Surgical Stabilization of the Stifle Joint Flashcards
what is a bucket-handle tear?
full thickness tear within the body of the meniscus
what is a radial tear?
full thickness tear from axial free border to periphery
what is the purpose of a meniscal release?
reduce the risk of postliminary tears
what is the function of an intact meniscus?
even pressure distribution
what are some extracapsular surgical options?
lateral suture
fibular head transposition
what is the most common technique performed?
lateral suture
where do you drill for a lateral suture?
tibial tunnel
1cm caudal to patellar tendon
what is the prognosis of lateral suture?
clinical function good to excellent in 90%
how is the plateau segment in TPLO stabilized?
plate fixation
what angle is the tibial plateua in TPLO changed to?
5 degrees
what maintains the advancement in a TTA?
titanium cage
what happens in folding peripheral detachment?
peripheral detachment allows the caudal pole to fold under the femoral condyle
what is an oblique tear?
full thickness tear obliquely through meniscal body
what is a horizontal cleavage tear?
mid-substance cleavage cannot be seen on the surface
what is a hemi-meniscectomy?
removal of the caudal pole
what is a partial meniscectomy?
remove damaged portion and preserve normal meniscus
how common are postliminary meniscal tears?
up to 25%
what does meniscal release do?
mobilizes the caudal pole
which ligament is released in MT ligament release?
caudal meniscotibial ligament
what is intracapsular surgical treatment?
stabilize with an intra-articular prosthesis or tissue
what are the three types of surgeries?
extracapsular
intracapsular
osteotomy procedures
where do you pass the needle in lateral suture?
proximal to fabella, around femoro-fabellar ligament
what does a lateral suture prevent?
cranial tibial thrust and internal rotation
what does tibial plateau leveling osteotomy allow?
angular and rotational alignment of tibia
what angle is the tibial plateau leveled to in tibial plateau leveling osteotomy?
5 degrees
what percentage of TPLOs have good or excellent results?
90%
when does tibial tuberosity advancement neutralize cranial tibial thrust?
at a patellar tendon angle of 90 degrees
