Arthritic knee joints what type of either partially or totally - known as partial knee replacement and place total knee replacement. A partial knee replacement is also called as unicompartmental or "UNI". If for example the bone disease is restricted to the inner side belonging to the knee (the 'medial' side), a doctor will simply reshape those damaged surfaces. The repaired surfaces about this one side of what number of knee are then partially covered with a little metal and plastic bearings. Due to this situation, a UNI knee replacement has been said less invasive and offers much shorter recovery times in the event you operation.
The primary limitation through UNI procedure is the surgery only works for bone that has not been too damaged by the particular arthritis. It also requires that the other ('lateral') side of your knee joint have healthy and nutritious cartilage. The average age of UNI knee patients will therefore deemed a lot younger than those going for total knee replacement. This means that too as the UNI resurfacing option may only be helpful for a small percentage regarding knee patients.
Generally conversational, UNI knee replacements are not performed on patients with arthritic damage on both sides of the shoulder. In more arthritic legs, there will be exceptional erosion and deformity on both sides of the leg joint (as in 'medial' wife or husband 'lateral' sides). This will require more repair of top of the joint bone and the lower part joint bone and possibly also behind the calf cap. The UNI knee unable to accommodate such destructive changes in bone structure. Therefore if you do a surgeon will often opt to perform a total knee replacement , resurfacing bone with metallic cap and tray.
Note that the commonest method of fixing both implants to bone is with bone cement. There are also options to look after bony attachment and ingrowth directly into implants (bone ingrowth fixation). The last step is to put a plastic cover regarding metal tray to work as the bearing knee the knee joint.
There are other what to know. The majority of knee patients do not get their patella replaced evidently this may become an option further later on in life. There are also notions for knee operations that add smaller incisions (MIS: 'minimally invasive surgery') and use sorts of instrumentation such as computer-assisted gps device (NAV).
Your doctor should explain to you which type of Knee Replacement Surgery is best for you and why.
