This is because this area has rich blood supply and blood cells can regenerate meniscus tissue or help it heal after surgical repair. Knees with a deficient medial meniscus and an ACL tear have an increased anterior tibial translation of about 60% at 90 of flexion. With the foot as close to the hip as possible, the clinician holds the knee joint (with fingers along the joint line) with one hand, and the other hand rotates the tibia internally and externally while extending and flexing the knee.

This leads to decreased contact area and increased contact pressure and ultimately results in joint overloading and degenerative changes in the knee similar to a total meniscectomy state. Your meniscus acts like a cushion between your thigh bone (femur) and shin bone (tibia). This tear pattern was historically unrecognized, although more recently it has been suggested this hidden pathology may account for nearly 80% of the total knee replacements in patients younger than 60 years. Tears to the medial meniscal root change the biomechanics and kinematics of the knee, which cause early degeneration of the joint. A torn meniscus often can be identified during a physical exam. The menisci are "wedge-shaped" pieces of cartilage that rest between the thigh bone ("femur") and lower leg bone ("tibia") in the knee joint.

In addition, focal chondral lesions occur more commonly with medial than lateral-sided injuries. During the exam, your doctor will look for signs of tenderness along the joint line. The double posterior cruciate ligament (PCL) sign appears on sagittal MRI images of the knee when a bucket-handle meniscal tear (medial meniscus in 80% of cases) flips towards the center of the joint so that it comes to lie anteroinferior to the posterior cruciate ligament (PCL) mimicking a second smaller ligament.. A double posterior cruciate ligament sign from a torn medial meniscus can . It absorbs about 50% of the shock of the medial compartment. Flaps cause mechanical instability - meaning they interrupt the smooth function of the knee joint and will make your knee joint feel unstable. Although an X-ray will not show a meniscus tear, your doctor may order one to look for other causes of knee pain, such as osteoarthritis. What is Meniscus Radial Tear. (redirected from Oblique Tear) The most common meniscal tear, a type of radial tear which begins at the free (inner) edge like other radial tears, but then curves into a longitudinal orientationsimilar to longitudinal meniscal tearsas the tear extends toward the meniscal periphery. A case also can be made for medial meniscal root repairs for a symptomatic acute and possibly a chronic medial meniscal root tear in a non-obese patient older than 40 years with a MRI that does not have early arthritic changes.
