Intellijoint Hip®

Intellijoint HIP is a surgeon-controlled, navigation tool for total hip arthroplasty (THA). It provides real-time, intraoperative measurements for accurate, easy and fast implant alignment for cup position, leg length and offset.

Its smart registration ensures measurements are not affected by intraoperative patient movement or anatomical variations.

About Intellijoint Hip®

As a navigation system, Intellijoint HIP helps lower the overall rate of complication and hospital readmission. It works with physicians to achieve the most efficient and successful THA outcome for their patients.

  • Suitable for primary and revision THA
  • Compatible with any standard surgical approach including Direct Anterior, Lateral and Posterior
  • No significant operating room time-added


Signs It Might Be Time For Hip Replacement Surgery


Pain in the hip area (or deep groin)


Limited mobility


Reduced range of motion

Osteoarthritis is the most common reason for these symptoms as it causes the cartilage to deteriorate, leading to bone-on-bone contact.

If you’re experiencing any of those—or all three—it’s time to have the conversation with your doctor. It’s hard physically and mentally to live with those limitations and often, a hip replacement will improve the quality of your life.

Cup position measurements are accurate to within less than three degrees.

Leg length measurements are accurate to within less than half a millimeter.

Offset measurements are accurate to within half a millimeter.

Hip Replacement Surgery:
What You Need To Know

Leading up to surgery

Total Hip Arthroplasty (THA)—more commonly known as hip replacement surgery—is one of the most successful orthopaedic procedures performed today. Let’s talk about what you can do to prepare for surgery.

You’ll need to arrange a ride home from the procedure. The anesthetic takes time to wear off and your doctor likely won’t want you to drive for a few weeks after surgery. That means you may also need help with shopping, cooking, bathing, and other household chores. Be patient with yourself as you heal. Surgery can be hard on the body so you’ll want to be ready. It might help if you picture what life will look like after–a dramatic reduction of hip pain and a significant improvement in your ability to be involved in common activities of daily life.

About the procedure

To explain hip replacement surgery in simplest terms, the surgeon will remove the bad bone and replace it with prosthetic parts. If you imagine a ball and cup fitting together, the cup gives the ball space to move around but not fall out. Hip replacement is like replacing the old ball with a shiny, new one and inserting a new cup.

The surgeon removes part of your femur (the long bone in your thigh) and replaces it—that’s the ball. Then they clean out the acetabulum (a concave surface of your pelvis) and insert a liner—that’s the cup. What was once bone rubbing on bone, then becomes a smooth operating, prosthetic joint.

Surgeons use different approaches (like direct lateral or posterior) but the procedure is relatively similar. Your surgeon may also use navigation, like Intellijoint HIP, to help with measurements for cup position, leg length, and offset.

Leg length is obvious; you want your legs to be the same length after the surgery. The cup position and offset are important for the joint’s stability and range of motion. Surgeons are highly skilled at placing implants and tools like our navigation system help them be even more precise.

Recovering from hip replacement surgery

THAs are typically successful at providing a pain-free joint that restores your full range of motion. A good surgical outcome allows you to regain mobility in your daily activities. Often, patients are back on their feet the same day of surgery—with help, of course. Within a few days, you’ll be walking and doing light exercises to regain your joint’s motion. You can expect to start physiotherapy 1-2 weeks after surgery unless directed otherwise.

Your doctor will advise you of certain movements and activities to avoid, like driving because it involves rotating your foot when you move between pedals. Follow to their advice to give your hip the best chances of a speedy recovery. Typical exercises that they’ll suggest include: rotating your ankles in circles, bending your feet up and down, and flexing and extending your knees while lying down. And walking will promote blood circulation in your legs.
