ROSA® Robotic Knee Replacement System

GW Hospital is the first in Washington, D.C. to use the ROSA® (Robotic Surgical Assistant) Knee System for total joint replacements. The ROSA system assists surgeons and enables them to perform procedures with greater accuracy, tailoring the fitting of the implant to your unique anatomy. The surgeon uses data collected before and during the procedure to improve the precision of the fitting. This helps improve comfort and your overall experience after the surgery.

This is a minimally invasive surgery that can result in less scarring, a quicker recovery and less pain.

Joint Replacement Rehabilitation Program

The joint program focuses on optimizing patient readiness for and recovery from joint replacement surgery. Patients will be seen prior to surgery to review how best to prepare for surgery and what to expect when they get home from the hospital. Patients will be on a formalized surgeon-therapist collaborative protocol for postoperative rehabilitation. The primary goal is to restore independent function and optimize mobility as quickly as possible.

Knee conditions


Osteoarthritis, also called degenerative joint disease, occurs when the cartilage in your joints wears down, causing your bones to rub together. It is the most common form of arthritis and can cause pain, swelling and reduced motion in your joints.

Knee effusion

A knee effusion, or water on the knee, occurs when excess fluid builds up around the knee joint, causing swelling, pain and stiffness. This can be caused by arthritis or injury.

Meniscal tear

The meniscus is the cartilage that cushions the knee. A meniscal tear can occur when you twist or over-flex your knee, or quickly stop and change direction.

Ligament strain or tear

Direct contact to the knee or changing direction rapidly while running can cause a knee ligament to stretch or tear. This can affect any of the four ligaments in the knee, which are the anterior and posterior cruciate ligaments (ACL and PCL) and the medial and lateral collateral ligaments (MCL and LCL).

Patellar subluxation

A kneecap dislocation or sublaxation can occur when the knee is hit from the side or when it is suddenly twisted or turned. Swelling and pain are the result.


Bursitis occurs when a bursa, a small sac filled with lubricating fluid that serves as a cushion between a bone and other moving parts, becomes inflamed. Pain, swelling, and stiffness are likely to occur.

Baker’s cyst

A Baker's cyst occurs when joint fluid builds up and leads to the formation of a cyst behind the knee. This is normally caused by meniscal tears, cartilage injuries, or arthitis.

Rheumatoid arthritis

Rheumatoid arthritis occurs when your immune system mistakenly attacks the tissues that line your joints, causing pain, swelling, stiffness and loss of function in your joints. Over time it can cause damage to bone and cartilage in the joints.

*Individual results may vary. There are risks associated with any surgical procedure. Talk with your doctor about these risks to find out if minimally invasive surgery is right for you.​
