The surgeon must set the correct position for placing the artificial joint surface. Adjusts the tightness or looseness of the tissue surrounding the knee joint appropriately. Currently, the shape of the artificial knee can be bent approximately 100 -145 degrees.

The material of the artificial knee surface is made from metal and polymer. It is solid and safe for the body and meets international certification standards from the United States (FDA); the artificial knee surface is attached to the bone with cement (Bone cement) to increase the adhesion strength between the metal joint surface and the bone.

Behavior after knee replacement surgery
After surgery, patients can immediately sit up and move their legs and ankles. When you feel awake after surgery, practice walking within 24 hours with physical therapy. The patient should be able to bend the knee to at least 90 degrees and extend it to almost full extension; then, you can return to your home for further treatment.
