<p class="abstract"><strong>Background:</strong> <span lang="EN-IN">Osteoarthritis of the knee is a degenerative disorder associated with significant morbidity in the form of pain, knee stiffness and decrease in the functional capacity of the affected limb leading to a decrease in the quality of life for the patient. Various modalities of treatment are available for the management of this condition. The aim of this study was to evaluate the role of platelet rich plasma (PRP) injection in the management of early osteoarthritis of the knee and to compare the functional outcome with the studies of various authors as available in literature.</span></p><p class="abstract"><strong>Methods:</strong> <span lang="EN-IN">60 patients with Kellgrenn and Lawrence grade 1 and 2 osteoarthritis of the knee were studied from January 2014 to January 2015 and were followed up for a period of 1 year</span>.<strong></strong></p><p class="abstract"><strong>Results:</strong> <span lang="EN-IN">There were 39 males and 21 female patients in our study with the right side being more commonly affected. There was a significant decrease in the VAS score and the WOMAC score at 1, 3, 6 and 12 months follow up as compared to the pre-injection baseline scores.

Osteoarthritis of the knee (OAK) is a chronic degenerative disease and progresses with an imbalance of cytokines and macrophages in the joint. Studies regarding the use of platelet-rich plasma (PRP) as a point-of-care treatment for OAK have reported on its effect on tissue repair and suppression of inflammation but few have reported on its effect on macrophages and macrophage polarization. Based on our clinical experience with two types of PRP kits Cellaid Serum Collection Set P type kit (leukocyte-poor-PRP) and an Autologous Protein Solution kit (APS leukocyte-rich-PRP), we investigated the concentrations of humoral factors in PRPs prepared from the two kits and the effect of humoral factors on macrophage phenotypes. We found that the concentrations of cell components and humoral factors differed between PRPs purified using the two kits; APS had a higher concentration of M1 and M2 macrophage related factors. The addition of PRP supernatants to the culture media of monocyte-derived macrophages and M1 polarized macrophages revealed that PRPs suppressed M1 macrophage polarization and promoted M2 macrophage polarization. This research is the first to report the effect of PRPs purified using commercial kits on macrophage polarization.

BackgroundComparative studies of platelet-rich plasma (PRP) and hyaluronic acid show variable results. PurposeA review was conducted to understand the current role of PRP and its efficacy versus hyaluronic acid in osteoarthritis (OA) of the knee joint. MethodsOut of 170 identified studies, 14 studies involving 1575 patients with 637 males and 938 females were selected based on PRISMA flow chart guidelines and were analyzed for the study. ResultsA standard PRP regimen consisting of 2–3 intra-articular injections (IA) of 4–6 mL of leucocyte poor PRP at 1–2 weekly intervals provides a better result than HA during the first 3–6 months, and which may continue up to one year. PRP and HA may have synergistic effect; pain and swelling are the two most com-mon complications with PRP, the incidence is more with leucocyte rich PRP (LP-PRP) and intra-osseous PRP treatment.ConclusionPRP provides hope and is more effective than hyaluronic acid in pain relief and improving the quality of life in mild to moderate osteoarthritis of the knee joint. However, hype, that is effective in all, irrespective of grades of OA, mal-aligned or stiff knee, ligamentous laxity, and can avoid joint replacement is a big hindrance in establishing it as a preferred treatment in OA knee. The author follows the above-mentioned PRP regimen; and recommends to combine leucocyte poor PRP with HA for IA injections & with LP-PRP injections along with the two most common painful points (medial collateral ligament, pesanisernius) in a highly painful OA knee. PRP may not address extra-articular causes of knee pain (mal-alignment, muscle wasting, tendinosis), should be corrected for optimum outcome. Contact sports, running, exercises putting pressure on knee and NSAID should be avoided during PRP treatment. Also, more randomized controlled trials are required to further standardize the PRP preparation, administration, injection interval & proper documentation of efficacy and complications in the regenerative registry.
