Evers et al: Accuracy of needle arthroscopy for the diagnosis of medial meniscal tears in dogs with cranial cruciate ligament rupture
Veterinary Surgery 6, 2023

🔍 Key Findings

  • Needle arthroscopy (NA) had 95% sensitivity and 100% specificity for diagnosing medial meniscal tears in dogs with CCLR.
  • NA missed 1 medial and 1 lateral meniscal tear, both nondisplaced and stable.
  • Visibility of all meniscal horns was significantly lower with NA compared to standard arthroscopy (SA) (P < .005 for all horns).
  • Probing the caudal horn of the lateral meniscus was significantly more difficult with NA (P = .0017), though medial horn probing was similar.
  • Mean NA procedure time was 8 ± 3 minutes, significantly shorter than SA (15 ± 9 min, P = .0041).
  • No increase in lameness observed after NA, indicating minimal procedural morbidity.
  • NA was performed under sedation in most dogs, though 10/26 required additional chemical restraint or short anesthesia.
  • NA was most accurate for displaced vertical longitudinal tears, with all 14 correctly identified; one stable tear and a lateral tear were missed.

Multiple Choice Questions on this study

In Evers 2023 et al., on needle arthroscopy for meniscal tears, what was the reported sensitivity for diagnosing medial meniscal tears?

A. 85%
B. 90%
C. 95%
D. 97%
E. 100%

Answer: 95%

Explanation: Needle arthroscopy showed 95% sensitivity and 100% specificity for medial meniscal tear diagnosis.
In Evers 2023 et al., on medial meniscal tear detection, which aspect of the procedure was significantly more difficult using NA compared to SA?

A. Port placement
B. Meniscal probing of the medial horn
C. Shaving of CCL remnants
D. Meniscal probing of the lateral horn
E. Fluid delivery

Answer: Meniscal probing of the lateral horn

Explanation: The caudal horn of the lateral meniscus was significantly harder to probe with NA (*P* = .0017).
In Evers 2023 et al., on needle arthroscopy for meniscal tears, what best describes the procedural morbidity of needle arthroscopy?

A. Mild lameness in most dogs
B. Moderate swelling post-procedure
C. No increase in lameness
D. High rate of infection
E. Requires full anesthesia

Answer: No increase in lameness

Explanation: There was no statistically significant difference in lameness before and after needle arthroscopy.
