Clinical and ultrasonographic evaluation of the treatment of naturally occurring front limb suspensory branch injuries in sport horses with a standardized leukocyte poor platelet-rich plasma

Abstract

This study was performed to evaluate the effectiveness of ultrasound-guided injections in lesions of suspensory ligament branches of an autologous standardized leukocyte poor platelet-rich plasma. Nine sport horses with front legs suspensory ligament branch desmopathies (SLBD) were included in the study. A clinical examination and ultrasound evaluation of the affected suspensory ligament branches were carried out at the time of inclusion and on a monthly basis for 6 months after the first platelet-rich plasma (PRP) injection. Twelve branches were treated with 2–3 injections spaced by 2 weeks. Long-term follow-up at 12 months and up to 24 months for 6 horses were carried out by means of telephonic interviews with the owner. Ten out of 12 branches presented resolution of the hypoechoic lesions within three months and the treatment was associated with rapid resolution of lameness. Six of the 9 horses returned to their previous workload, 2 were in a lower level and 1 was retired. Two to three intralesional injections with RegenPRP in SLBD contributes to a rapid resolution of lameness and ultrasonographic lesions without complications. This treatment should be considered to increase the number of horses reaching their previous level of performance. Clinical results confirm that the use of a standardized autologous leukocyte poor PRP represents a convenient alternative treatment for SLB lesions.
