Knee Replacement Q & A

Why Are Knee Replacements Needed?

Knee replacements are one of the most common and most successful surgeries performed in the United States today. Most physicians will provide more conservative forms of treatments for knee injuries during the early stages of care and recommend knee replacement if those less invasive measures are not effective. Injuries to the knee or degenerative conditions such as arthritis often lead to the need for knee replacement. Knee replacements are an effective treatment for patients who are unable to carry out normal day-to-day activities such as going up and down stairs, walking, or trouble sleeping due to pain, even with the application of other care modalities. If a patient has bone-on-bone arthritis where all of the cartilage and cushion in the knee joint has worn away, knee replacement surgery may be the only effective treatment to provide sustainable pain relief.

What Happens During Knee Replacement Surgery?

Dr. Zhao uses innovative and state-of-the-art surgical techniques including MAKOplasty® and robotic surgery to perform knee replacements. These surgical procedures allow a greater precision resulting in better patient outcomes. MAKOplasty® enables customized implant designs and surgical planning specific to the unique needs and anatomy of each individual patient. It provides a tactile technology complete with 3D visualization for controlled resurfacing. Patients with tibiofemoral/patellofemoral disease, as well as osteoarthritis, also benefit from the multicompartmental resurfacing implants provided by this breakthrough technology as an alternative to other treatments. The accurate implant alignment and placement help patients to regain mobility and an improved quality of life.

How Do I Take Care of My New Knee?

Following surgery, you will follow a physical therapy regime to rebuild your strength in and around the joint. You will have regular follow-up appointments with Dr. Zhao to monitor your recovery and to make sure you are healing correctly. You may need to take some painkillers during the days directly following surgery.


MAKOplasty is a surgical procedure using Robotic Arm Interactive Orthopedic System for partial or total knee replacement. MAKO is a procedure designed to relieve the pain caused by joint degeneration due to osteoarthritis (OA) in the knees. The Mako technology provides your surgeon with a patient-specific 3-D model to pre-plan your partial knee replacement. During surgery, your surgeon guides the Mako robotic-arm based on your patient-specific plan. By selectively targeting the part of your knee damaged by OA, your surgeon can replace the diseased part of your knee, place the implant based on your exact anatomy while helping to spare the healthy bone and ligaments surrounding it.

Potential advantages include shorter hospital stay, less scarring, and faster recovery and return to an active lifestyle
