What are the components of a TKA?

What are the components of a TKA?

The standard primary TKA is comprised of a cemented Cobalt-Chrome femoral component, a polyethylene liner and a titanium tibial baseplate, and polyethylene patellar button (if the patella is resurfaced).

What is the difference between PS-TKA and CR-TKAs?

The PS-TKA posterior rollback is only 80% of what is observed in the native knee. Yet in comparison to CR-TKA designs, it is generally considered to drive greater and more reliable rollback. Importantly this does not appear to influence functional outcome or even range of motion.

What are the stages of TKA in Navio™?

The NAVIO™ Surgical System’s TKA application can be broken up into the following stages: 1. Patient and System Setup 2. Surgical Preferences 3. Bone Tracking Hardware 4. Registration 5. Implant Planning 6. Bone Cutting 7. Trial Reduction 8. Cement and Close This surgical techniqueguide is separated into the same stages for clarity.

What are the disadvantages of CR TKA?

Disadvantages. The CR-TKA is more challenging to balance because PCL tension enters the equation when balancing the flexion and extension gaps. The CR-TKA is also more challenging to balance with larger knee deformities (varus > 10°, valgus > 15°).

The prosthesis generally comprises three components: the tibial component (to resurface the top of the tibia or shin bone), the femoral (thigh bone) component (to resurface the end of the thighbone), and the patellar component (to resurface the bottom of the kneecap that rubs against the thighbone).

How much blood loss in knee replacement?

The mean intra-operative blood loss was 220 ml (±115.6) and the average post-operative drainage was 443 ml (±160.9). The total measured blood loss thus amounted to 663 ml (±209.7) in a primary uncomplicated TKR. The mean drop in Hb was 2.39 g% (Table 2).

How is a TKA done?

The doctor will make an incision in the knee area. The doctor will remove the damaged surfaces of the knee joint and resurface the knee joint with the prosthesis. The knee prosthesis is made up of metal and plastic. The most common type of artificial knee prosthesis is a cemented prosthesis.

What is B TKA?

Simultaneous bilateral total knee arthroplasty (BTKA) is often performed to treat patients with disabling arthritis of both knees. Its use compared with staged procedures remains controversial.

Is knee replacement a bloody surgery?

Bleeding during and after surgery is normal. In rare cases, a person may lose too much blood during the procedure and need a transfusion. Sometimes, after surgery, blood can pool under the skin and cause swelling.

Is knee replacement high bleeding risk?

Patients undergoing elective hip or knee arthroplasty are at risk for bleeding and bleeding-associated complications.

What happens during a TKA?

What is TKA used for?

The primary indication for total knee arthroplasty (TKA; also referred to as total knee replacement [TKR]) is relief of significant, disabling pain caused by severe arthritis.

What is bilateral TKA?

Bilateral total knee arthroplasty (TKA) in a one-stage surgical procedure has the advantage of a single hospital stay, shorter rehabilitation, and reduced patient management costs. However, until now the use of this strategy has been limited by the fear of a higher rate of perioperative complications.

Is bilateral knee replacement recommended?

When severe arthritis affects both knees, a doctor may suggest double knee replacement surgery. However, more risk is involved with this type of surgery, so it’s typically only recommended to those who are: physically fit. in overall good health.

What is the newest technology in knee replacement?

This latest advancement in joint replacement surgery transforms the way knee replacements are performed. “The Mako system is a revolutionary tool to help joint surgeons be more precise in placing implants to achieve the most appropriate, balanced position possible,” explained orthopedic surgeon Harold Cates, MD.

What is the main body system affected by TKR?

Knee replacement surgery removes a diseased knee joint and replaces it with an artificial joint (prosthesis). The most common reason for this operation is severe osteoarthritis, which causes relentless pain, joint deformity and mobility problems.
