Limited Knee flexion

Question 1

Limited knee flexion Tasks

Answer 1

WA & SLA

Question 2

Limited Knee flexion Phase

Answer 2

LR, PSw –> ISw

Question 3

Limited Knee flexion Primary cause WA

Answer 3

Weak quads, IMC (Quad activity), Impaired proprioception, tibiofemoral/patellofemoral pain, Knee EXT contracture (WA)

Question 4

Limited Knee Flexion Secondary cause WA

Answer 4

To a plantar flexion posture, to abnormal plantar flexor activity, to forefoot/flatfoot contact (WA)

Question 5

Limited knee flexion compensatory (WA)

Answer 5

for an ACL deficiency (WA)

Question 6

Limited knee flexion Functional significance

Answer 6

Decreased shock absorption, decreased fwd momentum of tibia, potential injury to posterior knee capsule

Question 7

Limited Knee flexion Primary cause (SLA)

Answer 7

IMC (abnormal RF/ Knee extension activity), tibiofemoral/patellofemoral pain, knee extension contracture (SLA)

Question 8

Limited knee flexion secondary cause (SLA)

Answer 8

to inadequate hip flexors (weakness), to inadequate hip extension in TSt (flexion contracture), to inadequate hamstrings activity in PSw, no heel off in TSt [excess doors flexion] (SLA)

Question 9

Limited knee flexion compensatory

Answer 9

None

Question 10

Limited knee flexion functional significance

Answer 10

Interferes with foot clearance,

↓ in flexion during PSw & therefore Isw,

Increase Energy Cost (SLA)
