Meniscal deficiency shown to predict graft failure in ACL reconstruction
For single-bundle anatomic ACL reconstruction, meniscal deficiency was shown as the most significant factor to predict graft failure, according to a study performed at University Hospitals Coventry and Warwickshire.
To determine factors associated with subjective and objective measures of graft failure, investigators studied primary, anatomic ACL reconstructions performed at a single institution during a 2-year period. Time since ACL rupture, intact or deficient medial and lateral menisci, and meniscal repair were among the risk factors investigators assessed by 3-D CT scan during a postoperative follow-up of 123 patients. Patients had a median follow-up of 26 months.
At the final follow-up, 20 ACL constructions were classified as failures. These included 15 graft re-ruptures and five had a grade 2 pivot-shift test with an intact graft. There were 77 patients with successful ACL reconstructions, while the remaining number of patients with successful reconstructions did not have a CT scan for the study.
Investigators found patients with medial meniscal deficiency had a hazard ratio of 15.1 for graft failure. Lateral meniscal deficiency, shallow nonanatomic femoral tunnel positioning and younger patient age showed hazard ratios for graft failure of 9.9, 4.3 and 0.9, respectively. – by Rhiannon Bulaga
