What is a Hip Replacement?

The surgery replaces parts of the joint with artificial implants. The ball (head of the femur) and socket (acetabulum) are both replaced. The goal of the procedure is to allow you to return to your daily activities and resume sports more comfortably.

Who Can Benefit From a Hip Prosthesis?

Dr. Benoit may recommend a hip replacement if you feel pain, inflammation and have severe hip joint damage as a result of the following conditions:

  • Osteoarthritis (most common)
  • Rheumatoid polyarthritis
  • Osteonecrosis (avascular necrosis)
  • Injury, such as a hip fracture
  • Tumor in the hip joint
How to Know if you Need a Hip Replacement?

When hip pain affects your quality of life, it may be time to replace the hip. Signs of a decrease in quality of life include:

  • Difficulty doing simple daily tasks such as walking, getting dressed, putting on shoes, going up and down stairs, simply standing up, etc.
  • Inability to fully take part in activities you enjoy
  • Inability to have good sleep quality because of pain

At first, Dr. Benoit may recommend other treatment options such as medication to relieve pain or inflammation, walking aids, intraarticular injections and physical therapy. If these do not alleviate the pain and stiffness, hip arthroplasty may be necessary to restore function and improve your quality of life.

The surgery

During a total hip arthroplasty, the ball and socket of the joint are replaced.

How Will Dr. Benoit Approach Your Hip?

There are three commonly used techniques to approach the hip joint:

  • From the front (anterior approach to hip replacement)
  • From the side (lateral approach to hip replacement)
  • From the back (posterior approach to hip replacement)
What Size Will the Incision Be?

A minimally invasive hip replacement aims to reduce the impact of surgery on healthy muscles and blood vessels. Although the posterior approach to the hip was first promoted as a minimally invasive procedure, today orthopedic surgeons can use minimally invasive methods with all surgical techniques for the hip. Dr. Benoit will discuss the different methods that may deliver the best results for you.

Minimally Invasive Hip Replacement
When the surgery is minimally invasive, the hip joint is accessed through a small incision to minimize muscle trauma. This approach can have some advantages such as:

  • Lower risk of muscle injury
  • Less pain
  • Faster and easier recovery
  • Less limping
  • Shorter hospital stay
  • Lower risk of hip dislocation

Minimally invasive hip replacement is not for all patients. Your age, weight, physical condition, and other factors will inform Dr. Benoit’s recommendations in this regard.

Traditional Hip Replacement
A conventional hip replacement usually requires only one incision for the surgeon to access the hip: either from the side (lateral approach) or the back (posterior approach). Recovery after traditional hip replacement can take time since some muscles and tendons are injured during the procedure to reach the joint (the muscles and tendons are repaired once the hip implants are in place). You may be at risk of dislocation until all the supporting structures of your new hip are healed.

During your consultation, Dr. Benoit will discuss the surgical approach best suited for you.

Components of a Hip Prosthesis

There are two parts:

  • A ball is attached to a metal stem and is inserted into the thigh bone (femur).

  • A metal cup and its interior lining for fixation to the female part of the hip joint (acetabulum), allowing the artificial joint to turn smoothly. The implants are made of metal or ceramic. During your consultation, Dr. Benoit will discuss which type of implant is right for you.

Implant Fixation to the Bone

Biological fixation involves a non-cemented implant that adheres to the bone by its porous coating, allowing the bone to naturally bond with the implant. For a cemented implant, fixation is achieved with bone cement which acts as glue. The cemented and non-cemented techniques are the two possible options to secure the implant.

Replacing Both Hips at the Same Time

The left and right hip can be replaced in a single procedure. An arthroplasty of both hips is also called a bilateral hip arthroplasty. If you have issues with both your hips, Dr. Benoit may recommend a dual hip replacement (bilateral) if you are in good health and can tolerate the procedure.

What Happens During a Hip Replacement Surgery?

Hip arthroplasties are performed in a surgical center. They are often completed as same day surgery, although you may need to stay for a night or two for observation or to deal with complications. Typically, a total hip arthroplasty without any complications includes the following steps:

  • Once in the operating room, you will undergo general anesthesia (entire body) or anesthesia below the waist (epidural or spinal), according to the recommendation of your anesthesiologist and/or Dr. Benoit.
  • Dr. Benoit will position you adequately for the surgery. The surgical site will then be cleaned with soap and sterilized with an antiseptic solution. 

  • Incision and approach to the hip.
  • The head of the femur is removed.
  • The pelvic cavity is prepared
  • The cup is impacted within the cavity. The interior lining is installed.
  • The femur is prepared and a trial implant is installed.
  • Different trial implants are used to determine the best choice for you.
  • The definitive implants are then installed.
  • The hip is reassessed to make sure that it functions correctly.
  • The tissue layers will be closed with sutures. The outermost skin layer will be closed with surgical glue. There will be no need to remove any sutures after the surgery.
  • You will be transported to the recovery room.

Dr. Benoit will tell you when you can return home safely, which may be the same day, depending on your condition.

How long does a hip replacement surgery take?

On average, hip replacement surgeries take less than one hour. A dual hip arthroplasty may take more time. Complications during surgery may also extend the time of surgery.

Some imaging techniques, such as x-rays, may be necessary immediately after surgery or over the course of your rehabilitation to confirm that the procedure was successful and that your hip is healing well. 

Recovery After a Hip Replacement

Recovery after a hip replacement starts immediately. You will be encouraged to get up and move around as soon as possible after the surgery. Patients without any other health issues can expect to return home as soon as they can walk, climb stairs and get in and out of a car.

Some patients may spend time in a rehabilitation center or hospital to prepare for an autonomous return to home life. Whether you are returning home or going to a rehabilitation center after the surgery, you will need physiotherapy to help you regain muscle strength and a good range of motion.

The physiotherapist can guide you on when you will be ready to walk with or without assistance and how to manage your pain. Your motivation and cooperation to complete your physical therapy sessions are essential for an efficient recovery process and the overall success of the surgery.

During your recovery be sure to:
  • Keep the surgical area clean and dry. You will receive instructions before returning home.
  • Take all your medication as indicated.
  • Follow the recommendations of your physiotherapist and complete all the prescribed home exercises.
  • Resume your normal eating habits unless indicated otherwise.
  • Elevate your leg and use ice to control swelling.
  • Do not drive until Dr. Benoit has authorized it.
  • Clear liquid or blood may leak from your incision. This is normal in the first days after surgery.
  • Immediately inform Dr. Benoit’s office if there is redness, swelling, increased drainage from the incision, a high fever, chills or intense pain.

What Are the Risks of a Hip Arthroplasty?

Most hip replacement surgeries are successful. Like any other surgery, there are some risks during and after hip arthroplasty:

  • Bleeding
  • Infection
  • Blood clots in the legs or lungs
  • The discrepancy in leg length

  • Injury to the neighboring nerves
  • Fracture
  • Continued pain or stiffness
  • Dislocation
  • Prosthetic loosening or wear
  • Joint pain that is not relieved (this may be temporary or permanent)

There may be other risks depending on your overall health.

After the Surgery, Inform Your Physician if you Notice One of the Following:
  • Fever
  • Redness, swelling, bleeding or drainage at the site of the incision that does not stop after a few days
  • Increased pain around the incision area
  • Pain in the lower leg that is not linked to the incision
  • New or increased swelling of the lower part of the leg
Call 911 or Go to the
Emergency if you Feel:
  • Chest pains
  • Shortness of breath
  • Extreme hip pain that suddenly makes it impossible to move (dislocation of the prosthesis).
