8 - Stifle Disorder Flashcards
Cranial cruciate ligament rupture is most common in what breed
Labrador Rottweiler
Cranial cruciate ligament rupture seen in what types of dogs
Large and overweight
Cranial cruciate ligament rupture is more likely in male or femal
Female
One of the consequences of CCL rupture is
Progression of OA
CCLR
Cranial cruciate ligament rupture
CCLR surgical treatments are associated with
Improved function and stabilitzation of the stifle
C/S of CCLR
Slow degenerative, lameness, pain on passive motion of stifle, joint effusion, thickened joint, cranial drawer instability, meniscal click
What is medial buttress associated with
CCLR
Meniscal click you feel for with what disease
CCLR
CCLR Pathophysiology
Trauma, structural deformity, pre existing degeneration
What are the four land marks of cranial drawer model
Patella, Lateral fablea, tibial tuberosity, fibular head
Medial meniscal injury in CCL Pathogenesis
Firm attachment of medial meniscus to tibia render its susceptible to damage from cranial tibial subluxation along with greater weight bearing
What dogs do not need surgical management of CCL
Cannot tolerate GA, no lameness, no joint effusion
Another name for modified retinacular imbrication
Flo
The modified retinacular imbrication used to prevent
Constant sub lux of tibia
TPLO
Tibial plateau leveling osteotomy
TPLO is best in
Larger dogs
TPLO does
Attempts to overcome the tendency for cranial tibial thrust during weight bearing by changing the angle of teh tibial plateau
With a TPLo the rehab is
Delayed for a period of readjustment
CBLO
Cora based leveling osteotomy
How is CBLO different than TPLO
Osteotomy is distal to the joint
CBLO may be better in what patients
Young - growth plate
Tibial tuberosity advancement
Turn tibial tuberosity to 90 degree angle to result in compression rather than shear force
Stability of the femoropatellar joint depends on
Alignment of quadriceps muscle complex and underlying bone
Medial patella luxation is
Malalignment of the quadriceps complex result in the malrotation of femur and tibia
Most patients with medial patella luxation are born with
Reduced patella that starts to rotate medially
What is Grade 1
Push out physically but goes right back in
What is grade 2 medial patella luxation
Goes out on own but pops back in to own
What is grade 3 medial patella luxation
Luxated but doctor can push it back in
What is grade 4 medial patella luxation
Luxated and cannot be reduced
With grade 4 medial patella luxation what becomes a flexor muscle
Quadriceps
Medial patellar luxation is in what breeds
Toy and mini
Lateral patellar luxation is seen in what breeds
Large, and chondystsropic dogs
With grade 1 medial patella luxation what is the lameness
Little to none
medial patella luxation diagnosis
Palpate tibial tuberosity, feel trochlear groove, ROM
If grade 3 or 4 what surgical treatment could u do
Recession trochleoplasty
medial patella luxation capsulectomy
Remove redundant tissue
medial patella luxation desmotomy
Grade 3 or 4, medial release
medial patella luxation Tenotomy
Grade 4
2 types of recession trocheloplasty
V wedge and block
Which recession trochleoplasty is more common
Block
Tibial tuberosity transposition changes the
Alignment of the extensor mechanism relative to the femoral trochlea
Tibial tuberosity transposition may be used to correct
medial patella luxation and lateral
medial patella luxation capsulectomy
Arthrotomy on redundant side, remove a strip of joint capsule, suture
medial patella luxation desmotoomy
Medial release, incisor of the shortened femoropatellar ligament
