The Gloucestershire Knee Clinic are delighted to offer their patients state-of-the-art new robotic assisted knee replacement surgery at the Winfield Hospital in Gloucester.

Designed by surgeons for surgeons, the ROSA® Knee System provides objective soft tissue feedback and accurate bone resections, which aim to restore our patient’s natural knee.

Surgical precision

Getting a precise knee implant fit is important to your comfort and overall experience following knee replacement surgery.

Driven by data

ROSA Robotics uses data collected before your surgery and during your surgery to inform your surgeon of many details related to your unique anatomy that may affect your implant fit.

Informed decisions

By using this data to make more informed decisions, your surgeon is able to plan for and carry out a personalized surgery based upon your individual needs.



Safer Diagnostics

Less exposure to radiation

The Rosa System uses X-Ray over Computed Tomography (CT Scans) in pre-operative planning, leading to a reduced exposure to radiation for patients.

Increased Accuracy

Robotic-Assisted Precision

Numerous studies have demonstrated better accuracy of a new robotically-assisted system for total knee arthroplasty compared to conventional instrumentation.

Better Positioning

More natural feeling knee after surgery

Clinical outcomes have shown a more natural-feeling knee after surgery when using The Rosa System due to better implant positioning of robotic surgery.

Improved Outcomes

Higher patient satisfaction

Patient satisfaction outcomes after robotic arm-assisted total knee arthroplasty show higher long-term satisfaction when compared with conventional replacement.


The ROSA Knee robot is designed to help your specially trained surgeon tailor the placement of your knee implant just for you. Read more below about what makes the ROSA Knee robot unique, what to expect before surgery, what will happen during surgery and what to expect after your surgery.

Your experience before surgery will be like that of most total knee patients. But, unlike traditional knee replacement methods, The Rosa robot works in conjuntion with X-rays to create a 3D model of your knee anatomy and limb alignment. This 3D model will enable your surgeon to plan many specifics of your knee replacement prior to your surgery.

The surgical procedure using the ROSA Knee robot is similar to traditional total knee replacement, but with a robotic assistant. Your surgeon has been specially trained to use the ROSA Knee robot to personalize the surgical approach for your unique anatomy. It’s important to understand that the robot does not operate on its own. That means it does not move unless your surgeon prompts it to. Your surgeon is still in the operating room the entire time and is making all of the decisions throughout your surgery.

During your procedure, the ROSA Knee robot utilizes a camera and optical trackers that are attached to your leg to know exactly where your knee is in space. Think of it like a very detailed global positioning system (GPS) that you might use in your car. If your leg moves even a fraction of an inch, the robot can tell and adjusts accordingly. This helps ensure that the plan your surgeon put into place is executed as intended. Throughout your surgery, the ROSA Knee robot provides your surgeon with data about your knee. This information, combined with your surgeon’s skill, helps them know how to position your implant based on your unique anatomy.

Following surgery, you may return home the same day or remain in the hospital for one to three days, depending on the recovery plan your surgeon decides is best for you. Recovery time varies, but most people should be able to drive after two weeks, garden after three to four weeks and golf after six to eight weeks. Your surgeon will tell you when and what activities you can return to and what activities to avoid.

The above information is intended as a guide only. It is important to speak to a member of our surgical team before making the decision to proceed.
