- Knee joint AK
- TKA line position
- Outcome = ?
a) 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.
b) The more anterior the joint is to the TKA line the more flexion is promoted, thus more unstable but easier to move.
- Knee,
- Excessive IR,
- Outcome = ?
Too much internal rotation = Lateral heel whips
- Knee,
- Excessive ER,
- Outcome = ?
Too much external rotation = Medial knee whips
- Heel,
- Too Hard,
- Outcome = ?
Forces knee into flexion at heel strike
- Toe Break/Foot
- Too Posterior
- Outcome = ?
Creates early knee flexion in mid-stance
- Toe Break/Foot
- Too Anterior
- Outcome = ?
Creates delayed knee flexion in mid-stance
- Ankle Moment
- Dorsiflexion
- Outcome = ?
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.
- Ankle Moment
- Plantarflexion
- Outcome = ?
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.

- Foot Placement (Side Foot)
- Posterior
- Outcome = ?
Creates a moment that increases knee flexion
- Foot Placement (Side Foot)
- Lateral
- Outcome = ?
Creates a valgus moment at the knee.
- Foot Placement (Side Foot)
- Medial
- Outcome = ?
Creates a varus moment at the knee.
- Foot Placement (Side Foot)
- Anterior
- Outcome = ?
Creates a moment that increases knee extension.
- Lateral Bending can be caused by…
- Prosthesis is too short, ot high medial wall
- which will lead to = ?
- poor balance
- abduction contracture
- short residual limb
