CHICAGO, IL – Outcomes after surgery have always been difficult to determine. Now a new case
study on more than 500 hip procedures highlights that complication rates may be even higher than
previous reports, say researchers presenting at the American Orthopaedic Society for Sports
Medicine’s Specialty Day in Chicago, IL.
“The overall complication rate after hip arthroscopy was 7.2 percent, which is higher than what has
been previously reported in the literature at 1.5 percent,” said lead author Christopher Larson, MD of
the Minnesota Orthopaedic Sports Medicine Institute in Minneapolis. “Our multicenter study trial is
one of the first to evaluate complication rates for all arthroscopic hip procedures using a grading
scheme that evaluated the possibility of complications based on demographic and surgical data.
Previous reports on complications were prior to new surgical techniques such as labral repair and
treatment of femoroacetabular impingement (FAI) or were not comprehensive.”
Between January 2011 and April 2012, Larson and his team, evaluated 573 individuals (287 males,
286 females) with a mean age of 32.3 years who underwent hip arthroscopy (minimally
invasive surgical procedure in which an examination and sometimes treatment of damage of the
interior of a joint is performed using an arthroscope) at three institutions. The diagnosis, demographic
information and procedures were recorded, and a validated complications grading classification was
used for all patients prospectively.
“The most common adverse event after surgery (22.7% of hips) was post-operative sensory
disturbance in the leg and only persisted beyond six months in four hips and was considered a
sequelae rather than a complication. There was no difference in complications between males vs.
females, primary vs. revision, labral repair vs. debridement and BMI,” said Larson. “We hope that our
research helps to provide new insights into surgery complications and how to prevent them.”
The American Orthopaedic Society for Sports Medicine (AOSSM) is a world leader in sports medicine
education, research, communication and fellowship, and includes national and international orthopaedic
sports medicine leaders. The Society works closely with many other sports medicine specialists, including
athletic trainers, physical therapists, family physicians, and others to improve the identification, prevention,
treatment, and rehabilitation of sports injuries. AOSSM is also a founding partner of the STOP Sports
Injuries campaign to prevent overuse and traumatic injuries in kids. For more information on AOSSM or the
