🔍 Key Findings

• 65% of stifles with patella luxation and intact CCLs had increased radiographic soft tissue opacity
• Weight and radiographic OA were significantly associated with increased opacity (p = .0029 and p = .0143)
• Each 1 kg increase in weight increased the odds of opacity by 10%
• Grade of patella luxation, age, and muscle atrophy were not significantly associated with increased opacity
• 19% of dogs with long-term follow-up developed a CCL rupture post-patella surgery, 50% of those had opacity at initial presentation
• Radiographic opacity alone should not be interpreted as CCL disease in dogs with patella luxation
• Radiographic findings likely represent effusion or synovial hyperplasia, not CCL pathology
• Arthrotomy was used to confirm CCL integrity at surgery, but arthroscopy could provide better sensitivity

🔍 Key Findings

• Buccal transposition flap provided successful closure of large maxillary lip defects in all 5 dogs
• All flaps survived, with 3 dogs experiencing minor complications (e.g., fistulas, dehiscence) that resolved
• Flap vascularization originated from the angularis oris and superior labial arteries, as confirmed via CT angiography
• Excellent cosmetic and functional outcomes were achieved in all cases
• Ex vivo cadaver study validated flap perfusion, showing consistent contrast filling of key arteries
• Oronasal fistulas occurred in 2 dogs at the palatal incision site, likely due to contact with the mandibular canine tooth
• Mandibular canine coronectomy was performed in 2/5 dogs to prevent flap trauma
• Flap design and commissure positioning were customizable, aiding tension relief and improving outcomes

🔍 Key Findings Summary

• 48 dogs (60 stifles) underwent custom 3D-printed TRP implantation for patellar luxation
• 24 treated with TRP alone; 36 with additional procedures (e.g., DFO, TTT)
• Success rate: 59/60 corrected patellar tracking
• Functional outcome: 57/60 full function, 2 acceptable, 1 unacceptable
• Complication rate: 3 total (2 minor, 1 major recurrence)
• TRP spares cartilage unlike trochleoplasty, offering implant-based ridge augmentation
• No implant loosening or infection observed

🔍 Key Findings

• Study compared 606 dogs (English Bulldogs, French Bulldogs, Pugs) undergoing partial staphylectomy via CO₂ laser, bipolar vessel sealing device (BVSD), or conventional incision.
• Mortality rate: 4.0% (24/606).
• BVSD was associated with significantly increased perioperative mortality compared to other methods (OR = 6.0, 95% CI: 1.3–28.4, p = .023).
• High-grade laryngeal collapse (stage II or III) independently increased mortality risk (OR = 4.6, 95% CI: 1.8–11.8, p = .002).
• No difference in mortality between CO₂ laser and conventional incision techniques.
• CO₂ laser and conventional techniques had similar complication rates.

🔍 Key Findings

• Hybrid implants were used in older, heavier dogs with lower canal flare index (CFI) compared to cementless types.
• CFI <1.8 was associated with higher risk of femoral fracture or stem subsidence with cementless implants.
• Total complication rate was 14%, with catastrophic complications in only 1.5%—lower than reported in other studies.
• No significant difference in complication rates across implant types (BFX, BFX-C, hybrid).
• Femur fractures were rare (2.9%), lower than in prior studies, and successfully managed with cerclage/plate fixation.
• Coxofemoral luxation was the most common complication (8 cases); all occurred within 62 days post-op, mostly resolved with revision.
• Collared BFX stems did not significantly reduce complications, though they may limit stem subsidence.
• An implant selection algorithm was proposed, using age ≥7 years, weight ≥45 kg, and CFI <1.8 to guide cemented vs. cementless stem use.

🔍 Key Findings

Internal fixation (IF) group (n=59):

• Complication rate: 20.3%
• Major complications: 15.3%
• Longer time to discharge if complications occurred (median: 12.5 weeks)

External skeletal fixation (ESF) group (n=36):

• Complication rate: 55.6% (p < .001 vs IF)
• Major complications: 52.8%
• Most common issue: pin tract morbidity

Multivariable analysis:

• Use of IF significantly reduced odds of complications (OR 0.23, p = .004)
• Use of post-op antibiotics associated with increased odds of complications (OR 3.53, p = .028)

Fixation choice influenced by age:

• Older puppies more likely to receive IF (OR 1.25 per week increase in age, p < .001)

Breed & fracture distribution:

• Common breeds: Labrador, Border Collie, Whippet
• Common fracture sites: middle and proximal third of tibia

🔍 Key Findings

• Delayed union occurred in 13.9% of fractures; non-union in 4.6%; mal-union in 0.7%
• Major implant failure increased odds of delayed or non-union by 12.9×
• Surgical site infection increased risk 3.2×; bone grafting (any type) was also associated (OR 3.3)
• Comminuted fractures had 4.2× greater odds of delayed or non-union
• Older age increased risk, with odds increasing by 21% per year
• Radius and ulna fractures in toy breeds were not high risk, contrary to historical belief
• Most non-unions required revision surgery with rhBMP-2 or autograft to achieve union
• Ilium fractures showed 0% delayed/non-union — possibly due to robust muscle envelope

🔍 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

• 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.
