MMPRT
Pain behind the inner knee — a tear at the "root" of the meniscus
The meniscus is a C-shaped cushion between the thighbone and shinbone inside the knee.
MMPRT occurs when the "root" (attachment point) of the medial meniscus tears away from the bone.
When the root tears, the meniscus loses its ring-like tension (hoop stress), and its cushioning function drops significantly.
Over time, meniscal tissue degenerates and becomes more fragile
Bow-legs and excess weight place chronic stress on the medial compartment
Deep squats and standing up put significant force on the posterior root
The meniscus slips out of position and extrudes beyond the joint (meniscal extrusion), leaving cartilage exposed to direct load
Conservative treatment may relieve pain, but full recovery of meniscal function can be difficult. If left untreated, the progression to osteoarthritis may accelerate. Treatment choice is based on a comprehensive evaluation of age, activity level, and cartilage condition.
