🔍 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

• Case: 9-year-old Labrador with a right caudal pulmonary adenocarcinoma.
• Technique: Peritumoral injection of indocyanine green (ICG) under VATS guidance, followed by near-infrared (NIR) imaging.
• SLN identified: Right tracheobronchial lymph node fluoresced and was safely extirpated.
• Histology: Grade 1 adenocarcinoma, pneumonia, reactive node.
• Outcome: Patient deteriorated and died on postoperative day 3 due to systemic complications (not linked to surgical technique).
• Clinical relevance: First clinical application of SLN mapping for canine pulmonary neoplasia; method feasible with open or minimally invasive approaches.

🔍 Key Findings

• Fewer R1 margins (tumor on ink) were achieved in mast cell tumors (MCTs) when using 6–10 mm lateral margins versus 0–5 mm (7% vs. 55%; _P_ = .049).
• For soft tissue sarcomas (STSs), no benefit was seen in margin completeness between 0–5 mm vs. 6–10 mm lateral margins (41% vs. 43% R1).
• Overall R1 rates were 26% for MCTs and 42% for STSs following PNE.
• R scheme (“tumor on ink” = R1) had better interobserver agreement (83%) compared to ≤1 mm margin criteria (68% agreement).
• Complication rate was moderate (26%), but no surgeries required revision.
• Local recurrence/metastasis occurred in 14% of dogs, with 60% of those having R1 margins.
• Adjunctive therapy was considered clinically indicated in 46% of 0–5 mm margin cases vs. 24% of 6–10 mm cases.
• Histologic grade and tumor size were not predictive of margin completeness.

🔍 Key Findings

• Refracture occurred in 5.5% of limbs, with higher incidence in the plate removal group (12.5%) vs. non-removal (3.5%).
• In the non-plate removal group, refractures occurred at the most distal screw site, linked to greater screw position change during growth (OR 1.79, p=0.04).
• Screw-to-bone diameter ratio (SBDR) >0.4 was a significant risk factor for refracture in the plate retention group.
• In the plate removal group, refractures occurred at the original fracture site, associated with lower pixel value ratio (bone mineral density) and reduced radial thickness.
• Implant-induced osteoporosis (IIO) beneath the plate likely contributed to refracture risk after plate removal.
• Younger age at fracture (<6 months) was associated with higher refracture risk due to ongoing radial growth and shifting screw position.
• No significant association was found between refracture and plate type (locking vs conventional), fixation method, or ulnar union.
• Recommendations include careful SBDR sizing, motion restriction, and cautious plate removal decisions in growing dogs.

🔍 Key Findings

• Bilateral radial head OCD lesions were identified in a 6-month-old English Bulldog with elbow lameness.
• Medial arthroscopic portals allowed only partial visualization of radial head lesions, insufficient for treatment.
• Lateral arthroscopy portals provided excellent access for fragment removal and abrasion arthroplasty.
• Histopathology confirmed OCD, showing cartilage degeneration and retained cartilaginous cores.
• Dog showed complete resolution of lameness and no elbow pain at 5 months post-op.
• Lesions were caudolateral on the radial head, with discoid elevation of cartilage and clefts.
• Lateral approach avoids major neurovascular structures, reducing iatrogenic risk.
• The authors suggest lateral elbow arthroscopy may have broader indications, including for medial compartment disease or synovial biopsies.

🔍 Key Findings

• 15 dogs underwent minimally invasive tarsal arthrodesis (MITA); 10 partial, 5 pantarsal.
• Mean time to radiographic union: 1.8 ± 0.5 months.
• Mean time to clinical union: 3.7 ± 0.8 months.
• Complete osseous union: 46%; the rest achieved ≥50% with functional weightbearing.
• Complication rate: 26% major (mostly implant-related); no catastrophic complications or plantar necrosis.
• Functional outcomes: 6 full, 8 acceptable, 1 unacceptable (not due to MITA).
• MITA may lower soft tissue complications vs open approaches and enable faster healing.

🔍 Key Findings

• Barbed sutures showed comparable leakage pressure to traditional sutures and stapling devices (p = .36).
• No bronchial leaks occurred at physiological pressure (<20 cmH₂O) in any group.
• Leakage at supraphysiologic pressure (20–80 cmH₂O) occurred in 90% of stapler, 80% of traditional, and 60% of barbed suture closures.
• Barbed sutures reduced ligation time significantly compared to traditional sutures (10.7 vs. 14.1 minutes, p < .01).
• Staplers remained fastest, with mean ligation time of 2.4 minutes.
• No knot failure or suture breakage was observed in barbed or traditional suture groups.
• Leakage in barbed sutures occurred mostly at the loop effector zone, but remained within acceptable limits.
• Barbed sutures may offer an effective alternative when staplers are unavailable, impractical, or cost-prohibitive.

🔍 Key Findings

Synovitis was present in 100% of canine stifles with CCL disease (n = 163).

The most frequent severity score was 3/5 (55.2%), followed by 4/5 (24.5%).

Higher synovitis scores were significantly associated with:

• Higher median cartilage scores (p = .042, OR = 2.1 per unit increase)
• Longer duration of clinical signs (p < .001, OR = 1.27 per month)

Bodyweight (p = .083) and sex (p = .17) were not statistically significant in multivariable analysis.

Bucket handle meniscal tears were not associated with synovitis severity.

Clinical implication: Earlier intervention may help reduce synovitis and slow OA progression.
