Peer Partners Offer Encouragement and Support to Joint Replacement Patients

When it comes to innovation and improvement, Virginia Mason recognizes that patients are a valuable resource. This is especially true in the Peer Partners program. When former joint replacement patients were asked what could be done to improve their experience, many said they wished they’d been able to talk with someone who had recently gone through a hip or knee replacement.

Patient Relations Program Manager Ann Hagensen, RN, realized the value of that suggestion. She and her team worked with patients to design the Peer Partners program. Now in its third year, the program trains former patients to become volunteer peer partners. The volunteers round on the orthopedics unit, visiting patients. They also attend pre-surgical classes to reinforce the knee and hip surgery protocols. In an orientation session, peer partners are prepared to visit with patients by learning communication techniques that help them listen for topics that matter most to the patient. Often patients are excited to talk about activities they plan to get back to with a newly functional joint.

Following their training, peer partners move through the orthopedics unit, introducing themselves to patients who are scheduled for surgery or are in recovery. Volunteer Kent Smith, who has been a peer partner for two years, found the program to be very helpful to him when he underwent his own hip replacement. “I wanted to find a way to pay back for the great care I’ve received at Virginia Mason,” he says. “The caregivers here have wonderful hearts. They give the kind of care you always want to receive.”

Kent credits the Patient Relations training with transforming the way he communicates in all aspects of his life.

“It’s all about listening and letting people know you’re there for them,” Kent says. “The conversation may begin with a focus on their surgery, but often expands to include their personal lives. Patients want someone to listen to them. Our goal is to be a source of encouragement and motivation, to help them get the hard work of recovery done.”

Kent is not alone in his enthusiasm for the Peer Partners program. Ann says the one-on-one experience is so positive that many patients decide to volunteer before they leave the hospital, returning six months later for their training.

“This program is a win-win,” says Ann. “It’s a win for our patient partners who have this opportunity to help others and see their ideas become reality, and it’s a win for Virginia Mason, helping us create the perfect patient experience.”

Joint Replacement: The Right Procedure at the Right Time Can Improve Quality of Life

**By Kevin MacDonald, MD**

sr.coupleJoint replacement is a type of orthopedic surgery where parts of an arthritic or damaged joint are removed and replaced with a metal, plastic or ceramic device called a “prosthesis.” The prosthesis is designed to replicate the movement of a normal, healthy joint.

National statistics help explain why many orthopedic surgery practices around the country are busy. When you combine the number of baby boomers reaching “the golden years” with the pervasiveness of osteoarthritis – or degenerative joint disease – and the growing obesity epidemic, experts predict that by 2030 there will be almost 3.5 million total knee replacements and more than 570,000 hip replacements performed annually in the United States.

And while hip and knee replacements are the most commonly performed joint replacements, joint replacement surgery is also performed on the ankle, elbow, shoulder and wrist.

When to consider surgery

I remind all my patients that joint replacement surgery is elective and should come down to a quality-of-life decision. My advice almost always includes recommending that they try non-surgical treatments first – such as ice, heat, anti-inflammatory medication, swimming or physical therapy.

However, if nothing works, people should ask themselves if pain and disability are destroying their quality of life. If the answer is yes, I advise them that it’s the appropriate time to discuss surgical options.

Benefits, and some risks

The benefits of joint replacement surgery can be life changing – both physically and emotionally – when someone can walk and move without pain.

Studies have consistently shown that hip and knee replacement are some of the most successful procedures when it comes to improving patient satisfaction and quality of life. Most patients are able to resume activities that arthritis had made difficult, such as golfing, biking, caring for family members, or missing fewer work days due to pain.

As with any surgical procedure, there are potential risks associated with joint replacement surgery, including infection, nerve damage, loosening of the joint over time, or complications from the stress of surgery, such as a heart attack or blood clots.

Fortunately, long-term benefits of total joint replacement also include years of use. Other recent research has shown that 95 percent of hip replacements performed in the United States last 15 to 20 years, and 85 percent of knee replacements last two decades. In addition, improvements in surgical techniques, prosthetic designs, bearing surfaces, and fixation methods may allow implants to last even longer.

Types of joint replacement

Thanks to advancements in surgical techniques and rehabilitation, many orthopedic surgeons are able to offer patients in need of joint replacement a variety of surgical options – depending on individual factors like overall health, chronic disease and anatomy. Options include:

  • Posterior total hip replacement – This proven hip replacement method has a long-term track record of success. During this one- to two-hour surgery, a three- to six-inch incision is made over the damaged hip to expose deeper tissue. The damaged “ball” or head of the thigh bone (femur) is dislocated and removed. Damaged bone and cartilage in the “socket” are removed and the socket is smoothed and enlarged to receive the metal implant. A highly polished socket liner, which is usually made of polyethylene plastic, is secured inside the socket. The surgeon then creates a narrow, five-inch channel on top of the thigh bone to receive the new implant’s stem and ball. Materials in the new ball-and-socket joint press against one another easily to help restore hip motion.
  • Anterior total hip replacement – This procedure is very similar to a posterior total hip replacement, except the surgeon accesses the hip joint from the front, as opposed to the back side (posterior) of the hip. This method has gained a lot of interest over the past decade and patients can generally expect an excellent outcome, as they can from the posterior approach.
  • Revision hip replacement – After a period of normal wear and tear on an artificial hip joint, parts of the prosthesis may wear out or become loose. In these cases, hip revision surgery may be recommended. It is done to repair a prosthesis that has been damaged over time due to infection or normal wear and tear. Revision surgery helps correct the problem so the hip can function normally.
  • Partial knee replacement – Also known as unicompartmental knee arthroplasty, this procedure is appropriate for people who are in good health and have exhausted conservative measures for managing knee pain. These patients may have had a torn meniscus (cartilage) or avascular necrosis (dead bone tissue) in the past that later led to arthritis in one part of the knee. For younger adults, a partial knee implant may help prevent further degeneration in the joint and the need for total knee replacement. Older adults may also be candidates, which is then expected to last the remainder of their lives.
  • Total knee replacement – The implant usually consists of two parts made of chrome cobalt, titanium alloy and polyethylene plastic. The cobalt-chrome part is attached to the end of the thigh bone (femur) and a titanium alloy base plate is attached to the end of the leg bone (tibia). A polyethylene plastic “articulating” surface is then positioned between them. A polyethylene plastic “button” is attached to the undersurface of the knee cap (patella). Knee implants come in various sizes to fit every knee.
  • Revision knee replacement – A knee replacement may fail over time for various reasons. If this occurs, a knee can become painful, swollen, stiff or unstable, making it difficult to perform everyday activities. If a knee replacement fails, your doctor may recommend a second surgery, called a revision total knee replacement. In this procedure, an orthopedic surgeon removes some or all of the original prosthesis and replaces it with a new one. Revision surgery is a longer, more complex procedure than total knee replacement. It requires extensive planning, as well as specialized implants and tools.

Improving your odds of success

No matter which joint replacement surgery may be most appropriate for any one patient, there are things people can do to help improve their odds of realizing the benefits of surgery, including:

  • Losing weight, if necessary
  • Quitting smoking
  • Limiting alcohol use
  • Muscle-strengthening exercises
  • Making sure other medical conditions, such as diabetes, are under optimal control

Making a personal decision


Like every surgery, deciding whether to have joint replacement is – and should be – a very personal choice. Knowing that, my final recommendation is straightforward: Work with your doctor to fully understand the plan for managing your individual risk factors before and after joint replacement.

If that’s done well, there is a good chance that the long-term advantages of joint replacement surgery will outweigh the short-term risks.
