Abstract: BACKGROUND: Recurrent prosthetic dislocation after total hip arthroplasty with posterolateral approach is one of the serious complications that affect the quality of life of patients, and it is also a problem faced by clinicians. At present, the analysis of the influencing factors of repetitive prosthesis dislocation is still relatively small, so the reason for the concurrent repetitive prosthesis dislocation is not clear in the academic circles.  
OBJECTIVE: To analyze the risk factors of recurrent prosthetic dislocation after total hip arthroplasty through posterolateral approach.
METHODS: 142 patients who underwent total hip arthroplasty through posterolateral approach in Subei People’s Hospital of Jiangsu Province were collected. According to the dislocation within 2 years after operation, patients were divided into non-dislocation group (n=54), single dislocation group (n=50), and repeated dislocation group (n=38). The risk factors that may lead to postoperative dislocation of the prosthesis and the development of repetitive prosthesis dislocation were collected and analyzed. Logistic regression analysis was used to analyze the factors affecting repetitive prosthesis dislocation, and then to summarize the relevant independent risk factors.  

RESULTS AND CONCLUSION: (1) There was no significant difference in gender, chronic disease history, and body mass index among the three groups of patients (P > 0.05). There were significant differences in age, history of early dislocation, history of neurological diseases, femoral prosthesis diameter, acetabular abduction angle, and femoral anteversion angle and whether it was normal (P < 0.05). (2) Compared with the single dislocation group, patients in the repeated dislocation group had a significantly higher probability of early dislocation, neurological disease and abnormal anteversion angle (P < 0.05), and the diameter of the femoral head prosthesis was significantly reduced (P < 0.05). (3) Logistic regression analysis showed that the patient’s age, history of neurological diseases, history of early dislocation, whether the femoral anteversion angle was normal, and the diameter of the femoral head were correlated with repeated prosthetic dislocations after total hip arthroplasty (P < 0.05). (4) The results showed that the patient’s advanced age, whether the first dislocation was an early dislocation, whether it was complicated by neurological disease, whether the femoral anteversion angle was normal, and the diameter of the femoral head may be risk factors for recurrent prosthesis dislocation after total hip arthroplasty through posterolateral approach
