Knee Jt
Flashcards do conjunto (16)
- 1Lat side: Biceps femoris tendon Ant: Quadriceps tendon (encloses patella) Med: Sartorius, gracilis, semitendinous, semimembraneousRelations of the knee jt
- 2What are the 3 separate articulations of the knee jt? What doesn't articulate at the knee jt?- femoropatellar
- femorotibial (x2)
The FIBULA - 3—Articular surfaces of the knee
- 4Ant: - fuses w quadriceps tendon, patella and lufamentum patellae Post: - Encloses intercondylar fossa of femur, open posterior to lateral condyle of tibia for popliteus muscleCapsule Attachments
- 5—
- 6—
- 7(Red) Expansion of semimebranosus tendon Reinforces posterior capsule (Blue) - Thickening of capsule over popliteus Strengthens posterolateral jt capsuleRed = Oblique Popliteal lig
Blue = Arcuate lig
- 8Strong, flat, thickening of capsule - Med epicondyle and superior medial surface of tibia - Deep fibres attach to medial meniscusMedial (tibial) collateral lig
- 9Strong and cord-like - lateral epicondyle of femur-> lateral head of fibulaLateral (fibular) Collateral lig
- 10Taut in every jt position Maintains contact between femoral and tibial articular surfaces when knee is flexed Winds around each other during medial rotation of the tibia -> limited to 10oCruciate ligs
- 11Anterior intercondylar area of tibia -> medial side of lateral condyle of femur Spirals through 110o between tibia and femur Anteromedial band -> limits flexion Posterolateral band -> limits extensionAnt Cruciate lig
- 12Posterior intercondylar area of tibia -> lateral side of medial condyle of femur Closely aligned to centre of rotation of knee Anterolateral band -> limits flexion Posteromedial band -> limits extensionPosterior Cruciate lig
- 131) limits posterior displacement of the tibia 2) limits anterior displacement of the tibiaCruciate ligs
1) PCL (post cruciate lig)
2) ACL (ant cruciate lig)
- 14Wedges of fibrocartilage, deepen articular surface, shock absorption Medial: C-shaped, broad post, firmly attached to TCL Lateral: circular, freely moveable, attachment for popliteusMenisci
- 15Meniscal Attachments
- 16—B supply to knee:
4 Genicular branches from popliteal A
Descending genicular A from Femoral A
Decsending branch from lat circumflex femoral A
Recurrant branches from anterior and posterior tibial As
