Knee Replacement


ROSA Knee Replacement

UC San Diego Health's orthopedic surgeons are the first and only in San Diego to offer customized knee replacements with the ROSA knee system — for a faster recovery and more natural feeling knee.

Talk to one of our surgeons about whether a ROSA knee replacement is right for you.

At UC San Diego Health, you find surgeons with expertise and experience in total and partial knee replacement (also called knee arthroplasty). With a full spectrum of surgical options available to you, your surgeon can personalize your care plan to your health, lifestyle and individual preferences.

UC San Diego Health is repeatedly ranked among the nation's best in orthopedic care by U.S. News & World Report.  We are also a Blue Distinction Center recognized for our treatment expertise and better overall patient results for knee replacement, as well as a designated Center of Excellence for orthopedic care by Optum. This means you'll receive expert, safe and cost-effective care.

Customized Knee Replacements

Your surgeon is specially trained to make sure your knee replacement is customized to fit your joints and bones. That customization — using the latest in imaging technology, three-dimensional modeling and surgical guides, and proven components — means better balance and alignment.  With better fit and alignment, you may experience greater comfort, more natural knee movement and a potentially longer-lasting prosthetic knee. 

Our muscle-sparing surgical techniques also help speed your recovery by reducing impact to surrounding muscles and soft tissues. We understand the importance of pain management and post-surgical rehab to your recovery. Your rehab begins shortly after surgery with highly trained physical therapists.

Options for Total and Partial Knee Replacement 

Each person's knee is different. This is why we offer several surgical options for knee replacements to tailor care to your injury and health. Each surgical approach has benefits for the right surgical candidate. Your surgeon can discuss what option is most appropriate for you. Knee surgeries we offer include:

  • Medial unicompartmental replacement (replacement of the inside part of the knee)
  • Lateral unicompartmental replacement (replacement of the outside part of the knee)
  • Patellofemoral unicompartmental replacement (replacement of the front part of the knee)
  • Complex revision knee replacement  

ROSA Knee System

ROSA, which stands for Robotic Surgical Assistant, is an advanced technology that helps your surgeon perform total knee replacements with greater precision and accuracy.

More specifically, ROSA enables your surgeon to create a three-dimensional model of your knee using X-rays. This model lets your surgeon plan and virtually perform your knee replacement even before entering the operating room. During the procedure, your surgeon uses ROSA to monitor your leg alignment and ligament balance. This information helps to recreate the most functional knee for your particular anatomy. 

In essence, ROSA enables a more personalized and precise knee replacement, allowing you to return to an active lifestyle without pain.

Knee Replacements without a Hospital Stay

With less invasive surgical techniques and better anesthesia, some patients may be able to go home within several hours of surgery. How well you are moving around before surgery — not age — is the best predictor for how quickly you will recover from surgery. If you are interested in an outpatient knee replacement, talk to your surgeon about whether it is a good option for you.

Recovery and Rehabilitation

Your care team works closely with you before and after surgery to educate you about your surgery and the recovery process, including pain management. Physical therapy is a key to allowing you to return to a more active lifestyle. UC San Diego Health orthopedic rehab specialists work with you one-on-one to develop an exercise routine that will help you regain knee function, strength and stability.
