Evaluation of Patella Anatomy for Total Knee Arthroplasty Approaches.
Cureus
May 2024
Anatomy, Bilkent City Hospital, Ankara, TUR.
Article Synopsis
- The patella, or kneecap, is an important sesamoid bone that helps form the patellofemoral component of the knee joint, which can be surgically rebuilt using total knee arthroplasty (TKA) when damaged by various arthritis types.
- This study analyzes the morphometry of 168 human patellae, examining various parameters and applying the Wiberg classification to categorize the samples.
- Significant differences were found in patellar measurements between the left and right sides, as well as among different Wiberg types, highlighting the importance of understanding patellar morphology for surgical procedures and medical evaluations.
Non-invasive electroarthrography measures cartilage in live horses and correlates to direct measurements of cartilage streaming potentials in weight bearing regions of equine metacarpophalangeal joints.
Osteoarthritis Cartilage
October 2024
Comparative Orthopaedic Research Laboratory, Department of Clinical Studies, University of Guelph, Guelph, Ontario, Canada.
Objective: To perform non-invasive Electroarthrography (EAG) on live horses and establish relationships between EAG and direct measurements of cartilage streaming potentials in weight bearing areas of the equine metacarpophalangeal joint.
Design: EAG was performed bilaterally on the metacarpophalangeal joints of live horses (n = 3). Separate experiments used metacarpophalangeal joint explants (n = 11) to measure EAG obtained during simulated loading followed by direct measurements of cartilage streaming potentials on joint surfaces using the Arthro-BST probe.
Ultrasonography, computed tomography and magnetic resonance imaging of the dromedary camel distal limbs.
BMC Vet Res
January 2024
Department of Surgery, Anesthesiology and Radiology, Faculty of Veterinary Medicine, Beni-Suef University, 62511, Beni-Suef, Egypt.
Background: Lameness associated with the distal limb region in dromedary camels is quiet prevalent. The diagnosis of lameness relies on a comprehensive orthopedic examination conjugated with an appropriate imaging modality to achieve a decisive diagnosis. Using of modern imaging tools provoked a significant breakthrough in the diagnosis of lameness.

November 2021
From the Equine Orthopaedic Research Center and Translational Medicine Institute, Department of Clinical Sciences, and Department of Environmental and Radiological Health Sciences, College of Veterinary Medicine & Biomedical Sciences, Colorado State University, Fort Collins, CO 80523.
Objective: To describe the technique and assess the diagnostic potential and limitations of tomosynthesis for imaging of the metacarpophalangeal joint (MCPJ) of equine cadavers; compare the tomosynthesis appearance of pathological lesions with their conventional radiographic, CT, and MRI appearances; and evaluate all imaging findings with gross lesions of a given MCPJ.
Sample: Distal portions of 4 forelimbs from 4 equine cadavers.
Procedures: The MCPJs underwent radiography, tomosynthesis (with a purpose-built benchtop unit), CT, and MRI; thereafter, MCPJs were disarticulated and evaluated for the presence of gross lesions.
Treatment of Fabella syndrome with arthroscopic fabellectomy: a case series and literature review.
BMC Musculoskelet Disord
August 2021
Orthopedic Department, Chi-Mei Medical Center, No.901, Zhonghua Rd., Yongkang Dist., Tainan City, Taiwan (Republic of China).
Background: The fabella is a sesamoid bone in the posterolateral capsule of the human knee joint. In quadrupedal mammals, the fabella is believed to have a role similar to the patella in redirecting extension forces of the knee joint from one point to another. In bipeds, the fabella is not touching the back of the bent knee, and therefore the role in redirecting forces declines.
