Knee Replacement Surgery

Knee Replacement has improved dramatically over the last 3 years with further advances in the last 3 months.

Traditional total knee replacement was asscoaited with satisfaction rates of 80% but now these are 95% with quicker and easier recoveries for most patients.

Custom Knee Replacement / Resurfacing 

Knee Replacement / Resurfacing, Attune (non-custom)


Ethos: To provide the very best in service, experience and outcome.

National Specialist in Custom Knee Replacement, including total knee and partial knee replacement.

Why choose James Lewis?
In short I am driven to continually improve every aspect of the knee replacement experience and outcome. The small details added together make a real difference, I am continually amazed at the improvements in early outcomes, this is great for patients - such as the lovely chap last week who cycled two miles to see me for his two week follow-up check and then cycled home again.
The details are in preoperative preperation risk reduction, surgical precision and judgement and a close knit, excellent, stable theatre team. Members include assistant anaestetist, scrub staff, anaesthetic assistant.
After care is also extrememly important with hand picked physiotherapist, hydrotherapy, pain prevention and sleep protocol and the amazing Gameready device 
The surgery itself is carried out without use of tourniquet where possible to reduce pain and swelling and therefore aid early recovery. 
Implant postionioning with developed techniques for reproducability. Technical areas at surgery including low impact cementing and fixation technique to reduce hammer induced bone trauma and accurately reproduce cement thickness to within 1mm of designers recommendations. 
I am obsessive regarding infection prevention approach including infection restistant stitches with increasing specialisation, critical assessment, team work. I have made and perhaps pioneered a number of advances which translate in to reprocucabiliity and predictability of outcome. I use specialist additional intstruments, some custom made for a particular stage of the operation, I am privaledged to train and share experiences with other consultant surgeons on a one to one basis and both present at and attend national knee replacement meetings.
Most Custom knee replacement patients go home the day following surgery, most Attune knee replacement patients go home after 2 nights.
My aim is provide a first class outcome for those with painful knee arthritis seeking:
  • a rapid recovery with as much comfort and minimal swelling as possible,
  • restoration of quality of life,
  • a new knee that feels like one's own,
  • trust and stability in thier knee
  • strength
  • return to an active and enjoyable lifestyle
  • focus on risk reduction including avoidance of transfusion and and an exceptionally low infection risk.

Which is the Best Knee Replacement?

The focus of knee replacement has been on how long they last rather than how they "drive" or perform.

In my view the Conformis iTotal is the best performing Knee Replacement. It has taken me over three years to be sure of this view and a number of technical operational refinements to deliver reproducability to reach this conclusion. I have formed this view from studies, presentations, and personal experience. The Custom iTotal is a little more expensive (£13900 plus CT scan) but does well in the following areas of: 

knee feeling like one's own natural knee, 

strength and power in the knee, 

straight leg alignment,  

trust in the knee,

flexion (bend in the knee), 

low incidince of clicking,

near natural movement, 

forgetting about one's new knee

return to activities

material quality and thus wear expections and predictions

overall satisfaction.

and finally documented side by side patient diaried recovery experiences are startling (standard knee of the 2000s on one side and a Conformis on the other)

Apart from cost and a manufacture time of 6 weeks I am not aware of any downsides when properly implanted. I think the tolerances of implantation with the Conformis are potentially narrower than some other implants. A possible limitation is that it has been available for 10 years, it is true that some older knees have been available for longer and thus have a longer follow op time period. Overall I would rate it as 9.8 / 10. I have fed back suggested refinements to Conformis the manufacturer on instruemtation and planning areas rather than the implant itself. 

I have 16 years of consulant knee replacement experience and have used different brands and different designs with varying philosophies of design. In the 1990s and 2000s the outcome of knee replacement across the continents was an 80% patient safisfaction rate with the dissatisfaction commonly being in areas of pain, tightness, poor bend and limitations of activities. Of the designs in this era the data or "expert review" that compares outcome of one knee prosthesis to another is remarkably lacking. In most products such as cars or cameras there are several sources of review. I suspect the reason is partly that surgeons tend to stick with one design of knee replacement and partly the barriers of carrying out a comparative study of two types or brands. The strongest data indicates that in the 2000s that the NexGen was the best knee replacement when comparing the four leading brands althought the differences were small between the NexGen and the others. Some comparative data indicates that a medial pivot design of knee is better than other designs. In the 2010s decade there have been new designs from many implant companies. One company DePuy Syntheses has launched the Attune Knee which has 4 year Data in the national Joint Registry. Other new designs are the Persona from ZimmerBiomet, XP Preserving knee from ZimmerBiomet, Journey 2 from Smith and Nephew and Saiph Knee from Mat Ortho. There will be other knee replacements of new design but none that I have been aware of significant clinical use in the UK to include in comparions. I have searched (10.06.17) the PubMed database for outcomes with these new knee implants and can find very little to demonstate the quite probable postive outcomes of the other new knee brands. The Persona data shows better outomes with the more congruent polyethylene insert than the less congruent insert. I have  examined and interviewed a small number of  selected XP preserving patients by lead surgeons at an international meeting and formed the view that they were less good than the Conformis in the areas of feeling like a normal knee and stability. 

