Aims

Use of the direct anterior approach (DAA) for total hip arthroplasty (THA) has increased in recent years due to proposed benefits, including a lower risk of dislocation and improved early functional recovery. This study investigates the dislocation rate in a non-selective, consecutive cohort undergoing THA via the DAA without any exclusion or bias in patient selection based on habitus, deformity, age, sex, or fixation method.

Methods

We retrospectively reviewed all patients undergoing THA via the DAA between 2011 and 2017 at our institution. Primary outcome was dislocation at minimum two-year follow-up. Patients were stratified by demographic details and risk factors for dislocation, and an in-depth analysis of dislocations was performed.

Background

The use of the direct anterior approach (DAA) for total hip arthroplasty (THA) has increased in recent years. This is in part due to the proposed benefits of a faster early recovery and a lower risk of dislocation. The purpose of this study is to understand the dislocation rate in a non-selective, consecutive cohort of patients undergoing THA via the DAA including those at high risk for instability due to spinopelvic pathology.

Methods

We performed a retrospective review of a large prospectively collected single institution database assessing all patients undergoing THA via the DAA between 2011 and 2017. The primary outcome measure was dislocation at minimum two-year follow-up. We then stratified patients by known risk factors for dislocation including spinopelvic pathology and performed an in-depth analysis of those patients who had a dislocation event.

Background

Routine closed suction drainage and postoperative laboratory studies have long been tenets of most TJA protocols. However, recent literature has called into question whether either is necessary with modern outpatient TJA clinical pathways.

Methods

Demographic, cost, and readmission data for 2,605 primary unilateral TJA cases was collected retrospectively and analyzed prior to and after a protocol change where routine closed suction drains and postoperative laboratory tests were eliminated. This protocol change was designed to treat all primary TJA like outpatients regardless of their admission status. Drain usage changed from routine to selective based on hemostasis. Lab studies changed from routine to selective for patients on warfarin for VTE prophylaxis (INR), with ASA 4 or 5 status (BMP), and with a hematocrit < 27% in the recovery room after THA (CBC).
