In Marturello 2023 et al., on 3D-printed humeral models, what general trend was observed regarding the size of the printed models?
🔍 Key Findings
- 3D-printed models using desktop printers (FDM, LFS) showed submillimetric accuracy, comparable to or better than industrial-grade PJP printers.
- Bone size had a greater effect on print accuracy than printer type, especially in proximal humerus regions.
- The humeral condyle region showed the greatest model accuracy, with mean differences under 0.5 mm, regardless of printer.
- Models tended to be slightly smaller than cadaveric bones, potentially due to systematic underestimation during printing.
- FDM printer provided the highest accuracy at the humeral condyle in medium-sized bones (+0.09 mm).
- LFS printer produced prints faster and more reliably than FDM, although both had comparable dimensional accuracy.
- Statistically significant differences existed, but all were submillimetric and unlikely to impact surgical outcomes.
- Desktop printers are suitable for surgical planning, including plate pre-contouring and patient-specific instrumentation.

In Fracka 2024 et al., on perioperative risk factors, which clinical feature had the strongest association with poor recovery outcomes?
🔍 Key Findings
- Staphylectomy was linked to higher risk of complicated recovery than folded flap palatoplasty (OR = 59.29, p = .0002).
- Laryngeal collapse > Grade 2 was strongly associated with poor recovery (OR = 97.13, p < .0001).
- Longer general anesthesia duration increased the risk of complications (OR = 1.01 per min, p = .0051).
- Increasing age significantly raised the odds of perioperative complication (OR = 1.04 per month, p = .0113).
- History of aspiration pneumonia was only found in dogs with complications, though not in final model due to instability.
- Complicated recovery included >12 h O₂ therapy, tracheostomy, or death.
- FFP may reduce pharyngeal-laryngeal edema, possibly improving immediate outcomes.
- Bulldogs comprised 80% of population, with French Bulldogs most common (63%).

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 Mazdarani 2022 et al., on CBLO and stifle biomechanics, the release of the medial meniscus (MMR) led to which of the following?
🔍 Key Findings
- CBLO reduced tibial plateau angle (TPA) from a mean of 28.1° to 9.7°, aligning with its goal of flattening the tibial slope.
- CBLO eliminated cranial tibial translation (CTT) following CCL transection and meniscal release at all angles except 140° without hamstring load.
- Hamstring loading (20% quadriceps load) significantly reduced or delayed the onset of CTT, improving stifle stability.
- Medial meniscus was confirmed as a secondary stabilizer; its release (MMR) caused more CTT than CCLx alone.
- PTA (patellar tendon angle) increased with joint extension; CBLO shifted the PTA curve lower and parallel to intact values, suggesting effective flexion of the joint.
- Combined CBLO and hamstring loading resulted in the most stable joints, especially from 50° to 135° joint angles.
- Residual CTT occurred in CBLO-only limbs at higher extension angles (e.g., 140°), but hamstring load mitigated this.
- Stifle stability post-CBLO is multifactorial, depending on joint angle, meniscal integrity, and hamstring activation.

In Berger 2023 et al., on elbow COR estimation, how might external epicondylar landmarks assist in elbow surgery?
🔍 Key Findings
- COR of elbows with FMCP was significantly more caudal compared to normal elbows, based on CT-derived geometry.
- In normal elbows, 74% of medial and 93% of lateral axes exited cranial and distal to the epicondyles.
- In FMCP elbows, 81% of medial and 70% of lateral axes exited caudal and distal to the epicondyles.
- Different landmark combinations produced slightly different COR approximations, especially between humeral vs. radius/ulna-based axes.
- The medial-lateral axis using trochlea and capitulum centers provided the most consistent COR approximation.
- COR estimations based on diseased elbows may not match normal joint geometry, impacting implant alignment accuracy.
- External epicondylar landmarks may be useful intraoperatively to estimate COR location, but variability limits precision.
- Drill diameter size may buffer small COR differences, but impact in advanced disease or bilateral cases remains unclear.

In Kikuchi 2025 et al., on arthroscopic MMI in toy breeds, what was the overall incidence of medial meniscus injury (MMI) in dogs with CrCLR?
🔍 Key Findings
- Medial meniscus injury (MMI) occurred in 36.3% of stifles with CrCLR in toy breed dogs (<5 kg)
- Complete CrCLR was significantly associated with MMI (15.3% of complete vs. 3.4% of partial)
- Severe lameness (grade 3) increased the likelihood of MMI compared to mild lameness (grade 1)
- Higher body weight, even within the toy breed range, was positively associated with MMI
- Yorkshire Terriers had the highest MMI incidence (55.6%), but this was not a significant independent factor due to multicollinearity
- Arthroscopy identified more meniscal damage (including small radial tears and bucket-handle lesions) than gross examination might detect
- MMI was classified as mild (radial tear) or severe (bucket-handle or flap) with implications for partial meniscectomy
- Arthroscopy was used in all cases, underscoring its utility in small-breed stifle assessment

In Eiger 2024 et al., on NIRFA-ICG in axial flaps, what limitation most affected the visibility of OMO and THO flaps compared to CSE?
🔍 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.

In Moreira 2024 et al., on predictive equations for TPA correction, which of the following is true regarding the Oxley mCCWO technique?
🔍 Key Findings
- A linear relationship was observed between wedge angle and tibial plateau angle (TPA) correction across all four CCWO techniques.
- All techniques produced predictable TPA corrections using linear regression-derived equations, allowing wedge angle extrapolation to achieve a target postoperative TPA of 5°.
- TLA shift (tibial long axis) increased with wedge angle and influenced final TPA; greatest in Frederick & Cross method.
- Tibial shortening (mTL%) varied by technique, being most severe (up to 40.9%) in traditional Slocum & Devine CCWO and least in newer techniques (7.5–12%).
- The Oxley mCCWO technique showed lower TLA shift compared to the Frederick & Cross and Christ techniques, though similar to Slocum & Devine; tibial shortening was more pronounced than other modified techniques at wedge angles ≤40°.
- Techniques varied in craniocaudal translation and wedge apex positioning, influencing planning accuracy and mechanical axis alignment.
- The corrective wedge angle equations reliably predicted TPA within 4–6° across varied tibial conformations.
- The study supports equation-based planning over static TPA–5° subtraction to reduce risk of under- or over-correction.

In Mcclean 2026 et al., on stifle arthrocentesis techniques, which technique was reported as the most commonly used by surveyed surgeons?
🔍 Key Findings
- All four arthrocentesis techniques achieved 100% intra-articular accuracy, confirming that each landmark-guided method could successfully access the canine stifle joint.
- Lateral intercondylar notch (LINC) was the most commonly used technique clinically, reported by 87.5% (35/40) of surveyed surgeons.
- INFRA and SUPRA required significantly more needle repositions (median 3 and 2) compared with LINC and POUCH (median 1) (p = .001).
- No iatrogenic articular cartilage injury (IACI) occurred with LINC or SUPRA techniques, suggesting favorable safety profiles.
- INFRA produced the highest IACI rate (75%), with 6/8 limbs affected, indicating substantial risk with this approach.
- More than half of INFRA injuries exceeded 10 mm² and involved weight-bearing cartilage, raising concern for clinically significant joint damage.
- POUCH technique caused IACI in 37.5% of cases, but injuries occurred exclusively on non-weight-bearing cartilage.
- SUPRA (suprapatellar) approach demonstrated accuracy with zero cartilage injury, making it a promising safer alternative for stifle arthrocentesis pending clinical validation.
