Why are knee replacements needed?
The knee is protected by cartilage, a smooth, rubbery tissue that cushions the joint. If the cartilage in your knee becomes worn or damaged, moving your knee can become painful. Knee replacements can be used to treat severe cases of
How to know if you need a knee replacement
The best way to know if a knee replacement is the right treatment for you is to talk to an orthopedist. However, consider talking to your doctor if you notice any
- Your knee pain no longer responds to nonsurgical treatments
- Your knee pain is getting more intense and frequent
- Your mobility has become increasingly limited
- You notice consistent or recurring swelling in your knee
- You’re not able to do the things you love

Types of knee replacements
We perform four different types of knee replacement surgery.
Partial knee replacement
During a partial knee replacement, also called unicompartmental knee replacement, only part of your knee is replaced. This surgery is used when knee damage is limited to one compartment of the knee, the knee ligaments are intact and there aren’t significant alignment issues.
We’ll only remove the damaged cartilage and leave the healthy tissue in place. This enables us to make a smaller incision, meaning partial knee replacement has a quicker recovery time than total knee replacement.
Total knee replacement
A total knee replacement, also called total knee arthroplasty, is a type of knee replacement surgery where your entire knee is replaced with an artificial one. During the procedure, we’ll remove the knee cartilage and resurface the kneecap to fit perfectly with the artificial joint.
Knee replacement revision surgery
Artificial knees can last more than 20 years, but ordinary use can cause them to wear out over time. In some cases, a knee replacement revision is needed to fix a damaged artificial knee. In rare cases, a revision surgery may be needed if there is an infection, a complication from surgery, or if the knee replacement surgery didn’t resolve your knee issues.
During a revision, we’ll replace the damaged parts of the artificial joint with new pieces. Depending on the condition of the joint, we may need to replace the entire joint or only part of it.
Patellofemoral replacement surgery
Patellofemoral replacement surgery replaces the area under the surface of the kneecap and the groove under the kneecap (trochlea). This surgery is the most effective option when the damaged tissue only affects the under-surface of the kneecap.
Because only part of the knee is replaced during patellofemoral replacement surgery, it has a quicker recovery time than total knee replacement surgery.
Your knee replacement surgery timeline
Getting knee replacement surgery can change your life for the better, but it’s also a major surgery. Understanding what to expect before, during and after surgery can help make the decision easier. Although the path to knee replacement surgery is a little different for everyone, here’s a general knee replacement timeline to help you know what to expect.
Step 1: Decide to seek treatment
The first step to a knee replacement is a straightforward one, making the decision to talk with a doctor. By the time you’ve made this decision, you’ve likely done your research, noticed
Step 2: Attend your knee surgery consultation
During your knee replacement consultation, your surgeon will talk with you about your health history and what you hope to get out of a knee replacement. In some cases, we may recommend imaging tests, such as an X-ray, to get a look at your joint.
Depending on your condition, your surgeon will work with you to determine if a knee replacement is the best course of treatment and which type is right for you. If your surgeon recommends a knee replacement, it’s also a good idea to talk with your health insurance provider about what’s covered.
Step 3: Prepare for knee replacement surgery
Before your surgery, the team at TRIA will help you prepare. Depending on your needs, surgery preparation might include physical therapy to improve the results of your surgery, pre-operative appointments and education around what to expect after surgery, knee replacement recovery and possible risks.
The amount of time it takes to
Step 4: Have your knee replacement surgery
It’s time for surgery! You’re in good hands with the expert orthopedic surgeons at TRIA. We provide industry-leading orthopedic care.
Knee replacement surgerynormally takes1-2 hours. After surgery, you’ll typically spend another 1-2 hours in the recovery room as you wake up from anesthesia before moving on to the next phase of your recovery.
Whenever possible, our patients return home the same day or the day after surgery. We may recommend assistive devices – crutches, walkers or canes – to make your recovery more comfortable. Other devices, including post-operative icing machines, can make some parts of your recovery plan easier.
Step 5: Follow your post-op recovery plan
Throughout your recovery, you’ll meet with your orthopedic surgeon, physical therapist and others from your care team to check how you’re healing. In most cases, you’ll have physical therapy sessions to strengthen your knee and help you have an optimal recovery.
Step 6: Move with comfort and confidence
After you’re fully recovered, you’ll be able to get back to the activities you love with less pain and better knee function. Our physical therapists, surgeons and orthopedic experts will be by your side during every step of your recovery.
Robotic-assisted total knee replacement
In some cases, robotic-assisted total knee replacement may be the best way to perform surgery. At TRIA, we currently use the
Robotic surgical assistants give your surgeon the real-time information they need to plan for and perform a total knee replacement that is based on your unique anatomy. A good implant fit is key to a full and comfortable recovery. During a procedure, ROSA and VELYS use live cameras and optical lens tracking to follow the exact position of the leg. If the leg moves even a millimeter, robotic assistants adjust to allow the most accurate placement of the implant.
With the latest surgical technology and contemporary rehabilitation programs, we help you recover as quickly and comfortably as possible. If robotic-assisted surgery is right for you, your surgeon will discuss it with you and can answer any questions you have.

Hotel Recovery Program
More of our patients are able to recover in their own homes. When that isn’t an option, recovering nearby in a hotel might be the best choice. With our Hotel Recovery Program, you’ll go to a comfortable hotel room after your surgery and we’ll bring the follow-up care directly to you.
Physical therapy after a knee replacement
Movement is key to a successful recovery, which is why your first physical therapy session will be as soon as possible after your knee replacement surgery.
During your
