Lateral view. It shows the following measurements used for post-operative evaluation : Anterior femoral notching (the femoral component causing reduced thickness of the distal femur anteriorly), which seems to cause an increased risk of fractures when exceeding about 3 mm. Reference:

A knee dislocation is an injury in which there is disruption of the knee joint between the tibia and the femur. [3] [4] Symptoms include pain and instability of the knee. [2] Complications may include injury to an artery, most commonly the popliteal artery behind the knee, or compartment syndrome. [3] [4] [7]
A difference of greater than 10-15° indicates a positive test and likely injuries to the posterolateral knee. Next, repeat the test with the patient's knees flexed at 90°. Increased rotation at 90° indicates a combined PCL and posterolateral knee injury. If the rotation decreases compared to 30°, then an isolated PLC injury has occurred.

Deep lateral femoral notch sign Measurement technique to determine the depth of the femoral notch on lateral x-rays. In radiology, the deep lateral femoral notch sign is a finding on a lateral radiograph that is considered an indirect sign of a torn anterior cruciate ligament (ACL). [1] [2] It is an abnormal deepening of the lateral ...
To indicate knee replacement in case of osteoarthritis, its radiographic classification and severity of symptoms both should be substantial. Such radiography should consist of weightbearing X-rays of both knees: AP, lateral, and 30 degrees of flexion. AP and lateral views may not show joint space narrowing, but the 30-degree flexion view is ...
