Q: The Bounce Home Test evaluates problems with full knee [...].
A: extension
Q: What test is being described? The patient is supine and the physician grasps the heel. The knee is flexed completely. Then, the knee is allowed to drop into extension.
[...]
A: Bounce Home Test
Q: What indicates a positive Bounce Home Test?
[...]
A: Incomplete extension
Comment: This is usually due to meniscal tears or joint effusions.
Comment 3: Normally, the knee should "bounce home" into full extension to a sharp end-point, without restriction.
Topic: Knee
Bone Wizardry Lock: If the knee cannot fully extend passively, something is blocking it. Meniscal tears and joint effusions are the two common culprits.

Q: The Apley's Compression and Distraction Tests evaluate the [...] and [...] structures of the knee.
A: meniscus; ligamentous
Q: What test is being described? The patient lies prone and the knee is flexed to 90°. Compression is performed with the physician pressing straight down on the heel, and internally and externally rotating the tibia. Then the physician pulls upwards on the foot, and internally and externally rotates the tibia.
[...]
A: Apley's Compression and Distraction Tests
Q: Pain elicited during the Apley's Compression test indicates a [...].
A: meniscal tear
Q: Pain elicited during Apley's Distraction Test indicates a [...] injury.
A: ligamentous
Comment 4: Usually the medial and/or lateral collateral ligaments.
Topic: Knee
Bone Wizardry Lock: Compression loads the meniscus; distraction pulls on the collaterals. Same rotation setup, different structure blamed depending on which phase hurts.

Q: The Lachman's Test assesses the stability of the [...].
A: ACL
Q: Which test is more accurate, the Anterior Drawer Test or Lachman's Test?
[...]
A: Lachman's
Q: What test is being described? The patient lies supine. The physician grasps the proximal tibia with one hand and the distal femur with the other hand. The knee is flexed to about 30°. The tibia is then pulled forward by the grasping hands.
[...]
A: Lachman's Test
Q: What indicates a positive Lachman's Test?
[...]
A: Excessive forward motion of the tibia
Topic: Knee
Bone Wizardry Lock: Lachman is performed at 30 degrees; the Anterior Drawer is at 90. The difference in knee position is why Lachman is more accurate.

Q: [...] is the high-yield ACL test using anterior tibial translation at about 20 to 30 degrees of knee flexion.
A: Lachman
Topic: Knee
Bone Wizardry Lock: Anterior tibial pull means ACL. Posterior tibial push means PCL.

Q: [...] screens meniscal injury by combining knee flexion/extension with tibial rotation and joint-line stress.
A: McMurray
Topic: Knee
Bone Wizardry Lock: Twist-plus-joint-line symptoms should make meniscus rise on the list.

Q: Valgus stress tests the [...]; varus stress tests the [...].
A: MCL; LCL
Topic: Knee
Bone Wizardry Lock: Collateral ligament questions are side-opening questions.
