Cranial cruciate ligament (CCL) rupture is one of the most common orthopedic conditions in dogs. The pathogenesis of CCL rupture is not fully described and remains to be elucidated fully. Several hypotheses have been proposed to explain the etiology of these changes. The objective of this study was to investigate structural changes in the CCL in relation to the tibial plateau angle (TPA) and the intercondylar notch (ICN) width in dogs. Fifty-five skeletally mature dogs were included in this study. ICN width and TPA measurements were obtained from intact CCL stifles. Samples of the CCL, caudal cruciate ligament (CaCL), and femoral head ligament (FHL) were harvested and stained for routine histological and immunohistochemical analysis. Microscopic changes in the ligaments were observed and were found to correlate with the TPA and ICN width values. The degree of structural changes within the CCL was observed to correlate with an increasing TPA and a narrowing ICN width. Changes in the CCL are likely to be caused by excessive forces acting through the ligament in stifles with a high TPA. Chondroid metaplasia of the CCL is an adaptation to abnormal mechanics within the stifle joint caused by altered bone morphology.

Background: The intercondylar notch (ICN) and the anterior cruciate ligament (ACL) are important structures in knee morphometry, with key roles in stabilizing the knee.
Aim: To determine the associations between the specific shape of the ICN (A-, W-, or U-shape) and the ACL size in patients with intact ACLs.
Methods: Magnetic resonance imaging (MRI) scans were independently analyzed by two experts: one orthopedic surgeon and one imaging physician.

Background: Both macular choroidal neovascularization (MCN) and visual changes can occur in age-related macular degeneration (AMD), central exudative chorioretinopathy (CEC), pathological myopia (PM) and idiopathic choroidal neovascularization (ICN), but whether the optical coherence tomography (OCT) manifestations of the four diseases are different and their relationships with vision are not clear. This study clarifies this problem and can guide clinicians to prevent vision changes of patients according to OCT performance.
Methods: 76 patients with MCN, included 25 AMD, 21 CEC, 18 PM and 12 ICN [refer to Chinese Ophthalmology (3rd Edition)], detected by OCT instrument, were enrolled in this study from June 2020 to June 2022.

Background Anatomic variations have been implicated as one of the intrinsic causes of injuries to the cruciate ligaments which can induce a functional deficiency to the knee. Narrow cruciate ligament widths as well as narrow femoral intercondylar notch widths can increase the risk of these ligaments rupturing. Objective To correlate the width of the femoral intercondylar notch (ICN) with anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) widths on MRI of the knee joint.
