Abstract

This retrospective study investigated the impact of patient and procedure-related parameters on the complication rate following revision total hip arthroplasty. Complications included vessel and nerve damage, periprosthetic femoral fracture, wound infection, wound bleeding, prosthesis dislocations, thromboembolism, cardiac and pulmonary complications, and death. The influence of operation duration, gender, revision status, ASA classification, and type of fixation of the primary implant on the perioperative morbidity was investigated in a sample of 60 revision procedures (cemented stems, cemented or cementless cups). Odds ratio [OR] and 95% confidence interval [CI] were estimated with multiple regression models. Perioperative morbidity was significantly correlated to operation duration (OR = 1.03; CI: 1.00-1.05), but not to age (OR = 1.01; CI: 0.93-1.09), gender (OR = 2.66; CI: 0.50-14.05), revision status (OR = 2.34; CI: 0.54-10.05), ASA classification (OR = 1.24; CI: 0.30-5.18), or type of fixation of the primary implant (OR = 2.49; CI: 0.47-13.17) Duration of the revision operation appeared as a predictive parameter for perioperative morbidity in revision total hip arthroplasty in our study group.
