The use of robotic arms in Hong Kong is becoming increasingly widespread, covering various types of surgeries including Orthopedic, spine, and urology. Taking robotic-assisted total knee replacement surgery as an example, the Orthopedic surgeon first inputs the patient’s leg data into the computer to pre-determine the size and position of the artificial joint prosthesis.
During the surgery, the doctor register patient’s bony anatomy into to the computer, then uses instruments to match that with computer’s preoperative data. Next, the doctor places sensors to assess the tension and balance of the ligaments. Based on the bone size and ligament tension, the position of the prosthesis is determined before proceeding with the bone cutting step.
Throughout the entire surgical process, the robotic arm continuously assists the doctor in precisely executing the surgical plan. The bone cuts are highly accurate and smooth, allowing the use of “cementless prostheses.” This type of prosthesis enables cells to grow directly on the implant’s surface, making it more stable, durable, and longer-lasting.
Using robotic-assisted surgery significantly improves precision, reduces blood loss and damage to soft tissues, thereby decreasing post-operative pain and accelerating the recovery process.
