Objective—To determine the prevalence of lymphoplasmacytic synovitis (LPS) in dogs with naturally occurring cranial cruciate ligament (CCL) rupture and compare clinical, radiographic, cytologic, and histologic findings in dogs with and without LPS.
Animals—110 dogs with naturally occurring CCL rupture.
Procedures—Histologic examination of synovial biopsy specimens obtained at the time of surgical treatment was used to identify dogs with LPS. Clinical, radiographic, cytologic, and histologic findings were compared between dogs with and without LPS.
Results—56 (51%) dogs had histologic evidence of LPS. There were no significant differences in age, body weight, duration of lameness, severity of lameness, severity of radiographic signs of degenerative joint disease, extent of CCL rupture (partial vs complete), or gross appearance of the medial meniscus between dogs with and without LPS. Mean tibial plateau angle was significantly lower in dogs with LPS than in dogs without LPS, and dogs with LPS were significantly more likely to have neutrophils in their synovial fluid. Lymphocytes were seen in synovial fluid from a single dog with LPS.
Conclusions and Clinical Relevance—Results suggested that LPS was common in dogs with naturally occurring CCL rupture. However, only minor clinical, radiographic, cytologic, and histologic differences were identified between dogs with and without LPS.
Objective—To identify risk factors for successful surgical
management of dogs with atlantoaxial subluxation
Animals—46 dogs managed surgically for AAS.
Procedure—Age at onset of clinical abnormalities,
duration of clinical abnormalities prior to surgery,
radiographic appearance of the dens, type (dorsal or
ventral procedure) and number (1 or 2) of surgeries
performed, grade of postoperative atlantoaxial joint
reduction, and neurologic status prior to surgery (preoperative),
when dogs were discharged from the hospital
(postoperative), and during a follow-up evaluation
(final) were obtained from the dogs' medical records.
Risk factors for surgical success and degree of neurologic
improvement were identified and analyzed for
Results—Age at onset of clinical abnormalities ≤ 24
months was significantly associated with greater
odds of a successful first surgery and final outcome
and a lower postoperative neurologic grade. Duration
of clinical abnormalities ≤ 10 months was significantly
associated with greater odds of a successful final
outcome and a lower final neurologic grade. A preoperative
neurologic grade of 1 or 2 was significantly
associated with a lower final neurologic grade.
Potential risk factors that did not affect odds of a successful
outcome included type of surgery performed,
grade of atlantoaxial joint reduction, radiographic
appearance of the dens, or need for a second surgery.
Conclusions and Clinical Relevance—Age at onset
of clinical abnormalities, duration of clinical abnormalities
prior to surgery, and preoperative neurologic status
are risk factors for success of surgical management
of AAS in dogs. (J Am Vet Med Assoc 2000;
Objective—To evaluate the effect of cold compression therapy (CCT) on postoperative pain, lameness, range of motion of the stifle joint, and swelling following tibial plateau leveling osteotomy (TPLO) in dogs.
Animals—34 client-owned dogs with unilateral deficiency of a cranial cruciate ligament undergoing TPLO.
Procedures—Dogs were assigned to 2 groups. Group 1 (n = 17 dogs) received CCT in the 24-hour period following TPLO. Group 2 (n = 17 dogs) received no CCT. Degree of lameness, range of motion, and circumference of the stifle joint were measured before surgery and 1,14, and 28 days after surgery. A modified composite Glasgow pain scale, visual analogue scale, and pain threshold score were used to evaluate signs of pain before surgery and 1,14, and 28 days after surgery. Logistic regression and linear regression analysis were used to compare the measured variables.
Results—No complications were observed, and all dogs tolerated CCT. Use of CCT resulted in lower values for the visual analogue scale and Glasgow pain scale and lower pain threshold scores; lower lameness scores; less swelling; and an increased range of motion 24 hours after surgery. At 14 days after surgery, there were no significant differences between groups. At 28 days after surgery, too few data sets were available for comparison.
Conclusions and Clinical Relevance—CCT decreased signs of pain, swelling, and lameness and increased stifle joint range of motion in dogs during the first 24 hours after TPLO.
