Broadly speaking, knee replacement surgery can be carried out either through the traditional approach or the newer minimally invasive approach (MIS), also known as the quadriceps-sparing approach. It allows surgeons to insert the same artificial implant through a shorter incision. This surgical approach avoids trauma to the quadriceps muscle, which is the most important muscle group around the knee, thereby allowing quicker recovery time, including walking and knee-bending movements.
1. Smaller Incisions: Minimally invasive surgery involves making small, precise incisions, which reduces trauma to the body compared to traditional surgery.
2. Specialized Instruments: The procedure uses specialized tools, such as small cameras (endoscopes) and surgical instruments, that allow surgeons to operate with minimal disruption to surrounding tissues.
3. Reduced Risk of Infection: Due to the smaller incisions and less tissue damage, minimally invasive surgery typically results in a lower risk of infection compared to traditional open surgery.
4. Shorter Recovery Time: Patients often experience faster recovery times because of less tissue disruption, leading to a quicker return to daily activities.
5. Less Scarring: Smaller incisions lead to less visible scarring, which can improve the cosmetic outcome and reduce the psychological impact on the patient.
