🔍 Key Findings

• Needle arthroscopy (NA) had 95% sensitivity and 100% specificity for detecting medial meniscal tears using standard arthroscopy (SA) as the reference.
• NA correctly identified meniscal status in 25/26 dogs, missing only one stable nondisplaced tear.
• NA took less time than SA: 8 ± 3 min vs. 15 ± 9 min (P = .0041).
• Visibility scores were significantly lower with NA than SA for all meniscal horns (medial and lateral) .
• Probing difficulty was greater with NA, especially for the lateral meniscus (P = .0017).
• NA caused no measurable morbidity: lameness scores were unchanged before and after the procedure (P = .25).
• NA was possible in sedated dogs, though 10/26 required additional anesthesia due to delays.
• NA missed 1 lateral tear, likely due to reduced access and lack of shaving compared to SA.

🔍 Key Findings

• 20.6% of dogs had a preoperative prolongation in PT or aPTT, but only 5.6% had both prolonged.
• Hemangiosarcoma was the only tumor type significantly associated with both PT and aPTT prolongation (37.5% of hemangiosarcoma cases, p < .001).
• Dogs with both PT and aPTT prolongations were 6.5× more likely to have emergency surgery (p < .001) and 2.5× more likely to have hemoabdomen (p = .0022).
• 60% of dogs with both PT and aPTT prolongation required blood transfusion (p < .001).
• Only 1.9% of all dogs had both PT and aPTT prolonged by >25%, suggesting limited clinical utility of routine PT/aPTT testing.
• Platelet count <50,000/μL was rare (1.5%) and not associated with PT/aPTT changes or transfusions.
• Routine PT/aPTT testing offers low diagnostic yield in elective liver lobectomy cases.
• Authors recommend case-by-case PT/aPTT screening, especially when hemangiosarcoma or bleeding tendencies are suspected.

🔍 Key Findings

• CBLO fixation with both a headless compression screw (HCS) and tension band (TB) showed the highest yield and ultimate loads compared to other configurations
• HCSTB constructs had significantly higher yield load (1212 N) and ultimate load (1388 N) than Plate alone (788 N, 774 N), HCS alone (907 N, 927 N), or TB alone (1016 N, 1076 N)
• No difference in construct stiffness was detected among the four fixation methods tested
• All constructs ultimately failed by bone fracture—location of failure differed by construct type (e.g., through HCS hole or cranial screw hole)
• TB and HCSTB groups showed failure via progressive TB stretching and cranial osteotomy widening, while Plate and HCS failed more abruptly
• All constructs withstood forces exceeding expected quadriceps load in vivo (170–325 N), suggesting all methods can resist physiological loading, but HCSTB provides greater safety margin
• HCS alone was not significantly stronger than Plate or TB alone, questioning its standalone superiority
• Study supports using TB and HCS together for optimal construct strength, but clinical studies are needed to validate implant fatigue, healing, and failure rates

🔍 Key Findings

Subject: 7-year-old Labrador underwent cementless total knee replacement (TKR) due to severe stifle OA.

Clinical function:

• Improved ROM from 90° pre-op to 120° post-op.
• Weight-bearing increased from toe-touching to 70% bodyweight by 6 weeks post-op.
• No visible lameness by 14 weeks.

Implant performance:

• No complications at any follow-up points.
• No osteolysis, loosening, or metallosis at 6-year necropsy.

Wear evaluation:

• Mild UHMWPE insert wear, localized to caudal edges.

Histologic findings:

• Robust osseointegration at implant-bone interface.
• Fibrous tissue only in areas lacking porous coating.

Conclusion:

• Cementless TKR demonstrated excellent 6-year survival and functional outcomes.
• Support for considering early surgical intervention in severe stifle OA.

