(1) Background: Several surgical techniques were described for the treatment of cranial cruciate ligament rupture in dogs. This report aims to critically review the available literature focused on preoperative planning, surgical procedure, follow-up, and complications of cranial cruciate ligament rupture treated by tibial tuberosity advancement techniques; (2) Methods: three bibliographic databases: PubMed, Google Scholar, and Scopus were used for a board search of TTAT (canine OR dog). Five GRADE recommendations according to Grading of Recommendations Assessment, Development and Evaluation and Joanna Briggs Institute Critical Appraisal Checklists were applied to the studies included. Data regarding preoperative planning (a measure of advancement), meniscal disease (meniscectomy, meniscal release, and late meniscal tears), and postoperative patellar tendon angle were recorded. Time frame, outcome, and complications were classified according to Cook’s guidelines; (3) Results: from 471 reports yielded, only 30 met the inclusion criteria. The common tangent method was the most commonly reported measurement technique for preoperative planning. The 40.21% of stifles presented meniscal tears at surgery, while 4.28% suffered late meniscal tears. In short-, mid-and long-term follow-ups examined showed a full/acceptable function was shown in >90% of cases. Among all new generation techniques, minor complications were reported in 33.5% of cases and major complications in 10.67%; (4) Conclusions: Compared to traditional TTA, new generation TTAT resulted effective in the treatment of cranial cruciate ligament failure, showing a lower rate of late meniscal injury but a higher rate of minor complications.

The etiology of spontaneous cranial cruciate ligament rupture in dogs is unknown despite being one of the most impacting orthopedic diseases in dogs. Numerous studies have contributed to the understanding of a multifactorial pathogenesis, this, however, without identifying a pivotal link to explain progressive collagen degeneration and osteoarthritic changes. In human medicine, recent reports have identified relaxin as a triggering factor in ligament ruptures in knee and metacarpal joints. We thus hypothesized that relaxin might also play a role in canine cruciate ligament rupture. Relaxin’s primarily known property is connective tissue remodeling through collagenolysis. We therefore investigated relaxin and its cognate receptors LGR7/LGR8 in 18 dogs with cranial cruciate ligament disease (CCLD) and compared them to a group of dogs with normal stifle joints. Applying immunohistochemistry (IHC), double immunofluorescence (dIF), and western blot analysis (WB), we found strong and significantly increased expression of both relaxin and its receptors in ruptured cruciate ligaments, and in synovial membranes. Pattern of immuno-staining on dIF strongly suggests relaxin binding to primed receptors and activation of signaling properties, which in turn may have affected collagen matrix metabolism. Thus, in canine cranial cruciate ligament disease, relaxin/receptor signaling may be a primary trigger for collagen fiber degradation and collagen lysis, eventually followed by ligament rupture.

Platelet concentrates (PCs) have become widely used in veterinary and human medicine. The PCs consist mainly of supraphysiological concentrations of platelets and, therefore, growth factors (GFs) which are stored within platelet α-granules. Among PCs, Platelet-Rich Plasma (PRP) is characterised by low-density fibrin. Research on the effect of PCs in cattle has surged in recent years; in particular, evidence has shown the positive use of PRP for treating reproductive problems, in vitro production of bovine embryos, sole ulcers and udder diseases. The aim of this report is to critically review, in accordance with the PRISMA guidelines, the available literature reporting clinical application in the bovine practice of PRP. Three bibliographic databases PubMed, Web of Science and Scopus were used for a broad search of “platelet concentrates” OR “PRP” OR “platelet-rich plasma” OR “PRF” OR “platelet-rich fibrin” AND “cows” OR “cattle”. From 1196 papers, only six met the inclusion criteria. Two papers described the use of PRP in mastitis, two papers in uterine dysfunction and two papers in ovarian dysfunction. PRP offered a low-cost, easily obtained therapeutic option and showed positive results for these patients. However, given the different pathologies and definitions involved, further studies are necessary to assess its full clinical potential.

(1) Background: The aim of this prospective study was to evaluate the efficacy of topical application of leukocyte- and platelet-rich fibrin (L-PRF) membranes for treating chronic cutaneous wounds in dogs. (2) Methods: Chronic wounds unresponsive to conventional treatments were assessed on digital photographs and classified using the Bates-Jensen Wound Assessment Tool (BWAT). Each lesion was treated with L-PRF membranes. Epithelialization, granulation tissue formation, wound healing rate, and contraction were statistically analyzed during follow-up. (3) Results: All but one of the cases were treated with a single application of L-PRF for a median of 30 days after onset. All wounds healed after a median of 22 days. The BWAT score, total wound area, and granulation tissue decreased significantly over time while wound contraction increased. The most significant reduction in the total wound area was observed within the first 3 weeks after treatment. None of the dogs required the administration of antibiotics. (4) Conclusions: L-PRF membrane promoted the wound healing process in dogs and is a valuable and cost-effective tool for treating chronic wounds, thereby reducing the need for antibiotics administration.

Hospital-acquired infections in operating rooms are contributing factors to the increasing presence of pathogens, with surgical site infections being the most frequent among them. Surgical antimicrobial prophylaxis is administered to minimize the risk of developing surgical site infection. Surgeons are responsible for weighing the benefit of surgical site infection-risk reduction for the individual patient afforded by prophylactic antimicrobial administration against the broader societal risk from such use. The aim of this study was to analyze the data on surgical antimicrobial prophylaxis related to patient status, surgery duration, wound classification and the occurrence of surgical site infection in two operating rooms of the Veterinary Teaching Hospital of Naples from January 2023 to January 2024. Two hundred seventy-seven surgical procedures met the inclusion criteria. For soft tissue clean-contaminated procedures and clean orthopedic surgeries not involving implants, no statistically significant difference was observed between the various antibiotic protocols used and surgical site infection; this finding supports the possibility of avoiding antibiotic use for these procedures. In contrast to previous reports, this study identified a statistically significant association between ASA status and surgical site infection; no correlation was found between surgical duration and the occurrence of infection. Further research on antibiotic use and risk factors associated with surgical site infection will be crucial to strengthen clinical guidelines.

(1) Background: Lumbosacral traumatic injuries are reported as 39% of canine vertebral lesions. This area is prone to fracture and luxation. Several surgical techniques were described from 1975 to 2021 to stabilize the traumatic injuries of the lumbosacral junction. This report aims to critically review the available literature focused on clinical presentation, surgical techniques, and follow-up of the lumbar vertebra fracture. (2) Methods: Three bibliographic databases: PubMed, Google Scholar, and Scopus were used with a board search of Lumbosacral junction fracture AND, of L7 fracture AND (canine OR dog). The Joanna Briggs Institute (JBI) Critical Appraisal Checklist for case reports and case series was applied for the studies included. (3) Results: A total of 432 reports yielded only nine that met the inclusion criteria. Non-ambulatory paraparesis/plegia, sciatic nerve involvement, faecal/urinary incontinence, and severe back lumbar pain were the most reported signs. Survey radiographs were the most reported technique to confirm the diagnoses. The surgical treatment was reported in all reports examined with a good long-term prognosis. (4) Conclusions: The seventh lumbar vertebra fracture, despite the different surgical techniques performed, had a favourable prognosis for long-term outcome and neurological recovery.
