Knee surgical specialist

Every person's knee is different

"If you want your new knee to feel as good as possible and as close as possible to a normal knee, then you need a prosthesis that is going to match your size, shape and contours as accurately and reliably as possible.

This can only be achieved with a custom-made knee replacement, where the patient-specific prosthesis is designed and manufactured to be an exact match for the patient’s knee.

  • Custom-made knee replacements get best performance

    The Conformis iTotal custom-made knee replacement prosthesis performs well as the best implant on the market in terms of patient satisfaction rates. The latest Annual Report from The National Joint Registry also shows that the Conformis iTotal comes top as best knee prosthesis on the market in terms of how long it lasts.

  • ACL tears: get diagnosed QUICK!

    The ACL is common injured by footballers, skiers and netball players, particularly if one twists too hard on a bent knee: this then gives the classic ‘pop’ or ‘snap’ in the knee, normally with severe pain, and the knee gives way followed by the joint then swelling up significantly.

  • The benefits of 'customised' knee replacement surgery

    Knee replacement surgery is a big deal, and if you do actually need a knee replacement, then you want it done right, first time, and you want to ensure that you get the best possible outcome. Pick your surgeon carefully, and be fussy! Make sure that your surgeon gives you all of the information that you require to allow you to make the correct decision for what’s best for you, as an individual

A personal approach to expert care

Dear Mr McDermott,

It is now some 4 1/2 years since you replaced my right knee with a Conformis replacement. I have just returned from a very successful skiing trip and felt compelled to update you on the knee. 

My right and left knees feel identical in every way and frankly it is virtually impossible to tell which is the replacement. I can do everything that I would wish with my replacement knee, except some sports which I was aware would be off limits before the operation. The fact that I can still ski, cycle and walk with no real constraints is frankly astonishing. 

I can only thank you for the care that you provided and the result that has been achieved. I am immensely grateful.

Best wishes

Simon Carter

My knee now does aqua-aerobics two or three times a week, Pilates once a week, it walks normally and kneels down to plant flowers.

Dear Mr McDermott,

Just to say that my knee had its first birthday yesterday (and I have my 82nd birthday next month!).
At my first appointment you carefully showed me my scan results, explained to me my choices, took me through what would be involved in having the knee replacement surgery, and sent me papers to read. From that first appointment with you, I had complete trust in you. The evidence that you provided me about custom made knees persuaded me to go for that option, and thankfully it was covered by my BUPA insurance.
Prior to my surgery I had significant pain in my knee, I was only able to walk a quarter of a mile at most, I felt very nervous on my knee, with intermittent feelings like it might give way on me, and I had pain at night time.
It is now 1 year since I had my custom-made knee replacement surgery with you. My knee now does aqua-aerobics two or three times a week, Pilates once a week, it walks normally and kneels down to plant flowers. When stretching, I can just about bend it back up to my bum, like I do with the other knee. Sometimes it feels a bit stiff when I wake up, but I don’t have any pain at all now.

I am extremely glad that I had this done, so thank you again!