🔍 Key Findings Summary

• Study Design: Retrospective study of 100 radiographs using in silico and clinical data
• Mean preoperative TPA: 28.6°, higher in small dogs than large (p = .02)
• Mean planned TPA (in silico): 7.6°, not achieving 5° target (p < .01)
• Median postoperative TPA: 5.5° overall; higher in small dogs (7°) vs large (4.5°) (p = .06)
• Postoperative ostectomy position: More distal than recommended; average = 8.6 mm
• Increased distalization → greater under-correction of TPA (p = .01)
• Most accurate correction occurred when ostectomy was ≤7.5 mm from patellar tendon
• Wedge angle categories (TPA-Pre minus 5–2°) were used based on pre-op TPA

🔍 Key Findings

• Traumatic pulmonary pseudocysts (TPP) were diagnosed in 11 patients (9 dogs, 2 cats) using CT after blunt trauma.
• TPPs were identified on radiographs in 64% of cases that were CT-confirmed, highlighting the superior sensitivity of CT.
• Most cases (7/10) were managed conservatively, with complete recovery and no TPP-related mortality.
• Thoracic surgery (lung lobectomy) was performed in 3 dogs, due to persistent pneumothorax or large TPP with perceived risk of complications.
• All pneumothorax cases were managed with thoracostomy tubes, and chest drains were used in 73% of cases.
• Pneumothorax was present in 100% of patients, often bilateral, and pulmonary contusions were reported in 73%.
• One cat was euthanized due to unrelated maxillofacial trauma; no deaths were attributed to TPP itself.
• Long-term follow-up (median 768 days) revealed only 1 case with possible TPP-related pneumonia; others had no complications.

🔍 Key Findings

• A positive meniscal flounce sign was associated with normal menisci in 95.5% of cases, demonstrating strong predictive value.
• Absence of the meniscal flounce sign was associated with meniscal tears in 92.7% of cases.
• Overall diagnostic accuracy of the flounce sign was 94.6%, with 96.6% sensitivity and 90.5% specificity.
• Most tears in flounce-negative stifles were bucket-handle tears (73.8%), while radial tears were present in some flounce-positive stifles.
• Radial tears did not consistently eliminate the flounce sign, suggesting they may not disrupt meniscal fiber tension sufficiently.
• All procedures were arthroscopically performed, with probing and visualization of the medial meniscus' caudal pole.
• Flounce sign should complement, not replace, probing—especially as some tear types (e.g., radial) may not abolish the sign.
• Limb positioning and joint distraction may affect flounce visibility, introducing minor observer variability.

🔍 Key Findings

Objective: Determine if topical 45 mg/mL amikacin in CMC gel leads to systemic absorption in dogs with wounds.

Dogs enrolled: 11 client-owned dogs, with 31 applications of the gel.

Serum findings:

• Only 5 of 153 samples were above the 2.5 µg/mL quantification limit
• All values remained <5 µg/mL, the presumed toxicity threshold
• No correlation was found between dose-related parameters (mg, mg/kg, mg/cm²) and serum amikacin levels

Peak concentrations were observed at ~2 hours post-application, declining rapidly thereafter

No nephrotoxicity observed, and most values were below detection

Conclusion: Topical amikacin gel appears safe at doses up to 24.9 mg/kg, with minimal systemic absorption

🔍 Key Findings

• CPAP at 5 cmH₂O via helmet significantly improved PaO₂/FiO₂ ratio in the early postoperative period of brachycephalic dogs, supporting enhanced pulmonary oxygen exchange (p = .04).
• CPAP had no significant effect on SpO₂ (p = .9), PaCO₂ (p = .18), or rectal temperature (p = .5).
• Helmet tolerance decreased over time, with 13 dogs withdrawn for intolerance (9 CPAP, 4 control) and 6 dogs withdrawn for airway compromise (5 control, 1 CPAP).
• CPAP group maintained PaO₂/FiO₂ ratios near or above 400 mmHg, while control dogs showed consistently lower values.
• Authors suggest PaO₂/FiO₂ is a more reliable oxygenation measure than SpO₂ for evaluating postoperative lung function.
• The study found no cases of hyperthermia; temperatures normalized over time in both groups.
• Arterial catheterization failed in several dogs, limiting blood gas analysis to a subset of the population.
• Authors recommend further studies focused on BOAS patients and exploring longer-duration CPAP use to assess impact on critical outcomes like tracheostomy rates or hospitalization.
