Structures to Review. - PowerPoint PPT Presentation TRANSCRIPT. However it should be realized that a replaced knee may look like a normal knee on the outside but in fact it is very different from the normal knee. The aim of this short report is to examine knee joint anatomy and physiology with respect to knee stability. Surgeons performing reconstructions in patients with these injuries must have a complete understanding of the normal anatomy and biomechanics of the knee to optimize the timing of surgery, the order of ligamentous reconstruction, and the anatomic placement of grafts. Clipping is a handy way to collect important slides you want to go back to later. This ingress involves implanting tantalum landmarks in the osseous tissue and then capturing roentgenogram. But most weakest srture of it is its neck. It shortens and extends lower limb as required and transmits forces across it. Knee Muscles.
