Transosseous Medial Meniscal Root Repair Using a Modified Mason-Allen Suture Configuration

Medial meniscal tears are among the most common injuries to the knee joint. Loss of the meniscus has been linked to increased contact pressures on the adjacent articular cartilage and progression of degenerative changes in the knee. A subset of tears known as “root tears” involves the insertion of the posterior horn of the meniscus to the bone. Arthroscopic partial meniscectomy for root tears led to undesirable outcomes, which prompted surgeons to explore restorative procedures. Multiple repair techniques have been presented with an emphasis placed on initial secure fixation and stimulation of potential healing. We present an arthroscopic-assisted technique for medial meniscal root repair with these goals in mind
