Trial Summary

What is the purpose of this trial?

To demonstrate the efficacy of the combined use of platelet-rich plasma (PRP) with lipoaspirate and/or bone marrow aspirate in osteoarthritis of major joints, and to compare the outcomes achieved using three combinations: PRP plus lipoaspirate, PRP plus bone marrow aspirate, and PRP plus both lipoaspirate and bone marrow aspirate.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you must be able to pause antiplatelet therapy before the procedure.

What data supports the effectiveness of the treatment PRP + Cell Therapy for Osteoarthritis?

Research shows that both platelet-rich plasma (PRP) and bone marrow aspirate concentrate (BMAC) can improve pain and function in knee osteoarthritis, suggesting that combining these therapies may be beneficial. ^{1 2 3 4 5}

Is PRP + Cell Therapy safe for humans?

Research on PRP and bone marrow aspirate concentrate (BMAC) therapies, which are used for conditions like knee osteoarthritis, suggests they are generally safe as they are derived from the patient's own tissues, reducing the risk of rejection or severe side effects. ^{1 6 7 8 9}

How is the PRP + Cell Therapy treatment for osteoarthritis different from other treatments?

PRP + Cell Therapy is unique because it uses the patient's own cells and blood components, like platelet-rich plasma (PRP) and bone marrow aspirate concentrate (BMAC), to potentially repair cartilage and reduce pain, unlike traditional drugs or surgery. ^{1 2 10 11 12}

Findings from Research

A randomized controlled trial involving 90 participants with knee osteoarthritis found that both autologous platelet-rich plasma (PRP) and bone marrow aspirate concentrate (BMC) injections significantly improved pain and function for up to 12 months, with no significant differences in outcomes between the two treatments.

While PRP has a strong clinical evidence base for treating knee osteoarthritis, BMC showed similar effectiveness in this study, indicating that both treatments can be viable options, but neither was superior to the other.

Intraarticular injections of autologous platelet-rich plasma (PRP) and bone marrow concentrate (BMC) significantly reduced inflammatory cytokines and delayed cartilage degeneration in a goat model of osteoarthritis, indicating their therapeutic efficacy.

The BMC treatment provided greater cartilage protection and less loss of extracellular matrix compared to PRP, suggesting that BMC may be a more effective option for treating osteoarthritis.

A systematic review of 27 Level I studies involving 2,396 patients found that platelet-rich plasma (PRP) and bone marrow aspirate concentrate (BMAC) injections significantly improved knee osteoarthritis symptoms compared to hyaluronic acid (HA) injections, as measured by patient-reported outcome scores.

There were no significant differences in outcomes between PRP and BMAC, suggesting both treatments are equally effective for improving knee OA symptoms.

In a case study of 3 females with knee osteoarthritis, the combination of a single bone marrow aspiration concentrate (BMAC) injection followed by a platelet-rich plasma (PRP) injection led to improvements in pain and functionality scores for all patients.

These results suggest that using BMAC and PRP together may enhance pain relief and functional status, potentially improving the quality of life for individuals suffering from knee osteoarthritis.

Bone marrow aspirate concentrate (BMAC) and platelet-rich plasma (PRP) both significantly enhance initial bone regeneration when combined with β-tricalcium phosphate (β-TCP) in an immunodeficient mouse model, with new bone formation observed at 7.6% and 7.2% respectively, compared to only 2.7% in the control group.

The study found that while both BMAC and PRP increased the number of bone cells and showed similar efficacy in promoting bone growth, the differences in effectiveness between the two treatments were not statistically significant.

In a study involving 21 male rabbits with knee lesions, both platelet-rich plasma (PRP) and bone marrow aspirate concentrate (BMAC) treatments showed improved articular surface remodeling compared to a control group, indicating their potential effectiveness in treating knee injuries.

The use of regenerative therapies like PRP and BMAC after surgery can enhance joint outcomes and reduce degeneration, suggesting they should be considered as valuable adjunct treatments in orthopedic practice.

Autologous biological preparations, known as orthobiologics, are increasingly used in orthopedic procedures and surgeries, utilizing the patient's own tissues to create treatments like platelet-rich plasma (PRP) and bone marrow concentrate (BMC).

The article highlights the physiological variability in the preparation of BMC and adipose tissue concentrate (ATC), which can affect the delivery of mesenchymal stem cells and their effectiveness in supporting tissue repair.

Autologous platelet-rich plasma (PRP) shows promise in reducing pain from osteoarthritis and may aid in cartilage repair, highlighting its potential therapeutic benefits.

PRP is derived from the patient's own blood and contains a variety of growth factors, but the commercial versions available can vary significantly in composition, which may affect their efficacy.

The systematic review analyzed 16 articles on injectable ortho-biological treatments for severe knee osteoarthritis (OA), including platelet-rich plasma (PRP) and mesenchymal cells, but found no consistent beneficial effects across studies.

Due to the variability in treatment protocols, follow-up periods, and small sample sizes, the study concluded that there is insufficient evidence to recommend routine use of these injectable treatments for severe knee OA, highlighting the need for larger, randomized clinical trials.

PTP-001, a novel placental tissue particulate, contains significantly higher levels of key growth factors compared to both leukocyte-rich and leukocyte-poor platelet-rich plasma (PRP), suggesting a potentially more effective treatment for knee osteoarthritis.

Both PTP-001 and PRP can reduce inflammation in cell cultures, but PTP-001 shows more consistent results and greater efficacy in reducing harmful gene expressions related to cartilage degradation, indicating its superior therapeutic potential.
