The knee remains the joint most susceptible to wear and tear and many of us suffer from degenerative knee conditions, such as osteoarthritis, that can cause us much discomfort and result in a lack of mobility that affects us on a daily basis.

The first steps are usually to try and control the pain and increase functionality using non-surgical methods, but when these treatments fail to provide relief, then knee replacement surgery is often the most appropriate option.

The National Joint Registry records over 80,000 knee replacements are performed in the UK every year and that number is steadily increasing, particularly as we have younger and younger patients seeking a surgical solution to joint pain and lack of mobility.

Knee replacement surgery, also known as arthroplasty surgery, is a long-established and typically very successful procedure, but satisfaction rates for Total Knee Arthroplasty (TKA) surgery are known to be lower than those recorded for hip replacement surgery and inaccuracies in implant positioning and soft tissue balance can impact patient outcome. For this reason, orthopaedic surgeons and medical technology companies are continually striving to develop techniques and tools that improve accuracy and deliver higher patient satisfaction.

Therefore, Mr Simon Bridle is delighted to be one of the first knee surgeons in the UK to employ Stryker’s Mako Robotic Arm-Assisted Surgery in knee replacement procedures.

What happens during knee replacement surgery?

During a Total Knee Arthroplasty, Mr Simon Bridle will remove any damaged cartilage and bone and then then position the new synthetic implants to restore the alignment and function of your knee.

What happens during a Stryker Mako Robotic-Arm Assisted Knee Replacement?

Robotic-Arm Assisted Surgery does not take the place of the surgeon, but instead allows them to offer a more accurate surgical procedure. Each procedure can be meticulously planned and a 3D model based on the patient’s specific diagnosis and anatomy is produced prior to surgery.

First, a CT scan is taken of the patient’s joint, which generates a 3D model of your unique anatomy. This is then loaded into the Mako software and a preoperative plan is produced, focusing on the implant’s position and choosing the ideal-sized implant to reproduce the patient’s own anatomy.

Adjustments can then be made by the surgeon during the surgery to achieve the best implant alignment, soft tissue balancing, and flexion for each individual patient.  The bone cuts are then made using the robotic arm, within haptic boundaries (this means that the tools are not allowed outside a defined window) and this avoids unnecessary damage to soft tissues.  Very accurate cuts are achieved and this means that positioning of the knee implant is far more accurate and reliable, giving the best chance of achieving a good result.

Since the Mako total knee replacement application was launched in mid-2016 there have been a number of clinical studies performed that have found that soft tissue damage, early pain and blood loss were all reduced compared to manual TKA surgery and multiple studies have found that the early outcome from surgery is highly positive, with patients reporting high levels of satisfaction and an improved functional result.  Patients seem to feel that the knee just feels more normal.

MAKO assisted knee replacement is now available at the BUPA Cromwell Hospital and Parkside Hospital in Wimbledon.   The whole surgical pathway is defined by an Enhanced Recovery Programme. Patients are seen by the team before the surgery.  At BUPA Cromwell this includes a ‘Joint School’ run by the physiotherapists, to best prepare you for surgery.  After surgery, Mr Simon Bridle and his team closely supervise your progress, with a rehabilitation plan suitable for your individual needs. At Bupa Cromwell there is a Fortius Physician, who is available to deal with any unexpected medical problems and help look after more complex patients.
