Status des Projekts abgeschlossen



Fragestellung(en) To investigate the response rate and predictors of treatment success in patients with osteoarthritis treated with primary hip arthroplasty (HA) according to (A) the OMERACT-OARSI responder criteria and (B) the minimal important difference (MID) in generic quality of life (EQ-5D).
Hintergrund / Ziele Osteoarthritis is one of the most common causes of chronic musculoskeletal pain and severe restriction in mobility in the population worldwide. Total joint replacement is an established treatment for advanced osteoarthritis and has the potential to lead to substantial improvement in patient’s functional status and quality of life, thus predictors for success need further Investigation.
Methodik We conducted a register-based cohort study including all patients undergoing primary HA due to osteoarthritis between 01/2006 – 12/2011 at a large tertiary care facility in Germany. Primary outcomes were the change in Western Ontario and McMaster Universities Arthritis Index (WOMAC), the response criteria of the combined initiatives of the Osteoarthritis Research Society International (OARSI) and Outcome Measures in Rheumatology (OMERACT) (OMERACT-OARSI) and the MID in quality of life (EQ-5D) between baseline (prior to surgery) and 6-month follow-up. Various socioeconomic and clinical predictors (e.g. educational level, BMI, Kellgren-Lawrence grade) on treatment success were analyzed by bivariate and multivariate regression methods.
