Knee Replacement Surgery

Knee replacement surgery, also known as total knee replacement or arthroplasty, can help relieve pain and restore function in severely damaged knee joints. During the procedure, the damaged bone and cartilage of the femur, tibia, and patella resurface, cutting the damaged areas and replacing them with an artificial joint made of metal alloys, high-quality plastics, and polymers.

The orthopedic surgeon will be the person that can determine whether a knee replacement is right for you. The surgeon will assess your knee's range of motion, stability, and strength.  

There are several reasons for the knee joint to be damaged. There are various types of arthritis, among which we can find, Osteoarthritis, Rheumatoid arthritis, or Traumatic arthritis.

In all these cases the goal when getting knee surgery is the same, to relieve the knee pain, which usually we have not been able to control using any other treatment.

Duration of hospital stay: It requires to stay at the hospital several days (likely a couple of days), depending on the case

How Does It Work?

Step 1: Knee incision

An incision is made in the front of the knee, usually 4 to 10 inches long. In this way, the surgeon can access the kneecap (kneecap)

 

Step 2: Rotating the kneecap (patella)

For the surgeon to gain visibility and access to perform the surgical procedure, the surgeon will rotate the kneecap

 

Step 3: Preparing the thighbone (femur)

The damaged area is measured and carefully cut with special equipment. The end of the femur is modified to fit the first part of the artificial knee

 

Step 4: Implanting the femoral component

The femoral component joins the recently cut and adapted area of your femur

 

Step 5: Preparation of the tibia

Following a procedure similar to that of the femur, the damaged area of ??the tibia is removed and replaced on the surface to fit the artificial tibial component

 

Step 6: Implanting the tibial component

Two implants must be done during this step, the first one is called the tibial tray. When the tray is in place, the surgeon will fit a polyethylene insert that lies between the tibial tray and the artificial femoral component. This last part is the one that supports your body while using your knee

 

Step 7: Adjusting the kneecap (patella)

If the patella needs adjustment to fit with the rest of the implant, it gets adjusted

 

Step 8: Finalize the procedure

Before finalizing the procedure, the surgeon will ensure that the implant works correctly, observing the positioning, size, and alignment. Once this review is done, the surgeon will close the incision and prepare it for recovery.
