In Bondonny 2024 et al., what factor contributed to a case of medial patellar luxation at follow-up?
A. Obesity
B. Use of retrograde pinning technique
C. Shortened antirotational pin
D. Late implant migration
E. Premature asymmetric growth plate closure
Answer: Premature asymmetric growth plate closure
Explanation: Medial patellar luxation was linked to angular deformity and early closure of growth plate:contentReference[oaicite:2]{index=2}
In Bondonny 2024 et al., which complication was NOT reported following the surgical technique?
A. Seroma
B. Patellar luxation
C. Osteomyelitis
D. Implant migration
E. Intermittent lameness
Answer: Implant migration
Explanation: No implant migration or removal occurred in any of the 33 fractures:contentReference[oaicite:1]{index=1}
In Bondonny 2024 et al., how did the growth plate appear on radiographs at 6–8 weeks in most cases?
A. Closed in all cases
B. Open in 72.3% of cases
C. Closed in 72.3% of cases
D. Open in 50% of cases
E. Unchanged from baseline
Answer: Closed in 72.3% of cases
Explanation: The physis appeared closed at 6–8 weeks post-op in 72.3% of follow-up radiographs:contentReference[oaicite:4]{index=4}
In Bondonny 2024 et al., which of the following statements is TRUE about antirotational pin placement?
A. It was placed medially
B. It exited through the trochlear groove
C. It crossed only the distal fragment
D. It was always 2 mm in diameter
E. It crossed the intramedullary pin proximal to the fracture
Answer: It crossed the intramedullary pin proximal to the fracture
Explanation: Correct antirotational pin placement required crossing the IM pin proximal to the fracture line:contentReference[oaicite:3]{index=3}

E. 100%
Answer: 96.9%
Explanation: Mid-term full functional outcome was achieved in 96.9% of cats (32/33 fractures):contentReference[oaicite:0]{index=0}
