Are there more wound complications or infections with direct anterior approach total hip arthroplasty?Tissot, C., Vautrin, M., Luyet, A., & Borens, O. (2018).
Compared to a lateral or posterior approach (PA), the direct anterior approach (DAA) does permit a better muscle preservation for total hip arthroplasty (THA). However, there is concern whether this advantage come with increased wound complication and infection leading to reoperation or sometimes major procedures.
We retrospectively reviewed all patients who underwent primary THA through the PA between January 2009 and April 2013 (n = 796) and through the DAA between January 2011 and April 2013 (n = 399) at our institution with a minimum of 2 years follow up regarding all wound complications and all infections.
Of the 796 patients in the PA group, there were 6 wound complications leading to reoperation and 6 infections; 4 early and 2 delayed onset. Among the infected cases, one was obese (body mass index [BMI] >30 kg/m2). Two procedures were teaching-based. Of the 399 patients in the DAA group, there were three dehiscences leading to reoperation, two of which were in obese patients. 6 infections were also found; 4 with early and 2 with delayed onset. Of the infected cases, three were obese. 4 procedures were teaching-based.
In our series of patients undergoing THA, the DAA did not increase the rates of either wound complications leading to reoperation nor early or delayed infection compared to the PA.
