WHY DO I NEED A REVISION?

Revisions are recommended for several reasons. If a prosthesis has been in place for a long time, the bearing surface may have worn, requiring a simple exchange. This is the easiest type of revision with the shortest recovery period, as the critical components are not changed. Loosening of the components (either the socket or stem) can occur independently or simultaneously, and require removal of one or both. Depending on the difficulty of the removal, the recovery can be short (six weeks) or long (six months). The hip components can dislocate. This may be remedied with a single “reduction” maneuver, but if this becomes chronic, revision surgery may be necessary. Finally, an infection around the prosthesis may require removal of the prosthesis. Once the infection has resolved, new components can be placed.

ARE THE COMPONENTS THE SAME?

The components are very similar. This typically involves a larger diameter socket and a longer stem or rod. For enhanced fixation, screws are commonly used for increased contact with the native bone. Finally, augments, which are metallic bone substitutes, can be used to rebuild any prior bone loss.

IS THE RECOVERY SIMILAR TO PRIMARY HIP REPLACEMENT?

Functional rehabilitation is similar in that often the “anterior approach” can be utilized enabling early and quick recovery. Specific hip limitations or precautions are sometimes needed to allow the soft tissues to heal. Usually, full weight-bearing is allowed, with the exception of revisions that necessitate osteotomies or bone cutting for implant removal. In these uncommon cases, a period (typically six weeks) of partial weight-bearing is required to allow the bone to heal properly. The usual time for resolution of most of the symptoms is three to six months.

Journey II XR Bi-cruciate Retaining Knee System

The XR is a new concept in knee replacement surgery. Traditional knee replacement designs did not allow for the preservation of the cruciate ligament (ACL), which in the normal knee is responsible for anterior/posterior stability. Without this knee ligament, traditional knee replacement designs have not been kinematically (how the knee functions) normal.

Specifically, the femur (thigh) bone will translate or shift anteriorly on the tibia (leg) bone causing pain and instability in activities such as stairs, squatting or stooping. This has been shown by the fact that on average only 15 % of total knee replacement patients can squat comfortably.

The XR knee system features an anatomically shaped femur (identical to the traditional Journey II knee options) and a new U-shaped tibial component with a mid section of preserved bone (where the ACL/PCL ) attach. This U shape allows for appropriate resurfacing of the worn tibial cartilage without forcing resection of these critical ligaments.

The technique is identical to traditional knee replacement steps and, therefore, does not add time or difficulty to the standard procedure. Our early experience has shown excellent results with respect to patient outcomes, satisfaction and return to activities.
