obtained in < 60 seconds and generation of
reference values (95% predictive intervals)
for various test durations. Median (95%
predictive interval) 30- and 60-second
STT-1 measurements were 9.1 mm (4.8 to
15.6 mm) and 14.3 mm (8.2 to 22.3 mm),
Conclusions and clinical relevance: The STT1 was a reliable diagnostic test in all settings;
results were not affected by sympathetic
stimulation, and a shorter duration of testing
could be considered in selected cases.
Comparison of liposomal bupivacaine and
0.5% bupivacaine hydrochloride for control
of postoperative pain in dogs undergoing
tibial plateau leveling osteotomy

J Am Vet Med Assoc 256: 1011-1019, 2020; https://
Objective: To compare liposome-encapsulated
bupivacaine (LEB) and (nonliposomal) 0.5%
bupivacaine hydrochloride (0.5BH) for control
of postoperative pain in dogs undergoing tibial
plateau leveling osteotomy (TPLO).
Animals: 33 client-owned dogs.
Procedures: In a randomized clinical trial,
dogs undergoing TPLO received LEB (5.3 mg/
kg [2.4 mg/lb]) or 0.5BH (1.5 mg/kg [0.68
mg/lb]) by periarticular soft tissue injection.
All dogs received carprofen (2.2 mg/kg [1
mg/lb], SC, q 12 h) beginning at extubation.
Signs of pain were assessed at extubation
and predetermined times up to 48 hours
later with the Colorado State UniversityCanine Acute Pain Scale and Glasgow
Composite Pain Scale-Short Form. A pressure
nociceptive threshold device was used at the
affected stifle joint before surgery and at 5
postoperative time points. Methadone (0.1
mg/kg [0.05 mg/lb], IV) was administered if
the Colorado State University pain scale score
was ≥ 2 (scale, 0 to 4). Surgical variables; pain
scores; pressure nociceptive thresholds; times
to first administration of rescue analgesic, first
walk, and first meal consumption; and total
opioid administration were compared between
Results: 28 dogs completed the study.
Dogs administered LEB were less likely to
require rescue analgesia and received lower
amounts of opioids than dogs administered
0.5BH. There were no significant intergroup
differences in other measured variables.
Conclusions and clinical relevance: The
LEB appeared to provide adequate analgesia
after TPLO with lower requirements for opioid
treatments, which may allow dogs to be
discharged from the hospital earlier than with
traditional pain management strategies.
Cranial cruciate ligament disease in cats:
an epidemiological retrospective study of 50

J Fel Med Surg 22: 277-284, 2020; https://doi.
Objectives: The aim of this study was to
describe the characteristics and long-term
outcome of surgically and conservatively
treated cats with cranial cruciate ligament
Methods: A retrospective cohort study of
cats with CCLD, diagnosed at two university
animal hospitals between January 2011 and
December 2016, was performed. Signalment,
history, treatment and follow-up information
were retrieved. Cat owners were contacted
for additional long-term follow-up information.
The cases were divided into two groups: one
conservatively managed and one surgically
treated with the lateral fabellotibial suture
technique. A quality of life questionnaire, the
Feline Musculoskeletal Pain Index (FMPI),
was distributed to the owners of cats alive at
