| clinical signs of a CrCd rupture |
|
Definition
-progressive limp

Term
| Extra-articular repair techniques |
|
Definition
Fascia Lata
Fibular Head Transposition
Lateral Reintinacular Imbrication |
|
|
Term
|
Definition
-tyypically used in conjunction with another technique
-overlapping suture technique to decrease slack out of fascia lata and thereby tighten joint to stabilize it |
|
|
Term
| laterinal retircular imbrication |
|
Definition
-placement of nonaborbsable suture abround lateral fabella to distal third of the patellar ligament
-mimics the orientation of a normal CCL |
|
|
Term
| fibular head transposition |
|
Definition
| -uses collateral and lateral ligament to stabilize joint |
|
|
Term
| Intra-articular techniques for CrCd rupture |
|
Definition
-more common
-Over & Under, TPLO, TTA, TTO |
|
|
Term
|
Definition
-most common association with CrCd rupture
-can sometimes hear a "clicking" sound int he stifle joint as the dog walks |
|
|
Term
|
Definition
-procedures that use ligament/graft pulled thru stifle joint to mimic CrCdL
-joint closed routinely afterwards
-graft will weaken 1st two weekes post-op and then strengthen therafter
-support bandage for 6 weeks |

|
Term
| Tibial Plateau Levening Osteotomy |
|
Definition
-aka TPLO
-requires special equipment/ training
-rotation of tibial plateau to make flatter |
|
|
Term
| Tibial Tuberosity Advancement |
|
Definition
-aka TTA
-vertical cut through proximal tibia that allows the tuberosity to move forward cranially
-changes the slant of the tibial plateau |
|
|
Term
|
Definition
-TTA/TPLO combo
-drops plateau while pushing tuberosity forward |
|
|
Term
|
Definition
-lateral bowing of femur
-internal tibia rotation

Term
|
Definition
-medial bowing of femur
-external tibia rotation
-deep trochlear groove
-hypoplasia of laterial femoral condyle
-more common in large breed dogs |

-deepening of the trochlear groove
-tibial crest transposition
-fabella to tibil tuberosity derotational sutures |
|
|
Term
|
Definition
-fixing a joint to make it immobile
-involves eliminating articular cartilage between bones |
