London Private Hospital For Total Knee Arthroplasty: AI-Enhanced TWIS-TKR

May 14, 2024

Knee surgery isn’t what it used to be, in fact, it’s better than ever. MSK Doctors uses a unique new program called TWIS to provide highly customised results for a total knee replacement, by using advanced AI motion analysis to help plan the surgery.

You may not believe this, but I recently had a knee surgery myself, and I had two amazing doctors working on them, at the same time.... They told me it was a joint operation.

Ba-dum-tiss. Seriously though folks, I'll be here all week, don't forget to tip your waiter, and you can find all the information you ever wanted to know about total knee replacement surgery at

If you'd rather stick around here, and get the details from me first - that's great, because I've got a lot more information about advanced knee replacement options, and a few more jokes.

I think the doctor might have accidentally installed a new funny bone!

Beyond The Bee's Knees

We've all heard the saying, the common wisdom is that bees have the best knees    •but do you know what? I checked, they're way too small, and they would never fit me, so I want to tell you about the next best thing instead.

It's called TWIS-TKR... which is a long way of saying Turn With Intelligent Stability - Total Knee Replacement, and incredibly long name aside, it's a super cool technique. Cooler than anything the bees can do, for sure.

What makes it different, primarily, is one simple change to the surgical process - a custom rotational alignment you won't find with any traditional knee surgery.

Let's cover how it works, what the process is, and what people think of it, in that order.

How It Works, Explained Simply

Let's be clear here, I'm not a doctor or a surgeon, so I'm going to explain things in simple, easy terms, and if you want the technical details - you can click right here to get them, straight from the experts.

The short version is simple - with traditional knee surgery, it's a "one-size-fits-all" type of procedure, but we all know that our bodies don't work like that.

This new technique takes a more realistic approach by finding how you move, and then planning your new knee to match. There's some AI involved, but just in the planning process, don't worry - and we'll talk about that next.

The Process, What You Need To Know

There is actually less to tell you about in the process than you might expect, because 90% of it is the same as a traditional surgery.

Where it differs is in the planning stages, and the results - at least as far as we're concerned.

It all starts with MAI Motion, a partner of MSK Doctors that helps to collect all the data they need about your knees, how they move, and how they interact with your body during a wide range of different natural motions.

Another way to say that is, they'll ask you to perform a bunch of motions and movements, climb these stairs, walk over there, bend, squat, crouch, jump, anything you can - while the AI watches. Then it will take all that information about exactly how you move, and provide it to the surgical planning team, so they can customise your prosthetic implantation.

What Matters Most - The Results

We've made it, we're finally there, ready to talk about what matters.

During the process, the extra appointment or two might be a bit of a pain, all the extra testing could be uncomfortable - but does any of that really matter in the long run? Probably not.

A year later, you're not going to care about an extra visit to get a better fit for your prosthetic, unless you're regretting not doing it. The tiny bit of extra work is entirely worth it, because the results are... well, I'll let them speak for themselves.

Here are a few facts I've collected from various clinical trials on the TWIS-TKR technique.

Researchers believe that this system helps to better balance loads and stresses on your knees, which can reduce wear and tear. That means your prosthetic should last longer than ever, and there's less risk of needing a second surgery.

Patients with a TWIS knee are known to recover faster, and return sooner to their normal activities, like climbing stairs, and walking normally.

With a custom rotational alignment, most folks self-report a whole range of improvements, including a better range of motion, a more natural-feeling joint, and less overall pain or discomfort.

Overall, individuals with a TWIS-TKR prosthetic report a higher quality of life, because everything just feels and works... naturally. What more do you want?

Fast access to top surgeons and specialists for consultation, diagnosis, or even treatment, with no referral from your GP, and no waiting list?
