In Santos 2025 et al., on feline MPL morphology, what best describes the significance of anatomical lateral distal femoral angle (aLDFA) differences?
🔍 Key Findings
Sample: 21 cats (10 control, 11 affected); 14 normal limbs vs 18 with MPL (MPL II: 7, MPL III: 11).
Significantly different CT measurements in MPL vs control:
- aLDFA: MPL II > control and MPL III (p = 0.014)
- FTW: MPL III > control (p = 0.021)
- FTD: control > MPL II and III (p < 0.001)
- TTA: MPL II and III had increased external tibial torsion vs control (p < 0.001)
- fPL and PV: MPL III cats had longer and more voluminous patellae
No significant differences in AA, mMPTA, TTD, fPW, aPH.
Patella width exceeded trochlear width in all groups.
Authors suggest femoral and tibial angular correction may not be indicated in most feline MPL II–III cases.
Soft tissue techniques and trochleoplasty warrant further investigation.
CT method: Intraobserver ICC good in 64%, interobserver poor in 36% of metrics.

In Bae 2025 et al., on SI screw orientation, what was the observed failure mode in all specimens?
🔍 Key Findings
- Ex vivo study using 24 canine cadaver pelves to test screw thread direction in SI luxation.
- Four groups: RhRSI, RhLSI, LhRSI, LhLSI.
- Right-handed screws on right side (RhRSI) had 313% higher torque and 274% higher load vs left side (p < .01).
- Left-handed screws on left side (LhLSI) had 198% higher torque and 195% higher load vs right side (p < .03).
- All failures occurred due to rotation, with no screw breakage or fractures.
- Body weight and moment arm were similar across groups.
- Clinical implication: Use of screw matching handedness to luxation side improves stability.

In Monnet 2023 et al., on barbed vs conventional suture in vesicourethral anastomosis (VUA), what was the key finding regarding leakage pressure?
🔍 Key Findings
- Leakage pressure was not significantly different between unidirectional barbed suture (UBS) and conventional (C) suture groups (p = .236).
- UBS group had a 28% lower median leakage pressure than the C group (8.6 mmHg vs. 11.7 mmHg), suggesting higher biological risk of leakage.
- UBS significantly reduced suturing time (median 12.7 vs. 17.3 minutes; p < .0002).
- Fewer suture bites were needed in the UBS group (median 14 vs. 19; p = .012).
- No suture breakage or urethral narrowing occurred in either group.
- Leakage site distribution (ventral vs lateral) was similar between groups; no dorsal leaks noted.
- Leakage occurred as low as 5 mmHg in UBS group, indicating potential for postoperative extravasation.
- UBS may aid intracorporeal suturing in minimally invasive prostatectomy, but catheterization remains necessary postoperatively.

In Danielski 2025 et al., on PUO complication reduction, what was the **most common major complication** observed?
🔍 Key Findings
- Combined intramedullary (IM) pin and rhBMP-2 use resulted in a low complication rate (7.4%) after proximal ulnar osteotomy (PUO).
- Major complications occurred in 5.3% of cases (4 infections, 1 pin breakage with ulnar tilt requiring revision).
- Minor complications occurred in 2.1% of cases (seroma, delayed union).
- No cases of non-union were observed; 98.9% of limbs achieved radiographic healing by 6 weeks.
- IM pin breakage was noted in 11.8% of limbs but did not affect healing outcomes.
- Chondrodystrophic breeds made up 64.8% of the cohort and tolerated the procedure well.
- Compared to prior studies, complication rates were substantially reduced with this technique (prior major: 13.9%; this study: 5.3%).
- The use of rhBMP-2 likely enhanced early bone healing and provided biologic support, particularly important in breeds at higher risk of complications.

In Israel 2023 et al., on povidone-iodine lavage, which of the following was *not* a complication noted in PrePIL cases?
🔍 Key Findings
- No infections (0/102) occurred in cases where preclosure povidone-iodine lavage (PrePIL) was used, compared to 21/2111 (0.99%) with saline lavage.
- Break-even cost for PrePIL was calculated at $49.74, while the actual cost was only $2.07, confirming strong cost-effectiveness.
- No adverse reactions or healing complications were reported in the 102 PrePIL cases.
- The PrePIL protocol used 0.35% povidone-iodine for 3 minutes before closure, followed by sterile saline lavage.
- Majority of THRs (97%) used cementless fixation (BFX) in PrePIL group; only 3 cases used CFX components.
- Surgeries followed consistent perioperative antibiotic protocols, making PrePIL the only major protocol variable.
- Antibiotics were not added to lavage, aligning with WHO and CDC guidelines for antimicrobial stewardship.
- The infection reduction with PrePIL supports routine use in total hip replacement to reduce periprosthetic joint infections.

