Revision Single Knee Replacement

A revision single knee replacement surgery is a procedure that replaces and repairs the prosthetic implant that is already placed in the knee. This surgery, also known as reoperation, involves the removal of the original prosthesis and the insertion of a new implant. Sometimes, knee revision is recommended for only a single knee, while in other cases, a complete replacement of the prosthesis is required.

Furthermore, there are various reasons for knee implant failure that need to be discussed here.

Understanding the reasons to have revision single knee replacement

Some of the common reasons that is also an indication of revision single knee replacement include:

InfectionConstant and recurrent infection in the knee joint that affects the initial knee replacement surgery may need a surgery to remove the infected prosthesis and to repair the infection.

Mechanical failureFailure in the implanted prosthesis such as loosening wear, wear and tear of the prosthesis, instability are all the causes of mechanical failure of the initial knee replacement, that requires revision or reoperation.

Implant displacementDisplacement of the prosthesis can cause component malposition, soft tissue imbalance or trauma that may need revision surgery.

Component fractureLeg fracture may affect the component that leads to component failure. This can happen due to trauma, injury, stress. This may need revision surgery.

Pain and dysfunctionRegular chronic pain, limited range of motion, instability, limited function that cannot be treated with non surgical treatment may require revision surgery.

Conditions that treat revision single knee replacement

Common conditions that revision single knee replacement treat include:

Infection

Implant loosening

Implant dislocation

Mechanical failure

Regular pain

Dysfunction

Limited function

Instability

Types of revision single knee replacement

Simple revisionAs like its name, only some components are replaced with original knee components.

Complex revisionThis surgery is a very complex procedure that completely removes and replaces all the components of the knee replacement.

Implant exchangeThis is the exchange of implants with the original or previous one.

Bone graftingTwo types of bone graft are used to fulfil bone loss. The type of bone graft is autograft (bone tissue made of their own tissue) and the other is allograft (bone tissue received from the donor or bone bank). This procedure is performed to rebuild the damaged bone.

InfectionRevision surgery treat infection, this surgery helps to remove the infected tissue, clear the joint and insert antibiotics beads that treat infection.

Patellar resurfacingProblems with the patella (knee cap), revision surgery involves resurface or replacing the patellar prosthesis.

Procedure to perform single knee replacement surgery

The revision single knee replacement surgery is more difficult and takes longer than usual than initial knee replacement surgery.

Starting with giving anesthesia to the patient to ensure the patient feels no pain during the surgery.

The surgeon makes an incision, same like initial knee replacement surgery but this time the incision might be longer to get better access to the implant.

The surgeon performs the removal of existing components that may consist of cement or screws that are used to fix the prosthesis.

Understanding the current condition if there is a certain bone loss, the surgeon may require bone grafting to fulfil the need of the lost bone.

The surgeon places new implant components that consist of new femoral prosthesis, tibial component, or patellar component. The fixation of these components are done with cement or screws.

Finally the component is positioned at the required place, the surgeon closes the incision with stitches and covers it with bandages.

Cost of revision single knee replacement in India

The cost of revision single knee replacement surgery in India is affordable and convenient. As all the facilities and services are provided by the top orthopedic hospitals in India. Although facilities like airports, stays, no language barrier and more are the facilities that international patients approach for. Also the total cost of the treatment may vary depending upon the condition of the patient. Some other factors such as choice of hospital, selection of the top orthopedic surgeons in India, type of surgery can vary the cost.

India is among the leading countries to serve for medical care.

Summary

A revision single knee replacement surgery is a procedure that replaces and repairs the prosthetic implant that is already placed in the knee.

Sometimes, knee revision is recommended for only a single knee, while in other cases, a complete replacement of the prosthesis is required.

India is one of the leading countries providing exceptional medical care.
