In You 2025 et al., on barbed sutures for lung lobectomy, how did the leakage pressure of barbed sutures compare with other techniques?
🔍 Key Findings
- Barbed sutures showed comparable leakage pressure to traditional sutures and stapling devices (p = .36).
- No bronchial leaks occurred at physiological pressure (<20 cmH₂O) in any group.
- Leakage at supraphysiologic pressure (20–80 cmH₂O) occurred in 90% of stapler, 80% of traditional, and 60% of barbed suture closures.
- Barbed sutures reduced ligation time significantly compared to traditional sutures (10.7 vs. 14.1 minutes, p < .01).
- Staplers remained fastest, with mean ligation time of 2.4 minutes.
- No knot failure or suture breakage was observed in barbed or traditional suture groups.
- Leakage in barbed sutures occurred mostly at the loop effector zone, but remained within acceptable limits.
- Barbed sutures may offer an effective alternative when staplers are unavailable, impractical, or cost-prohibitive.

In Lampart 2023 et al., on manual laxity testing, which test showed the greatest interobserver variability in compressive force applied?
🔍 Key Findings
- Cranial drawer (CD), tibial compression (TCT), and tibial pivot compression test (TPCT) showed 100% sensitivity and specificity in differentiating intact from CCL-deficient stifles in this ex vivo model.
- TPCT elicited the highest cranial tibial translation (CTT) and internal tibial rotation, though differences in rotation did not reach statistical significance.
- Inter- and intraobserver agreement for CTT was excellent across all tests (ICC >0.9).
- Rotation and force application had greater variability, particularly with less experienced observers and during CD.
- Forces applied during CD were significantly higher in intact limbs and correlated with observer experience.
- Subjective CTT estimates strongly correlated with objective kinematic measurements (r = 0.895), with a median absolute error of 1.31 mm.
- TPCT may be particularly useful for assessing rotational instability, mimicking the pivot-shift test used in human ACL exams.
- Study supports development of a grading system for manual laxity testing, especially in acute CCLR cases.

In Johnson 2022 et al., on PET implant outcomes, which of the following outcome measures showed statistically significant improvement after surgery?
🔍 Key Findings
- Only 2 of 10 PET implants were fully intact and functional at 6 months post-op.
- Owner-reported function (LOAD scores) improved by 51.7% (p = .008) over 6 months.
- Gait asymmetry improved by 86% (p = .002) postoperatively.
- Implant failure occurred in the midbody of the PET device, suggesting fatigue as a failure mechanism.
- One dog (10%) developed implant infection, necessitating implant removal.
- Implant fixation method (screws + washers + interference screw) was mechanically adequate and technically simple.
- Partially intact implants (4/10) still showed improved clinical outcomes, despite structural compromise.
- Midbody tearing and lack of long-term integrity prohibit continued use of this PET implant in CCL repair.

In Hawker 2025 et al., on locking head inserts, what did the authors conclude regarding high-strain construct scenarios?
🔍 Key Findings
- Adding Locking Head Inserts (LHI) to a 3.5-mm LCP had no effect on plate strain, stiffness, or deformation in an open fracture gap model.
- Peak strain consistently occurred at the Combi-hole over the fracture gap, with values up to ~1837 µε.
- No significant difference in strain was found across configurations with 0, 3, or 9 LHI (p = 0.847).
- Construct stiffness and compressive displacement also remained unchanged regardless of LHI count (p = 0.311 and 0.069 respectively).
- Study contradicted the hypothesis that LHI would reduce strain and increase stiffness under biologic loading.
- Combi-hole design may limit the efficacy of LHI, as LHI only fill the locking portion, not the compression side where strain peaks.
- Implant fatigue risk remains highest over unfilled screw holes, especially over fracture sites—confirming previous failure patterns.
- Surgeons should consider alternative methods to reduce strain when facing high implant load scenarios.

In Miller 2024 et al., on leak testing in cooled feline intestine, what was the finding regarding initial leak pressure (ILP) between fresh and cooled enterotomy constructs?
🔍 Key Findings
- No difference in initial leak pressure (ILP) or maximum intraluminal pressure (MIP) between cooled (17–29 h) and fresh enterotomy constructs.
- Wall thickness of duodenum and jejunum did not differ between fresh and cooled samples.
- Leak locations (suture holes vs clamp sites) were similar between groups; not statistically different.
- Volume of infusion did not influence ILP or MIP outcomes.
- Mean ILP values: Control = 600 mmHg (maxed), Fresh = 200 mmHg, Cooled = 131 mmHg; CE vs FE difference was not significant.
- Intraluminal diameter was largest in the ileum, followed by jejunum and duodenum.
- Cadaveric intestine cooled ≤29h may be reliably used in ex vivo feline leak pressure studies.
- First report of gross small intestinal lengths by region in cats—useful for resection planning.

In Mazdarani 2025 et al., on simulated muscle loading, which model showed the lowest muscle force ratios (quadriceps:gastrocnemius)?
🔍 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 Caldeira 2025 et al., on femoral neck fixation, what role did the 3D-printed guide serve?
🔍 Key Findings
Design: In vitro study on cadaveric femurs (n=21) with basilar femoral neck fractures stabilized using 2 vs 3 titanium cannulated screws.
Stiffness: Control > 3-screw > 2-screw (674 > 120 > 90 N/mm).
Yield Load: 3-screw (586 N) > 2-screw (303 N); both < intact femur (2692 N).
Displacement: No difference across groups.
Complication: 3-screw technique more demanding; higher risk of cortical perforation, especially with narrow femoral necks.
Failure Mode: Dislodgement of femoral head + screw shaft bending.
Conclusion: 3 screws = stronger construct than 2 screws. Clinical implications need further study.

In Saitoh 2025 et al., on CTS stabilization, which group of dogs all returned to work after CTS stabilization?
🔍 Key Findings
Study population: 12 dogs with medial or lateral tarsocrural joint instability (TCI), including 5 working farm dogs.
Procedure: Temporary immobilization using a calcaneotibial screw (CTS) combined with external coaptation (EC).
Stabilization techniques:
- 3 dogs = primary ligamentous repair
- 8 dogs = synthetic ligament reconstruction
- 2 dogs = malleolar fracture repair
Follow-up: Median 31 months (range 4–66); 10 owners completed outcome survey.
Outcomes:
- All 10 dogs had improved or resolved lameness.
- All 5 farm dogs returned to work (most at full or substantial capacity).
- Complication rate: 4 distinct events in 3 dogs (1 major = CTS breakage; 3 minor = bandage-related soft tissue injuries).
Conclusion: CTS + EC provided effective immobilization with low complication rate, and functional outcomes were favorable even in active dogs.
