In Santos 2025 et al., on feline MPL morphology, which CT variable showed the greatest reduction in affected limbs compared to controls?
🔍 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 İnal 2025 et al., on feline high-rise trauma, what percentage of cats lacked the classic triad of HRS signs (epistaxis, pneumothorax, hard palate fracture)?
🔍 Key Findings
Sample: 373 cats with high-rise syndrome (HRS) from 2017–2020.
ATTS was the only significant predictor of survival (p < 0.001); each point increase decreased survival odds (OR = 0.46).
AUC for ATTS ROC curve: 0.857 (95% CI: 0.788–0.926).
Floor height, lesion type, and ground surface were not significantly associated with survival.
Odds of injury were 7.98× higher when landing on hard vs. soft surface (p < 0.001).
16.96× increased injury risk from the fourth vs. third floor (p = 0.008).
Cats with ATTS ≥7 had 62% mortality; median ATTS increased with floor height (r = 0.244, p < 0.001).
Thoracic and vertebral trauma were most common causes of death.
Only 32% of cats had the “classic” HRS triad (pneumothorax, epistaxis, hard palate fracture).

In Quitzan 2022 et al., on staple line configuration, which FEESA combination demonstrated the highest initial leak pressure (ILP)?
🔍 Key Findings
- All FEESA configurations leaked at lower pressures than intact segments, confirming reduced integrity vs. native tissue.
- FEESA with 3-row transverse staples (3V/3T or 2V/3T) had significantly higher leak pressures than 2-row configurations.
- 3V/3T configuration had the highest ILP (69.88 ± 21.23 mmHg) among all groups, significantly greater than 2V/2T and 3V/2T (P < .001).
- Leakage consistently occurred at the transverse staple line (not vertical), regardless of configuration.
- No significant difference in maximum intraluminal pressure (MIP) between FEESA groups.
- All FEESA constructs withstood intraluminal pressures >25 mmHg, exceeding normal physiological jejunal pressure in dogs.
- No leaks occurred from the vertical staple line, highlighting it as a more robust closure site.
- Third staple row in transverse line may be a viable alternative to suture oversew, pending further clinical evaluation.

In Zingel 2026 et al., on canine ankle replacement approach, what percentage of bone–implant gaps measured less than 1 mm after implantation?
🔍 Key Findings
- A lateral surgical approach can successfully implant a canine total ankle replacement (cTAR) prosthesis with accurate implant orientation and stable joint mechanics.
- Post-implantation angular laxity was greater after the lateral approach (15.5°) than the medial approach (9.5°, p = 0.044), though joints remained within acceptable stability limits.
- External rotational laxity increased after implantation with both approaches (lateral +5.4°, medial +6.7°), suggesting mild postoperative rotational laxity likely related to soft-tissue dissection.
- Implant alignment differed minimally between approaches, with most alignment differences <4°, indicating comparable surgical accuracy.
- Bone–implant interface gaps were small and similar between approaches, with ~96% of gaps <1 mm, indicating excellent implant seating.
- Damage to the short lateral collateral ligament occurred in 4/5 lateral-approach limbs, likely due to its insertion near the talar articular surface.
- Technical challenges with the lateral approach included COR post placement and fibular fragment retraction, sometimes leading to slightly proximal implant milling.
- Clinical implication: A lateral approach is a viable alternative when medial exposure is difficult (e.g., medial implants, fibrosis, or abnormal medial malleolus), though ligament injury risk must be considered.

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 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 Eiger 2024 et al., on NIRFA-ICG in axial flaps, what percentage of CSE flap evaluations led to margin changes based on NIRFA visualization?
🔍 Key Findings
- Caudal superficial epigastric (CSE) flaps were most visible with NIRFA, scoring 4/4 VFP in 97% of evaluations.
- CSE flap margins were altered in 65% of observations after NIRFA, showing the strongest influence on surgical planning.
- Thoracodorsal (THO) and omocervical (OMO) flaps had lower visualization scores, with 60–81% of images scoring below 2.
- Surgeons were 17–25 times more likely to adjust margins for CSE flaps versus OMO or THO based on fluorescence imaging.
- Poor inter-rater agreement was found for OMO (ICC 0.49) and THO (ICC 0.35); CSE had near-perfect agreement, but ICC was low due to uniform high scoring.
- Visualization was affected by flap depth and panniculus, making deeper vessels (OMO, THO) harder to see.
- Surgeons often shortened flap length and reduced flap area when modifying based on NIRFA results.
- Real-time angiosome visualization via NIRFA-ICG may reduce necrosis risk and improve patient-specific APF design.
