Robotic Total Knee Arthroplasty
ROSA® Knee System: Innovative Robotic Assistance for Total Knee Arthroplasty
The ROSA® Knee System, developed by Zimmer Biomet, represents a significant advancement in the field of orthopedic surgery, providing surgeons with a robotic assistant that enhances accuracy and the level of care in knee replacement procedures. This state-of-the-art system utilizes real-time data to assist surgeons in precisely placing implants during total knee arthroplasty, tailored to each patient’s unique anatomy.
Indications for Robotic Total Knee Arthroplasty with the ROSA® System
The ROSA® Knee robotic system is intended for individuals with early to mid-stage knee osteoarthritis. Osteoarthritis is a degenerative joint disease characterized by the breakdown and eventual loss of cartilage, ultimately leading to bone-on-bone contact. Symptoms include knee joint pain, swelling, and reduced range of motion, significantly affecting daily activities. The ROSA® system is especially beneficial for patients who do not respond to conservative treatments such as medication, physiotherapy, and lifestyle modifications.

Preparation for Robotic Total Knee Arthroplasty with the ROSA® System
Preparation for surgery with the ROSA® system involves several steps similar to traditional total knee arthroplasty procedures. However, one key difference is the use of advanced imaging technology. Specifically, before surgery, a series of X-rays is taken to create detailed three-dimensional images of the patient’s knee. These images allow the surgeon to design a personalized surgical plan that takes into account the patient’s specific anatomical features. This individualized approach ensures that the surgery is tailored to achieve the best possible outcome.
Procedure of Robotic Total Knee Arthroplasty with the ROSA® System
The surgical procedure with the ROSA® system is similar to traditional techniques for total knee arthroplasty but includes robotic assistance. It is important to note that the ROSA® system does not operate independently. Instead, it serves as an advanced tool that supports the surgeon throughout the procedure.
During surgery, the ROSA® system uses optical trackers and a small camera attached to the patient’s leg to monitor the precise position of the knee in real time. This allows for adjustments to be made even with the slightest movements, ensuring that the surgical plan is carried out with high accuracy. The system continuously provides real-time data to the surgeon, enhancing their ability to place the knee implant with exceptional precision.
Postoperative Care and Recovery
Recovery from robotic total knee replacement with the ROSA® system is generally faster than with traditional methods, due to the minimally invasive nature of the procedure. Postoperative care typically includes:
- Pain Management: Some stiffness and pain in the operated knee are common.
- Wound Care: Instructions will be given for caring for the surgical incision, along with guidelines for activities such as driving and bathing.
- Nutrition: A balanced diet rich in iron is recommended to support wound healing and restore muscle strength.
- Exercise Program: A personalized exercise program is introduced a few weeks after surgery to strengthen the leg muscles and improve the range of motion.
- Resumption of Activities: Most patients can return to normal activities within a few weeks after surgery.
- Follow-up: Postoperative follow-up is carried out to monitor recovery progress and address any concerns.
Risks and Complications
Although robotic total knee replacement with the ROSA® system is generally safe, it is important to understand that, as with any surgical procedure, there are potential risks and complications. These may include:
- Pain: Postoperative pain is common and can be managed with medication.
- Bleeding: Some bleeding is expected during and after the procedure.
- Infection: Although rare, infection may occur and requires immediate treatment.
- Knee Stiffness or Instability: Some patients may experience stiffness or instability in the knee joint.
In conclusion, the ROSA® Knee System offers a revolutionary approach to total knee replacement, delivering increased precision and personalized care. By combining advanced robotic technology with the expertise and skill of orthopedic surgeons, this system aims to improve outcomes and patient satisfaction. If you are experiencing knee pain due to osteoarthritis and are considering knee replacement surgery, consult your orthopedic surgeon to determine if the ROSA® Knee System is the right choice for you.
