OBJECTIVE: To investigate the incidence of caudal cruciate ligament (CaCL) damage in dogs with cranial cruciate ligament rupture (CCLR). STUDY DESIGN: Prospective clinical study. ANIMALS: Dogs (n=24) admitted for surgical stabilization of the stifle after CCLR and 8 healthy dogs with intact cranial cruciate ligament (CCL) and CaCL studied as controls. METHODS: Preoperative radiographs and stifle joint images (arthrotomy, 6; arthroscopy, 18) were collected from dogs with CCLR. Severity of arthritis, synovitis, CCL damage, and CaCL damage were assessed using numerical rating scales. The CaCL was probed to determine whether minor fraying or a full thickness defect in the ligament was present. Data collected from the study population were compared with the control population of dogs. RESULTS: The CaCL was damaged in 21/24 (88%) of dogs with CCLR; 6/24 (25%) had a full thickness defect in the CaCL. Severity of stifle synovitis and severity of damage to the CaCL were positively correlated (P<.05). CONCLUSIONS: The CaCL is damaged in a high percentage of dogs with CCLR. A significant and positive correlation exists between the degree of synovitis present and the extent of CaCL damage. CLINICAL RELEVANCE: In dogs with CCLR, cruciate ligament pathology typically involves both the CCL and CaCL. As the severity of synovitis and the extent of CaCL damage are related, this observation supports the hypothesis that stifle synovitis may contribute to CCL and CaCL degeneration and subsequent damage.
目的：调查颅侧十字韧带破裂（CCLR）犬尾侧十字韧带（CaCL）损伤的发生率。 研究设计：前瞻性临床研究。 动物：24只因CCLR后接受 stifle关节手术稳定治疗的犬，以及8只颅侧十字韧带（CCL）和CaCL完整的健康犬作为对照。 方法：收集CCLR犬的术前X光片和stifle关节图像（切开术6例，关节镜检查18例）。使用数字评分量表评估关节炎、滑膜炎、CCL损伤和CaCL损伤的严重程度。探查CaCL以确定韧带是否存在轻微磨损或全层缺损。将研究人群收集的数据与犬对照组的数据进行比较。 结果：24只CCLR犬中有21只（88%）的CaCL受损；24只中有6只（25%）的CaCL存在全层缺损。stifle滑膜炎的严重程度与CaCL损伤的严重程度呈正相关（P<0.05）。 结论：CCLR犬中CaCL受损的比例很高。滑膜炎的程度与CaCL损伤的程度之间存在显著正相关。 临床意义：在CCLR犬中，十字韧带病变通常涉及CCL和CaCL。由于滑膜炎的严重程度与CaCL损伤的程度相关，这一观察结果支持了stifle滑膜炎可能导致CCL和CaCL退变及随后损伤的假说。
