Introduction and Purpose: Hip arthroplasty is one of the most useful nonemergency orthopedic surgeries, which is effective in improving pain and function in patients with joint disabilities, and due to its serious complications, as well as the significant and increasing need for research in this field, it seems necessary. This study was conducted with the aim of investigating the type of surgery and the results of joint replacement treatment in patients with orthopedic trauma referred to Baqiyatalla Hospital from 1391 to 1401.

Materials and Methods: This study was conducted cross-sectional. All patients with orthopedic trauma who underwent hip arthroplasty and who visited Baghiy a Hospital between 1391 and 1401 were included in the study. The outcomes investigated in this study are demographic information, treatment complications (infection, loosening, and per prosthetic fracture), patients' final performance, Harris hip score and Womac index. All the information of these patients was extracted from the files in Baqiyat Hospital and finally entered into STATA version 15 software for analysis and comparison. collecting quantitative data, it was analyzed with the help of spss software version 19.

Result: Age of patients in patients who underwent total hip arthroplasty and hip arthroplasty were 67.71 years ± 7.19 years and 79.37 years ± 7.14 years respectively, 67 (49.3%) men and 69 (50.7%) women were studied, the average body mass index in total hip arthroplasty and knee hemi arthroplasty patients respectively It was 24.88 ± 1.56 and 23.85 ± 1.34 in hip arthroplasty patients in 1 case (0.7 percent) and in hip hemi arthroplasty patients it was not observed in any case. The average Harris Hip Score (HHS) in total hip arthroplasty and knee hemi arthroplasty groups was 76.5 ± 4.8 and respectively. It was 73.7 ± 5.1. Six people died in total hip arthroplasty during one year, but this number was recorded in ten people in hip hemi arthroplasty. Most of the patients in both groups were in grade two American Society of Anesthesiologists (ASA) Score, so that in this grade, there were 66 people (48.5%) in total hip arthroplasty and 42 people (30.9%) in hip hemi arthroplasty. Between gender (p=0.574), infection (p=0.98), lossening (p=0.15), displacement (p=0.42) and fracture (p=1), smoking (p=0.51), reoperation (p=0.09), falling from a height (p=0.52). ASA Score (0.05) did not find any statistically significant difference between the two groups. However, patients' age (p=0.00), Body Mass Index (BMI) (p=0.00), underlying disease (p=0.03), Harris Hip Score (HHS) (p=0.002), deaths (p=0.04), there was a statistically significant difference.

Conclusion: The result of our study showed that in the group that underwent total hip arthroplasty, they were younger and had a lower body mass index. They had a higher HHS score and a lower number of deaths than the group that underwent hip hemi arthroplasty.
