Minimally Invasive Surgery (MIS)

MIS Joint Replacement offers important advantages, requiring smaller incisions and potentially causing less trauma, shorter hospital stay, faster recovery and less scarring than traditional techniques.

Partial Knee Resurfacing

Partial knee resurfacing (PKR) is a surgical procedure for relieving arthritis in one compartment of the knee. With PKR, only the damaged surface of the knee joint is replaced, helping to minimize trauma to healthy bone and tissue.

Rotator Cuff Repair

A rotator cuff tear is a common cause of pain and disability among adults. A torn rotator cuff will weaken your shoulder. This means that many daily activities, like combing your hair or getting dressed, may become painful and difficult to do.

Considering Shoulder Replacement Surgery?

Is shoulder replacement surgery right for you? Do you experience any of the following:

  • Inability or difficulty performing daily functions such as work or sports.
  • Treatments and medications for pain relief are ineffective (cortisone injections, physical therapy, or anti-inflammatory medications).
  • A feeling pain and weakness in the joints or irregular motion of the shoulder.

Understand Your Body and Its Signals

Before we evaluate your condition, let's start by first breaking down the anatomy of the shoulder so you can understand two points: how the “nuts and bolts” (or in this case bones, bones, joints, ligaments, tendons and muscles) work together to give you that long drive and what happens when they rust (arthritis and joint degeneration).

How Shoulders Function

First and foremost, the shoulder is made up of three bones: the collar bone (clavicle), the upper arm bone (humerus), and the shoulder blade (scapula). The nuts and bolts that hold these bones together are an integral mechanism for the elaborate design of the ball-and-socket joint. Basically, the ball (or head) of your upper arm inserts into the shallow socket (glenoid) of your shoulder blade. As a result, this joint has greater range of motion than any other joint in the body.

What Causes Shoulder Pain

There are several types of conditions that cause acute and moderate shoulder pain that cause patients to consider shoulder joint replacement surgery. Let's go over a few of these below:

Osteoarthritis (Degenerative Joint Disease)
As the years go by, that swing sometimes takes a toll on your body. As your body ages, the cartilage that cushions the bones begins to wear away to the point that your bones rub against one another, which results in discomfort and stiffness.

Rheumatoid Arthritis (RA)
RA is the most common form of inflammatory arthritis that affects the wrist and fingers. This type of arthritis is a result of the synovial membrane (soft tissue) surrounding the joint becoming inflamed. Persistent inflammation ruthlessly damages the cartilage and leads to a loss of cartilage, pain, and stiffness, thereby trading that birdie for a bogey.

Post-traumatic Arthritis
So you're having trouble with that backswing after "recovering" from a shoulder injury. Post-traumatic arthritis may occur due to an older shoulder injury not healing properly. As a result of improper healing, the joint becomes irregularly smooth and leads to even more joint wear.

Rotator Cuff Tear Arthropathy
The rotator cuff muscles can be strained and torn due to over-swinging or poor swinging. Unusually large tears can often develop cuff tear arthropathy, which can result in loss or deformity of the joint cartilage.

Orthopaedic Evaluation

Your family physician may have begun diagnosing and treating your symptoms. Should this management fail, a consultation with an Orthopaedic Surgeon may be necessary to determine the right course of action. An Orthopaedic Surgeon will provide a thorough evaluation of the surgery and its benefits through:

  • An examination of your previous medical history.
  • A physical exam to assess the strength and stability of your shoulder.
  • X-Rays (assess damage, loss of joints, etc.)

After Dr. McLennan has reviewed the results of your evaluation, he will discuss whether shoulder joint replacement surgery is right for you to relieve pain and reinstate regular daily function. If surgery is not right for you, your surgeon will discuss other forms of treatment such as injections, physical therapy, or other types of surgery.

Types of Shoulder Replacements

Depending on the type of shoulder replacement surgery, artificial shoulders can consist of the following:

  • Total Shoulder Replacement: replacing the arthritic joint with a metal ball attached to a stem and plastic socket.
  • Stemmed Hemiarthroplasty: replacing the head of the humerus with a metal ball and stem.
  • Resurfacing Hemiarthroplasty: replacing the joint surface of the humeral head with a prosthetic cap without a stem.
  • Reverse Total Shoulder Replacement: switching the socket and metal ball to amend serious arthritis or failed shoulder replacements.

Before the scalpel comes into play, consult with your doctor about potential side effects and after-surgery care.
