What is Revision Total Hip Replacement?
A hip replacement surgery is a standard procedure that many people undergo. It involves a prosthesis referred to as a ball and socket that must be assembled both before and during the operation. It mimics the function of the human hip joint throughout the life of the prosthesis. However, the prosthesis is prone to different types of mechanical and biological defects. If the defect occurs post-surgery, then another operation known as a revision Hip Replacement in Koramangala, Hsr Layout, Btm Layout, Bellandur, Bangalore might be necessary to deal with the defects.
When to consider a revision hip replacement?In older patients who undergo a total hip replacement, the prosthesis has a life of around 15-20 years which can last them for a lifetime depending on their age. However, if the first hip replacement surgery is done at a young age and the patient is physically active, they might need one or more revisions of hip replacement surgery. Preoperative exams of those who need a revision hip replacement are more meticulous than those who undergo it for the first time. For revision surgery, X-Ray projections, CT Scans, or MRI might be required to locate the prosthesis position, parts that need replacement, and bone loss around the failed implant. If the surgeon has a suspicion of infection around the old prosthesis, they might suggest some blood tests as well.
ReasonsThe revision hip replacement surgeries are not performed frequently. Following are the reasons for revision hip replacement surgery-
- Frequent dislocation of the implant
- Mechanical defects like wear and tear of the prosthesis
- The alignment and fitting of both the ball and socket
- The force created by stronger muscles and ligaments surrounding the hip joint
