J&J’s DePuy Synthes touts anterior-approach results in comparative THA study

Johnson & Johnson (NYSE:JNJ) subsidiary DePuy Synthes today touted results from a systemic review of prospective studies comparing postoperative outcomes of both anterior and posterior approaches to total hip arthroplasty procedures.

Results from the study, which were published in The Journal of Arthroplasty, indicated that the anterior approach results in increases in hip function and reduction in pain and narcotics use compared to the posterior approach, and that complication rates between the both approaches showed no statistical differences through 90 days.

“Our goal with this research was to rigorously evaluate outcomes of anterior approach and posterior approach from the highest quality prospective studies performed to date. We found that THA using the anterior approach provided clinically important benefits to patients compared to Posterior Approach over 90 days follow-up,” lead study author Dr. Larry Miller said in a prepared statement.

DePuy Synthes said that previous comparative reviews relied on data from retrospective studies, and that its meta-analysis included a total of 13 prospective comparative studies, including more than 1,000 patients treated with boath approaches.

In the meta-analysis, researchers looked to address components of the Comprehensive Care for Joint Replacement model, including complication rate, patient satisfaction and pain management over 90 days.

“While the posterior approach is still the most widely used technique worldwide, we see growing interest in the anterior approach. This study builds on the mounting evidence that the anterior approach supports the goals of improving outcomes, optimizing the patient experience and reducing the overall cost of care,” DePuy Synthes health economics and market access US head and study co-author Samir Bhattacharyya said in a press release.

Last month, DePuy Synthes said it closed its sale of Prodisc assets to Centinel Spine for an undisclosed amount.
