Custom Origin® Total Knee Replacement
Total knee replacement (TKR) involves replacing a damaged, worn or diseased knee with an artificial joint. It is a routine operation for knee pain most commonly caused by arthritis.
More than 70,000 knee replacements are carried out in England and Wales each year, and this procedure provides satisfactory results in terms of pain relief and mobility restoration.
Origin® Custom prosthesis with KNEE-PLAN® technology
Symbios has developed a proprietary pre- operative planning software system- KNEE-PLAN® . This technology uses CT scan images of your knee to create a 3D computer reconstruction. This allows a 3D simulation of your knee to be modelled to determine your native anatomy and its bony contours. From this information, a Custom or ‘bespoke’prosthesis (the brand name being Origin® ) is designed. The custom prosthesis is the same shape as your native knee and is optimally sized and contoured to create a prosthesis that feels as ‘natural’ as it possibly can, carefully reproducing the balance within the soft tissues that surround the knee joint. Following the design, 3D-printed customized surgical guides are manufactured. These assist the surgeon to accurately position the implants intra-operatively. This process is specific to each patient contributing to much improved outcomes following TKR.
- natural function
- natural kinematics
- reduced risk of post- operative prosthetic pain
- preserved bone stock
This Origin® Custom prosthesis is being introduced into the United Kingdom following release of the technology by the development group. This group, led by Dr Michel Bonin and Dr Ait Si Selmi at the Santy Orthopaedic Centre in Lyon, France, and Professor Carsten Tibesku in Straubing, Germany, presented their combined clinical experience at the Origin® pre-launch closed clinical conference in Lyon on the 22nd June 2018.
Why a Custom prosthesis
The Origin® Custom prosthesis was developed by Symbios to address patient dissatisfaction following TKR surgery. Peer reviewed literature suggests patient dissatisfaction can be as high as 20%, which is unacceptable in this day and age.
Furthermore, data from the National Joint Registry on Custom Total Knee Replacement (Custom TKR) shows a lower earlier revision rate of 0.5% at 4 years vs 1.9% for all other TKRs on the registry.
“Patient specific implants and instrumentation bring added value for the patient and surgeon alike. In my opinion, the precision and the 3-dimensional planning bring a real difference to the qualitative outcome following total hip and knee replacement surgery”.
