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