Meniscal root tears are soft-tissue and/or osseous injuries characterized by an avulsion of, or tear within 1 cm of, the native meniscal insertion1. These injuries account for 10% to 21% of all meniscal tears, affecting nearly 100,000 patients annually2. Medial meniscal posterior-root tears (MMPRTs) expose the tibiofemoral joint to supraphysiologic contact pressure, decreased contact area, and altered knee kinematics similar to a total meniscectomy3. This injury predisposes the patient to exceedingly high rates of osteoarthritis and total knee arthroplasty secondary to an inability to resist hoop stress4. The arthroscopic transosseous repair of an MMPRT is described in the present article.
