“…The natural course of MMPRT is unknown, but premature and extensive degeneration is a common feature5,6,7,17). Sung et al18) compared the incidence of spontaneous osteonecrosis between patients with MMPRTs and those with medial meniscus posterior horizontal tears: the incidence of osteonecrosis and the extent of meniscal extrusion were significantly greater in the knees with MMPRTs. In a study that investigated the association between medial meniscus tears and arthritic degeneration, Henry et al17) showed statistically significant relationship between root and radial/flap tears and degenerative changes in the medial femoral condyle and between root and complex tears and degeneration of the medial tibial condyle.…”

Damage to the medial meniscus root, for example by a complete radial tear, destroys the ability of the knee to withstand hoop strain, resulting in contact pressure increases and kinematic alterations. For these reasons, several techniques have been developed to repair the medial meniscus posterior root tear (MMPRT), many of which have shown complete healing of the repaired MMPRT. However, efforts to standardize or optimize the treatment for MMPRT are much needed. When planning a surgical intervention for an MMPRT, strict surgical indications regarding the effect of pullout strength on the refixed root, bony degenerative changes, mechanical alignment, and the Kellgren-Lawrence grade should be considered. Although there are several treatment options and controversies, the current trend is to repair the MMPRT using various techniques including suture anchors and pullout sutures if the patient meets the indications. However, there are still debates on the restoration of hoop tension and prevention of arthritis after repair and further biomechanical and clinical studies should be conducted in the future. The aim of this article was to review and summarize the recent literature regarding various diagnosis and treatment strategies of MMPRT, especially focusing on conflict issues including whether repair techniques can restore the main function of normal meniscus and which is the best suture technique to repair the MMPRT. The authors attempted to provide a comprehensive review of previous studies ranging from basic science to current surgical techniques.

“…Transection injuries of the posterior meniscal root lead to serious consequences similar to those of total meniscectomy and a near-total loss of biomechanical function of the meniscus [5,9,18,20]. As a result, degenerative chondral wear can progress rapidly due to decreased tibiofemoral contact area and increased contact pressure.…”

“…1 In clinical studies, PMMRTs were associated with high-grade chondral lesions, 13 with osteonecrosis, 14,15 and with the incidence and progression of osteoarthritis (OA). 16 Because nonoperative treatment and partial meniscectomy have shown unsatisfactory results, 9,17,18 surgical reattachment of the posterior medial root is increasingly performed.…”
