Case study

In the Summer of 2011, dance teacher Yvette Levy had a high tibial osteotomy (HTO) operation. 

Using our School of Engineering's Motion Analysis Laboratory and the use of samples from her operation, we were able to help Yvette with her recovery.

"I ruptured my anterior cruciate ligament about 20 years ago which made my knee very unstable and caused arthritis. I was given the option of HTO or a total knee replacement (TKR).  As I work as a dance teacher I decided to go for the HTO. I had anterior cruciate ligament (ACL) reconstruction two years before the HTO which stabilised my knee and then the HTO to deal with the pain – which is now 200% better!"

"Before the operation, my pain was constantly at a level of six-to-seven out of ten. After I got up from sitting or lying down, the pain was too much to move around normally. It was absolutely worth it, the pain following the operation lessened after a couple of months."

"Because my weight distribution changed as they had altered the angle of my knee, it was a bit peculiar when I started walking, but I am used to it now – I was getting aching in my hip before the operation, but this has gone now too."
