what hip ligament resists flexion and external rotation

ligamentum teres
what structure lines the articular capsule
- synovial membrane
- communicating bursa present bc weakness of capsule
what hip ligaments prevent dislocation
- pubofemoral
- transverse acetabular ligament (inferior)
differences between shoulder and hip
- bony congruency- hip better, deep socket
- labrum- helps deepen socket but more important in shoulder
- muscle support- shoulder less to allow for more ROM
knee joint articulations
- patella femoral
- medial knee
- lateral knee
patellofemoral joint
- plane joint (partial arthroidal)
- btwn patella and patellar surface of femur
medial knee joint
- condyloid joint
- btwn medial femoral condyle and medial tibial condyle
lateral knee joint
- condyloid joint
- btwn lateral femoral condyle and lateral tibial condyle
what motion do the knee condyloid joints allow for
- flexion
- extension
- some internal/ external or medial/lateral rotation of femur on fixed tibia or vise versa
what tibial plateau smaller
- lateral
- --more susceptible to instability bc flatter
does femur sit more medial or lateral?

Medial
Terminal extension (screw home mechanism)
- Anterior roll, posterior slide, internal rotation of femur on fixed tibia
- Locks in due to intracondylar eminence in intercondylar fossa and ligamentous structures
The anterior posterior distance of what plateau is longer?

Medial
Tibial plateau articular surface

Hyaline cartilage and menisci
