Grading of medial knee injuries is dependent on the amount of medial joint space gapping found upon valgus stress testing with the knee in 20° of flexion. Grade I injuries have no instability clinically and are associated with tenderness only, representing a mild sprain. Grade II injuries have broad tenderness over the medial knee and have ...
Sometimes they report weakness or decreased range of motion. The physician examines the knee in full extension, looking for tenderness in the medial knee joint and across the proximal, medial tibial region, and feels for tenderness along the medial tendons of the pes anserine when the knee is flexed at 90 degrees.

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 ...
Joint space narrowing, with or without subchondral sclerosis. Joint space narrowing is defined by this system as a joint space less than 3 mm, or less than half of the space in the other compartment, or less than half of the space of the homologous compartment of the other knee. II: Obliteration of the joint space III: Bone defect/loss < 5 mm IV
Localised tenderness over the medial knee is the most common finding of the condition. It is usually happening on one side, without a previous history of trauma. SONK should be considered together with differential diagnosis of osteoarthritis, tear of medial meniscus, and tibial plateau fracture. SONK usually has a sudden onset of knee pain ...
With the knee in 20° flexed, this angle should normally open laterally. [16] The patellofemoral index is the ratio between the thickness of the medial joint space and the lateral joint space (L). With the knee 20° flexed, it should measure 1.6 or less. [16]
The medial epicondyle of the femur is an epicondyle, a bony protrusion, located on the medial side of the femur at its distal end. Located above the medial condyle , it bears an elevation, the adductor tubercle , [ 1 ] which serves for the attachment of the superficial part, or "tendinous insertion", of the adductor magnus .

The knee bursae are the fluid-filled sacs and synovial pockets that surround and sometimes communicate with the knee joint cavity. The bursae are thin-walled, and filled with synovial fluid . They represent the weak point of the joint, but also provide enlargements to the joint space. [ 1 ]
