In Mazdarani 2025 et al., on simulated muscle loading, which fixation model produced the most physiologic quadriceps forces?
🔍 Key Findings
- Simulated quadriceps and gastrocnemius forces increased proportionally with axial load in all three femoral fixation models.
- Model 2 (rigid fixation) resulted in subphysiologic quadriceps forces and abnormally high gastrocnemius forces, reducing model fidelity.
- Models 1 and 3 (with hip mobility) produced more physiologic quadriceps and force ratios, especially under 30–40% bodyweight loads.
- Force ratios were significantly lower in rigid fixation (Model 2) compared to hip-mobile models (p = .007), suggesting model design affects simulated muscle coordination.
- Joint angles (stifle and hock) remained within acceptable limits, though slight flexion occurred with increasing load.
- Relative foot position differed by ~3.9 mm between models 2 and 3, with model 2 showing a more caudal position.
- Model 3 preserved benefits of hip mobility while allowing radiographic documentation, making it a preferred setup for future studies.
- The study suggests that models used in feline stifle stabilization research may underestimate physiologic forces, especially with rigid fixation designs.

In Longo 2023 et al., on CT trochlear measurements, which statement is TRUE regarding the clinical utility of FTGA?
🔍 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.

In Canever 2022 et al., on labial flap vascular anatomy, which factor is considered most critical for survival of labial musculomucosal axial flaps?
🔍 Key Findings
- Superior and inferior labial arteries in cats perfuse robust angiosomes, which support musculomucosal axial pattern flaps.
- Cadaver angiography confirmed vascular anatomy, with consistent patterns between sides and among specimens.
- The vascular supply is located primarily in the musculomucosal layer, not the skin, critical for flap viability.
- Flap harvest requires inclusion of the orbicularis oris (± buccinator) muscle to ensure vascular integrity and flap survival.
- Two clinical cases demonstrated successful use of superior and inferior labial musculomucosal flaps for palatal reconstruction with complete flap survival and resolution of clinical signs.
- Intraoperative transillumination aided vessel localization, facilitating surgical planning and flap design.
- No cases of distal flap necrosis or dehiscence occurred, although mild donor site morbidity (lip retraction, mucosal denuding) was noted.
- These flaps offer a valuable option when local tissues are compromised, especially after failed previous repairs or radiation therapy.

In Cortina 2023 et al., on modified TTT outcomes for MPL in dogs, which implant-related complication occurred long-term and required management?
🔍 Key Findings
- m-TTT yielded a low overall major complication rate (4.3%) and minor complication rate of 15%, consistent with or better than previous techniques.
- Patellar reluxation occurred in only 4.3% of stifles, with high-grade reluxation seen in just 0.6% of cases—lower than the 12.4–21% range reported for other techniques.
- Implant migration rate was 3.7%, lower than previously reported for smooth pin fixation (7.7–24.6%).
- Use of a tension band with single Steinmann and Kirschner wire reduced stress risers and fixation failure, supporting better stability.
- Tibial tuberosity fracture occurred in only 1.3% of cases, lower than the 1–6% seen in other reports.
- All long-term major complications (1.3%) were related to pin migration, but were easily resolved.
- Radiographic follow-up confirmed complete bone healing in all examined cases, even up to 9 years postoperatively.
- Owner satisfaction was 100%, and 95% rated quality of life as good to excellent based on CBPI surveys.

In Smith 2025 et al., on ergonomic injury risk, which factor was most significantly associated with reporting a work-related musculoskeletal disorder (WRMD)?
🔍 Key Findings
140 laparoscopic surgeons surveyed; 37% reported at least one musculoskeletal disorder.
Women had significantly higher odds of reporting WRMD (OR = 2.59, p = .011).
Smaller glove size significantly associated with WRMD (p = .001), shoulder tendonitis (p = .01), and neck strain (p = .001).
Most common injuries: Neck strain (35%), shoulder tendonitis (31%).
WRMD was associated with greater difficulty using:
- Rotating cup biopsy forceps (p < .001)
- Vessel sealing device and endo stapler (especially in those with shoulder injuries)
No significant association with surgeon age, dominant hand, height, weight, or case volume.

In Thomsen 2024 et al., on CT accuracy for liver tumors, which phase of contrast-enhanced CT was most helpful in localization?
🔍 Key Findings
- CT localization of liver masses was more accurate by division (88%) than by lobe (74.3%)
- Inter-radiologist agreement was excellent for division (kappa up to 0.885) and only moderate–good for lobe
- Quadrate and right lateral lobes had significantly lower localization accuracy compared to left lateral or medial lobes
- CT localization of the left division was most accurate (90.1%) compared to central (77.1%) and right (88.3%)
- Portal and hepatic venous phases were equally helpful for localization (each ~30–38% usefulness)
- No significant associations found between histopathologic diagnosis and localization accuracy
- Lobe-level CT localization should be interpreted with caution, especially for the quadrate and right lateral lobes
- Radiologist experience likely influenced accuracy, with the most experienced radiologist performing best

In Sunlight 2022 et al., on Protein C monitoring, which variable was **not** significantly associated with ultimate clinical status?
🔍 Key Findings
- Postoperative Protein C (PC) activity increased in 78.7% of dogs, and was significantly higher in dogs with excellent clinical outcomes.
- Complete acute shunt occlusion resulted in higher postoperative PC activity (96.3%) and better ultimate clinical outcomes than incomplete occlusion.
- Preoperative PC was not predictive of clinical status, but postoperative PC was associated with improved outcomes.
- Standard biochemical markers (HCT, MCV, ALB, BUN) also improved postoperatively, especially in dogs with excellent clinical outcomes.
- Dogs requiring a second procedure had significantly lower postoperative PC (43.5%) than those not requiring further intervention (78.5%).
- Repeat procedures improved PC and BUN values, with PC increasing significantly after second intervention (to 69.8%).
- PC normalization (within reference interval) occurred in 87.5% of dogs with excellent clinical status, compared to only 12.5% in those with poor status.
- Clinical outcome classification (excellent/fair/poor) correlated with biochemical normalization and lack of need for diet/medications.
