Exam 1 - Packets Flashcards
Tibiofemoral Joint is what kind of joint
Modified hinge joint
Resting position of tibiofemoral
25 degrees of flexion
Closed pack position of tibiofemoral
full extension, ER of tibia
Capsular pattern of tibiofemoral join
flexion, extension
Patellofemoral joint is what kind of joint

What kind of joint is the superior talofibular joint
plane synovial joint
Terrible triad
MCL, medial meniscus, and ACL (injured in valgus force)
What is injured during hyperextension of knee
ACL
What is injured during knee flexion with posterior translation
PCL
What is injured from varus force to kne
LCL, posterolateral capsule, PCL
Osgood Schlatter disease
Injury to tibial tubercle apophysis
Injury to knee occurring after acceleration and twisting
Medial meniscus
Injury to knee that can occur after deceleration
Cruciates
Injury to knee after constant speed with cutting
ACL
Pathology when knees touch and ankles do not
Genu valgum
Pathology when 2 or more fingers fit between knees with ankles together
Genu varum
Medial tibial torsion is associated with
Genu varum
Lateral tibial torsion is associated with
Genu valgum
Angle where you need most knee extensor muscle force
60 degrees flexion
Angle where you need most knee flexor muscle force
45-10 degrees flexion
Degree of knee flexion required for:
Activities
Sitting in a chair
Going up steps
117, 90, 80
Primary rotary stabilizers of the knee
Cruciates
Resting position of hip joint
30 degrees flexion and abduction, lateral rotation
Closed pack position of hip joint
extension, medial rotation, and abduction
Capsular pattern of hip joint
Flexion, abduction, medial rotation
Forces acting at hip in standing
.3x BW
Forces acting at hip one leg stand
2.4 to 2.6 x BW
Forces acting at hip walking
1.3 to 5.8 x BW
Forces acting at hip on stairs
3x BW
Forces acting on hip running
4.5+ x BW
Limb position in posterior hip dislocation
Shortened, adducted, and medially rotated
Greater trochanter is prominent
Limb position in anterior hip dislocation
Limb is abducted and laterally rotated.
May appear cyanotic or swollen
Limb position in intertrochanteric fracture
Limb is shortened and laterally rotated
Internal snapping in hip
Iliopsoas or iliofemoral ligament slipping over lesser trochanter
Noted at 45 degrees flexion and felt anteriorly with hip moving from flexion to extension
External snapping in hip
IT band/gluteus maximum tendon riding over greater tuberosity of the femur
Intra-articular snapping of hip
due to labral tears or loose bodies
Sharp pain in groing/anterior thigh area
Sports hernia
Deficient inginual canal posterior wall, nerve entrapment, or adductor tendonopathies
Lateral hip pain
trochanteric buritis or tear of gluteus medius
May also stimulate L4 nerve root pain so assessment of back should be considered
Squinting patellae
Patella face in, toe in posture, likely excessive pronation, possible IR of femur on tibia
Grasshopper or Frog eye patellae
patella face out, toe out posture, supinated, possible ER of femur/tibia
Signs of cam/pincer impingement
Sharp anterior groin pain with full flexion, adduction, and medial rotation
Clinical prediction rules of OA
- Limited active hip flexion with lateral hip pain
- Active hip extension causes pain
- Limited passive medial rotation (25 or less)
- Squatting limited and painful
- Scour test with adduction causes lateral hip or groin pain
Harris Hip scale
Used for rating hips pre and post sx
Emphasizes pain and function
HOOS scale
assessing patients with OA undergoing conservative treatment or total hip replacement