In Pfund 2025 et al., on femoral cortical thickness, what was the observed effect of a 0.001 increase in CTI on fracture risk?
🔍 Key Findings
- Lower CTI values were significantly associated with higher risk of both intraoperative and postoperative femoral fractures or fissures (p <.0001).
- The mean CTI for all dogs was 0.285, whereas dogs with fissures/fractures had a mean CTI of 0.246.
- For each 0.001 increase in CTI, odds of fissure/fracture decreased by 2–3% depending on perioperative timing.
- High interobserver reliability (ICC = 0.984) and consistency between pre- and postoperative CTI measurements (ICC = 0.96).
- CTI was the only significant risk factor identified; age, breed, bodyweight, BCS, CFI, or luxoid hips were not significant.
- Prophylactic lateral plating in dogs with low CTI (mean 0.230) resulted in no postoperative fractures.
- Postoperative fractures occurred in 8% of cases, and 93% of dogs returned to full function within one year.
- CTI may be a useful radiographic screening tool, especially when advanced imaging (e.g., DEXA) is unavailable.

In Aldrich 2023 et al., on liposomal bupivacaine in TPLO, what was the reported correlation between CMPS-SF scores and %BWdist?
🔍 Key Findings
- Liposomal bupivacaine (LB) infiltration did not reduce the need for rescue analgesia compared with placebo in dogs undergoing TPLO.
- CMPS-SF pain scores were not significantly different between LB and placebo groups at any postoperative time point.
- % body weight distribution (%BWdist) to the operated limb did not differ significantly between treatment groups across all time points.
- No correlation was found between CMPS-SF scores and %BWdist, suggesting these metrics assess different aspects of postoperative pain.
- Postoperative carprofen administration was standardized, and LB did not provide additional detectable analgesic benefit.
- Three-layer infiltration technique (joint capsule, fascia, subcutis) was used consistently across all cases.
- Adverse events were minor and comparable between LB and placebo groups.
- Post hoc analysis suggested a much larger sample size (58–436 dogs) would be needed to detect significant differences in %BWdist.

In Parlier 2024 et al., on insufflation effects on portal pressure in dogs, what was the average portal pressure increase per mmHg insufflation pressure?
🔍 Key Findings
- Portal pressure increased proportionally with insufflation pressure: 38% at 6 mmHg, 95% at 10 mmHg, and 175% at 14 mmHg.
- Exponential model: average increase of 7.45% per mmHg of insufflation pressure (CI: 4.7–10.2%).
- No systemic hemodynamic adverse effects were observed; MAP remained >60 mmHg throughout.
- Portal hypertension threshold (15 mmHg) predicted at ~6.4 mmHg insufflation pressure.
- No statistical impact from patient weight, pressure-to-weight ratio, or order of insufflation rounds.
- Measurement technique was feasible and safe, with only minor challenges (e.g., catheter kinking).
- The study supports use of the lowest insufflation pressure needed for visualization to avoid portal hypertension.
- Baseline portal pressures returned after desufflation, supporting comparison pre- and post-attenuation.

In McNamara 2022 et al., on transoral endoscopic arytenopexy, which of the following best describes the tissue fixation performed during TEA?
🔍 Key Findings
- TEA significantly increased the rima glottis area (RGA) from a mean of 0.52 cm³ to 0.78 cm³ (p < .0001)
- Mean RGA increased by 157%, equivalent to an 84% estimated decrease in airway resistance
- LEGS (laryngeal epiglottic-glottic seal) remained intact in all cadavers post-procedure, indicating maintained airway protection
- TEA was technically feasible in all 15 cadaveric dogs using a custom endoscopic gag port (EGP)
- TEA avoids cervical dissection, potentially reducing surgical trauma and risks compared to UAL (unilateral arytenoid lateralization)
- Compared to UAL, TEA showed slightly less RGA increase, but greater LEGS preservation, potentially reducing aspiration risk
- No cartilage was included in sutures; arytenopexy involved soft tissue fixation to pharyngeal wall across the piriform recess
- Cadaver model limitations include inability to assess functional outcomes like swallowing and respiratory motion impact
