Introduction: Nowadays, total hip replacement is a highly effective surgical procedure in healthcare systems. Even though this procedure provides very effective outcomes, complications in many times are inevitable. Methods: This observational study focused on the collection of data regarding the complications that occurred in patients who underwent Total Joint Arthroplasty for a period of 5 years. The data are collected from the arthroplasty registry in the University Trauma Center Hospital. All the major and minor procedure complication findings are analyzed by SPSS software 20.0. The logistic regression was used to identify some of the risk factors for complications A p-value of <5% was statistically significant. Results: Overall of 812 patients, over 50 years old, who underwent total hip arthroplasty, about 62.9% were women, and the most predominant age 71-80 years old was. Women were more likely to be older and to have hypertension, anemia, and kidney disease compared to men (P < 0.02). The rate of major and minor complication procedures was reported at 2.4% and 5.5% respectively. A significant association was seen between risk factors such as BMI, syndrome metabolic, and previous THA. The most predominant complications were dislocations 1.8%, infections 2.5%, leg length discrepancy 1%, nerve damage 0.2% and muscle weakness 5.5%. Readmission as a consequence of postoperative complications was reported only in 1.2% of patients. Conclusion: The findings of this study, suggest a minor rate of postoperative complication procedures among patients who underwent the intervention for total joint arthroplasty. Furthermore, studies are recommended to clarify the risk factors that influence postoperative complication procedures in total joint arthroplasty patients.
