Hip-knee-ankle angle. On projectional radiography, the degree of varus or valgus deformity can be quantified by the hip-knee-ankle angle, [7] which is an angle between the femoral mechanical axis and the center of the ankle joint. [8] It is normally between 1.0° and 1.5° of varus in adults. [9] Normal ranges are different in children. [10]
English: Postoperative X-ray of normal knee prosthesis of a 73 year old man who had osteoarthritis. Anteroposterior view. It shows the following measurements used for post-operative evaluation: FFC: frontal femoral component angle. It is typically regarded as optimal when being 2–7° in valgus.
Projectional radiography, also known as conventional radiography, [1] is a form of radiography and medical imaging that produces two-dimensional images by X-ray radiation.The image acquisition is generally performed by radiographers, and the images are often examined by radiologists.
Dial Test (posterolateral rotation test) - The dial test can be performed with a patient lying supine or prone. With the patient supine and the knees flexed 30° off the table, stabilize the thigh and externally rotate the foot. As the foot rotates, watch for external rotation of the tibial tubercle of the affected knee compared to the healthy ...
