Pincus D, et al. - Researchers tried to find out whether an anterior approach is correlated with lower risk of complications than either a lateral or posterior approach. Between April 1, 2015, and March 31, 2018, a population-based retrospective cohort study was conducted to include all adults in Ontario, Canada, who underwent primary total hip arthroplasty (THA) for osteoarthritis. Follow up period was one-year for all individuals (study end date, March 31, 2019). The total number of individuals included in the study were 30, 098 (mean [SD] age, 67 years [10.7 years]; 16 079 women [53.4%]). An anterior surgical technique compared with a posterior or lateral surgical method was correlated with a small but statistically significant increased risk of major surgical complications among individuals undergoing total hip arthroplasty. Although future study is required to understand pain and functional results, the data may help inform decisions about surgical technique for hip arthroplasty.
