Dr Wang Lushun: Robotic Knee Surgery promises better outcomes and faster recovery

Robotic Knee Replacement is more and more used nowadays as opposed to a conventional knee replacement, offering several advantages. This interview we had with Dr Wang Lushun explains exactly what they are and the benefits this brings.

Rosa Robotic Knee Assistant

The ROSA Knee System is a robotic surgical assistant developed by Zimmer Biomet that allows surgeons to carry out knee replacement procedures with greater precision.
In general, the surgical procedure using the ROSA knee system is like a traditional total knee replacement. The surgery is performed entirely by the surgeon by prompting the robot (the assistant) as per the personalized plan, with a high degree of precision, developed by your surgeon. During the surgery, the ROSA Knee utilizes optical trackers and a mini camera attached to the leg to determine the exact position of the knee in space. Throughout the procedure, the surgeon is provided with real-time data by the ROSA Knee System, which enhances the surgeon’s skill enabling accurate placement of the knee implant.

Advantages of the ROSA Robotic Total Knee Replacement

Being a minimally invasive approach, the ROSA knee system offers the following benefits:

Smaller incisions with reduced scarring and minimal blood loss
Less post-operative pain
Shorter hospital stay and recovery period
Quicker return to daily activities
Lower incidence of complications
Precise placement of the implant
Reduced injury to adjacent tissues
Increased longevity of the implant

Postoperative Care and Recovery

Recovery is quick as it is a minimally invasive procedure. In general, postoperative care and recovery involves:

Medication to manage the discomfort, stiffness and pain in the leg.
Instructions on surgical site care, and bathing
Recommendation of a balanced diet rich in iron supplements to help heal the wound and restore muscle strength.
Maintenance of healthy weight to minimize stress on the joint.
Refraining from smoking
Refraining from any strenuous activities requiring weight bearing.
Advice on a customized exercise regimen after a few weeks following surgery to strengthen leg muscles and improve range of motion.
