The purpose of this study is to compare the effect of total hip arthroplasty and conservative treatment to hip pain, to activities of daily life and to the quality of life in patients with hip osteoarthritis.


The purpose of this randomized controlled study is to compare the effect of total hip arthroplasty and conservative treatment (that consists of self-driven exercises that physical therapists teach to the patients) to hip pain, to activities of daily life and to the quality of life in patients with hip osteoarthritis. Also the ill effects and cost effectiveness of total hip arthroplasty and conservative treatment are evaluated. Further more the aim is to investigate if total hip arthroplasty alleviates osteoarthritic pain in 12-month follow-up and if it enhances performance and quality of life.
