Statistics….Statistics

Close examination of the data from performing around 300 osteotomies has thrown up some very interesting information covering all aspects of the operation.

One of the most revealing insights is a change in the general profile of the ideal patients who have undergone the operation. With the data we now have we are able to challenge previously held concepts an convictions and make a case for opening up the procedure to a wider audience.

Originally we surgeons thought the age of the ideal candidate for the procedure was someone between aged 40 and 55. But now we know in certain cases older patients have the capability of doing just as well, if not better after the operation provided they meet the right criteria.

As people get older their knees tend deteriorate in all departments, but if you have someone who is 70, very active and only has a problem in one area of the knee an osteotomy be a great operation for them.

And as well as age we have also altered our attitude towards the body weight of patients as to whether they are suitable for an osteotomy.

Average Body Mass Index (BMI) ranges between 25 and 35, but we have now operated on a few patients with a BMI as high 40. They responded really well and been very happy with the surgery and we are delighted that the supporting plates we have used have been strong enough to cope with patients who significantly overweight.

The data has also shown that, how by using the Osteotomy procedure, we can also change the dynamics of the knee. An area which can prove to be particularly valuable is to alter the slope of the fibula. Occasionally in very specific cases where we get a patient with ruptured ligaments we alter this slope to make the knee more stable.

The observations above outline what help data can be to us and with that in mind here at North Hants we should soon have even more information at our fingertips.

A new addition to our team is David Elston and he is establishing a national register which will collate and examine the work of every Osteotomy group in the UK.

It’s by looking at what we have done that enables us to plot the future.

Statistical analysis broadens the patient pool who can benefit from Oseotomy.

The combined experiences of Osteotomy groups around the country are changing the criteria for the selection of patients who can benefit from the relief that an Osteotomy can provide. Read our blog to find out how.
