Study identifies multiple reoperation risk factors after ACL repair
Recently published data have shown low overall short-term reoperation rates following ACL repair.
Researchers studied 14,522 patients with a mean age of 29.4 years who underwent ACL reconstruction. The patients were enrolled in an ACL reconstruction registry between February 2005 and September 2011 at a mean follow-up of 1.9 years. First reoperations for meniscal and cartilage repair, hardware removal and arthrofibrosis occurred at a median of 301 days after primary ACL reconstruction and served as the study’s primary end points. Reoperation rate per 100 person-years of follow-up was 1.1 for meniscal reoperations, 0.3 for cartilage reoperations, and 0.4 for both hardware removal and arthrofibrosis reoperations. They found that meniscal repair was a significant risk factor for subsequent meniscal procedures.
The surgeon’s sports medicine fellowship training and older patient age were found to be significant risk factors for cartilage reoperations. Use of allografts was a significant risk factor for patients who had hardware removal reoperations, and previous surgery was a risk factor for arthrofibrosis reoperations. The researchers also found that female gender was a risk factor for both hardware removal and arthrofibrosis reoperations. — by Christian Ingram
