Surgical Approaches in Total Hip Arthroplasty Cost Per Case Analysis: A Retrospective, Matched, Micro-costing Analysis in a Socialised Healthcare System.

Background: Total hip arthroplasty (THA) offers an effective method of pain relief and restoration of function for patients with end-stage arthritis. The anterior approach (AA) claims to benefit patients with decreased pain, increased mobilisation and decreasing length of hospital stay (LOS). In a socialised healthcare platform we questioned whether the AA, compared to posterior (PA) and lateral (LA) approaches, can decrease the cost burden.
