The medical terminology for the "knee joint"

Tibiofemoral 

200

The largest sesamoid bone in the body

patella

300

This bony landmark was formed by the pull of the patellar tendon

Tibial Tuberosity

400

This non-weight bearing bone is included in the knee because this structure attaches to it. (2 answers)

Fibula , LCL

500

The meniscus sit on top of this bony structure

Tibial plateaus

Pathologies

100

This injury occurs most commonly after a direct blow to the lateral aspect of the knee

MCL Sprain

200

This injury is one of the least common injuries to the knee and result from a direct blow to the medial knee

LCL Tear

300

A patellar subluxation can be aided back into its correct position by performing this motion

Knee Extension

400

This injury demonstrates poor healing on its own due to lack of blood supply

Meniscus Tear

500

This injury is traumatic and results in tearing of multiple or all ligaments in the knee, commonly seen in Football

Knee Dislocation

Special Tests

100

These special tests can be performed by placing the same stress to the ligament as the MOI. One hand stabilizes at the lower leg while the other hand places force to the knee

Varus & Valgus

200

This test is performed by applying compression to the menisci to elicit pain followed by distracting the knee joint to alleviate pain

Apley's Compression and Distraction

300

This special test is considered the Gold Standard for diagnosing ACL tears

Lachmens

400

This special test can be performed prone or supine.

Anterior Drawer or Lachmens

500

This test is performed solely by the patient and does not require the clinician to palpate or stabilize

Thessaly

Ligaments

100

This ligament protects against valgus force

Medial Collateral Ligament MCL

200

This ligament protects against varus force

Lateral Collateral Ligament

300

This ligaments is commonly torn in conjunction with the meniscus because of its attachment

MCL, Medial Meniscus

400

The ligaments keep the patella in the correct anatomical position

Patellofemoral ligaments

500

These ligaments can be found inside the knee and protect against translation of the tibia

Cruciate Ligaments (ACL, PCL)

Muscles

100

When this muscle group contracts they act on the knee to perform extension

Quadriceps

200

When this muscle group contracts they act on the knee to perform flexion

Hamstrings

300

This muscle is very important because it aids in stabilizing the knee during motion

Vastus Medialis Oblique

400

This muscle originates from the calcaneus and crosses over the back of the knee to insert on the Femur

Gastrocnemius

500

This small muscle is important because it locks and unlocks the knee to allow for stable movement

Popliteus
