Abstract (original English)

PICO question In dogs diagnosed with osteoarthritis in the hip, elbow, stifle or shoulder joint, is treatment with intra-articular allogenic mesenchymal stem cell therapy, in comparison with a placebo effect, more effective at reducing lameness and pain? Clinical bottom line Category of research question Treatment The number and type of study designs reviewed All three papers were randomised controlled trials Strength of evidence Weak Outcomes reported Intra-articular allogenic stem cell therapy is effective at reducing pain and lameness in dogs with osteoarthritis when compared to a placebo effect. Two studies indicated a statistically significant improvement in both client and veterinary outcome measurements. Client outcome measurements utilised included: the canine brief pain inventory; a measure of any changes in pain and lameness based on owners perception, and the client-specific outcome measure; and an evaluation of the impact of osteoarthritis on three client selected activities and how this changed with treatment. Veterinary outcome measurements included veterinary pain score based on manipulation of the limb, veterinary assessment of clinical outcomes and veterinary pre and post lameness examinations, all of which were subjective measures. The final study identified a statistically significant improvement in both pain and lameness based on owner assessments utilising
