Does Surgical Approach in Total Hip Arthroplasty Affect Rehabilitation, Discharge Disposition, and Readmission Rate?
Department of Orthopaedic Surgery Wake Forest School of Medicine Winston-Salem, North Carolina.Surgical technology international 05/2013; XXIII.
There is a substantial preoccupation with different surgical approaches and minimally invasive techniques that may improve clinical outcomes for patients who undergo total hip arthroplasty. This study assessed the impact on hospital-related outcomes of the direct anterior approach (DAA) compared with the posterior approach (PA) performed by a single surgeon in 100 consecutive patients in each cohort. Patient age was similar in the DAA (61 ± 1.1 years) compared with the PA (62 ± 1.3, p = 0.733); however, BMI tended to be lower in DAA patients (29.1 ± 0.8) compared with PA patients (31.3 ± 0.7, p = 0.057). The DAA compared with the PA was associated with significantly less blood loss (285 ± 15 vs. 367 ± 21ml, p = 0.002) and transfusions (18 vs. 39 units, p = 0.009), less narcotic usage on postoperative days 1-3 (101 ± 12 vs. 146 ± 12 morphine equivalent dose, p = 0.010), a quicker hospital discharge (70 ± 3.3 vs. 97 ± 5.5 hours, p < 0.001), and a more favorable disposition (97% vs. 84% discharged home, p = 0.003). Thirty-day readmission rate was significantly higher with the PA (9%) compared with the DAA (1%, p = 0.030). The number of cups in the safe zone (5° to 25° anteversion and 30° to 50° inclination) was significantly higher with the DAA (92%) compared with the PA (75%, p = 0.002), possibly attributed to fluoroscopy used with the DAA. The DAA muscle-preservation technique may have led to the benefits observed in this study compared with the muscle-splitting technique associated with the PA.

ABSTRACT: The objective of this study is to compare the clinical, radiographic and surgical outcomes among patients undergoing primary THA performed via the anterior versus posterior approach. We searched numerous sources and eventually included 17 studies, totaling 2302 participants. In terms of post-operative pain and function, the anterior approach was significantly favored in 4 studies at short-term follow-up. Pooled estimates showed a significant difference in favor of the anterior approach in terms of length of stay and dislocations. Current evidence comparing outcomes following anterior versus posterior THA does not demonstrate clear superiority of either approach. Until more rigorous, randomized evidence is available, we recommend choice of surgical approach for THA be based on patient characteristics, surgeon experience and surgeon and patient preference.

Article: Options for Primary Hip Arthroplasty[Show abstract] [Hide abstract]
ABSTRACT: Total hip arthroplasty (THA) is widely regarded as one of the most successful procedures in orthopedic surgery. It signifi cantly reduces pain, increases mobility, and restores function to patients who are otherwise incapacitated by degenerative joint disease. In addition, THA has a cost/utility ratio that rivals treatments for hypertension and coronary artery disease making it one of the most cost-effective medical interventions known [1, 2]. Despite this, an ever-increasing life expectancy and greater patient expectations for post-surgical activity have spurred advances in design and surgical technique which seek to increase the longevity of the prosthesis while minimizing morbidity. Such developments are crucial to reducing revision rates in THA patients who are younger and may require multiple revisions in their lifetime.

ABSTRACT: We evaluated the quality of information available on the Internet regarding the direct anterior approach (DAA). The top 50 Web sites from three major search engines (Google, Yahoo!, and Bing) were tabulated utilizing the search term direct anterior hip replacement. Of these, only 22% were authored by a hospital/university, while 60% were by a private physician/clinic. Most Web sites presented the DAA as "better" than other surgical approaches describing benefits, such as accelerated recovery though only 35% described risks of the approach. While only 39% of sites presented patient eligibility criteria, greater than 75% had the ability to make an appointment. Web sites regarding the DAA provide patients with a limited perspective and may be focused on attracting new patients, as opposed to accurately educating them. Copyright © 2015.
