Many hip problems, particularly degenerative and inflamatuary hip diseases, result in hip pain and restriction of motion. The main demand of patients is to relieve pain and regain hip motion. Total hip arthroplasty (THA) is among the most successful orthopaedic surgeries. In parallel with the improvements in bioengineering, the implant materials have been manufactured which are expected to be more durable and longstanding. Besides nowadays, instead of accepting the pain and restricted activity as it is, patients demand to get rid of their pain completely and continue their normal bodily function. Therefore, currently there is an increase in number of THA applications. In the early treatment of the hip diseases, conservative measures should be used in principle. Giving weight, utilizing a cane, taking analgesics, modifying and restricting some activities should be the initial proposals to the patient. THA should be recommended if these conservative measures fail. The primary indication of THA is the pain in the presence of a destructive process in the hip joint as evidenced on radiographs. Active infection in the hip joint or elsewhere in the body are accepted as decisive contraindication. Charcot arthropathy, an absence or insufficiency of abductor musculature, demantia and successful hip arthrodesis are accepted as relative contraindications. THA is a major surgery and should always be the last option for treatment. Therefore, being meticulous during the indication and selection of the patient will increase the success of THA.
