When you undergo total hip replacement surgery at Onvida Health, your surgeon will replace the damaged bone and cartilage with prosthetic components by using one of the following procedures, based on your specific situation:

Anterior Approach – For this minimally invasive procedure, the surgeon accesses the hip joint from the front of the upper thigh and uses smaller incisions and more specialized instrumentation to minimize muscle and tendon disruption. This results in a less traumatic surgical experience for the patient, a shorter hospital stay and quicker recovery. Anterior hip replacement allows patients to immediately bend their hip freely and bear full weight when comfortable.

Posterior Approach – This approach to hip replacement has been used in the United States for many years and provides the surgeon with a good view of the hip structure to aid in the placement of the implants. To perform this procedure, the surgeon will make an incision at the back of the hip and cut through muscles and other soft tissue in order to access the hip joint.

Partial Knee Replacement – In this minimally invasive procedure, the surgeon will make a small, 2-3 inch incision and remove only the diseased portion of the knee and replace it with an artificial component called an implant or prosthesis. Partial knee replacements are performed when only one or two sections of the knee need to be replaced, either the inside (medial) part of the knee, the outside (lateral) part, or the kneecap. Compared to total knee replacement procedures, the benefits of partial knee replacement are a smaller incision and scar, less blood loss, a reduced hospital stay, decreased pain and a quicker rehabilitation/recovery time. Our surgeons use advanced technology called the MAKOplasty® Robotic Arm to perform this procedure. Before surgery, a computed tomography (CT) scan is taken, which the RIO system uses to create a virtual 3-D anatomical model of your knee. This model allows the surgeon to plan the placement and alignment of your knee implants prior to surgery. Once the surgical plan is finalized, it is programmed into the RIO, which creates a “safety zone” for bone removal. During surgery, the surgeon controls the robotic arm and is assisted by computer imaging that helps ensure precise placement of the implant. Due to this precise placement, there may be less pain for the first eight weeks after surgery as compared to manually-placed implants.

Total Knee Replacement – This procedure involves replacing the damaged bone and cartilage in the knee joint with components made of ceramic alloys and plastic. The benefits of a total knee replacement are reduced joint pain, increased leg strength, improved quality of life and years of easier movement.

Reverse shoulder replacement has revolutionized the treatment of massive rotator cuff tears. The unique procedure reverses the anatomy of the shoulder so that the ball is attached to the shoulder blade and the socket is placed on top of the upper arm bone. By reversing the normal anatomy, the deltoid muscle, one of the stronger shoulder muscles, is given the ability to raise the arm.

The shoulder system used by the surgeons at Onvida Health is the next generation in reverse shoulder prosthesis, offering unmatched flexibility. Most candidates for shoulder replacement are in extreme pain, have almost no shoulder flexibility and have tried various treatment options, oftentimes including primary shoulder replacement. Reverse shoulder replacement is designed to alleviate their pain and improve mobility so they can return to performing the activities of daily living.
