Q

What position should the stifle be during the Tibial Compression Test?

A

Extended! Don’t let it flex

17
Q

What are you looking for on rads? (CCL)

A

Position
Effusion
DJD - Osteophytes
Cranial Tibial Subluxation

18
Q

Where do we see osteophytes on rads?

A

Tibial plateau, trochlear ridges, distal or proximal aspect of patella, fabellae

19
Q

What are the meniscus and what do they do?

A

Paired semicircular fibrocartilages

Provide stability and protects articular cartilage

20
Q

Meniscal tears - _____% incidence secondary to CrCl rupture

A

50-90%

21
Q

Which part of the meniscus is most often injured?

A

Caudal part of MEDIAL meniscus

22
Q

Meniscal injury causes ______. The meniscus must be inspected at ______. What can we do at time of sx of injury is found?

A

significant lameness/pain

time of sx

Partial or hemi-meniscetomy warranted if torn

23
Q

Should we just do a prophylactic meniscal release at time of sx (TPLO or TTA)?

A

Probably not… do it if there is some damage there. Doing a release will cause loss of meniscal fx and alter the contact mechanics. Can also result in lameness and secondary OA.

24
Q

Should we be doing arthroscopy/arthrotomy on these cases?

A

ALWAYS!!!

“More mistakes are made from not looking, as compared to not knowing”

25
Q

Conservative management of CCL Dz

A

Dogs < 15kg acceptable limb fxn

Reported success rates high (84-90%) for these small dogs. Larger dogs have low success rates (<20%)

26
Q

Sx indicated for most dogs with the goals of:

A

Reestablish joint stability
Mitigate secondary DJD
Address any concurrent meniscal injury

27
Q

What about Extraarticular stabilization?

A

Most literature cites good to excellent limb fxn

Long term outcome suboptimal?

  • fail to maintain stability
  • progressive OA
  • does not prevent late meniscal damage
  • no perfectly isometric suture
28
Q

TPLO

A

Decreases tibial plateau slope

29
Q

TTA

A

Altering alignment of the patella tendon

30
Q

How do you decide which sx option to pursue??

A 
O goals, financial constraints 
Pt signalment, activity
Degree of instability 
Tibial plateau slope, limb alignment 
Concurrent patella luxation

*dogs seem to return to normal fxn faster with TPLO and TTA compared to Extracap sx

31
Q

A pt with low patellar tendon insertion is a good candidate for ____

A

TPLO

32
Q

A pt with high patella tendon insertion is a good candidate for ____

A

TTA

33
Q

Whats the post-op care for CCL sx?

A

8 wks house arrest
at 9 wks can begin gradually increasing controlled rehab
Physical therapy! its important

34
Q

Whats the prognosis of CCL sx?

A

All sx techniques quote 80-90% return to ‘normal’ fxn
