5/24 Knee Test

1

Which side of the knee acts as a ball & socket joint?

1

What are the 3 axes of the Knee

1

There are 3 joints of the knee. Medial tibiofemoral, lateral and the .

1

What is the degree difference roughly between the anatomical axis and mechanical axis of the femur?

1

What is the correct term to label this knee issue?

1

The mechanical axes is right through the center of the femur.

1

What muscles make up the quadriceps?

1

The patella tendon is also called the patella ligament.

1

The patella will bring on more tension to the quadriceps

1

The keep the tension needed for the quads the patella will articulate or slide in what direction during flexion?

1

In the past the femoral condyles were believed to be shaped before it was discovered that they in-fact were more circular.

1

What does the femoral roll back increase?

1

Which is a correct description of tibia shape?

1

The shape of the tibia helps with pivot.

1

When standing up straight (muscles extended), the tibia will externally rotate. What do you call this arc of motion?

1

When standing up straight (muscles extended), the tibia will externally rotate. When the knee starts to flex the tibia will internally rotate. If the bones and ligaments are doing the work what kind of motion is this?

1

Is the Functional arc of the knee an active or passive motion?

1

In the deep flexion arc the tibia internally rotates with reference to the femur. The femur also translates anteriorly.

1

What is caused by the breakdown of cartilage between joint bones?

1

How would you described Rheumatoid arthritis?

1

The granulation tissue (thickened synovium) that forms in RA patients is called .

1

The materials used for TKA implants are pretty standardized. Tibial components are ( titanium, cobalt chrome, polyethylene, stainless steel ). Tibial insert and patellar components are ( titanium, cobalt chrome, polyethylene, stainless steel ). Lastly the femoral component is ( titanium, cobalt chrome, polyethylene, stainless steel ).

1

Which implant component would you NOT use medical cement.

1

If you use two different metals in the body and they come in contact with each other they will react to each other.
Ionization and oxidation is this process.

1

Cobalt chrome is an . This means it contains a combo of three different metals.

1

Bone cement (PMMA) appears radiolucent on x-ray, so you will not see it on an image.

1

What is relied on in a press fit implant for stabilization.

1

Which are the two products that are press fit implants made by Zimmerman and Smith & Nephew?

1

When was bone cement approved by the FDA?

1

A method to get polyethylene to wear/ oxidize less, therefore increasing its longevity is called .

1

If a surgeon wanted to preserve the Pcl or even the acl what approach would you call this?

1

You can keep all ligaments in a Uni (partial) knee replacement.

1

If the surgeon wanted to keep a viable PCL intact and wants femoral roll back which tibial implant design would he or she use.

1

The first implant design for knees was a hinge joint in 1890

1

What factor greatly advanced surgery?

1

Which implant design is most commonly used for revision knee surgery?

1

Which implant component is seen?

1

is the term for bone loss. Seen in polyethylene wear and the debris react with the bone.

1

When you have an infected knee after a TKA you use antibiotics to clear the infection and then the patient can have a revision.

1

When a surgeon in cutting the femur, he or she must not " " the femur. This means cutting the cortical bone which could lead to a rupture.

1

In TKA surgery the femur gets cut multiple times before implant placement. What is the first cut made?

1

What axis are you taking into account with the distal femur cut?

1

IM approach stands for intramedullary. The approach can be seen when drilling the femur & when inserting a rod into the femur.

1

What does the Doctor use to size the femoral implant?

1

When cutting the femur which is the most important?

1

How many femoral cuts are needed if using a PS insert?

1

The tibia sizing guide is what approach?

1

The tibia sizing guide cannot adjust for varus or valgus

1

What can be used to save time, perfect a patients implant design and get better cuts ?

1

If a knee is presented with minimal wear and a surgeon wanted to keep all ligaments, what could he or she preform?

1

Which side of the knee is the most compromised out of all needed TKAs.

1

Which x-ray view is shown?

1

What view and which knee is shown?

1

This radiograph is showing the view.
