Steps Involved in Knee Replacement Surgery

Knee replacement surgery involves several important steps that contribute to the overall time it takes to complete the procedure. These steps are carefully performed by a team of skilled surgeons and healthcare professionals to ensure a successful outcome. Let’s explore each stage of the surgery in detail:

Anesthesia: Before the surgery begins, the patient will be given anesthesia to ensure they are comfortable and pain-free throughout the procedure. This can be either general anesthesia, where the patient is asleep, or regional anesthesia, where only the lower part of the body is numbed.
Surgical Incision: Once the anesthesia has taken effect, the surgeon will make an incision on the front of the knee. The length of the incision may vary depending on the specific case, but it is typically around 8 to 12 inches.
Preparing the Bones: The damaged bone and cartilage are carefully removed from the ends of the thigh bone (femur) and shin bone (tibia). Special precision instruments are used to shape the bones so that they can accommodate the artificial knee components.
Implant Placement: Next, the artificial knee components are securely attached to the prepared bone surfaces. The components typically consist of a metal femoral component that replaces the lower end of the thigh bone, a metal tibial component that replaces the upper end of the shin bone, and a plastic spacer placed between the two metal components to allow smooth movement.
Closing the Incision: Once the components are in place, the surgeon carefully closes the incision with stitches or clips. The incision is then covered with a sterile dressing to promote healing.

This entire process typically takes about 1 to 2 hours to complete, depending on the complexity of the case. It’s important to note that these time estimates are general and can vary based on individual factors. Your surgeon will provide you with more specific information regarding the expected duration of your surgery.

Being informed about the steps involved in knee replacement surgery can help you understand the procedure better and alleviate any concerns you may have. Remember to consult with your healthcare team for personalized information and advice related to your specific case.
