Although some reports have described successful repair of the avascular portion of the meniscus,11 it is generally accepted that meniscal repair is more likely to be successful if it involves or at least communicates with the meniscal red zone, lying within three to four millimeters of the capsular rim.12 A basic principle of meniscal repair is to rasp the tear edges and the parameniscal synovium above and below the meniscus, which is thought to enhance the vascular healing process.

PDF Meniscal Ramp Lesions Physical therapy should start immediately after surgery and include early passive range of motion from 0 to 90 for the initial 2 weeks and progress to full range of motion thereafter. Magnetic resonance imaging can also be effectively used to estimate the vascular zone classification (see Treatment) of tears.18 This is useful for the orthopaedic surgeon to predict meniscal repairability, assisting informed discussion with patients and scheduling appropriate operating theatre time.18 It is essential to remember that just because a tear can be seen on MRI, this does not mandate surgery.
