“…For dogs who underwent two separate surgeries in the study, a second surgical identification number was given for each surgery. Surgical methods used in this study were trochlear block recession in combination with capsulorrhaphy and tibial tuberosity transposition [5,6]. A full description of the surgical and anesthetic protocols can be found in S1 Appendix.…”

Characterization of C-reactive protein in dogs undergoing medial patellar luxation surgery

et al. 2020

C-reactive protein (CRP) is a major acute phase protein used to monitor response to treatment during surgical recovery. Depending on the anatomical problem, surgery type and technique, the level of CRP can change drastically. The aim of this study was to describe the changes in CRP and white blood cell (WBC) levels following surgery for medial patellar luxation in otherwise healthy dogs. Twenty-two dogs completed the study. CRP was measured using a commercially available dry chemistry slide on a commercially available inclinic analyser. Analyses were performed using the Wilcoxon Rank Sum test and a mixed effects Poisson regression model. A significant change in CRP levels was found between the pre-anesthetic and 24 hr post-surgical timepoint with a median difference of 92.0 mg/dL (P < 0.001). Though a median drop in the CRP value of 13.9 mg/dL was observed between the 24 hr and 48 hr post-surgical time period, the result was not statistically significant (P = 0.456). Similarly, there was a significant increase in WBC between the pre-anesthetic and 24-hr post-surgical time point (P < 0.001) followed by a significant decrease in WBC between the 24 hr and 48-hr post-surgical time points (P = 0.015). In this study population, CRP levels were observed to aid in monitoring of the overall health of the dogs following surgery for medial patellar luxation. The results of this study suggest that both CRP and WBC values significantly increase by 24 hr but where CRP levels remain elevated through 48 hr post-surgery, WBC showed a significant drop between 24 and 48 hr. Further investigation into the length of time for both CRP and WBC to reach basal levels in this particular type of surgery would be of value to monitor recovery from surgery.

Cranial cruciate ligament rupture is one of the most important diseases in canine orthopedics. Despite the frequent occurrence of the disease and the extensive literature available, there is still controversy about the best treatment method. The aim of this review article is to present a new, more specific approach to treatment selection in dogs with cranial cruciate ligament rupture. Patients are divided into different groups and particular treatment methods are then recommended according to group membership. In order to develop the treatment recommendations, the patient groups were initially defined based on criteria that are important for treatment selection, such as type of cranial cruciate ligament rupture, chronicity, degree of instability, size and weight of the patient, stage of osteoarthritis, the presence of bone deformities, concurrent medial patellar luxation or rotational instability. A detailed literature search was conducted through MEDLINE/PUBMED; CAB Abstracts, Google-Scholar and in conference proceedings abstracts from 1990-2019. Based on the available literature, treatment recommendations were developed for each patient group. These patient group-specific recommendations based on best available evidence are intended to simplify the decision-making process for treatment selection in dogs with cranial cruciate ligament disease.

“…Patellar luxation is one of the most frequent orthopedic diseases in canine hindlimb [1][2][3]. Medial patellar luxation (MPL) occurs at a rate of 75%-80% in affected dogs and lateral patellar luxation (LPL) commonly occurs in large breed dogs [1,4]. Malalignment of the quadriceps mechanism is recognized as the primary cause of patellar luxation [1].…”

Patellofemoral contact mechanics after transposition of tibial tuberosity in dogs

et al. 2020

View full text Add to dashboard Cite

Background: Tibial tuberosity transposition (TTT) causes caudalization of the patellar ligament insertion in canine medial patellar luxation, which can lead to increases in patellofemoral contact pressure. Objectives: The purpose of this study is to confirm the effect of patellofemoral contact mechanics after craniolateral and caudolateral transposition of tibial tuberosity in normal canine hindlimbs. Methods: Craniolateral and caudolateral transposition of tibial tuberosity was performed in 5 specimens, respectively. The pressure was measured in the specimen before TTT, and then in the same specimen after TTT. In this process, data was obtained in 10 specimens. The measurement results were output as visualization data through the manufacturer's software and numerical data through spreadsheet. Based on these 2 data and the anatomical structure of the patellofemoral joint (PFJ) surface, whole measurement area was analysed by dividing into medial, lateral and central area. Results: In craniolateralization of tibial tuberosity, total, medial, central contact pressure was decreased and lateral contact pressure was not statistically changed lateral contact pressure than normal PFJ. In caudolateralization of tibial tuberosity, total, lateral contact pressure was increased and medial contact pressure was not statistically changed than normal PFJ. Although not statistically significant changed, central contact pressure in caudolateralization of tibial tuberosity was increased in all 5 specimens. Conclusions: These results imply that traditional TTT, prone to caudal shift of patellar tendon, can increase retropatellar pressure may lead to various complications and diseases of the stifle joint.
