Knee Replacement Arthroplasty

During a joint replacement procedure, your surgeon will strive to ensure that everything is aligned properly. Accurate alignment of the hip or knee components is critical to the overall function of your new joint, and it also plays a role in helping your joint feel healthy again, and helping the joint replacement to potentially last longer. Computer-assisted technology has made it possible for your orthopaedic specialist to navigate joint replacement procedures with a level of accuracy so precise it may improve the results of your surgery.

Computer Assisted Joint Replacement

Surgical Navigation

Surgical navigation is an image-guided technique that help surgeons to perform more accurate and safer surgeries.

Computer tomography

Computed tomography (CT) scanning is a noninvasive X-ray based imaging technique that produces cross-sectional images of the body that can be viewed on a computer or even printed. CT imaging differs from X-rays in that the internal structures are not superimposed and so can reveal more anatomical details. A CT scanner is a large machine in the shape of a box with a short tunnel in the center.

You will be lying over an examination table that moves into and out of the tunnel while the X-ray tube located in the circular gantry rotates around you. Electronic X-ray detectors housed within the gantry measure the emitted X-rays and sophisticated computers make up a picture of the cross-sectional anatomy.

Computed tomography is most accurate and can image bone, soft tissues and blood vessels at a time and also serves as an excellent tool to assist during interventional procedures such as needle biopsies.

Intraoperative fluoroscopic images

Fluoroscopy is a medical imaging technology that uses radiography or a continuous X-ray beam passing through your body to produce real-time moving images on a monitor. It is used as a diagnostic tool to study the movement of body parts or instruments inside the body during surgery, and also guides your doctor while performing operations such as cardiac catheterization, injections to the spine, and insertion of devices such as stents and catheters.
