Many studies have demonstrated higher precision and better radiological results in Total Knee Replacement (Arthroplasty) with computer-assisted surgery (CAS). On the other hand, studies revealed a lengthening of operation time up to 20 minutes for this technique and demonstrated rare additional complications as fractures and neurovascular injuries caused by the array pins and any intraoperative array dislocation leads to abortion of CAS.
Joint replacement aims to restore painless motion to a joint and function to the muscles, ligaments, and other soft tissues that control the joint. Either a part or the total damaged bone is removed and replaced with artificial components made out of metal and polyethylene and the bones of the joint are "realigned" so that the weight that passes through the joint is normally distributed. Hip and knee the major weight bearing joints are the most commonly affected joints and are commonly replaced. Ankles, shoulders, elbows, wrists and fingers can also be replaced.
Joint replacement relieves pain, restores function and the newer type of joints allows unrestricted activities.
Previously it was recommended for patients more than 60 years but now it is being more and more recommended for younger patients.
