Besides this, the decision taken by the surgeon to make use of one surgical procedure over the other or an implant type over the other, it will depend mainly upon the clinical situation and the surgeon’s training. As a matter of fact, every implant design comes with its own advantages and disadvantages. Irrespective of the type of implant the surgeon decides to use, it will be better to know total knee replacement treatment offers greater success rates among all orthopedic operations.

Knee replacement surgery – What happens?
Arthritis of the knee modern treatments is taken care of by the experienced surgeons. The knee’s damaged bearing surfaces are replaced by the total knee replacement, which could be the cause of extreme pain. The femur’s (thigh bone) lower end, the bone gets trimmed towards accepting special shaped metal component. On the other hand, the tibia (shin bone) upper end is trimmed towards accepting the metal tray, in which is fitted plastic bearing.
Metal components are then secured for cutting the bone surface using choice of bone non-cement or cement type known as ‘bone ingrowth’. Most knee replacements are cemented into place. Besides asking the question ‘Whatis the best total knee replacement’, the patient should also discus with the surgeon on what fixation type will be used for holding the knee in its place.
The femoral component’s outer surface has been designed to allow patella (knee cap) to slide down and up in its groove. The natural kneecap can be either retained or resurfaced as deemed fit by the surgeon. It is also a question that is to be discussed with the surgeon.

It means the polyethylene that is inserted is mobile (can move on rotating metal base) or fixed (clicked onto stationary platform). The latter is preferred by majority of the patients as it helps to reduce significantly knee pain and is also found to be durable.
