“…The landmarks for the posterior horn attachment of the medial meniscus are the PCL, the medial tibial spine, and the articular margin of the posteromedial tibial plateau. 24,33 Two patients with posterior horn root avulsions of the medial meniscus and meniscus extrusion underwent arthroscopic primary repairs of the posterior horn of the medial meniscus using sutures through a transosseous tunnel and realized excellent short-term results. The current study was designed to provide laboratory biomechanical evidence of the procedure's ability to return hoop stress resistance and to provide basic science evidence to support the early clinical success of the operation.…”

“…Therefore, knowledge of insertional anatomy of the lateral meniscus is imperative when performing meniscal transplantation. Urban et al 10 reported that the anterior horn of the lateral meniscus inserts 0.48 cm lateral to the tibial midline and the posterior horn inserts 0.51 cm medial to the tibial midline on the coronal plane from 13 cadaveric specimens. They found that the anterior and posterior horns were almost inserted to the midline of the tibial plateau.…”

This study investigated the internal fluid pressure of human cadaver meniscal root attachments. A pressure micro-sensor was implanted inside each attachment site. Tibiofemoral joints were compressed to 2x body weight at various flexion angles and pressure recorded for 20 minutes. The anterior cruciate ligament (ACL) was then transected and joints retested. Lastly, a longitudinal incision of the lateral posterior horn was made and the joint retested. Ramp pressure was defined as the pressure when 2x body weight was reached, and equilibrium pressure was recorded at the end of the hold period. The medial posterior attachment was subjected to greater ramp pressure than the medial anterior (p=0.002) and greater equilibrium pressure than all other root attachment sites (p<0.001). Flexion angle had a significant effect on pressure as full extension was greatest at ramp (p=0.040). Transection of the ACL decreased ramp pressure in the lateral posterior attachment (p=0.025) and increased equilibrium pressure (p=0.031) in the medial posterior attachment. The results suggest that repair strategies should be developed which reconstruct the medial posterior attachments to be sufficient to withstand large pressures. Furthermore, since meniscal pressure is highest at full extension, this fact should be considered when prescribing rehabilitation following repair of an attachment.
