🔍 Key Findings

Study Design: Case series of 8 dogs with confirmed or suspected PJI after total hip replacement (THR)
Dogs were categorized into:

• Curative intent (CI) group (n=5): short-duration infections, implant retention attempted
• Non-curative intent (NCI) group (n=3): chronic infections, implants scheduled for removal or revision

Success Rate: 7 of 8 dogs had infection resolution, including 4 of 5 in the CI group
Sampling sensitivity:

• Arthroscopic culture success was 80% in the CI group but only 33% in the NCI group
• All explanted implants from NCI group yielded positive cultures

Common isolates: Staphylococcus pseudointermedius (including MRSP), S. epidermidis, Stenotrophomonas maltophilia, and E. coli
Ancillary treatments included:

• Partial synovectomy, high-volume lavage (5–10 L), biofilm-depleting lavage, and/or amikacin-impregnated calcium sulfate beads

Mean follow-up: >1 year (mean 812 days); no signs of recurrence in successfully treated cases
Conclusions: Arthroscopic management of THR infections is feasible and effective in appropriately selected dogs. Success aligns with human literature when infection type is favorable (Type 1, 3, 4). Sensitivity of arthroscopic culture is higher in early/acute infections.

🔍 Key Findings

Population: 29 Boxer dogs and 29 age-matched Labrador Retrievers undergoing TPLO.
Scoring Systems Compared: 5-point vs. 10-point radiographic healing systems.
Healing Scores (Week 8):

• Boxers: 5-point mean = 3.3; 10-point mean = 6.9
• Labradors: 5-point mean = 3.6; 10-point mean = 7.5
• → Statistically significant difference (p = 0.0003 and p < 0.0001)

Osteotomy Gap ≥1 mm (present in 16.4%): Associated with significantly lower healing scores and increased recommendations for additional radiographic follow-up (p < 0.0001).
Observer Reliability:

• Both systems = good interobserver consistency.
• Slightly better intraobserver consistency with the 10-point scale.

Clinical Implication: Boxer dogs may need extended healing time or altered follow-up strategy after TPLO.

🔍 Key Findings

• No significant difference in peak load, failure load, stiffness, or 3 mm gap formation among bone tunnel types.
• Transverse tunnel (TT) constructs had 25% higher yield load than modified tunnels (MT) (P = .027).
• Most common failure mode was suture pull-through (67%), with no significant difference between groups.
• Gap formation ≥3 mm occurred in ~90% of constructs; no significant difference in force needed for gap among groups.
• All bone tunnel techniques (TT, VT, MT) are viable options for CCT reattachment in dogs.
• The 3-loop pulley (3LP) pattern provided strong, uniform repair, with higher loads to failure than previously reported.
• TT constructs showed more tendon distortion at the repair interface during loading.
• Inclusion of accessory tendon may have improved repair strength compared to prior studies using GT alone.

🔍 Key Findings

• Overall closure-related complication rate was 14.1%, lower than previously reported (17–78%).
• No clinically meaningful difference in complication rate between orthopedic wire (17.4%) and suture (11.5%) closure methods.
• Dog size (≥20 kg) was the only significant risk factor associated with increased closure-related complications (p = .01).
• Type of closure (wire vs. suture) did not affect risk, even in larger dogs.
• Suture closure showed a non-significant trend toward fewer complications (mean reduction 2.3%, 95% CI: –9.1% to +4.5%).
• Most complications were mild (62%), with only 10 severe cases requiring surgical revision.
• Infection rate was low (2.7%), and not significantly different between wire and suture.
• Suture closure is a valid alternative to wire, including in large dogs, based on this large, multi-institutional study.

🔍 Key Findings Summary

• Sample: 38 Labrador Retrievers (76 elbows)
• SBCs (subchondral bone cysts):
  • Not found in elbows without OA
• Increased number and size with OA severity:
  • Grade 1: median 3 SBCs
  • Grade 2: 9 SBCs
• Grade 3: 20 SBCs (p < .001)
• Larger SBCs in more severe OA (OR = 1.056, p = .012)
• Locations: 62% humerus, 28% ulna, 10% radius
• 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

🔍 Key Findings

• Zurich mini-cementless THA was successful in 9/10 hips in dogs <4 kg, with no lameness at 52 weeks in completed cases.
• Helsinki Chronic Pain Index significantly improved from a mean of 19.8 to 2.3 at 52 weeks (p = 0.0141).
• Fluoroscopy improved implant positioning, especially in LCPD and HD cases, aiding in accurate reaming and alignment.
• Intraoperative complications occurred in 2/10 cases, including acetabular fractures; one case required discontinuation.
• Prophylactic bicortical screws and reinforcement plates were used in cases with rotational instability or cortical compromise and were effective in preventing loosening/fractures.
• Medial patellar luxation improved postoperatively in one dog, though recurrence was noted later without surgical correction.
• No stem or implant loosening or fracture occurred over a mean follow-up of 24.4 months.
• CT is recommended in preoperative planning, particularly in luxoid hip dysplasia cases with uncertain bone stock.

🔍 Key Findings

• Ectopic ureters in cats are rare, but most are extramural and bilateral.
• Surgical techniques used included ureteroneocystostomy (UNC), neoureterostomy (NU), nephroureterectomy, and cystoscopic laser ablation (CLA).
• All cats showed improvement in urinary continence postoperatively, with 11/12 achieving complete resolution.
• Major complications were rare; one cat developed uroabdomen requiring revision surgery.
• Diagnostic imaging was effective, with abdominal ultrasound diagnosing 8/10 and CT 3/3 cases.
• Short- and long-term complications included urethral spasms, UTIs, stranguria, and rectal prolapse; all were manageable.
• CLA was successful in 2 cats and is noted as a first-time described technique in feline ectopic ureter cases.
• Median postoperative follow-up was 340 days, supporting good long-term outcomes.

🔍 Key Findings

• Survival rates did not differ between immediate (90 min) and delayed (≥5 h) surgical stabilization groups at discharge or 1-month post-op (approx. 80% survival in both).
• Hyperlactatemia at 24 hours post-fluid therapy was significantly associated with in-hospital and 1-month mortality (P = .01 and P = .02).
• Persistent tachycardia during hospitalization was linked to increased 1-month mortality (P = .015).
• Partial gastrectomy was required in ~6–10% of cases, with high associated mortality.
• Preoperative stabilization protocols (trocarization, nasogastric tube) allowed safe surgical delays up to 13.7 hours without impacting survival.
• Degree of gastric torsion differed between groups; more 0° torsions in delayed cases, potentially due to decompression-induced derotation.
• No difference in post-op complications such as arrhythmias, hypotension, or AKI between groups.
• More intra-anesthetic deaths occurred in immediate surgery group, highlighting importance of adequate pre-op stabilization.

🔍 Key Findings

• Customized 3D printed cannulas (3DPCs) significantly reduced surgical time in feline cadaver models (125.6 vs. 95.2 min, p = 0.03).
• Use of 3DPCs resulted in a reduction in instrument collisions (6.8 vs. 2.6, p = 0.03).
• Cannula pullout complications decreased with 3DPCs (10 vs. 2.2 per procedure, p = 0.03).
• 3DPCs were designed at shorter lengths (3 cm), improving intra-abdominal working space in cats.
• No incisional or postoperative complications occurred in the two live feline cases.
• One 3DPC insufflation port broke intraoperatively; resolved by using a male luer lock connector in the next case.
• CO₂ leakage occurred from re-used silicone valves in 2 ports; emphasizing the need for durable valve design.
• Estimated cost per 3DPC was <$5.00, suggesting cost-effective customization for feline laparoscopy.
