Abstract

Objective: Describe the characteristics of some complications after hip replacement surgery. Methods: A cross-sectional descriptive retrospective study. Describe some characteristics in 287 patients diagnosed as one complication after hip replacement surgery from May 2016 to May 2021 at Bach Mai Hospital and VietDuc University Hospital. Results: Mean age 61.12 ± 13.27, the percentage of men accounted for the majority (62.37%). Patients with postoperative infection accounted for the highest rate at 41.81%, prosthesis dislocation at 26.48%, prosthesis loosening at 20.56%, and limb length difference postoperative at 11.15%. The median time of postoperative infection: is 14.38 months, mostly in the early and delayed stages. In which the most common clinical symptom is fever accounting for 58.33%, 51.67% of patients had inflammatory symptoms, 55.83% of patients had sinus tract symptoms. Average erythrocyte sedimentation 1-hour rate: 47.84±13.37mm. 78.33% of patients had positive microbiological culture results. Regarding prosthesis dislocation complications, average time of prosthesis dislocation: 3.8 months. In which the main cause of dislocation was due to  daily activities (80.26%). Mean time of appearance of prosthesis loosening: 10.42 years. 83.05% of patients with prosthesis loosening have pain symptoms, 89.83% have limited range of motion. Mainly patients with loose stems accounted for 59.32%. The mean limb length difference in the complication group was 14.22 ± 5.84mm. Conclusion: Although hip replacement surgery has many advantages such as helping patients reduce pain and improve movement function of the hip joint, helping patients return to activities soon after surgery, etc., surgeons also necessary to pay attention to the possible complications and complications to explain carefully the patient as well as the patient's family before surgery.
