ACL role/function - ANSWER Stabalize knee extension
PCL role/function - ANSWER RESTRICT Posterior Translation of tibia on
femur during knee flexion.
RESTRICT knee hyper flexion
MCL role/function - ANSWER RESTRICT Valgus
LCL role/function - ANSWER RESTRICT Varus
ACL moi? - ANSWER Non-contact, COMBINED movements = foot planted +
knee hyperextension, Genu Valgus + Tibial Rotation (plant and pivot), BLOW
to Lateral side of knee, "Unhappy Triad"
"Unhappy Triad"? - ANSWER HIGH VALGUS tears ACL, MCL, and
MEDIAL MENISCUS
PCL moi? - ANSWER Rare alone, happens when other injured tissue is
contacted. CONTACT: fall and land on tibial tuberosity WHILE knee FLEXED
"Dashboard Injury"? - ANSWER In automobile: Head on collision where tibia
HITS dashboard
MCL moi? - ANSWER Non-Contact = foot PLANTED while PIVOTING in
opposite direction.
, Contact = blow to lateral side of knee, HIGH VALGUS force
LCL moi? - ANSWER Non-Contact = foot PLANTED while PIVOTING in
opposite direction.
Contact = blow to lateral side of knee, HIGH VALGUS force
Orthopedic Tests for Ruptured ACL? - ANSWER Anterior Drawer Test
Pivot Shift
Lachman's
ACI surgery - ANSWER Autologous Chondrocyte Implantation, aka,
Chondrocyte Transplantation
Indication for ACI surgery? - ANSWER YOUNGER Patients with single,
larger full-thickness chondral and osteocondral DEFECT of FEMORAL
CONDYLE or PATELLA.
Procedure for ACI surgery? - ANSWER Cartilage HARVESTED
Arthroscopically, chondrocytes EXTRACTED from articular cartilage and
CULTURED for weeks, IMPLANTATION via ARHTROTOMY (open
procedure)
Patient Position Post Op ACI surgery? - ANSWER Important to position to
allow GRAVITY to EVENLY DISTRIBUTE chondrocytes along base of
defect. Example: Patellar Surface repair = patient in prone
Duration of implant maturation for ACI surgery? - ANSWER 6 to 9 months
Microfracture Surgery - ANSWER Indicated for small defects such as medial or
lateral femoral condyle or patella. Arthroscopic procedure.
Purpose of Microfracture Surgery? - ANSWER STIMULATE bone marrow
repair for ingrowth of cartilage repair tissue
PCL role/function - ANSWER RESTRICT Posterior Translation of tibia on
