Osteoarthritis Pain Models

Creative Animodel is a leading biotech company specialized in preclinical efficacy evaluation of novel therapeutics in osteoarthritis pain models. Various animal models of osteoarthritis pain are available including spontaneous models, chemistry-induced models and physically-induced models. Creative Animodel delivers customized in vivo pre-clinical test services for your osteoarthritis research.

What Is Osteoarthritis Pain?

Osteoarthritis (OA) is one of the most common forms of arthritis, causing pain and immense discomfort to the affected individual. It is characterized by the formation of bony spurs inside the joint spaces and a loss of cartilage. In a healthy joint, there is cartilage to prevent neighboring bones from making contact. While, osteoarthritis pain occurs when the cartilage is lost and boney spur formations are allowed to touch adjacent bones, causing significant inflammation and pain. Osteoarthritis has typically been classified into primary (idiopathic) and secondary osteoarthritis based on the disease etiology. Primary osteoarthritis (POA) is a naturally occurring phenomenon due to degenerative changes in the joint. Secondary osteoarthritis (SOA) is normally associated with causes and/or risk factors leading to osteoarthritis in the joint. These include trauma, congenital diseases, and other diseases or disorders of metabolism or the bone. Identifying and understanding the interplay between the various contributing mechanisms will lead to better treatment options.

An estimated 237 million of the individuals are affected with osteoarthritis in the world and the high prevalence of this disease results in a significant economic burden for the global health care industry. Although extensive substantial resources have been invested to seek therapeutic interventions for this disease, there are still no proven disease-modifying treatments for osteoarthritis. The major objects in osteoarthritis research include elucidating the pathogenesis of disease, determining methods for early diagnosis, and developing strategies for intervention and disease-modifying therapeutics.

Osteoarthritis Pain Models Provided by Creative Animodel

Animal models enable investigation of the mechanisms underlying osteoarthritis pain and help develop novel treatments. Different osteoarthritis pain models may reflect the differences in pain experiences between individual patients with osteoarthritis. There are several osteoarthritis pain models available at Creative Animodel as shown in table 1.

Model Characteristics and Pharmacology Evaluation

Osteoarthritis is a degenerative condition involving chondrocyte death and cartilage erosion affecting the entire joint structure. At Creative Animodel, we use various pain models to assess osteoarthritis pain conditions. Additionally, we offer a set of preclinical services to evaluate the efficacy of your novel therapeutics based on our osteoarthritis pain models, including but not limited to:
• Thermal Hyperalgesia and Allodynia
• Mechanical Hyperalgesia and Allodynia
• Spontaneous Pain Response
• Weight Bearing
• Gait Analysis
• Local Motor Activity
• Rotarod Test
• Measurement of Joint Swelling
• Arthritic Score
