Ligaments Flashcards
0
Q
TCL (MCL)
A
- from medial epicondyle of femur to medial condyle and superior part of tibia
- deep fibers attach to medial meniscus
1
Q
Patellar ligament
A
- continuous with quadriceps tendon
- connects apex of patella to tibial tuberosity
2
Q
Oblique popliteal ligament
A
Reflected expansion of semimembranosus tendon that strengthens joint capsule posteriorly
3
Q
Cruciate ligaments
A
- medial rotation - limited, 10 degrees
- lateral rotation - unwind, 60 degrees
- crossing over point - pivot for rotary movements at knee
4
Q
Medial meniscus
A
- C-shaped
- broader posteriorly
- adheres to TCL (MCL)
7
Q
ACL limits…
A
- hyperextension
- posterior rolling of femoral condyles on tibia during flexion - spin
- anterior glide of tibia on femur
8
Q
PCL
A
- stronger
- “pain” – runs anteriorly and inferiorly to medial femoral condyle
- in weight-bearing of flexed knee, PCL is main stabilizing factor for femur
9
Q
Menisci
A
- Fibrocartilage plates
- shock absorber, smooth articular surface, and deepens surface
- thicker at external margins - attach to fibrous layer of joint capsule
- transverse ligament of knee - joins anterior edges of meniscus
12
Q
Lateral meniscus
A
- circular
- smaller
- more freely moveable
- separated from FCL by popliteus
13
Q
FCL (LCL)
A
- from lateral epicondyle of femur to lateral surface of head of fibula
- popliteus passes deep to LCL
14
Q
PCL limits…
A
- hyperflexion
- anterior rolling of femur on tibia during extension – spin
- posterior glide of tibia on femur
15
Q
ACL
A
- weaker
- “apex” - runs posteriorly and externally to lateral femoral condyle
18
Q
Intra-articular structures
A
- cruciate ligaments
- meniscus
- popliteus
