The knee joint contains two crescent-shaped fibrocartilaginous structures, the menisci (medial and lateral), which serve as shock absorbers and stabilize the joint during movement. Each meniscus has an outer vascular zone (red-red zone), which has a good blood supply and healing potential as well as a central avascular zone (white-white zone ...
Damage to the saphenous nerve and its infrapatellar branch is possible during medial knee surgery, potentially causing numbness or pain over the medial knee and leg. [7] As with all surgeries, there is a risk of bleeding, wound problems, deep vein thrombosis , and infection that can complicate the outcome and rehabilitation process.
A "pop" sound may be associated with this injury, followed by the loss of the ability to straighten the knee (knee extension). Pain at the medial joint line (medial to the inferior border of the patella) indicates medial compartment osteoarthritis, injury to the medial collateral ligament, or a medial meniscal tear.
The knee loses its ability to transmit and distribute load and absorb mechanical shock. Persistent and significant swelling and stiffness in the knee. The knee may be not be fully mobile; there may be the sensation of knee locking or buckling in the knee. The full knee may be in full motion after tear of meniscus.

[7] However, this has no relation to pain and function. [11] [12] Giving-way of the knee may be reported. [7] Reduced knee flexion may be experienced during activities. [13]
The condition is usually characterized by a sudden onset of knee pain, worse at night, or during weight-bearing such as standing or running. Nevertheless, it can also occur during rest or without any weight-bearing. About 94% of the cases affect the medial condyle of the femur. This is because the blood supply for the medial condyle is less ...
