Hip & Knee Revision
During hip or knee replacement surgery, the joint is replaced with a prosthesis (implant) made of metal, plastic, and/or ceramic components. While the majority of total hip or knee replacements are successful, they may not be permanent, as problems can develop over the long-term.
Although a prosthesis is either cemented into position during the initial joint replacement surgery or implanted in such a way that the bone is expected to grow into the surface of the prosthesis, it may loosen from the underlying bone and cause pain due to any number of factors.
Reasons for Hip or Knee Revision
- High-impact activity
- Excessive body weight
- Wear of the plastic spacer between the two metal components of the implant
- Osteolysis, a condition in which the bone surrounding the prosthesis deteriorates, making the implant lose or unstable
In addition to an implant becoming loose, other circumstances that may warrant a hip or knee revision include infection within the artificial joint, recurrent dislocation within the hip or ligament instability within the knee, or a fractured bone around the implant.
It is not unusual for younger patients who have undergone hip or knee replacement to outlive the life expectancy of their artificial hip or knee. When that is the case, a revision procedure may be necessary to replace the original components.
In the Coral Gables-Miami area, Dr. Carlos J. Lavernia routinely performs hip and knee revisions. Many orthopedic surgeons choose not to perform joint revision surgery because it is much more complex and time-consuming than a primary joint replacement. The risk of complications or chronic pain following revision surgery is also higher. However, Dr. Lavernia’s patients enjoy a high success rate following revision hip or knee surgery.
Often, revision surgery only involves the replacement of a few components of the prosthesis. However, if the whole prosthesis needs to be removed or replaced, the bone around the knee or hip may need to be rebuilt with a bone graft or augments (metal pieces). Since damage to bone and soft tissue make it difficult to use standard implants, Dr. Lavernia usually uses specialized implants designed to compensate for the damaged bone and soft tissue.
