Knee osteoarthritis (OA) is a widespread condition that leads to joint pain, stiffness, and reduced mobility. It significantly impacts the quality of life for millions of people worldwide. Among the various treatment options available, Platelet-Rich Plasma (PRP) has emerged as a promising solution. PRP is believed to aid in the healing and regeneration of tissues due to its high concentration of growth factors and cytokines. This blog post reviews a recent peer-reviewed study that investigated the effectiveness of intra-articular injections of Autologous Conditioned Plasma (Arthrex ACP), a specific type of PRP, in treating knee OA.
The study was a prospective case series conducted at the University Medical Center Utrecht, the Netherlands, between March 2017 and October 2018. It focused on patients receiving Arthrex ACP for the first time, with a follow-up period of one year to assess the long-term effects of the treatment.

Patient Assessments:
Discussion of the Results: The study found that Arthrex ACP treatment led to statistically significant but not clinically relevant improvements in knee function and pain reduction. While these changes were measurable, they were not substantial enough to be considered meaningful improvements in the patients’ daily lives.
Why Arthrex ACP Did Not Show Significant Improvement: Several factors could contribute to the lack of significant improvement. These include the inherent variability in PRP compositions, differences in patient populations, and the placebo effect. Additionally, the study’s setting in a real-world clinical practice may introduce variability that is not present in more controlled environments.
Comparison with Previous Studies on PRP Effectiveness: Previous studies on PRP have shown mixed results. Some randomized controlled trials (RCTs) have reported significant benefits, while others have found minimal or no improvement. The inconsistencies across studies highlight the need for standardized protocols and a better understanding of patient selection criteria.
Examination of Potential Variables: The study explored various patient factors such as age, sex, BMI, Kellgren and Lawrence grade, and history of knee trauma. None of these factors were found to predict clinical outcomes, indicating that the effectiveness of Arthrex ACP may not be influenced by these variables. This suggests that other unexamined factors or a combination of factors could play a role.
Final Thoughts on the Effectiveness of Arthrex ACP for Knee OA: The findings suggest that ACP, in its current form, may not provide meaningful clinical benefits for most patients with knee OA. Healthcare providers should consider these results when discussing treatment options and set realistic expectations with patients.
Encouragement for Ongoing Research and Innovation in OA Treatment: Ongoing research and innovation are essential to improving treatment options for knee OA. Future studies should focus on optimizing PRP treatments, exploring new therapeutic approaches, and developing personalized care strategies to enhance patient outcomes.
The study reviewed in this blog post evaluated the effectiveness of Autologous Conditioned Plasma (Arthrex ACP) for treating knee osteoarthritis (OA). While Arthrex ACP led to statistically significant improvements in knee function and pain, these changes were not clinically relevant. Various patient factors, such as age, sex, BMI, and history of knee trauma, did not predict treatment outcomes.
