In a 40 minute surgery performed at the Spire Hospital in Cardiff, Dr. Rhidian Morgan Jones fitted a specially designed slim line knee called as the Zimmer Knee. The cost of the surgery was about £10,000.
During the investigation prior to the surgery, Dr Rhidian found that that the cartilage in Helena's knee was practically eaten up. There was no way out other than a replacement. He advised her to go in for a specially designed women's knee replacement.
Post operation, Helena is back on her feet and is doing well with the assistance of physiotherapy.
Talking about the novel Zimmer knee, an adapted knee replacement to suit the female body, Dr. Rhidian said, "It is specially contoured, smaller overall with a slightly different shape and angle for the fitting. The standard knee replacement which is fitted to both men and women is still fine for a vast majority of patients but the new knee is more suitable for women who may be taller, smaller or thinner than the average. It is a very good option for the right women and more comfortable."
