According to a recent study published in the Journal of Bone & Joint Surgery (JB&JS), The Effect of Surgical Approach and Femoral Prosthesis Type on Revision Rates Following Total Hip Arthroplasty, compared with other total hip arthroplasty (THA) approaches, the anterior approach has an increased rate of revision for femoral-sided complications – certain stems increasing this risk. In this study, the authors assessed the outcome of THA by surgical approach, according to the femoral stem utilized in the procedure.
The study included 48,716 THAs performed with use of cementless stems, of which 22,840 utilized an anterior approach and 25,876 utilized a posterior approach. THAs performed via the anterior approach had higher rates of revision for femoral stem loosening and fracture, with greater variation in outcomes between individual stems.
