Total joint replacement improves pain, functional quality of life, and health utilities in patients with late-stage knee and hip osteoarthritis for up to 5 years

• This study reports the long term outcomes of hip and knee replacement surgery in late-stage OA.• We identified pre-, per-, and post-operative determinants which contribute to a greater improvement in pain and function, hence increasing patients' satisfaction.• These results could contribute to select an OA population which has a high probability to get an optimal benefit from total joint replacement.
