🔍 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.

🔍 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.

🔍 Key Findings

• 3D-printed patient-specific guides (PSGs) improved tibial cut alignment in the frontal plane compared to generic guides (mean error 1.03° vs 2.41°, p = .036).
• All tibial cuts using PSGs were within 3° of target alignment, while 2/8 of the generic group were outliers.
• PSGs significantly improved sagittal alignment of both distal (p = .018) and cranial (p = .043) femoral cuts.
• No significant difference was found in varus-valgus femoral alignment or closing angle between PSG and generic guide groups.
• Tibial sagittal slope alignment was not significantly different between groups.
• PSGs provided better intraoperative usability, including improved visibility, no loosening, and ease of use.
• Femoral sizing and component fit were equivalent between PSGs and generic guides, ensuring proper prosthesis alignment.
• PSGs may offer training advantages for novice surgeons, especially in anatomically complex or deformed joints.

🔍 Key Findings

• FFP resulted in longer median surgery (75 min) and anesthesia (111 min) durations than S (51 min and 80 min, respectively).
• No significant difference in anesthetic complications, regurgitation, aspiration pneumonia, or hospitalization time between S and FFP.
• Major complications were rare (4%) and equally distributed between procedures; included tracheostomy and euthanasia due to severe airway disease.
• Postoperative oxygen use was common (52% of dogs) but not significantly different between procedures.
• FFP dogs more often had laryngeal collapse (especially Grade 1: 68% vs. 32% in S dogs).
• Most dogs (85%) had concurrent nares surgery, with caudal wedge resection more frequent in FFP dogs.
• Few dogs needed revision soft palate surgery (7/124 total); similar between groups.
• Postoperative clinical signs improved across both procedures; regurgitation was the most persistent sign post-op.

🔍 Key Findings

• Ala vestibuloplasty significantly reduced normalized pulmonary transit time (nPTT) (mean 5.43 → 3.89 sec; p <.001), suggesting improved cardiopulmonary function.
• Clinical respiratory signs improved, including reduced snoring, sneezing, nasal discharge, and open-mouth breathing (all p <.01).
• Activity tolerance increased, with less dyspnea during activity and longer time to onset of dyspnea (p <.005).
• Paradoxical sternal motion resolved in all affected cats after surgery.
• Hiatal hernias resolved in 75% of affected cats on follow-up CT.
• No serious complications occurred, with only mild, self-limiting epistaxis and hypersalivation in a few cases.
• Aberrant turbinates were detected on CT in all cats, though only 1 showed obstructive CATs endoscopically.
• Total clinical severity scores improved significantly postoperatively (median reduction of 30 points; p <.001).

🔍 Key Findings Summary

• Study of 24 stifles in 22 dogs with concurrent CCLR and grade III–IV MPL treated via TPLO-TTT
• Major complications: 4/24 (3 surgical site infections, 1 MPL reluxation); minor complications: 5/24
• Long-term follow-up (median 27 months): 21/22 dogs sound, 23/24 stifles resolved
• Patellar ligament thickening observed post-op in 4 cases, resolved with rehab
• The only case of MPL reluxation involved untreated tibial torsion, suggesting case selection is critical

🔍 Key Findings

Design: Ex vivo cadaver study (n=8 dogs, 24 sites)
Comparison: Freehand vs. 3D-printed drill guide-assisted ventral slot (GAVS vs FHVS)
Findings:

• GAVS produced slots not significantly different from planned dimensions (p = .722–.875)
• FHVS produced significantly shorter slots than intended (p < .01)
• No difference in surgical time (p = .071)
• Shape ratio and slot divergence from midline were similar between groups (p > .4)
• Use of guide significantly reduced variability in slot position (63% → 29%), shape (65% → 24%), and divergence (54% → 50%)

Conclusion: 3D-printed guides improved accuracy and consistency of ventral slot creation by novice surgeons; supports future evaluation in live dogs and small breeds

• Three stifle flexion angles tested: 125°, 135°, and 145°
• Contact Force Ratio (CFR) was significantly higher at 125° and 135° than at 145° (p < 0.001)
• Center of force shifted caudally with increasing flexion — especially in medial meniscus
• Lateral meniscus peak pressure was significantly higher at 125° than 145° (p = 0.049)
• Mean pressures on lateral meniscus decreased with extension, while medial meniscus pressure remained constant
• Relevance: Helps interpret meniscal load in early cruciate disease and in surgical modeling

🔍 Key Findings

• Open face version was significantly greater than truncated face version by 14°–22° (p <.001).
• Open face version increased linearly with inclination and pelvic extension, while truncated face version remained largely stable.
• Truncated face version is an unreliable surrogate for open face version.
• Accurate interpretation of cup version should include both truncated face version and inclination.
• Canine 3D pelvic model and CT-based simulation used for all measurements.
