🔍 Key Findings

• Needle arthroscopy (NA) had 95% sensitivity and 100% specificity for diagnosing medial meniscal tears in dogs with CCLR.
• NA missed 1 medial and 1 lateral meniscal tear, both nondisplaced and stable.
• Visibility of all meniscal horns was significantly lower with NA compared to standard arthroscopy (SA) (P < .005 for all horns).
• Probing the caudal horn of the lateral meniscus was significantly more difficult with NA (P = .0017), though medial horn probing was similar.
• Mean NA procedure time was 8 ± 3 minutes, significantly shorter than SA (15 ± 9 min, P = .0041).
• No increase in lameness observed after NA, indicating minimal procedural morbidity.
• NA was performed under sedation in most dogs, though 10/26 required additional chemical restraint or short anesthesia.
• NA was most accurate for displaced vertical longitudinal tears, with all 14 correctly identified; one stable tear and a lateral tear were missed.

🔍 Key Findings

• Left pancreaticoduodenostomy successfully restored digestive continuity after right lobe and body pancreatectomy in a cat.
• No clinical signs of exocrine or endocrine insufficiency were observed postoperatively up to 225 days.
• Histopathology confirmed chronic pancreatitis with abscess formation and reactive lymphadenopathy.
• No postoperative pancreatitis developed, based on imaging and normal feline pancreatic lipase levels.
• Progressive focal ampulla-like dilation of the pancreatic duct occurred near the anastomosis without clinical signs.
• The cat maintained weight and improved clinically for several months post-op, indicating satisfactory outcomes.
• Surgical technique involved end-to-side anastomosis between the left pancreatic duct and duodenum.
• Ultimately, the cat was euthanized due to disseminated carcinoma, presumed unrelated to the pancreatic surgery.

🔍 Key Findings

• Simulated quadriceps and gastrocnemius forces increased proportionally with axial load in all three femoral fixation models.
• Model 2 (rigid fixation) resulted in subphysiologic quadriceps forces and abnormally high gastrocnemius forces, reducing model fidelity.
• Models 1 and 3 (with hip mobility) produced more physiologic quadriceps and force ratios, especially under 30–40% bodyweight loads.
• Force ratios were significantly lower in rigid fixation (Model 2) compared to hip-mobile models (p = .007), suggesting model design affects simulated muscle coordination.
• Joint angles (stifle and hock) remained within acceptable limits, though slight flexion occurred with increasing load.
• Relative foot position differed by ~3.9 mm between models 2 and 3, with model 2 showing a more caudal position.
• Model 3 preserved benefits of hip mobility while allowing radiographic documentation, making it a preferred setup for future studies.
• The study suggests that models used in feline stifle stabilization research may underestimate physiologic forces, especially with rigid fixation designs.

🔍 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

• Design: Prospective, randomized, double-blinded controlled trial
• Population: 32 brachycephalic dogs undergoing cut-and-sew sharp staphylectomy
• Groups: Adrenaline + lidocaine (Group A) vs. Lidocaine only (Group NA)
• Main Findings:
  • Total hemorrhage significantly lower in Group A (median 1.82 g) vs Group NA (7.95 g); p = .013
  • Normalized hemorrhage significantly lower in Group A; p = .021
  • Surgeon-assigned hemorrhage scores significantly lower in Group A; p = .029
  • No adverse effects (tachycardia, hypertension, arrhythmia, etc.) noted from adrenaline use
  • Breed effect: English Bulldogs bled more overall even after normalization
• Clinical Implication: Adrenaline in nerve blocks reduces hemorrhage without added risk

🔍 Key Findings

Increased risk with gonadectomy:

• Pooled OR for CrCLD:
  • Females: 2.29 (95% CI: 1.77–2.95)
  • Males: 2.12 (95% CI: 1.67–2.69)

Early gonadectomy (≤1 year) further increased risk:

• OR vs >1 year:
  • Females: 3.39
  • Males: 3.13

Late gonadectomy (>1 year) had no significant difference vs intact dogs.

