Salari P, et al. - A retrospective review study was conducted to prognosticate lateral meniscal injury in tibial plateau fractures, based on location and extent of AID as visualized on pre-op CT images. Researchers retrospectively examined lateral tibia plateau fracture patients that were treated operatively using CPT codes 27535 and 27536. They distinguished 200 individuals. There is a 21% increase in the chance of meniscal tear, with a 1mm increase in AID. It was reported that with the same AID, AL and AM zone fractures have a significantly higher chance of having a meniscal tear. In lateral tibia plateau fracture, AID of 4.3mm provides 100% sensitivity to predict meniscal tear. These values are beneficial in prognosticating pre-op meniscal tear without MRI.
