Total Joint Replacement


Receive exceptional care from a renowned orthopedic team

The Total Joint Replacement Program at Tufts Medical Center in Boston uses advanced surgical and non-surgical techniques to eliminate or relieve your hip and knee pain. Whether you have severe arthritis or another painful joint disorder, you can count on our orthopaedic team to get you moving again.

Surgical expertise is what matters most

Every year, Michael Baratz, MD and Jeffrey Zarin, MD perform hundreds of total joint replacements, a mark of his skill and experience that also places our program in the high-volume category for these surgeries. Drs. Baratz and Zarin are skilled in the latest reconstructive and joint replacement techniques, including direct anterior hip arthroplasty, and minimally invasive arthroscopic surgery.

Our orthopedic surgeons treats many people who have from multiple illnesses or serious neuromuscular disorders, such as paralysis following a stroke. As a result, doctors throughout Greater Boston entrust us with patients who have severe conditions. They also regularly refer people who need joint replacement revision, a high-risk procedure because of its potential for dangerous complications.

Should total joint replacement be your best treatment option, you will be in excellent hands. Our joint surgeons personally performs all the procedures at the Total Joint Replacement Program.

Is total joint replacement right for you?

Thousands of total joint replacements are performed in the United States every day. Today’s surgical techniques are extremely advanced, and joint implant materials are very durable.

Before we consider total joint replacement surgery, we typically explore conservative, non-operative treatments to preserve your natural hip. Decisions about surgery are made only after a health evaluation and in-depth conversations between you and our physicians.

Educating you and your family about your condition and options is an important part of our mission. You can learn more by reading our Total Joint Replacement FAQs.

If you’re planning to have a joint replacement, we encourage you to attend our Total Joint Replacement Workshop. The workshop is a unique event where we answer all your questions and cover everything you need to know before you have surgery.

Surgical Alternatives to Total Joint Replacement

In keeping with our approach to preserving the natural hip whenever possible, we regularly perform other procedures for hip and knee conditions, such as:

  • Arthroscopic procedures for a wide range of problems, which can preserve more natural bone and tissue and requires smaller incisions
  • Anterior hip replacement
  • Hip resurfacing
  • Partial knee replacement
  • Repairs of advanced labrum tears of the hip
  • Decompression of femoral acetabular impingement (FAI)

Total Joint Replacement Workshop

To educate you and your family, Orthopaedics offers a unique event, the Total Joint Replacement Workshop. The workshop is located on the downtown Boston Tufts Medical Center campus runs approximately 90 minutes.

The workshop covers your:

  • Pre-operative testing
  • Post-operative course of treatment
  • Rehabilitation and discharge

At the end of every workshop, we hold an in-depth Question-and-Answer session.

During the session you will have the opportunity to hear a clinician from Orthopaedics, a physical and/or occupational therapist, an orthopaedic nurse, a nurse case manager and a representative from our blood bank. All of these people are integral members of your multidisciplinary, Total Joint Replacement team.

Conditions We Treat

We treat the complete range of hip and knee injuries and disorders, including:

  • Avascular necrosis of the hip
  • Advanced arthritis
  • Osteoarthritis
  • Rheumatoid arthritis
  • Perthes disease
  • Slipped capital femoral ephysis
  • Femoral acetabular impingement (FAI)
  • Developmental dysplasia of the hip (DDH)

Research + Clinical Trials

Drs. Baratz and Zarin lead a research team that explores the effectiveness of new surgical techniques, joint implants and total joint replacement systems. Many of the team’s investigations stem from patients’ questions about total joint surgery and implants and how they affect outcomes after surgery.

Along with our joint registry, which tracks outcomes of people who have had total joint replacements at our program, we have been able to improve the procedures we do today and our knowledge – which we always pass along to you, your family and caregivers.

We are very active in running clinical trials, mostly in part with the makers of joint implants and implant systems. Our work already is paying dividends and can benefit you or a family member in the future if either of you need hip or knee replacement or revision.
