Soundness Evaluation/Lameness

PRE’s state of the art equipment allows for PRE to specialize in lameness issues, pre-purchase examinations, and advanced regenerative medicine as a treatment option. PRE utilizes digital radiology, digital ultrasonography, diagnostic nerve blocks, joint injections, therapeutic shoeing, and regenerative medicine to correctly diagnose and treat your lameness issues.

Regenerative Medicine

PRE offers advanced regenerative medicine options for your advanced orthopedic issues. These treatments include adipose derived stem cells, platelet-rich plasma (PRP), and Interleukin-1 Receptor Antagonist Protein (IRAP). These products stimulate the body to regenerative healthy tissue where an injury has occurred. Instead of treating with anti-inflammatories such as bute or steroid injections, regenerative medicine’s goal is to replace the damage tissue with tissue that is as close to the original healthy tissue as possible.
