Q

Articular capsule
strength
incomplete
attached

A

Fairly strong
Incomplete at places where it is replaced by tendonsof surrounding muscle
Attached to margins of articular surfaces
Onlateral side, allows tendon of popliteus muscle to go through
Fibrous capsule is strengthened by ligaments of joint

Q 
Fibular collateral ligament
length
covered by
extends from...
what is deep to it
A

rounded cord like structure 5 cm long
Covered by tendon of biceps femoris
Biceps tendon divides to go onboth sides of ligament
Extends fromlateral epicondyle of femur to head of fibula
Not attached to lateral meniscus
Tendon of popliteus is deep to it

Q 
Tibial collateral ligament
length
crossed by what
Extends from what to what
Tight when
A

broad flat band - 10 cmlong
Crossed by tendons of gracilis, semiten and sartorius
Extends from medial epicondyle of femur to medial surface of tibia
Firmly attached to medial meniscus
Both collateral ligaments become tighter furing extension and stabilize the knee joint

Fibers
Forms part of what
A

Expansion of tendon of semimembranosus
Stengthens post aspect of joint capsule
broad fibrous band with great strength
FIbers go from medial condyle of tibia to lateral condyle of femur
Forms part of floor of popliteal fossa and popliteal vessles rest on it

16
Q

Transverse ligament

A

Conenct two menisci anteriorly

Often abset

17
Q

Anterior and posterior meniscofemoral

A

Trvel obliquely fromlateral menisci to medial femoral condyle

18
Q

Cruciate ligaments

A

Very strong
Cross each other
Named according to tibial attachment

19
Q

Anterior Cruciate ligament

A

Longer but weaker of the two
From ant interchondral fossa to lateral condyle of femur
Stops hyperextension at knee

20
Q

Posteriorcruciate

A

Shorter and stronger
From posterior interchondral fossa to medial condyle of femur
Stops hyperflexion at knee

21
Q 
The menisci of knee joint
Shape
Attached to
Think vs thin area
Funtion
A

2 C shaped lamellae of fibrocartilage
Interposed btw femoral and tibial condyles
Attached to tibial condyles
The peripheral area is thick and attached to capsule via coronary ligament
Inner surface is thin
Their function is to deepen articular surfaces

22
Q

Synovial Membrane

A

lines the articular capsulse

Attached to margins of articular surfaces and to peripheral edges of menisci

23
Q

Nerve supply

A
  1. Femoral
  2. Obturator
  3. Common peroneal
  4. Tibial
24
Q

Blood supply

A

Genicular anastamosis

Middle genicular artery penetrates the capsule and supplies intercodylar structures

25
Q

Movements

A

Flexion - biceps femoris, semitendinosus, semimembranosus

Extension - quadriceps femoris

26
Q

Bakers Cyst

A

Synovial fluid escapes into popliteal fossa

27
Q

Ligament sprains

A

Most common knee injury

28
Q

Unhappy triad

A

Involves the medial collateral ligament, medial meniscus and ACL

29
Q

Anterior drawer sign

A

ACL tear - skiing accident

30
Q

Posterior drawer sign

A

PCL tear - car accident

31
Q

Genu Varum

A

bow leg

32
Q

Genu Valgrum

A

knock knee

33
Q

Bursitis

A

12 bursae around the knee joint

4 communicate with the knee joint
