Minimally invasive total knee replacement surgery is accomplished through a shorter incision. The incision is approximately 4 to 6 inches versus 8 to 10 inches for a traditional total knee replacement surgery. The smaller incision the less tissue disturbance. In addition to a shorter incision, the technique used to open the knee is less invasive. The artificial implants used are the same as those used for traditional knee replacement. However, specially designed surgical instruments are used to prepare the femur and tibia and to place the implants properly. Some minimally invasive surgeries are done with robotic technology that allows more precise control over the surgery.
How long is recovery from minimally invasive knee replacement?
The typical hospital stay is similar to a traditional knee replacement surgery of 1 to 4 days. Most patients are back to full activities in about three months after the operation.
Who is a candidate for minimally invasive knee replacement?
The best candidates for minimally invasive knee replacement surgery are younger, healthy, motivated and energetic patients with a smaller body type.
Is minimally invasive knee replacement surgery safe?
Minimally invasive surgery is generally less risky than traditional surgery. All surgeries come with risk of complications with anesthesia, bleeding and infection.
