Abstract：
OBJECTIVE: To evaluate the feasibility of feline diagnostic coxofemoral arthroscopy.
METHODS: Ex vivo feline cadaveric descriptive study.
METHODS: Seven feline cadavers (14 hips).
METHODS: Gross dissection of two feline hips was performed to evaluate anatomic landmarks, guide arthroscopic portal development, and determine optimal limb positioning. A 1.9 mm, 0° arthroscope, inserted through a supratrochanteric lateral portal, was used to assess intraarticular structures in 12 feline cadaver hips. Arthroscopy was followed by gross dissection of periarticular soft tissues. Relative portal locations and damage to periarticular structures were recorded. Hips were disarticulated, and an India ink assay was performed to assess whether there was iatrogenic cartilage injury (ICI).
RESULTS: Scope insertion was achieved in all hips. Articular cartilage of the femoral head and acetabulum, round ligament, joint capsule, transverse acetabular ligament, and dorsal acetabular rim were identified arthroscopically in all hips. Probe insertion and intra-articular structure palpation was achieved in all hips. Scope and instrument portals resulted in minimal periarticular muscle trauma. No sciatic nerve damage was detected. Minor partial thickness ICI was observed in all hips at the site of scope insertion. Focal full thickness ICI was noted in one hip.
CONCLUSIONS: Arthroscopy of the feline coxofemoral joint allowed visual and probe evaluation of intra-articular structures without evidence of major periarticular neurovascular trauma. Iatrogenic cartilage injury occurred in all hips but severity of lesions was considered mild.
CONCLUSIONS: Coxofemoral arthroscopy is feasible in cats and can be utilized as a diagnostic tool for minimally invasive joint evaluation.

摘要：
目的：评价猫科动物关节镜诊断的可行性。
方法：离体猫科动物尸体描述性研究。
方法：7具猫科动物尸体（14髋）。
方法：对两个猫科动物臀部进行大体解剖以评估解剖标志，引导关节镜门静脉发育，并确定最佳的肢体定位。1.9毫米，0°关节镜,通过股骨转子上外侧门插入，用于评估12只猫科动物尸体臀部的关节内结构。关节镜检查后进行关节周围软组织的大体解剖。记录门静脉的相对位置和关节周围结构的损伤。臀部脱节，并进行印度墨水测定以评估是否存在医源性软骨损伤（ICI）。
结果：在所有臀部均实现了范围插入。股骨头和髋臼的关节软骨，圆韧带,关节囊,髋臼横韧带,和髋臼背侧边缘在所有髋关节关节镜下被发现。在所有臀部均实现了探针插入和关节内结构触诊。范围和仪器入口导致最小的关节周围肌肉创伤。未检测到坐骨神经损伤。在内窥镜插入部位的所有臀部均观察到较小的部分厚度ICI。在一个髋关节中注意到局灶性全厚度ICI。
结论：猫科动物股关节的关节镜检查允许对关节内结构进行视觉和探针评估，而没有严重的关节周围神经血管损伤的证据。医源性软骨损伤发生在所有的臀部，但病变的严重程度被认为是轻微的。
结论：Coxofemoral关节镜在猫中是可行的，可以用作微创关节评估的诊断工具。
