KIN 2236 Final Exam newest 2025 with 250 accurate and
verified questions covering biomechanics, functional
anatomy, musculoskeletal movement, and applied
kinesiology principles.
What should you check when there is significant MCL injury? -
ANSWER-ALWAYS CHECK THE PCL AND ACL because
they are the 2nd line of support against that mechanism
Anatomy of the ACL - ANSWER-- Runs from the ant. aspect of
tibial plateau to post. medial aspect of lateral femoral condyle
- primary restrain to ant. tibial ext.
- greatest translation occurs at 20-30 degrees
What are the 2 major bundles that are named for their
attachment on the tibia (ACL)? - ANSWER-- Anteromedial --
tighter in flexion
- Posterolateral -- tighter in extension
What is the stabilizing role of the ACL? - ANSWER-- weaker of
the two cruciate ligaments
,2|Page
-- functions to restrict posterior translation of the femur relative
to the tibia during weight bearing
-- restricts anterior translation of the tibia during non weight-
bearing
--- stops tibia from sliding forward
- but if its fixed, stops femur from sliding backwards
-- also limits excessive rotation of the tibia
--- bad collateral (LCL/MCL) issue, check ACL/PCL bc they are
the secondary restraints
-- secondary support for valgus and varus with collateral
ligament damage
- running from front to back
Anatomy of the PCL - ANSWER-- The PCL originates on the
lateral aspect of the medial femoral condyle and inserts
posteriorly to intercondylar area of tibia
- passes medially to the ACL
- Larger and stronger than the ACL
- primary restraint to posterior tibial translation
- Greatest translation occurs at 20-30 degrees

What are the 2 major bundles that are named for their
attachment on the tibia (PCL)? - ANSWER-- Anterolateral --
Tight in Flexion
- Posteromedial -- Tight in Extension
Stabilizing Role of the PCL - ANSWER-- Stronger of the two
cruciate ligaments
- Functions to restrict anterior translation of the femur relative to
the tibia during weight bearing
- restricts posterior translation of the tibia during non-weight
bearing
- Also limits hyper-internal rotation
- Secondary support for valgus and varus with collateral
ligament damage
- running from top-down (anterior translation)
-- fixed on ground vs fixed femur
Screw Home Mechanism and the PCL - ANSWER-- when it
goes into extension (passive, balls slide into the cavities
-- bends around posteromedial bundle (can be shared w/ the
wrong type of movement)
, 4|Page
The Meniscus - ANSWER-- One believed to be a useless
remnant of intra-articular attachments
- Serve essential roles in maintaining knees function
-- stabilize knee by increasing concavity of tibia (better bony fit,
stability) which gives the femoral condyles something to sit in
-- shock absorption
--- full extension = 45-50% of load
--- 90 degree flexion = 85% load
--- compression facilitates distribution of nutrients
The Medial Meniscus - ANSWER-- C-shaped
- Larger radius of curvature
- Tight connection with capsule and MCL
- Poor mobility increases tear on medial side
The Lateral Meniscus - ANSWER-- O-shaped
- Smaller (tighter) radius of curvature
-- more mobile and torn (bad news, torn and loose)
- Attached loosely to capsule and popliteal tendon
- Increased mobility
