Causal relationship between the gender of patients who underwent hip arthroplasty with regard to affected hip, previous diagnosis, type of arthroplasty and hospitalization duration is analyzed by a retrospective and cross-sectional study with 100 patients from an orthopedic clinic, who underwent total (THA) and partial (PHA) hip arthroplasty. The sample was collected between March 2018 and January 2019. The analysis consisted of a comparative causal model between males and females through propensity score. The covariates were illustrated by the Directed Acyclic Graph (DAG). The patient’s gender was causally associated with the affected hip (p = 0.038), previous diagnosis - osteoarthritis or femoral neck fracture (p = 0.004) and duration of hospitalization (p < 0.001), but failed to explain the hip arthroplasty type (p = 0.385). The left hip was more affected in males (71%), whilst females had a prevalent diagnosis of femur fracture (69.3%) and osteoarthritis in males (65.7%). Further, 71% of males underwent THA, similar to females. Males were hospitalized for -2.12 days less than females. Gender had a causal relationship with affected hip, previous diagnosis, and length of stay in THA, but it was not associated with type of arthroplasty.
