Findings from a study published online in The American Journal of Sports Medicine suggest that a single injection of autologous protein solution (APS) may help reduce pain for patients with knee osteoarthritis (OA). 

The authors conducted a randomized controlled trial of 46 patients with unilateral knee OA, of whom 31 were treated with APS and 15 were treated with a single saline injection. At 1-year follow-up, they found that improvement in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score was 65 percent in the APS cohort and 41 percent in the saline group. Compared with the saline cohort, the APS cohort also displayed improvement in Short Form-36 Bodily Pain and Role Emotional Health subscales as well as Clinical Global Impression of Change values. Learn more...
