ART. GENUS

Question 1

ART GENUS =

Answer 1

Articulatio genus
• Articulatio femoropatellaris
type: 
- diarthrosis, 
- articulatio simplex, 
- articulatio delabens, 
- uniaxial
• Articulatio femorotibialis
type: 
- diarthrosis, 
- articulatio duplex, 
- articulatio condylaris, 
- biaxial

Question 2

EXTRACAPSULAR ligaments (Ligg. extracapsularia) of stifle joint:

Answer 2

Retinaculum patellae (1):

• from fascia lata and aponeurosis of muscles,
• covers stifle

Lig. patellae (2):
- Continuation of M.QUADRICEPS FEMORI’s tendon,
- the PATELLA is a sessamoid bone in the tendon before patellar ligament INSERTS on TIBIAL TUBEROSITY
Ca: *1
Eq: *3

Lig. collaterale laterale (3):
from lateral EPICONDYLE of femur to HEAD of fibula, a lesser part to lateral condyle of tibia;
Underneath there is the TENDON of M.POPTLITEUS

Lig. collaterale mediale (4):
from medial EPICONDYLE of femur to DISTAL part of tibia’s medial condyle;
it also attaches strongly to MEDIAL MENISCUS

Question 3

Capsular ligaments (Ligg. capsularia) of stifle joint:

Answer 3

Lig. femoropatellare laterale (5):
from lateral VERSALIUS (sesamoid) bone to PATELLA, also attaches to lateral femoral EPICONDYLE; Reinforcement of joint’s capsule

Lig. femoropatellare mediale (6):
from medial VERSALIUS (sesamoid) bone to PATELLA, also attaches to medial femoral EPICONDYLE; Reinforcement of joint’s capsule

Lig. popliteum obliquum (23):
fibrous reinforcement in caudal wall of joint capsule

Question 4

Intracapsular ligaments (Ligg. intracapsularia) of stifle joint

Answer 4

Lig. transversum genus (15):
connects CRANIAL ANGLES of the two MENISCUS
In EQ: Ø

Lig. meniscotibiales:
from cranial and caudal ends of
BOTH MENISCUS–> TIBIA

▪ Lig. craniale menisci laterale (16):
area intercondylaris cranialis lateralis

▪ lig. craniale menisci mediale (17):
area intercondylaris cranialis medialis

▪ lig. caudale menisci laterale (18):
incisura poplitea

▪ lig. caudale menisci mediale (19):
area intercondylaris caudalis

Lig. cruciatum craniale (20):
from lateral femoral condyle’s caudal axial surface to area intercondylaris cranialis of tibia
In EQ: Area intercondylaris Centralis

Lig. cruciatum caudale (21):
from medial femoral condyle’s cranial axial surface to area intercondylaris caudalis and incisura poplitea of tibia

Lig. meniscofemorale (22):
from medial femoral condyle’s caudal axial surface to caudal end of lateral meniscus

Question 5

Synovial, protecting and fibrocartilaginous structures of stifle joint:

Answer 5

Corpus adiposum infrapatellare (7):
- fatty tissue under lig. patellae

Bursa infrapatellaris (8): 
- under lig. patellae at tibial tuberosity

Recessus suprapatellaris (9): 
- behind and above patella

Recessus subextensorius (10): 
- around tendon of m. ext. dig. longus

Recessus subpopliteus (11): 
- around tendon of m. popliteus

Meniscus medialis (12): 
- fibrocartilage between femur and tibia

Meniscus lateralis (13): 
- fibrocartilage between femur and tibia

Fibrocartilago parapatellaris (14): 
around patella, on both sides

Question 6

CAPSULA in EQ:

Answer 6

• Separate cavities (Ø in Ca)
• Some cavities does not communicate.

Femoropatellar = Joint cavity
Communicates with:
Medial cavity=Prox synovial layer –> Distal synovial layer

Femoropatellar = Joint cavity Does NOT COMMUNICATE with:
Lateral cavity = but, Prox synovial layer, communicate with -> Distal synovial layer

Medial and lateral cavity: Prox synovial layer does NOT COMMUNICATE.

Question 7

LIGAMENTS ART. FEMOROTIBIALIS EQ

Answer 7

3* Patellar ligament!!!
1. Mediale
(Fibrocartilagenous) Patella -> Sulcus Tuberositas Tibiae

2. Intermedium
   Patella –> Sulcus Crista Tibiae
3. Laterale
   Fibrocatilagenous patella-> Cranial edge of lat CONDYLE

IMP: LOCK MECHANISM: loop

1. Lig. Patellae MEDIALE
2. Patella
3. Tuberculum Trochlea ossis femoris

Ø LIG. TRANSVERSUS GENUS
Lig. Cruciatum Craniale Inserts on Area intercondylaris centralis (CA: Cranialis)
