Question 1

Outcome = ?

Answer 1

• The more posterior the joint is to the TKA line the more knee extension is promoted. Thus more stability but harder to initiate knee flexion in swing.
• The more anterior the joint is to the TKA line the more flexion is promoted, thus more unstable but easier to move.

Question 2

Outcome = ?

Answer 2

Too much internal rotation = Lateral knee whips

Question 3

Outcome = ?

Answer 3

Too much external rotation = Medial knee whips

Question 4

Outcome = ?

Answer 4

Forces knee into extension at heel strike

Question 5

Outcome = ?

Answer 5

Forces knee into flexion at heel strike

Question 6

Outcome = ?

Answer 6

Creates early knee flexion in mid-stance

Question 7

Outcome = ?

Answer 7

Creates delayed knee flexion in mid-stance

Question 8

Outcome = ?

Answer 8

Encourages excessive knee flexion in early stance which can be dangerous for low level or beginner amputee but can help advanced BK’s to have easier roll over.

Question 9

Outcome = ?

Answer 9

Excourages excessive knee extension throughout stance which is safe, but can produce a hill climbing sensation of premature heel rise at the end of stance.

Question 10

Outcome = ?

Answer 10

• Does not affect knee.
• Prosthetic foot needs to match the uninvolved.

Question 11

Outcome = ?

Answer 11

Creates a moment that increases knee flexion

Question 12

Outcome = ?

Answer 12

Creates a valgus moment at the knee.

Question 13

Outcome = ?

Answer 13

Creates a varus moment at the knee.

Question 14

• Outcome = ?

Answer 14

Creates a moment that increases knee extension.