Breed-specific findings:

• Female Labradors: No increased CrCLD risk from gonadectomy (OR = 1.19; 95% CI: 0.54–2.64)
• Male Labradors: Increased risk persisted (OR = 2.13; 95% CI: 1.53–2.98)

Study type: Systematic review + meta-analysis of 24 observational studies (n = 1.85 million dogs)

🔍 Key Findings

The study included 162 deep-pain-negative dogs undergoing decompressive surgery (hemilaminectomy) for acute thoracolumbar intervertebral disc extrusion (IVDE).

Ambulatory recovery occurred in 53.1% of dogs (86/162).

The best performing machine-learning model was XGBoost, with an AUC of 0.9502 and accuracy of 89.1%, outperforming Ridge, AdaBoost, and Naive Bayes models.

Preoperative-only XGBoost models were less accurate, with AUC dropping to 0.8271 and accuracy to 71.9%.

Top predictive features (by SHAP analysis) included:

1. T2-weighted to L2 spinal cord signal ratio (lower values predicted better outcome)
2. Use of fenestration (presence associated with better recovery)
3. Hospitalization duration
4. Imaging modality used
5. Duration of nonambulatory status

Machine learning provided better insight into prognostic factors than traditional statistical methods.

🔍 Key Findings

• Owner-reported regurgitation improved after CMS, especially post-eating and during activity (P = .012 and P = .002)
• No significant improvement in VFSS measures of SHH or GER postoperatively (P > .05 for all comparisons)
• Laryngeal ventriculectomy and soft palate resection were performed in all dogs, alaplasty in 14/16
• Aspiration pneumonia occurred in 1 dog immediately post-op and resolved with treatment
• Post-op esophagoscopy results varied, with persistent esophagitis in some cases
• Clinical response was variable, with ~25–30% of dogs being “non-responders” based on owner scoring
• 13/16 dogs showed partial or full clinical improvement, despite no change in objective SHH/GER indicators
• Final follow-up at median 36.5 months showed some dogs still on medical therapy; one underwent further surgery

🔍 Key Findings

• Left fourth intercostal thoracotomy allowed successful thoracic duct (TD) ligation in 9/10 canine cadavers.
• 10/13 clinical cases had a single TD branch at the left fourth intercostal space, indicating lower anatomical complexity.
• All TD branches at this site were lateral to the esophagus, simplifying surgical access.
• Unilateral subphrenic pericardiectomy was successfully performed via the same incision in 10/10 cadavers.
• Fewer TD branches at the fourth intercostal space than traditional caudal sites may reduce the risk of missed collaterals.
• In contrast, traditional caudal TD ligation sites had up to 5 branches, requiring broader dissection.
• No cadaver had right-sided TD branches, reducing surgical complexity at the studied location.
• Contrast-confirmed ligation was effective in 90% (9/10) cadavers on CT imaging.

🔍 Key Findings

• Dogs with MPL had significantly shallower femoral trochlear grooves compared to controls, based on CT-measured femoral trochlear groove angle (FTGA).
• FTGA >134° in small breeds (SB) and >128° in medium/large breeds (MLB) were associated with MPL and can serve as surgical thresholds for considering trochleoplasty.
• FTA and FTRIA measurements were less reliable, showing lower sensitivity/specificity than FTGA.
• Inter-rater reliability for FTGA was excellent (ICC > 0.9), supporting its use in clinical decision-making.
• FTGA differed significantly between SB and MLB dogs, suggesting anatomical variation influences MPL predisposition.
• Dogs with MPL but with FTGA below threshold may not benefit from trochleoplasty, supporting individualized surgical planning.
• CT provides more precise and reproducible evaluation of trochlear morphology than radiography or ultrasound.
• The study introduces a CT protocol using P25 and P50 reference points for consistent FTGA measurement.
