Knee Replacement

Knee replacement surgery may be right for you if you have ongoing knee pain, even with ongoing nonsurgical treatment. Knee replacement surgery can help relieve pain and restore function in severely diseased knee joints.

At OrthoMed Center, our board-certified orthopedic surgeons and expert staff will guide you through the treatment process and help you decide what is right for you.

Determining If A Knee Replacement is Right For You

Determining If
A Knee Replacement
is Right For You

Knee replacement surgery is often recommended for people who have severe pain caused by osteoarthritis, affecting their ability to walk, climb stairs, and get in and out of chairs. Some people even have knee pain at rest. 

In determining if a knee replacement surgery is right for you, your orthopedic surgeon will consider your age, weight, activity level, knee size and shape, and overall health. He will also examine your knee to assess your range of motion, stability, and strength. X-rays may be ordered to help determine the extent of damage.

Knee Osteoarthritis

Knee osteoarthritis (OA) is typically the result of wear and tear and progressive loss of articular cartilage. Knee osteoarthritis is also known as degenerative joint disease. It is most common in the elderly. 

Articular cartilage is the smooth coating that covers the surface of the bones inside the knee. It also cushions and helps lubricate the joint surfaces. In osteoarthritis, this coating is damaged, leading to reduced lubrication and cushioning. The articular cartilage begins to degrade, and over time it can thin or form cracks. Pieces of cartilage may come loose and float inside the knee, further irritating the joint. After a long period of time, the cartilage can become completely “worn away,” and the bones begin to rub together, causing considerable pain.

Eventually, osteoarthritis may lead to disability, as it is a progressive disease. Typically, clinical symptoms become more severe, more frequent, and more debilitating over time. The rate of progression and intensity of clinical symptoms varies for each individual.

Prevalence of Knee Osteoarthritis

Osteoarthritis, also known as “wear and tear” arthritis, is the most common type of arthritis. The word arthritis means inflammation (swelling) of a joint.

Knee osteoarthritis is the most common type of arthritis diagnosed, and its prevalence will continue to increase as life expectancy and obesity rises. Depending on the source, roughly 13% of women and 10% of men 60 years and older have symptomatic knee osteoarthritis. Among those older than 70 years of age, the prevalence rises as high as 40%. The prevalence of knee osteoarthritis in males is also lower than in females. Interestingly, not everyone who demonstrates radiographic findings of knee osteoarthritis will be symptomatic.

How Arthritis Causes Knee Pain

Knee arthritis is a common problem that affects many patients. It is a degenerative condition that can be very painful and may limit your daily activities.

The knee joint is formed by the lower end of the femur (thighbone), the upper end of the tibia (shinbone), and the patella (kneecap). C-shaped wedges of tissue called menisci act as shock absorbers in the knee, and ligaments hold the joint together. The bones in the joint are covered with articular cartilage, a tissue that protects the bones and allows the joint to glide smoothly with movement.

Arthritis can damage the articular cartilage in the knee, either with wear and tear over time or due to inflammatory conditions like rheumatoid arthritis. Eventually, the cartilage can wear away completely in places, causing the bones to rub together. This condition can be very painful and limit knee function, making even simple movements like walking or bending difficult.

Eventually, arthritis damage can progress to the point that nonsurgical treatments are not effective in relieving pain. In these cases, our orthopedic surgeons may recommend knee replacement surgery.

Treatment for Knee Osteoarthritis

Every osteoarthritic knee is different, and OrthoMed offers a team approach to treatment. While there is no known cure, knee replacement surgery is effective in reducing pain, controlling swelling, and helping patients maintain and improve mobility of the knee. 

Types of Knee Replacement Surgery

Depending on the location and severity of knee arthritis, different surgical options are available for knee replacement. Knee replacement surgery eliminates or reduces joint pain, increases mobility, and improves quality of life. At OrthoMed Center, our orthopedic surgeons have expertise in total knee replacement and partial knee replacement procedures.

Partial Knee Replacement

If your arthritis is limited to only one side of the knee, partial knee replacement may be an option. During a partial knee replacement, only the damaged side of the knee is replaced with prosthetics, and the healthy bone remains. Partial knee replacement also allows for quicker recovery times and less pain in recovery when compared to a total knee replacement.

Total Knee Replacement

If arthritis damage is not limited to only one part of the knee, total knee replacement is likely the best option to improve knee function.

Knee replacement surgery involves removing the damaged portions of the knee and replacing them with prosthetic components. The damaged bone is replaced with metal implants, and a medical-grade plastic spacer is inserted between the metal implants to allow the new knee to glide with movement.

For many patients with severe knee arthritis, this is a very successful procedure that effectively reduces knee pain and improves function.

Recovery After Knee Replacement Surgery

Most knee replacement procedures require a hospital stay of 1-3 days. Patients start physical therapy as soon as possible after surgery, as this is a critical part of recovery to strengthen the knee and restore motion.

Most patients can resume their normal activities within 3 weeks of surgery, and full recovery is generally about 6 weeks.

Risks Associated With Knee Replacement Surgery

The risks associated with knee replacement surgery may include:

  • Infection in the Joint
  • Blood Clots
  • Implant Problems (e.g., loosening)
  • Wear
  • Nerve Injuries

If after surgery you experience any of these problems, be sure to contact your surgeon immediately.

To reduce the risk of infections and blood clots, we use antibiotics and blood thinners. We also take precautions in the operating room to reduce the risk of infections. 

As a patient, there are also things you can do to reduce your risk of infections, including losing weight, quitting smoking, and controlling your blood sugar. If you need help in any of these areas, talk to your surgeon. There are resources available to help you.

Results You Can Expect from Knee Replacement Surgery

According to the American Academy of Orthopaedic Surgeons, more than 90% of patients who undergo knee replacement surgery experience dramatic relief of knee pain and a significant improvement in performing everyday activities.

Patients should also be aware that total knee replacement does not allow them to do more than before they developed arthritis. Your surgeon will advise against high-impact activities such as running, jogging, jumping, or other high-impact sports, as excessive activity may speed up the normal wear of the implants.
