completely compatible with the human body – consists of either special durable plastic and highly durable metal alloys of steel and titanium, or of metal surfaces of cobalt – chromium (metal on metal).
The total hip arthroplasty procedure lasts 1-2 hours.

Hip Arthroplasty
This specific method of arthroplasty is applied to patients with hip osteoarthritis but also to patients with osteonecrosis of the joint.
The main difference of this invasive technique compared to the classical arthroplasty method lies in the fact that the femur is not completely removed, but rather the affected parts of the cartilage are removed.
For this specific arthroplasty method, a cap-head prosthesis made of a special metal alloy is used, which is completely compatible with the human body.
