Incidence of Reasons for Revision Hip Surgery: Preliminary Study

INCIDENCE OF REASONS FOR REVISION HIP SURGERY: PRELIMINARY STUDY (Abstract). Aim: To analyze the main causes and short/mid-term clinical outcomes of revision total hip arthroplasty. Material and Methods: All patients treated over a period of 36 consecutive months at the Orthopedic Clinic of the Iasi Rehabilitation Hospital were an alyzed. The causes for total hip arthroplasty (THA) failure were grouped into one of the six categories: aseptic loosening, infection, dislocation, component wear, periprosthetic fracture, and pain. Results: The rate of risk for THA failure is differently influenced by factors such as age, weight index, associated comorbidities, gender, and physical activity level. Most r evisions (72.4%) were for aseptic loosening. Age group distribution showed that most p atients who required revision, regardless of age group, were women. Conclusions: Although the risk of infection is higher in the first six weeks after surgery, early infections rarely r equire partial or total replacement of the prosthesis. Infections that require prosthesis revision are late and deep, but the incidence of such complications is low. Loosening is the most common cause of THA failure.
