With the increase in the longevity and demands of the patients’ hip and knee replacement surgeries are tremendously on the rise. In India when compared to the western countries, degenerative arthritis of the knee joint is at least 10 times more common than the western population. And hence it is not uncommon to see people more than the age of 60 years to have a bow-legged deformity. The older concept of retaining their own joints and tolerating pain, deformity and restricting their lifestyle and social activities is slowly mitigating away. The Indian population is emerging out of its taboos and myths.
Currently almost all joints of the body, including the small joint of the fingers can be replaced by well engineered and follow up documented prosthesis.
Due to the import of the prosthesis the price of them is placed slightly on the higher side. Of late Indian companies have started manufacturing these prosthesis so that the patients will be benefitted at more subsidized costs.
The more common deformity of the knee joint is the bow-legged deformity (VARUS). The less common is valgus deformity. Whatsoever is the amount of angular deformity the knee joint can be very precisely corrected to its original anatomical dimensions. In case if there is any bone loss it can be managed bone grafting procedure. If the ligaments around the knee joint are unstable a constrained type of prosthesis can be implanted. In case if the primary surgery fails either due to excessive wear and tear or due to periprosthestic fracture, a revision total knee replacement with long stemmed prosthesis. Recently high flexion knee have been introduced to provide maximum flexion of the knee joint so that sitting in the figure of O manner is possible.
