A revision total hip replacement, also known as revision arthroplasty, is a surgical procedure performed to replace a previously implanted artificial hip joint with a new one. This type of surgery becomes necessary when a primary total hip replacement (the initial replacement of a damaged hip joint) fails or becomes compromised due to various reasons, such as wear and tear, infection, instability, or loosening of the implant components over time.

Revision total hip replacement involves more complexity than the initial procedure because the surgeon needs to address existing issues, remove the old implant components, address bone loss, and implant new components effectively. The goal of revision surgery is to restore proper joint function, alleviate pain, and improve the patient’s quality of life.

The procedure typically involves the following steps:

• Removal of Old Components: The surgeon removes the old implant components, which may include the acetabular cup (socket), femoral stem, & any associated hardware.
• Bone Preparation: Any damaged or compromised bone tissue is removed, & the remaining bone is prepared to receive the new implant components. Bone grafts or special materials might be used to fill in areas of bone loss.
• Implant Placement: The new implant components are positioned & anchored securely to the bone. This may include a new acetabular cup, femoral stem, & sometimes additional components such as bone augments or metal wedges to address bone loss.
• Soft Tissue Repair: The surrounding soft tissues, including muscles, tendons, & ligaments, are repaired and reattached to ensure joint stability.
• Closure: The incision is closed, and the surgical site is dressed and bandaged.

Recovery from revision total hip replacement can be more challenging compared to primary total hip replacement due to the complexity of the procedure & potential bone loss. The patient will likely undergo a comprehensive rehabilitation program to regain strength, mobility, and function. Physical therapy plays a crucial role in helping patients recover and adapt to their new hip joint.

It’s important to note that revision surgery carries additional risks & considerations compared to primary joint replacement. Factors such as infection, bone loss, & the patient’s overall health can impact the outcome of the surgery. Patients considering revision total hip replacement should discuss their options and potential outcomes with a skilled orthopedic surgeon to make informed decisions about their treatment.
