- 1How many degrees of freedom does the iliofemoral joint have ?3
- 2What are the osteokinematic motion of the iliofemoral joint?Flexion
Extension
ABD
ADD
Lateral rotation
Medial rotation - 3What is the loose pack position for the iliofemoral joint?30 degrees of flexion
30 degrees of ABD
Slight lateral rotation - 4WHat is the close pack position for the iliofemoral joint?Full extension
Medial rotation - 5What is the capsular pattern for the iliofemoral?Flexion
ABD
Medial rotation (can be most limited) - 6Where is the iliofemoral ligament and it's function?From anterior inferior iliac to intertrochanteric line of femur.
Strongest ligament in the body.
It prevent excessive hip extension and assist with posture. - 7Where is the pubofemoral ligament and it's function?From the pubis to the neck of the femur.
It prevents excessive ABD of the femur. - 8Where is the ischiofemoral ligament and it's function?From the ishical wall to the neck of the femur.
Weakest of the three iliofemoral joint ligaments.
Reinforces the capsule. - 9How many degrees of freedom does the tibiofemoral have?2
- 10What are the osteokinematic motion of the tibiofemoral joint?Flexion
Extension
Medial/lateral rotation (slightly during testing motions) - 11What is the loose pack position for the tibiofemoral joint?25 degrees of flexion
- 12What is the close pack positoon of the tibiofemoral joint?Full extension
lateral rotation of the tibia - 13What is the capsular pattern for the tibiofemoral joint?flexion
extension - 14Where is the ACL and it's function?Anterior cruciate ligament
Anterior intercondyle lining of tibia to posterior medial aspect of femur.
Prevents anterior displacement of tibia on femur. - 15What is the mechanism of injury for an ACL tearNoncontact twisting motion of tibia on femur.
Associated with hyperextension and valgus/varus stress to the knee.
Tibia is forced severely anteriorly from femur. - 16Where is the PCL and it's function?Posterior cruciate ligament
Posterior intercondyle lining of the tibia to medial/anterior/lateral aspect of the femur.
Prevents posterior displacement of the tibia on the femur. - 17What is the mechanism of injury for the PCL?When the tibia and femur are in contact during knee flexion.
Tibia is forced posteriorly on the femur or the femur is forced anteriorly on the tibia.
Common in car accidents when leg is struck on gas paddle. - 18Where is the MCL and it's purpose?Medial collateral ligament
Medial femoral epicondyle to the shaft of the tibia.
Prevents valgus displacement of the tibia on the femur. - 19What is the mechanism of injury for the MCL?Valgus stress load on the knee without rotation.
Common to also tear the ACL and medial meniscus as well. - 20Where is the LCL and it's purpose?Lateral collateral ligament
Lateral femoral epicondyle to the head of the fibula.
Prevents varus displacement of the tibia on the femur. - 21What is the mechanism of injury for the LCL?Varus stress on the knee with out rotation.
Common to tear ACL or PCL as well. - 22How many degrees of freedom does the talocrural joint have?1
- 23What are the osteokinematic motion of the talocrural joint?Dorsifelxion
Plantar flexion - 24What is the loose pack position of the talocrural joint?10 degrees of plantar flexion
Midway between inversion/eversion - 25What is the close pack position of the talocrural joint?Max dorsiflexion
- 26What is the capsular pattern for the talocrural joint?Plantar flexion
Dorsiflexion - 27What makes up the subtalar joint?The talus and calcaneus
- 28How many degrees of freedom does the subtalar joint have?1
- 29What are the osteokinematic motion of the subtalar joint?Inversion
Eversion - 30What is the loose pack position of the subtalar?Midway between extremes of ROM
- 31What is the close pack position of the subtalar joint?Supination
- 32What is the capsular pattern for the subtalar joint?Limited varus ROM
- 33What makes up the midtarsal joint?Talus
Calcaneuos
Navicular
Cuboid - 34What are the osteokinematic motion of the midtarsal joint?Inversion
Eversion - 35What is the loose pack position of the midtarsal joint?Midway between extremes of ROM
- 36What is the close pack position of the midtarsal?Supination
- 37What is the capsular pattern of the midtarsal joint?Dorsiflexion
Plantar flexion
Inversion
Medial rotation
