To determine the accuracy of needle arthroscopy (NA) for the diagnosis of medial meniscal tears in dogs with cranial cruciate ligament rupture (CCLR).
Prospective clinical trial.
Twenty-six client-owned dogs.
Dogs with CCLR and scheduled to undergo tibial plateau leveling osteotomy were recruited for the study. Needle arthroscopy was performed by an experienced surgeon; the same dog subsequently underwent standard arthroscopy (SA) by another experienced surgeon who was blinded to the NA findings. The SA arthroscopy findings were used as the gold standard. Arthroscopy time, visibility of the menisci, ability to probe the menisci, and the presence of meniscal tears were recorded for both arthroscopies. The degree of lameness before and after NA was subjectively quantified.
The sensitivity and specificity to diagnose medial meniscal tears with NA was 95% and 100%, respectively. Visibility of the menisci was lower (P < .01), probing of the lateral meniscus was harder (P = .0017), and procedure time was shorter (P = .073) with NA when compared to SA. The lameness scores did not differ before and after NA (P = .25).
Needle arthroscopy could be performed rapidly with low morbidity, and had high accuracy for detecting medial meniscal tears in dogs with CCLR.
Needle arthroscopy is a promising minimally invasive technique for diagnosing medial meniscal tears in dogs with CCLR.
确定关节内镜检查（NA）诊断前十字韧带断裂（CCLR）犬内侧半月板撕裂的准确性。
前瞻性临床试验。
26 只患 CCLR 的客户所有犬。
研究纳入了计划接受胫骨平台平整截骨术的 CCLR 犬。由经验丰富的外科医生进行关节内镜检查；同一只狗随后由另一位经验丰富的外科医生进行标准关节镜检查（SA），该医生对 NA 结果一无所知。SA 关节镜检查结果作为金标准。记录两种关节镜检查的关节镜检查时间、半月板的可视性、探测半月板的能力以及半月板撕裂的存在。在 NA 前后对跛行程度进行主观量化。
NA 诊断内侧半月板撕裂的灵敏度和特异性分别为 95%和 100%。与 SA 相比，NA 时半月板的可视性较低（P < .01），探测外侧半月板较难（P = .0017），手术时间较短（P = .073）。NA 前后的跛行评分无差异（P = .25）。
NA 可快速、微创进行，诊断 CCLR 犬内侧半月板撕裂的准确性高。
NA 是一种有前途的微创技术，可用于诊断 CCLR 犬的内侧半月板撕裂。
