Knee and Shoulder Replacement Surgeries Can Relieve Pain, Return Range of Motion
Dr. Kareem Sobky and Dr. Mark Tuttle, two OrthoONE physicians at Presbyterian/St. Luke’s Medical Center, specialize in active lifestyle orthopedics, including total hip, knee and shoulder joint replacements and sports surgeries, like knee and shoulder arthroscopy. They use the most innovative methods to help people get back to living active lives, unrestricted by painful orthopedic injuries or conditions.
What’s the most cutting edge technology for knee replacements?
Dr. Mark Tuttle: The newest cutting-edge trend in knee replacement technology is a cement free, press fit knee replacement. Rather than using cement to fix the implant to the end of the bone, we biologically fix the implant. With a press-fit knee, we use a porous metal joint, which allows your body to incorporate the implant. Basically, the bone grows into the microscopic pores on the roughened metal surface, resulting in what we call biological fixation.
A press-fit knee is superior to using cement because it won’t de-bond over time and cause the implant to loosen, which in a recent study was the most common cause of knee replacement failure. Press-fit knees are associated with better outcomes and less revision surgery. We also use computer navigation for our knee replacements so we can be as minimally invasive as possible. Most people are good candidates for this type of surgery, which has a fairly fast recovery — by the three month mark, we expect you’ll be back outside enjoying the activities you love to do. My best advice for patients who are facing a knee replacement in the near future is to find an orthopedic surgeon who does a high volume of press-fit knee replacements and utilizes computer navigation to achieve as perfect alignment of the knee possible.

What are the two types of shoulder replacement surgery you offer?
Dr. Kareem Sobky I offer two types of shoulder replacement surgery: Anatomic Total Shoulder Replacement and Reverse Shoulder Replacement. Chronic shoulder pain can be unbearable for some people. When the shoulder cartilage wears out and becomes painful and restrictive, the only reliable solution is to replace the worn surfaces with artificial and durable materials. With a Total Shoulder Replacement, all or part of the glenohumeral joint is replaced by a prosthetic implant. This type of surgery requires the muscles and tendons around the shoulder to be intact. A total shoulder replacement is often done as an outpatient surgery or with just an overnight stay when indicated.
A Reverse Shoulder Replacement, which I consider to truly be a revolutionary orthopedic surgery, is a good option for people who have arthritis of the shoulder and a rotator cuff tear or severe shoulder deformity. This surgery is also a good option for people who have a rotator cuff tear that is too large to repair. A Reverse Total Shoulder Replacement relies on the deltoid muscle (rather than the rotator cuff) to move the arm. This reverse prosthesis helps to restore some range of motion to the shoulder and provides a lot of pain relief for many of my patients.
