You're Pathological
The motion limited by Patella Baja Syndrome
What is knee extension?
The structure in the knee with the greatest capacity to heal on its own
What is the MCL?
Lachman and Anterior drawer test apply anterior force to test for this
What is ACL tear/laxity?
This causes the knee to buckle in loading phase
What is knee extensor (quadriceps) weakness?
The portion of the menisci which are avascular
What is the inner 1/3?
The three members of the Unhappy Triad
What is ACL, MCL and medial meniscus?
Occurs in max extension to "lock" the knee
What is screw home mechanism?
The force applied to the tibia in order to increase knee extension
What is anterior glide?
Will cause lateral thrust gait
What is genu varum?
Bone or tissue transferred from one point to another of the same person's body
What is autograft?
Special tests used for patellar fracture
What is none, X ray only?
The 5 nerves of the lower extremity
What is sciatic, obturator, femoral, tibial, and fibular (peroneal) nerves?
Force(s) that cause ACL tear
What is valgus at the knee, internal rotation of the femur and external rotation of the tibia?
The most likely compensation in terminal stance s/p TKA
What is early heel rise due to lack of knee extension?
This functions to increase quadricep strength by 25%
What is the patella?
The "U" in UKA
What is unicompartmental?
4 functions of the menisci
What is stabilize knee, increase joint congruency, lubricate joint, absorb shock/distribute weight?
The PCL limits this
What is posterior translation of the tibia on the femur?
Causes knee collapse in terminal stance
What is gastroc/soleus weakness?
When a graft is most vulnerable
What is 6-8 weeks post-op?
The purpose of a High Tibial Osteotomy
What is to change alignment of the joint, to shift the weight-bearing surfaces toward areas that are less damaged, to buy time before a TKA is needed?
The muscle which unlocks the screw-home mechanism
What is popliteus?
Osteokinematics of the knee into a mini squat
What is "As the femur moves posteriorly, the femoral condyles glide anteriorly"?
Compensation for weak quads in loading phase
What is forward lean/lurch to lock knee?
The knee in pronation
What is flexion, valgus, and internal rotation?
