In Kennedy 2024 et al., which portal had the highest rate of articular cartilage injury?
🔍 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 Paulick 2022 et al., on feline ilial plating, what factor most contributed to the **poor performance** of the ALPS-5 system despite it being a locking plate?
🔍 Key Findings
- Locking plates (except ALPS-5) withstood significantly more cycles before failure than nonlocking DCP constructs.
- ALPS-6.5, LCP, and FIXIN plates endured higher loads and resisted displacement better than DCP and ALPS-5.
- ALPS-5 plates showed lower bending stiffness than all other constructs (P < .05).
- DCP constructs failed due to screw loosening, seen in all specimens.
- Locking constructs failed by bone slicing, affecting 100% of specimens.
- Catastrophic implant failure (fracture or plastic deformation) occurred only in ALPS-5 group.
- Plate size and screw-plate interface both influence resistance to cyclic loading in feline ilial fracture repair.
- Locking plates are preferable for reducing screw pullout, but plate strength (e.g., cross-section) must match loading forces.

- Sex and Age Effects:
- Older dogs had larger SBCs (p = .013)
- Female dogs had smaller SBCs (p = .002)
- SBC number unrelated to age or sex

In Cherzan 2023 et al., on subcutaneous mast cell tumors, which characteristic was **not** significantly associated with recurrence, DFI, or survival in dogs with subcutaneous mast cell tumors?
🔍 Key Findings
- Local recurrence occurred in 17.8% of dogs, and was associated with significantly decreased survival (551 vs 1722 days, p = .0038).
- Lymph node metastasis occurred in 26.7% of dogs and was significantly associated with shorter disease-free interval (194 vs not reached, p = .0012) and lower survival (551 vs 1722 days, p = .043).
- Mitotic index >7 was significantly associated with higher recurrence (80% vs 22.5%, p = .02), shorter DFI (139 vs not reached days, p < .001), and shorter survival (247 vs 1722 days, p = .05).
- Infiltrative growth pattern was associated with shorter DFI (268 vs 1864 days, p = .011), but not with survival or recurrence.
- Incomplete margins (≤1 mm) were not significantly associated with recurrence (p = .085), but did correlate with shorter DFI (p = .043).
- Chemotherapy or radiation therapy was associated with shorter DFI and survival, likely due to selection bias for more aggressive disease.
- Tumor size >3 cm was associated with decreased survival (p = .031), but not with recurrence or DFI.
- Multinucleation and necrosis were not associated with prognosis outcomes.

In Espinel Rupérez 2023 et al., in Arthroscopic-assisted hip toggle stabilization in cats, what was the median total surgical time for AA-HTS?
🔍 Key Findings
- 14 joints from 7 cat cadavers underwent AA-HTS successfully.
- Median surgical time: 46.5 min (29–144), including 7 min for arthroscopy and 40 min for toggle placement.
- Intraoperative complications in 5/14 joints: 4 related to femoral tunnel creation, 1 toggle lodging.
- Toggle passage through femoral tunnel was the most challenging step, mildly difficult in 6 joints.
- Cartilage injury occurred in 10 joints, but all were minor (<10% of cartilage area).
- 13 deviations from planned technique were identified (8 major, 5 minor), all involving femoral tunnel placement.
- No neurovascular, intrapelvic, or major periarticular injuries occurred.
- Authors conclude: AA-HTS is feasible in cats, but associated with high rates of minor iatrogenic cartilage damage, intra-op complications, and technique deviations.

In Pfund 2025 et al., on femoral cortical thickness, what was the mean CTI for dogs that developed perioperative fractures?
🔍 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 Guénégo 2025 et al., on AMA-based CCWO, what was the surgical site infection (SSI) rate observed?
🔍 Key Findings
- AMA-based CCWO realigned the anatomical and mechanical axes in 82% of dogs >50 kg, with postoperative AMA angle of 0° in most cases.
- Surgical site infection (SSI) rate was only 0.5%, markedly lower than TPLO-reported rates in similar populations (up to 37.5%).
- All osteotomies achieved Grade 4 healing by 8 weeks, with no implant failures.
- AMA-based planning based on preoperative AMA and TPA allowed for better correction of proximal tibial angulation compared to TPLO in large dogs.
- Use of a double locking plate (DLP) fixation and Robert Jones bandage (RJB) contributed to improved mechanical stability and infection prevention.
- Dogs with AMA angle >3.4° (hyper-CCAPT) were 38% of the cohort, supporting AMA as a critical metric in planning.
- Postoperative alignment of the AA and MA was more consistently achieved when preoperative AMA was >2.4°, confirming suitability of AMA-based CCWO for severe angulation.
- Most infections in TPLOs occur within 15 days, but RJB plus antibiotics in this study appeared protective, suggesting benefit for early-phase SSI prevention.

In Horwood 2024 et al., on complications in luxoid hip dysplasia, which intraoperative complication was significantly more common in LH dogs compared to non-LH dogs?
🔍 Key Findings
- Luxoid hip dysplasia (LH) was present in 8% of THA cases and significantly increased risk of major complications (p < .001).
- Intraoperative fissures/fractures were 3x more likely in LH dogs vs non-LH (39% vs 16%, p = .001).
- Dorsal luxation was more frequent in LH dogs (28% vs 4%, p = .019).
- Acetabular cup placement with ALO >35° was associated with luxation in LH dogs.
- Morphologic abnormalities (e.g., femoral valgus, lateralization/medialization of cortices) were common in LH and may complicate implantation.
- Despite higher risk, 94% of LH dogs achieved satisfactory outcomes after appropriate revisions.
- Younger age and lighter weight characterized LH dogs (mean age 14.7 months vs 40.9 months, p < .001).
- All LH dogs were treated with cementless stems; prophylactic cerclage was rarely used.

In Matz 2022 et al., on stapler size comparison, which stapler group had the highest mean initial leak pressure (ILP)?
🔍 Key Findings
- No significant difference in initial leak pressure (ILP) among TA 30 V3 2.5 mm, TA 60 3.5 mm, and TA 60 4.8 mm stapler sizes (P = .78).
- All stapler types exceeded the physiological intraluminal pressure threshold (~25 mmHg), suggesting acceptable leak resistance.
- Mean ILPs: TA 30 V3 (181.5 mmHg), TA 60 3.5 mm (112 mmHg), TA 60 4.8 mm (77.2 mmHg).
- Leakage occurred at the staple line in 23 of 24 specimens; only one had ileal wall rupture.
- No correlation found between ILP and cadaver weight, cecal wall thickness, or cecal length.
- Cecal wall thickness averaged 4.9 mm, yet staple heights ranged only from 1.0–2.0 mm.
- One specimen in each TA 60 group leaked near or below physiologic pressures, suggesting rare outliers.
- Study supports clinical viability of all tested stapler sizes for canine typhlectomy, but highlights need for in vivo data on healing and complications.
