“…We also did not prove a rise in the risk of medial meniscal damage in relation to the growing joint laxity (measured by radiography in our study). It is in accordance with other papers (D e Rooster et al 1998;Zatloukal et al 2000) which did not prove a difference in the instability of the joint with medial meniscal damage and intact ones. On the basis of our study (and some others) it seems that the grade of joint instability is not a decisive factor for the meniscal damage.…”

“…Regarding the fact that all radiographs were evaluated by one radiologist (Zatloukal), we can consider even these subjective criteria to be uniform and sufficient for our study. Comparing the neutral mediolateral and stress tibial compression projections we determined the index of laxity of the stifle joint using the technique by Zatloukal et al (2000). Stifle joints were classified into three groups (<25, 25-50, >50) using the index of laxity.…”

Risk factors for damage of the medial meniscus in 160 cranial cruciate deficient stifles in 138 dogs have been evaluated. The medial meniscal damage was found in a total of 72 patients (45%) with CCL rupture. The risk of damage to the meniscus was significantly higher in dogs of 25-45 kg compared to those weighing less than 24 kg. Cases of more severe grades of arthritis and joint effusion were significantly more often accompanied by the medial meniscal damage. Severe osteoarthritis of grade 3, as compared to the grade 1, was considerably frequently (p < 0.01) associated with the medial meniscal lesion. The meniscal damage was most commonly accompanied by moderately severe stifle joint effusion. The medial joint cavity collapse was a very important radiographic sign expressing the medial meniscal damage (p < 0.01). Its sensitivity and specifity in the diagnostics of the medial meniscal damage is 52% and 71%, respectively. Duration of lameness, extent of the CCL rupture (partial versus total) and radiographically measured index of the stifle joint laxity do not belong to statistically significant risk factors of the medial meniscal damage.

“…Previous studies evaluating for a distance change in serial radiographs for CTT also have not found a correlation with meniscal status. These studies have had low numbers of cases with meniscal tears (less than 20 total) [5,25]. Our population contained 162 cases with meniscal tears providing stronger support for a lack of correlation and reducing the potential for a type II error.…”

The primary objective of our study was to determine the prevalence of cranial tibial translation on a single unstressed, standing angle, mediolateral radiograph of the stifle and the accuracy of diagnosing complete cranial cruciate ligament rupture in dogs with this finding using a previously published method. The secondary objective was to determine if there was a higher incidence of meniscal injuries associated with spontaneous radiographic cranial tibial translation as previously proposed. Medical records were reviewed for client owned dogs with cranial cruciate ligament rupture that underwent surgical stabilization with intra-operative evaluation of the stifle joint via arthrotomy between June 2013 to January 2022 and had pre-operative radiographs performed within 60 days prior to surgery. Pre-operative radiographs were evaluated for cranial tibial translation via the previously published method. Three hundred twenty-three dogs met the inclusion criteria for the study. Intra-operative findings and radiographic assessments were evaluated for correlations. Cranial tibial translation on pre-operative standing angle radiographs detected cranial cruciate ligament tears in 24.8% of cases but had a positive predictive value of 97.5% for diagnosing complete cranial cruciate ligament rupture with a specificity of 95.4% and an overall accuracy of 36.8%. Meniscal tears were present in 58.75% of cases with radiographic cranial tibial translation and 41.25% of cases without. There was no significant increase in the incidence of meniscal tears between the two groups. The presence of radiographic cranial tibial translation in dogs on an unstressed, standing angle, mediolateral radiograph of the stifle is diagnostic for cranial cruciate ligament rupture, but cannot be used to determine the presence of a meniscal tear.

“…This combination induces deep sedation, sufficient for performing procedures of intermediate level of pain, such as radiography of the hip and stifle joint instability (Neãas and Toombs 1999;Toombs and Neãas 1999;Zatloukal et al 2000). Sufficient analgesia and muscle relaxation is essential for such examinations because it enables measurement of the passive joint laxity.…”

Rau‰er P., L. Lexmaulová: Clinical Comparison of Mmedetomidine-butorphanol and Medetomidine-buprenorphine Combinations for Intravenous Premedication of GeneralAnaesthesia in the Dog. Acta Vet. Brno 2002, 71: 69-76. In this study we compared effects of medetomidine (10 µg/kg) with butorphanol (0.1 mg/kg) and medetomidine (10 µg/kg) with buprenorphine (0.01 mg/kg) used for intravenous premedication of general anaesthesia during surgical procedures in clinical practice. The combination of α-adrenergic substances and opioids induced within 5 min good or moderately good sedation. Anaesthesia was induced by intravenous administration of propofol to achieve loss of laryngeal reflex. General anaesthesia was maintained by a mixture of O 2 /N 2 O/halothane and, at moments of insufficient depth of anaesthesia, it was intensified by propofol re-administration. There was no difference in the dose of propofol for induction of anesthesia between abovementioned combinations used for premedication. The number of re-administrations and the total dose of propofol re-administered, however, were significantly (p < 0.05) lower when premedicating by buprenorphine. We found neither differences in respiratory and heart rates, nor in SpO 2 . We found significant (p < 0.05) differences in ETCO 2 values at the end of anaesthesia, when its concentration was higher in dogs premedicated by the combination of medetomidinebuprenorphine. α-adrenergic drugs, opioids, analgesia, sedation, dog
