Knee Replacement

Elective, Non-urgent and Non-emergency Procedures Postponed

Memorial Healthcare System and Joe DiMaggio Children’s Hospital are committed to placing the safety and well-being of our patients, staff, and physicians first. Due to that commitment and the recent surge in COVID-19 positive cases, Memorial has decided to postpone all elective, non-urgent and non-emergency surgeries/procedures effective Wednesday, July 8, 2020 until further notice. Although our offices will be contacting those who already have a surgery/procedure scheduled, we encourage you to contact your physician’s office to discuss next steps.

Starting Monday, July 13, all Memorial Physician Group adult specialties will continue to offer appointments for telehealth and phone visits. In-person office visits are on a case by case basis until further notice.

We appreciate your patience during this time of uncertainty. One thing that is certain is Memorial’s commitment to keeping its community safe and healthy.

Total Knee or Partial Knee Replacement

Total knee replacement involves the replacement of all three surfaces—femur, tibia and patella—with metal and plastic components. Partial knee replacement involves the replacement of only one knee compartment (medial, lateral or patellofemoral) and may be an option for those who have painful, debilitating arthritis limited to one area of the knee. Only your doctor can determine if you are a candidate for this procedure.

During partial knee replacement, the surgical incision is usually smaller, resulting in less soft tissue trauma to and around the knee. Since more of the native knee is preserved, your knee may feel more natural than after a total knee replacement.1 Other potential benefits to partial knee replacement include:

  • Accelerated rehabilitation1
  • Faster operation
  • Shorter hospital stay compared to a total knee replacement1
  • Decreased post-surgical pain

How Long Will My Knee Replacement Last?

All knee replacements can wear out over time, including total knee replacements. How long a particular implant may last varies from patient to patient and depends on a number of factors including the patient’s weight, activity level and the accuracy of the implant’s placement. In general, many partial knee replacements do not last as long as total knee replacements. However, the factors causing this are complicated and should be discussed with your doctor.

What Are the Risks?

The primary benefit of knee replacement surgery is pain relief. As pain improves, function usually improves too. This surgery is extremely effective, but of course there are no guarantees. Additional risks of surgery, for both partial and total knee replacement, include:

  • Blood clots in leg veins (venous thromboembolic disease)
  • Fractures
  • Infection
  • Loosening of implant
  • Nerve or blood vessel damage

Your surgeon and healthcare team will take great care to minimize the risk of these and other complications. Keep in mind that complications are rare, but they need to be understood by you and your family. Your surgeon will be happy to answer any questions.
