Final Flashcards
What type of joint is the stifle?
Complex condylar synovial joint
Name the three joints in the stifle.
- Femorotibial
- Femoropatellar
- Proximal tibiofibular
Name the three synovial joint capsules in the stifle. Which is the largest?
- Lateral Femorotibial
- Medial femorotibial
- Femoropatellar (LARGEST)
What are the menisci made of and which one is thicker?
Fibrocartilage
Lateral menisci
Name the three meniscal ligaments of the stifle.
- Meniscotibial ligaments (cranial and caudal)
- Transverse (intermeniscal) ligament
- Meniscofemoral ligament
Where is the meniscofemoral ligament?
Courses between the caudal part of the lateral meniscus and the medial femoral condyle near the intercondylar fossa.
What fibrocartilages prevent luxation of the patella?
Medial and lateral parapatellar ligaments
Name all the femorotibial ligaments.
- Cranial cruciate ligament
- Caudal cruciate ligament
- Medial collateral ligament
- Lateral collateral ligament
Which femorotibial ligaments are considers intra-articular and extra-articular?
Intra-articular: Medial/Lateral collateral ligaments
Extra-articular: Cranial/caudal cruciate ligaments
How would you test the collateral ligaments of the stifle?
Lateral: Varus stress test
Medial: Valgus stress test
How are the cruciate femorotibial ligaments named?
For their attachment to the tibia.
What are the functions of the cranial cruciate ligament?
- Prevent tibia from sliding cranially
- Prevent hyperextension
- Limit internal rotation of tibia mainly during flexion
- Prevent excessive varus and valgus movement of tibia during flexion
What are the functions of the caudal cruciate ligament?
- Prevents tibia from moving caudally during weight bearing
- Limit internal rotation of tibia mainly during flexion
- Secondary help for preventing excessive varus and valgus movement of tibia during flexion
What are the function of the collateral ligaments of the stifle?
- Prevent internal rotation of tibia mainly during extension
- Prevent external rotation of tibia in flexion and extension
How could you test a ruptured cranial cruciate ligament?
Cranial drawer test Tibial compression test Radiographs Synovial fluid analysis MRI Arthroscopy
What are the three most common treatments used for a ruptured cranial cruciate ligament?
- TPLO (Tibial plateau leveling osteotomy)
- Extracapsular reconstruction with a lateral suture or TIGHTROPE
- Tibial tuberosity advancement
