The incidence of initial anterolateral ligament injury seen on MRI was not different in patients who had a subsequent ACL graft rupture after primary ACL reconstruction vs. patients who did not experience ACL graft rupture, according to recently published results.
Researchers used their institution's electronic medical record database to identify 1,967 patients who underwent primary ACL reconstruction with subsequent ACL graft ruptures. Patients were paired with an age-, sex, and graft-matched control who underwent ACL reconstruction without subsequent graft ruptures. On the initial MRI, patients were diagnosed with either an intact, partially injured or full ruptures of the anterolateral ligament (ALL). Investigators also noted the location of the ALL injury. The χ2 analysis was used to compare the incidence and location of ALL rupture.
Results showed there were 128 patients with an ACL graft rupture. There were 55 patients who had MRI scans available to review, of which 39 patents met the inclusion criteria and were matched with a control patient. The ALL in the revision group was diagnosed as intact in 17 patients, partially torn in 14 patients and completely torn in eight patients. However, in the control group the ALL was diagnosed as intact in 18 patients, partially torn in 13 patients and completely torn in eight patients. There was no difference seen in the frequency of ALL rupture and rupture location. – by Monica Jaramillo
