On the 9th January, The London Clinic consultant Mr Dinesh Nathwani successfully performed the world’s first BioPoly partial knee resurfacing procedure. The surgery was conducted through The Advanced Therapies Centre, a newly launched clinical trials facility at The London Clinic, which aims to provide innovative treatment choices for patients through access to trials and novel therapies. BioPoly knee surgery, which enables the patient to immediately weight bear (with the aid of anti-inflammatories), uses a new type of material combining hyaluronic acid and ultra-high molecular weight polyethylene. When combined, these two materials improve the wear qualities of the prosthesis, whilst also providing a biologically lubricated surface that effectively interacts with the body’s natural tissues. The material is strong enough to take the weight of the body, but also has a degree of flexibility not matched by standard metal replacements.
The procedure is bone conserving, meaning that only the damaged cartilage is removed. The prosthesis is then attached to the end of the bone via a metal stud anchoring it into place. By preserving the healthy bone and cartilage, younger patients experiencing knee problems and who are likely to need further reconstructive work, will have as much healthy bone in-tact as possible, making future operations not only viable, but less complicated. Patients who will benefit from the BioPoly procedure are those presenting with painful cartilage lesions of the femoral condyle, who might not be suitable candidates for other procedures including biological treatments or joint replacement.
Mary Keal, the first person to receive the BioPoly prosthesis says “My experience of BioPoly so far has been excellent. I was in pain when crossing my legs or walking up stairs; anything where my knee was at an angle. Since my operation, this pain has completely disappeared. I was able to weight bear straight away with the aid of crutches, after 4 weeks I was cycling again, and at 7 weeks I am increasing the resistance.”
Mr Dinesh Nathwani, the Surgeon who performed the operation comments “I am exceptionally pleased with Mary’s progress. The bone conserving nature of the procedure, along with the new BioPoly material used means that recovery has been relatively quick and the original pain experienced has disappeared.”
The London Clinic is one of the four UK centres that are involved in this multi- centre registry trial which has been fully approved by the UK multi regional ethics committee and data collection and analysis of this study is on-going. The London Clinic is committed to utilising its state of the art facilities and world leading expertise, in order to provide patients with access to novel therapies, procedures and the best possible care options.
Ground Ambulance Transport Companies come in different shapes and sizes and you must ensure you source a ground ambulance company with superior service and no hidden costs. Some Ground ambulance companies do have hidden fees and it is important to read the small print when sourcing a ground ambulance provider.