Returning to new vs old knee designs. The Attune performs better in every domain of patient function, performance and satisfaction than the Depuy Knee of the 2000s namely the PFC, using this comparator if the PFC was similar to the other knees of the 2000s, which it was acording to patient reported outcomes, then logical follows that it is better than the other knees of this period. However the Attune does not have long term results (3 years of at least a hundred patients). Comparative data or experience of other knees versus the Attune are lacking. Movement based studies of the implant design favours Conformis over Attune. My experience of Conformis and Attune favours Conformis in the areas of power, stability, trust and reduction in clicking. Conformis wins on power through its trochlea referencing at the front of the knee and rotational matching which reduces clicking. It also comes with pre navigated positioning guides called PSI or patient specific instruments which help the surgeon place the implant in the right place. Finally it has a better fit on the top of the shin bone (tibia)

I would probably rate the  Attune as 9.5/10 for early outcome

Other modern knee designs / Brands are probly in region of 9.5/10. Some evidence would favour the medial pivot knee (Saiph) and from my own personal assessment of the XP in expert hands I don't think the upsides warrant the downsides.

I would rate Knee replacements of 1990s and 2000s  as a whole as 8/10 based on satisfaction rates of 80%, there may well be exeptions.

How much does it cost to have a knee replament? (all inclusive Package)

Attune Knee Replacement  £12 315

Custom Total Knee Replacement £13900 plus scan

I use the Attune Knee Replacement and the Custom iTotal Knee Replacement.

Experience: I have carried out 750 knee replacement or knee resurfacing proceedures over the last 3 years, which places me in the top 15 in England and Wales and the in the top 2 for Conformis custom knee replacement.

The Attune and Conformis give proven superior outcomes in a number of measurable areas including patient satifaction. One study shows an improvement of patient satisfaction from 74% to 94% with the Conformis knee compared to a traditional knee.

Please see the rationale for Custom Knee Replacement.

Hip Resurfacing: Patient feedback Febuary 2015:

After many years of high-end sporting activity - covering a mix of Judo, Olympic weight-lifting an Tae Kwon Do - my right hip began complaining that perhaps I'd written a few cheques in my youth that it now wished to cash in!! Initial thoughts were centred around back-problems, as post training, I would suffer severe back ache on my right side and pain in my groin leading to sleepless, or at best, disturbed nights. Eventually, after many visits to the chiropractor, I saw my GP who referred me to Mr. James Lewis at Goring Hall. Initial X-Rays indicated OA. Options were discussed including the possible use of BHR, which on-balance sounded like the best option moving forward. 

Being an engineer by background, and having a daughter with a background in sport science, I embarked upon researching this form of intervention from both perspectives. It very quickly became apparent that there were a number of athletes who had also elected for BHR and who had returned to their original activities; some even returning to competition. 

My research also indicated a number of key criteria that should be considered when embarking on a BHR: 

1. Select your surgeon carefully: Whilst experience is a factor, other aspect are equally important such as attention to detail, meticulous planning, ability to communicate and build a strong patient / consultant relationship with an empathetic stance towards sporting activities. 
2. Ask many questions: Including topics such as past patient experiences (both good and importantly not so good), prosthetics used and their characteristics in terms of manufacturer; how they rank in terms of performance; metallurgy and even (if you can bear it - there are some very good YouTube videos of the procedure out there!) info on installation procedure.
3. Recovery protocols: For active, sporty people I would countenance that this is fundamental. Mr Lewis and his team focus specifically on this area. This is apparent from the get-go with not just an array of good information pamphlets made available, but with a recovery regime targeted towards resumption of mobility as quickly as possible. This starts subtly with small aspects such as the use of carbohydrate loading as part of the pre-op regime to combat muscle atrophy, on to the option of anaesthetic used for the procedure with the advantages present with respect speed of recovery if a spinal and sedation option is selected. On this last point, I was initially sceptical, never having experienced this process before. But I can now vouch for its effectiveness and advantages. 

James Lewis, in partnership with all of the excellent staff at Goring Hall, has built a team around him that appreciates these aspects fully and do all they can to ensure a rapid return to mobility, and in time, sporting activities. 

Overall, for the younger active patient presenting with similar issues who wish to maintain their QoL, including sporting pursuits, the BHR solution under James Lewis' holistic approach  is a solid option well worthy of consideration.

National Hip resurfacing outcomes with the Birmingham resurfacing product as per the NJR (National Joint Registry)

Data current as of Feb 2015 - the NJR 11th edition published in 2014.

9% of Birmingham resurfacings have been revised (redone) at 10 years. This data set is of patients aged at a median of 55.

This is at least as good as total hip replacements in those of similar age:

10.5% (in the under 55s) or 8.5% (in age 55 to 59) of total hip replacements have been revised at 10 years (NJR data).

Of the resurfacing Brands, the Birmingham is the most favourable (LINK) data on page 50.
