Knee fun fact BINGO - Call List

(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

1. With slack ligaments, we have ~40˚ of rotation at 90˚ of knee flexion
2. Compressive forces behind the patella increase by a factor of 0.5x body weight, 3.3x with stairs, & 7.6x with squats
3. The articular cavity does not include the cruciate ligaments as the capsule folds around the intercondylar area
4. The patella, a sesamoid bone, slides against smooth space between condyles & provides an increased moment arm for the quads during knee extension
5. In addition to quads & hamstrings, other knee muscles include sartorius, popliteus, gastrocs, and plantaris
6. Menisci (shallow bowls of fibrocartilage) deepens tibial plateau with medial larger & oval shaped, while lateral smaller & rounder
7. The MCL resists valgus force while the LCL resists varus force
8. Wedge-shaped menisci provide increased surface area and stability for the knee joint
9. More flexion leads to more patella compression where the cartilage is the thickest
10. Quads are multipennate design, better for power, with the patella increasing peak torque @ ~60˚flexion
11. Medial femoral condyle is more curved & medial tibial condyle is more concave front to back
12. Average Q-angle is ~15˚; beyond 20˚ is knock-kneed or genu valgus whereas less than 10˚is bow-legged or genu varum
13. The knee is actually a double hinge with different shapes of fused lateral and medial condyles; this allows some rotation
14. The patella encounters the condyles at 15-20˚ of flexion
15. Medial femoral condyle twists inward toward lateral condyle in sagittal plane; both wider most distally
16. In weight bearing (WB), femur rotates on tibia whereas in non-WB (NWB) tibia rotates on femur
17. A shorter patellar tendon = baja while a longer one = alta
18. Menisci are thinnest @ middle of joint and widest at outermost part
19. Intercondylar eminence separates medial & lateral tibial plateau; gives rise to ACL & PCLs
20. Hamstrings are mostly strap/fusiform design, better for ROM & creates most force eccentrically (esp near end ROM)
21. The knee’s synovial membrane is the most extensive in the body with lots of bursae due to overlapping strap-like muscles
22. Knee rotation due to joint structure (vs. muscle function) aka screw home mechanism for stability in extension
23. The ACL resists anterior tibial glide while the PCL resists posterior tibial glide
24. All knee ligaments are tightest in extension
