Virtual Knee Clinic

We are working on setting up a "virtual knee clinic" which will allow us to deal with numerous email and telephone enquiries, which are increasingly difficult to manage. Most of the time we are unable to offer a proper "online" consultation, either because we do not have enough clinical information before we see and examine the patient in one of our clinics, or because of numerous percieved regulatory and data protection issues. We do believe that a lot of information and clinical advice that we may be able to offer can and should be provided by email and telephone, especially in cases where it is not essential to attend a classical face-to-face consultation (exchange of preliminary clinical information, follow-up appointments, minor postoperative problems, etc.). Therefore, we are planning to open a Virtual Knee Clinic, which will have protected time one day a week. We just need to complete our discussions with the GMC, MDU and Data Protection Office and find a way how to invoice for our services. Work in progress, watch this space ...

OrthoBiologics: Adipose Tissue Derived Autologous Stem Cells

Since January 2015 we have Chester Nuffield's MAC approval for surgical use of Adipose tissue Stromal Vascular Fraction (Adipose SVF). There is a worldwide consensus that regenerative cells from differentiated autologous body tissues are the most ethical option in regenerative medicine. The general preference for Adipose SVF is based on easy clinical harvest of adipose cells and a huge regenerative cell density (10 to 100 fold more stem cells than other body tissues). We are planning to use this technology as an addition to several standard orthopaedic procedures like autologous osteochondral grafting, subchondral decompression, osteochondral repair and similar. We are comparing different technologies and preparing technical side of introducing this technology to our clinical practice in the summer of 2016.

Lamina Splendens Research

The uppermost layer of hyaline articular cartilage is called Lamina Splendens. This film-like layer is seldom seen arthroscopically and various optical and electron microscopic imaging studies have shown conflicting morphology and structure. Considering its location there is no doubt that Lamina Splendens has extremely important articular function as it provides a very low friction lubrication surface and contains collagen fibrils which run parallel to the surface of articulation. This surface zone layer is likely to play a key role in maintaining the mechanical response of articular cartilage to load. It is the first region of cartilage to degrade in ostroarthritis and yet there is no evidence that it is regenerated when articular cartilage is repaired, not even with autologous chondrocytes. This is a significant limitation that, unless resolved, may lead to the ultimate failure of any articular cartilage implant as a result of the shear forces in the joint. For this reason, it is critical to understand the role of the surface zone of cartilage in development, joint function, and pathology.

As the structure and function of this elusive articular layer remains unclear, we have started collaborative imaging project on morphologic and structural imaging and functional research of animal and human lamina splendens at the Institute of Integrative Biology at the University of Liverpool, UK (Prof Anthony Hollander) and Osaka Health Science University, Japan (Prof Norimasa Nakamura). This project and our preliminary findings were presented at 12th ICRS Congress in Chicago in May 2015 and we will present an updateat the 13th ICRS meeting in Sorrento in September 2016.

BioPoly™ RS Partial Resurfacing Knee Implant Clinical Trial

This clinical trial is now complete and closed. We have presented preliminary results at several national and international conferences in 2015 and will publish a paper towards the end of 2016.

This technology is now readily available and we are happy to offer this surgical procedure (partial femoral condylar resurfacing) to our private patients. BioPoly implants are also available to NHS patients at Aintree Hospital Liverpool, the Imperial College London and RNOH Stanmore, and several other hospitals in the UK.

BioPoly Partal Resurfacing Implant is indicated for patients who present with a painful articular cartilage lesion of the femoral condyle and who is not a candidate for biological treatment (articular cartilage repair) or total joint replacement.

The BioPoly™ first implantation was done early in January 2012 by Mr Dinesh Nathwani at the London Clinic (for more information please see the article from The Telegraph and the article from Mail Online). The first large BioPoly (the "racetrack") was implanted in April 2012 by Mr Mike McNicholas, at the Warrington Hospital. So far we have implanted 32 BioPoly implants, with good short to mid term functional results.

BioPoly® Announces 100th Knee Surgery (14 April 2015): Herb Schwartz PhD, President of BioPoly, stated “We are very excited to reach this important milestone. With the longest term patients beyond the 3 year time point, the implants are performing remarkably. Patients can bear weight immediately after surgery and return to normal activities within weeks. They are reporting that they are pain free and are showing marked improvements in their quality of life.”

Pinterest Arthroscopic and MRI Image Boards

We are posting a selection of original arthroscopic and MR images from our daily clinical and surgical practice on Pinterest and Twitter. All images are anonymous and are intended to provide good quality visual information on typical knee problems but also normal knee anatomy for educational purposes. We will aim to Tweet a few selected images from time to time but all images will be available on Pinterest Arthroscopy and MRI boards. We are still thinking about posting some images on Instagram. Please let us know your thoughts (


We went back to Kaunertal, Pitztal, Mayrhofen, Hintertux, Stubai and explored Solden (which was great) in December 2015 and January 2016. We expected poor snow conditions at low altidudes and made an effort to chase good snow on several glaciers, above 3000m, which was a good tactic as always (except Hintertux which was quite icy and unusually did not have much snow even on top). We also skied in Are, Sweden, in March, during the ACL SG meeting, which was good apart from one rainy and one very windy day. The best skiing was in April and we went back to Kaunertal for a day (which was, as always, excellent) and a week between two glaciers in Solden which was also excellent - early spring high-altitude skiing never fails: good snow (we had a few days of new powder), long sunny days, no crowds. Magic!
