Knee replacement surgery in South Denver

The expert orthopedic surgeons at Sky Ridge Medical Center are here to treat your knee pain and help you return to your daily activities. Healthy knees have smooth cartilage that cushions the bone’s movement, but over time the cartilage can wear down and cause the bones to rub against each other.

Our specialists will access your condition and recommend knee replacement surgery if you:

  • Experience persistent swelling in the knees
  • Are unable to get a full night’s rest due to your knee pain
  • Have legs that bow in or out

Types of knee replacement surgery

Patients can receive either a partial or total knee replacement surgery depending on the condition of their knee(s) and what compartments are damaged. The knee has three compartments:

  • Medial—inside aspect of the knee
  • Lateral—outside of the knee
  • Patellofemoral—in front of the knee

During a partial knee replacement, only the affected compartments of the knee are repaired. The medial compartment is frequently affected by osteoarthritis, so patients who only have damage to their medial compartment will receive a partial knee replacement if the other two compartments are in a healthy condition.

If all three compartments are damaged, patients will receive a total knee replacement, which also includes removing the ligaments.

Minimally invasive robotic surgical technology

When possible, our board-certified orthopedic surgeons at Sky Ridge use MAKOplasty® robotic surgery technology when performing partial and total knee replacement surgery. MAKOplasty is used to treat early to mid-stage osteoarthritis of the knee (the most common form of arthritis).

Using MAKO technology, our orthopedic surgeons can provide you with a personalized surgical plan formed from your unique anatomy. The MAKO System software uses a CT scan to create a 3D model of your knee to assist our surgeons during the operation.

Benefits of robotic knee surgery with MAKOplasty

Compared to patients undergoing traditional open surgery, MAKOplasty patients may experience:

  • A shorter hospital stay
  • Quicker recovery
  • A smaller incision as compared to total knee replacement

In addition, many return to an active lifestyle within weeks of the procedure. “MAKOplasty allows us to treat patients with knee osteoarthritis at earlier stages and with greater precision. Because it is less invasive and more of the patient's actual knee remains, it offers a more natural knee motion post-operatively," says Susan Hicks, CEO of Sky Ridge.

Candidates for minimally invasive knee surgery

Although the best treatment for each patient must be determined individually, patients determined to be a good fit for MAKOplasty® typically share these following characteristics:

  • Knee pain with activity, on the inner knee, under the kneecap or the outer knee
  • Start-up knee pain for stiffness when activities are initiated from a sitting position
  • Failure to respond to non-surgical treatments or non-steroidal, anti-inflammatory medication
  • Early- to mid-stage osteoarthritis of the knee and damage is localized to one or two knee compartments
  • Aren’t quite ready for a total-knee replacement and is looking for a less-invasive knee surgery
  • Not bow-legged or knock-kneed more than 15 degrees

How long do the implants used in this procedure last?

All implants have a limited life expectancy that depends on several factors, including a patient’s weight, activity level, quality of bone stock and compliance with doctor’s orders. However, alignment and positioning are also key factors affecting the life expectancy of an implant. The goal of the MAKOplasty® procedure is to achieve the absolute best alignment and positioning for your implant to help it last as long as possible.
