Total knee Replacement - On the inside

I've a presentation on Total knee representation aka TKR this coming morning and since I only get to look at patients before and after surgery, I did some research and found this wonderful pictures to see what's on inside. It is really much more clearer than those shown in Trauma and Disease classes. :D

Almost half of the patients we would be dealing with are elderly that had went through TKR due to oesteoarithis in the knee. Immediate rehabilitation had to begin post-operation Day 1 by physiotherapists in order to ensure a good range of motion further on in life.

Surgical Procedure

Left knee incision during knee exposure and with knee extended (straight) shows wear behind patella (reflected backward on the right) and in trochlear femoral groove (in center of the photo).

Left knee: a cutting guide is prepared for removing damaged bone from the top of the tibia. The saw will be used through the slot near the top and front of the guide. The long guide with T-handle above goes down the length of the tibia to help establish satisfactory alignment for a precise cut.

Left knee in extension: the final prosthesis in place. The round white plastic disk is the back of the flipped patella, the silver component caps the lower end of the femur, and the white tray below the femur is the combined plastic-metal component on the upper end of the tibia. All components have been cemented with a very thin layer bone cement.
Left knee flexed: after complete resurfacing "total knee replacement". The wound is closed, and rehabilitation can begin.
