Nicetto et al: Trochlear Ridge Prostheses for Reshaping Femoral Trochlear Ridges in Dogs with Patellar Luxation
Veterinary and Comparative Orthopedics and Traumatology 2, 2024

🔍 Key Findings Summary

  • 48 dogs (60 stifles) underwent custom 3D-printed TRP implantation for patellar luxation
  • 24 treated with TRP alone; 36 with additional procedures (e.g., DFO, TTT)
  • Success rate: 59/60 corrected patellar tracking
  • Functional outcome: 57/60 full function, 2 acceptable, 1 unacceptable
  • Complication rate: 3 total (2 minor, 1 major recurrence)
  • TRP spares cartilage unlike trochleoplasty, offering implant-based ridge augmentation
  • No implant loosening or infection observed

Multiple Choice Questions on this study

In Nicetto 2024 et al., what was the most common complication after TRP implantation?

A. Infection
B. Implant loosening
C. Periarticular fibrosis
D. Patellar luxation recurrence
E. TRP migration

Answer: Periarticular fibrosis

Explanation: Minor complications included grade 1 lameness from periarticular fibrosis; only one case had luxation recurrence.
In Nicetto 2024 et al., how many dogs experienced full functional recovery following TRP implantation?

A. 45/48
B. 57/60
C. 59/60
D. 48/60
E. 36/48

Answer: 57/60

Explanation: Postoperative function was full in 57 of 60 stifles (48 dogs), acceptable in 2, and unacceptable in 1.
In Nicetto 2024 et al., how much of the patellar craniocaudal thickness does the TRP extraosseous component aim to cover in the sagittal plane?

A. 20%
B. 30%
C. 40%
D. 50%
E. 60%

Answer: 40%

Explanation: TRP height was designed to cover 40% of the patellar thickness to optimize tracking.
In Nicetto 2024 et al., what was the success rate of patellar luxation correction using TRP?

A. 95%
B. 98.3%
C. 100%
D. 90%
E. 85%

Answer: 98.3%

Explanation: TRP corrected patellar luxation in 59 out of 60 treated stifles, a 98.3% success rate.
In Nicetto 2024 et al., what key advantage does TRP offer over traditional trochleoplasty?

A. Shorter surgery time
B. Deeper sulcus creation
C. Cartilage preservation
D. Simpler implant technique
E. Lower cost

Answer: Cartilage preservation

Explanation: TRP augments ridge height, avoiding groove cartilage damage typical in trochleoplasty.
