In Schmutterer 2024 et al., what was the observed peak pressure in the lateral meniscus at 125° flexion?
🔍 Key Findings Summary
- Biomechanical study on 14 hindlimbs from Retrievers (cadaveric)
- Three stifle flexion angles tested: 125°, 135°, and 145°
- Contact Force Ratio (CFR) was significantly higher at 125° and 135° than at 145° (p < 0.001)
- Center of force shifted caudally with increasing flexion — especially in medial meniscus
- Lateral meniscus peak pressure was significantly higher at 125° than 145° (p = 0.049)
- Mean pressures on lateral meniscus decreased with extension, while medial meniscus pressure remained constant
- Relevance: Helps interpret meniscal load in early cruciate disease and in surgical modeling

In Heikkilä 2024 et al., on COPLA scaffold evaluation, which adverse event was observed in the COPLA group?
🔍 Key Findings Summary
- 22 dogs (36 shoulders) with shoulder OCD randomly assigned to COPLA scaffold (n=19) or Control (n=17) group
- At 6 months: Significantly fewer dogs in COPLA group had OA (14% vs. 67%; p = 0.019)
- At 1.5 years: OA prevalence increased in both groups with no significant difference (COPLA: 64%, Control: 60%)
- HCPI (pain index) increased significantly at 1 week post-op in COPLA dogs only (p = 0.001), but later normalized
- Static weight-bearing improved only in unilaterally operated COPLA limbs (p = 0.015)
- One dog in COPLA group had a fragment dislodge requiring arthroscopic removal
- Overall, COPLA scaffold may provide short-term benefit in OA reduction, but long-term outcomes were similar

In Dobberstein 2022 et al., on NSAID ulcer repair, what percentage of dogs survived to discharge following primary closure of full-thickness gastroduodenal perforations?
🔍 Key Findings
- Primary repair of NSAID-associated full-thickness gastroduodenal ulcers was successful in 73% (8/11) of cases.
- NSAID overdose, concurrent corticosteroid use, or extended duration were identified in 9/11 dogs and were major contributors to ulceration.
- All perforations were in the pylorus or proximal duodenum, locations suitable for primary closure.
- No significant association between ulcer size or location and postoperative survival.
- Preoperative hyperlactatemia trended toward increased mortality (P = .0544; OR 2.045).
- Postoperative vasopressor use was linked with a 9-fold increased risk of mortality (P = .0545).
- Dehiscence was rare, suspected in only 1 of 11 cases, indicating that primary repair is structurally sound in selected cases.
- Median follow-up of 444 days showed long-term survival was achievable post-primary repair.

🔍 Key Findings
- Ectopic ureters in cats are rare, but most are extramural and bilateral.

- All cats showed improvement in urinary continence postoperatively, with 11/12 achieving complete resolution.
- Major complications were rare; one cat developed uroabdomen requiring revision surgery.
- Diagnostic imaging was effective, with abdominal ultrasound diagnosing 8/10 and CT 3/3 cases.
- Short- and long-term complications included urethral spasms, UTIs, stranguria, and rectal prolapse; all were manageable.
- CLA was successful in 2 cats and is noted as a first-time described technique in feline ectopic ureter cases.
- Median postoperative follow-up was 340 days, supporting good long-term outcomes.

In Kennedy 2024 et al., what was the closest average distance of the caudal portal to a major neurovascular structure?
🔍 Key Findings Summary
- 20 shoulders from 11 medium-to-large breed dogs evaluated
- Lateral portals used: middle arthroscopic, caudal instrument, cranial egress
- Musculotendinous lesions unavoidable, but small (18G needle); seen in deltoideus (90%), infraspinatus, teres minor, etc.
- Neurovascular safety:
- Caudal portal was closest to axillary artery/nerve branches (as close as 7 mm)
- Only 2/20 shoulders (10%) had omobrachial vein penetrated
- Cartilage injuries (IACI) occurred in 65%, primarily minor linear defects; use of guarded cannulas and distractors suggested for minimization
- Supports overall safety of lateral shoulder arthroscopy with portal placement awareness

In Berger 2023 et al., on elbow COR estimation, what was the most common exit location of axes in *normal* elbows on the lateral cortex?
🔍 Key Findings
- COR of elbows with FMCP was significantly more caudal compared to normal elbows, based on CT-derived geometry.
- In normal elbows, 74% of medial and 93% of lateral axes exited cranial and distal to the epicondyles.
- In FMCP elbows, 81% of medial and 70% of lateral axes exited caudal and distal to the epicondyles.
- Different landmark combinations produced slightly different COR approximations, especially between humeral vs. radius/ulna-based axes.
- The medial-lateral axis using trochlea and capitulum centers provided the most consistent COR approximation.
- COR estimations based on diseased elbows may not match normal joint geometry, impacting implant alignment accuracy.
- External epicondylar landmarks may be useful intraoperatively to estimate COR location, but variability limits precision.
- Drill diameter size may buffer small COR differences, but impact in advanced disease or bilateral cases remains unclear.

In Takagi 2022 et al., on hepatic venous anatomy, which liver lobe consistently showed a single hepatic vein draining into the caudal vena cava or via the left hepatic vein?
🔍 Key Findings
- Hepatic venous drainage patterns vary widely across all lobes, especially the left lateral lobe.
- Right lateral lobe had a median of 2 vessels draining directly into the caudal vena cava (CVC); range: 1–4.
- Caudate process of caudate lobe had the most variability: 1–5 vessels draining into the CVC; 2 vessels was most common (54.5%).
- Left lateral lobe drained via 2–8 veins into the left hepatic vein (LHV), with 3 veins most common (31.2%).
- Left medial lobe typically had 1 vein draining into the LHV (61% of dogs).

- Quadrate lobe always had 1 vessel draining either directly to the CVC or via the LHV.
- CTA revealed more variations than previously described in plastinated or cadaveric studies, highlighting its superior value in surgical planning.

In Adams 2022 et al., on C-section survival rates, what was the overall neonatal survival to hospital discharge for all breeds combined?
🔍 Key Findings
- Neonatal survival to discharge was 93.1% overall, with no significant difference between brachycephalic (94.8%) and nonbrachycephalic (91.8%) breeds.
- Elective C-section significantly improved neonatal survival (99.2%) compared to emergency C-section (87.1%) (p < .001).
- Larger C-section litter size was positively associated with survival (p = .004; OR 1.57), whereas total litter size had no effect.
- Maternal heart rate and stage of labor were associated with neonatal mortality in univariable analysis, but not multivariable.
- Brachycephalism alone was not a risk factor for neonatal mortality (p = .221) in multivariable analysis.
- Emergency C-section was the strongest predictor of neonatal mortality (OR 4.75), regardless of breed.
- Multidisciplinary team approach likely contributed to high survival rates, emphasizing importance of coordinated care.
- Historical factors such as primiparity and maternal age were not associated with mortality in this cohort.
