🔍 Key Findings

Population: 29 Boxer dogs and 29 age-matched Labrador Retrievers undergoing TPLO.
Scoring Systems Compared: 5-point vs. 10-point radiographic healing systems.
Healing Scores (Week 8):

• Boxers: 5-point mean = 3.3; 10-point mean = 6.9
• Labradors: 5-point mean = 3.6; 10-point mean = 7.5
• → Statistically significant difference (p = 0.0003 and p < 0.0001)

Osteotomy Gap ≥1 mm (present in 16.4%): Associated with significantly lower healing scores and increased recommendations for additional radiographic follow-up (p < 0.0001).
Observer Reliability:

• Both systems = good interobserver consistency.
• Slightly better intraobserver consistency with the 10-point scale.

Clinical Implication: Boxer dogs may need extended healing time or altered follow-up strategy after TPLO.

🔍 Key Findings

• Partial cuneiformectomy (PC) did not increase complication rates compared to multilevel surgery alone (overall complications: PC = 16.3%, non-PC = 19.4%; p = .758).
• Major complication rates were not significantly different (PC = 11.6%, non-PC = 7.4%; p = .482).
• Significant improvement in BOAS grade was observed in dogs undergoing PC (p < .0001).
• BOAS index improved significantly in both groups, with greater median reduction in the PC group (28.5%) than non-PC (20.7%) (p < .0001).
• Low body condition score (BCS <4) was significantly associated with higher complication rates (odds ratio = 0.452; p = .004).
• Hospitalization duration did not differ between groups (median = 1 day; p = .743).
• Mortality was low (3.5%) in the PC group despite more severe airway disease, suggesting the technique is safe even in advanced collapse.
• The technique widened the rima glottidis without damaging surrounding structures, reducing airflow resistance and preserving laryngeal function.

🔍 Key Findings

• 3D-printed cannulas (3DPCs) reduced mean surgical time significantly in cadaveric procedures (125.6 vs 95.2 min, p = 0.03).
• Cannula pullout events decreased from a mean of 10 to 2.2 per procedure when using only 3DPCs (p = 0.03).
• Instrument collisions were significantly fewer with 3DPCs (6.8 vs 2.6 collisions, p = 0.03).
• Live patients experienced no postoperative complications, including no incision site infections or discomfort.
• Initial versions of 3DPCs had minor issues, including valve leakage and looser trocar fit, requiring surgical workarounds.
• Customization of cannula shaft length (3 cm vs standard 5–8.3 cm) improved working space and reduced instrument interference.
• Production cost was under $5 per cannula, suggesting 3DPCs may be a cost-effective and reusable alternative for small patients.
• Study supports broader use of 3DPCs in laparoscopic procedures requiring long-jawed instruments or intricate tissue handling.

🔍 Key Findings:

• Sample: 24 canine cadavers, 477 total pins across 240 vertebrae.
• Technique Comparison: 3D printed guides (3DPG) vs freehand (FH).
• Acceptable Placement Rates: 3DPG = 87.5%, FH = 69.8% (p < .0001).
• Odds Ratio for FH: 0.28 (95% CI 0.16–0.47), significantly less likely to yield acceptable placement.
• Worst Accuracy Locations: T10 (OR 0.10), T11 (OR 0.35).
• Surgeon Impact: Surgeon 2 outperformed others (OR 9.61, p = .001).
• Modified Zdichavsky Classification used to score implant accuracy (Grades I–IIIb).
• Primary Benefit of 3DPG: Increased safety and precision, regardless of surgeon experience.

🔍 Key Findings

• DPO significantly improved femoral head coverage, increasing mean DLS from 36.1% to 71.4% postoperatively (p < 0.001).
• No significant change in DLS between immediate postoperative and follow-up scans, suggesting stable surgical outcomes over time.
• Greater plate angle (30°) yielded larger DLS improvement (mean increase: 39.8%) compared to 25° and 20° plates.
• Only 3 hips had post-op DLS scores <55%, indicating most patients had lower risk of osteoarthritis progression.
• No correlation found between DLS improvement and age, body weight, or side of surgery, suggesting broad applicability.
• CT was used for DLS measurement in simulated weight-bearing, improving precision over radiographic methods.
• Major limitations included small sample size, multiple surgeons, and variable sedation vs anesthesia during imaging.
• DPO confirmed as effective for reducing dorsolateral subluxation, improving coxofemoral joint congruency in dysplastic dogs.

🔍 Key Findings

• Canine unicompartmental elbow (CUE) had the highest reported success (91–98%) and the second-best safety profile (NNH = 7.6).
• Sliding humeral osteotomy (SHO) showed moderate success (43–82%) but had the best safety profile (NNH = 9.5).
• Overall evidence quality was low, with no Level I studies and only five Level II (prospective) studies.
• Success measures were inconsistent, often based on subjective outcomes (e.g., owner satisfaction), limiting comparability.
• Adverse events were common, with high complication rates in arthrodesis and total elbow arthroplasty (TEA).
• One study using objective outcome (PVF) showed only 43% long-term success for SHO, suggesting possible overestimation of success in subjective studies.
• The review highlights the need for validated, standardized outcome tools in elbow OA surgery trials.
• Number needed to harm (NNH) emerged as a more consistent and informative safety metric than success percentages.

🔍 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

• Overall survival to discharge: 107 of 132 dogs (81%)
• Quartile improvement: Survival increased steadily from 67% in Q1 to 91% in Q4
  • Q1: 22/33 survived
  • Q2: 27/33
  • Q3: 28/33
  • Q4: 30/33
• Statistical significance: Higher operative rank significantly associated with improved survival (p < .05)
• Median cross clamp time (XCT): 73 min (range 40–165), but increased again in Q4
• Fatalities (n=25) were often due to:
  • Failure to wean from CPB
  • Intracranial vascular events (stroke)
  • Intrathoracic hemorrhage
• Breed representation: CKCS (23.5%), Chihuahua (22%), Crossbreeds (21%)
• Stages of MMVD: Stage C (67%), Stage D (27%), Stage B2 (6%)
• Emphasis on deliberate multidisciplinary teamwork for outcome improvement
• Highlights importance of technical and non-technical team skills, procedural standardization, and consistent personnel

🔍 Key Findings

• A linear relationship was observed between wedge angle and tibial plateau angle (TPA) correction across all four CCWO techniques.
• All techniques produced predictable TPA corrections using linear regression-derived equations, allowing wedge angle extrapolation to achieve a target postoperative TPA of 5°.
• TLA shift (tibial long axis) increased with wedge angle and influenced final TPA; greatest in Frederick & Cross method.
• Tibial shortening (mTL%) varied by technique, being most severe (up to 40.9%) in traditional Slocum & Devine CCWO and least in newer techniques (7.5–12%).
• The Oxley mCCWO technique showed lower TLA shift compared to the Frederick & Cross and Christ techniques, though similar to Slocum & Devine; tibial shortening was more pronounced than other modified techniques at wedge angles ≤40°.
• Techniques varied in craniocaudal translation and wedge apex positioning, influencing planning accuracy and mechanical axis alignment.
• The corrective wedge angle equations reliably predicted TPA within 4–6° across varied tibial conformations.
• The study supports equation-based planning over static TPA–5° subtraction to reduce risk of under- or over-correction.
