August 19, 2013 :
A 63 year old lady was suffering from pain in the right knee for the last 15 yrs. She was almost bedridden for the last 4 years because of progressive deformity of her right leg. Her right knee was bowing outwards. As a result her knees were knocking against each other and her legs were now of different length. She was found to be having osteoarthritis of the right knee resulting in valgusdeformity. Majority (> 95%) of the patients have a varus deformity in which the leg bends inwards; only a few patients have valgus deformity in which the leg bends outwards. In this patient we could manage a good result using conventional implants. However, there are occasions when we have had to use special Constrained Condylar implants for the knee. She is doing very well in the recovery period.
