SAN FRANCISCO — In this video from the Arthroscopy Association of North America Annual Meeting, Andrew E. Jimenez, MD, discusses predictors of return to sport among high-level athletes who underwent hip arthroscopy.
Jimenez and colleagues categorized high school, college and professional athletes into groups based on whether they returned to sport at the same or higher level or either returned to sport at a lower level or did not return to sport after hip arthroscopy. Jimenez noted athletes with higher postoperative outcome scores and lower postoperative alpha angles returned to sport after hip arthroscopy. He added athletes with an alpha angle less than 46° postoperatively were six times more likely to return to sport compared with athletes with postoperative alpha angles greater than 46°, according to results of a receiver operator characteristic curve.
“The way we interpreted this was that it seems that doing an adequate femoroplasty or taking down the cam lesion does have a positive influence on outcomes, not only in the general population but, as this study showed, in athletes who are trying to return to sport,” Jimenez, assistant professor of orthopedic surgery and sports medicine in the department of orthopedics at Yale School of Medicine, told Healio. “We would put a note of caution out there that we’re not trying to put this study out to encourage an over-resection of doing a femoroplasty, but we definitely think it’s important to do a careful restoration of the femoral head-neck junction and restoring the offset to get these patients the best results.”
