  • Multimodal pain control, including Exparel, to decrease postoperative pain

Hip Replacement

The hip, a ball-and-socket joint, is one of the most important parts of your body when it comes to getting around. It allows you to walk, twist, get in and out of your car, climb stairs and simply bend down to tie your shoe. When your hip can't move like it used to, your daily life can be severely affected. Hip replacement surgery at POA is designed to relieve your pain, improve mobility, and increase your strength and coordination.

During total hip replacement, our surgeon will replace the ball at the upper end of your femur, or thigh bone, with a prosthesis made of state-of-the-art materials. The socket in your pelvic bone will be resurfaced as well. Damaged cartilage will be replaced, and your new joint will be locked into place in the precise location to restore your natural anatomy, ensuring that it moves normally. Your surgeon will choose the approach to the hip that best provides a long-lasting, stable joint that gets you back on your feet as quickly as possible. This can be done equally well from the front, side, or back of the hip.

Our team will review your medical history and perform a thorough evaluation to determine if hip replacement surgery is right for you. When needed, we will help you evaluate which type of implant and most up-to-date surgical technique is right for you, including:

  • The direct anterior minimally invasive, muscle sparing approach
  • The mini-posterior minimally invasive, muscle sparing approach
  • The posterior approach
  • A variety of traditional surgical approaches for more complex cases and hip revision surgery

Knee Replacement

The knee is the largest joint in your body. It is also a key player in nearly all of your everyday activities. So if your knees are debilitated from arthritis or injury, chances are your daily activities are severely limited. Total knee replacement at POA is designed to get you moving again, eliminate your pain, and improve your overall quality of life.

During total knee replacement, your surgeon will resurface your damaged knee and implant prosthesis. Your surrounding muscles and ligaments play a huge part in helping to support your new knee. Our team of orthopaedic surgeons perform many different types of knee replacement, including:

  • Unicompartmental: medial, lateral and patellofemoral
  • Posterior cruciate ligament (PCL) substituting
  • Posterior cruciate ligament (PCL) retaining
  • Patient-specific instrumented (PSI) partial and total knee replacement for added accuracy and customization
  • Rotating platform
  • Constrained hinge
  • Computer navigated knee replacement for added accuracy of within 1 millimeter or 1 degree on cuts. At POA, your doctor will work with you to choose the right design, fixation method and materials depending on the amount of bone loss, your surrounding ligaments, and other personal health factors. We use today's most proven minimally invasive and computer-assisted technology to cut down your recovery time and improve the accuracy of your knee replacement surgery.

Kinematic/Anatomic Knee Alignment

Kinematic, or anatomic as we call it, alignment in knee replacement simply means putting the replacement parts back so that it mimics the patient's natural alignment before the arthritic process began.

For the past 40 years, the majority of surgeons have replaced knees with a process called mechanical alignment, which has a goal of aligning the center of the hip, knee and ankle. Unfortunately, this only restores a patient's natural anatomy about two percent of the time. This means that in the majority of patients the ligaments that stabilize the knee no longer work at the length that was originally intended. They either end up too tight on one side and too loose on the other side, or the surgeon has to loosen the ligaments on one side of the knee in an attempt to "balance" the knee. In reality, what is happening is the surgeon is changing the way that the patient's knee works. This may explain why up to 20 percent of knee replacement patients across America are not satisfied with their new knee.

Anatomic alignment recreates each patient's individual anatomy and does not require releasing ligaments that stabilize the knee. Instead, the bone is cut in such a way that the ligaments are allowed to function normally without altering their length or tension on either side of the knee. This creates a more natural feel to the knee, a quicker recovery and a happier patient. POA surgeons use imageless computer-assisted navigation, which allows guided and personalized surgery and helps them execute the surgical plan with truly amazing precision. Our goal is to bring this technology and technique to surgeons across America, improving patient outcomes everywhere.

Why is this so important? Because lower leg alignment and patterns of arthritis vary widely from person to person, and a few degrees of variation in implant placement can lead to more successful outcomes and longer implant lifespans.

The benefits of Knee Alignment

  • A more natural feeling knee
  • Preservation of the correct joint line height and orientation, as well as a replaced knee that has the same appearance as the uninvolved knee
  • Quicker recovery times and return to normal activities
  • A greater range of motion

Our technique to create anatomic alignment allows for intraoperative planning adjustments and ensures that each patient has the knee positioned optimally to allow the ligaments to function normally.

Our orthopaedic specialists will review your medical history and perform a thorough evaluation to determine if kinematic knee alignment is right for you.

Shoulder Replacement

Shoulders are complicated. As the most mobile joint in your body, the shoulder works with a vast network of cartilage, bones, muscles, and ligaments to bear the brunt of your hard work. As an intricate body part, the list of possible shoulder ailments is extensive, from osteoarthritis to rotator cuff injuries. And when your shoulder is in pain, your whole body can feel it, too.

The good news is that your shoulder is in excellent hands at POA. Our surgeons have the most experience in total shoulder replacements in the area and were the first in the region to offer reverse total shoulder replacement.

During shoulder replacement surgery, your surgeon will replace or cap the damaged portion of your upper arm and shoulder bone with a state-of-the-art prosthesis. We use the most current technology to get precise and accurate results with the least amount of pain and shortest recovery time possible.

Reverse Shoulder Replacement

Reverse shoulder replacement is an option for patients with major rotator cuff tears and chronic shoulder arthritis. POA is one of a select group of U.S. practices whose surgeons are highly experienced in this newer, complex shoulder procedure. During the procedure, your surgeons will reverse your shoulder's mechanics by inserting a highly specialized implant. In short, the ball-and-socket shoulder becomes a socket-and-ball shoulder. The results can be astonishing – bringing movement back to seriously injured shoulders, eliminating pain and greatly improving shoulder mobility.

Reverse shoulder replacement is not right for everyone, but in some cases it's exactly what is needed. Our shoulder surgeons will review your medical history and perform a thorough evaluation to determine if shoulder replacement surgery is right for you.
