PTAP 1320 - TEST # 2 - QUESTIONS WITH COMPLETE SOLUTIONS, GRADED A+.
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 force can tear the ACL, MCL, and MEDIAL MENISCUS
PCL moi? - (answer)Rare on its own, happens when other tissue damaged. CONTACT: falling and landing
on tibial tuberosity WHILE knee FLEXED
"Dashboard Injury"? - (answer)In car: Head on collision where tibia STRIKES 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

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)Critical to position for 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
Osteotomy - (answer)Surgical CUTTING and REALIGNING/REPLACING of bone. Extra-Articular. Done for
Management of impairments.
KNEE Osteotomy - (answer)Surgery on DISTAL femur or PROXIMAL tibia to REDISTRIBUTE Weight
Bearing forces between tibia and femur to REDUCE JOINT PAIN and DELAY arthroplasty.
Why is a knee osteotomy less common now? - (answer)Advancement in Joint Replacement procedures.
