Study Summary

The clinical efficacy of hyaluronic acid or corticosteroid injections has been reported, but effects are short lived. This has led to the development of additional injection options such as autologous derived blood products which have been documented to alleviate symptoms related to knee osteoarthritis, with recent comparative studies suggesting a greater, long-lasting effect with these blood derived products like platelet rich plasma (PRP) \[2-8\]. One clinically-developed preparation of platelet rich plasma, named autologous conditioned plasma (ACP), has randomized controlled trial data proving efficacy \[4,9\]. Clinical use of platelet rich plasma for knee arthritis typically involves a 3-injection series over 3 weeks, i.e. an injection once a week for three weeks. The main objective of this study is to determine if hyaluronic acid (HA) injected at the same time as autologous conditioned plasma (ACP), a leukocyte-poor platelet rich plasma product, will improve the performance of ACP in the treatment of symptomatic knee osteoarthritis. It is hypothesized that the injection of hyaluronic acid will improve the efficacy of ACP.

Primary Outcome

Patient reported outcome measure; The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. A sum of the scores for all three subscales gives a total score. Higher scores indicate worse pain, stiffness, and functional limitations.

Interventions
