Background:There has been much debate regarding the use of intra-articular injections of platelet-rich plasma (PRP) as symptomatic treatment for knee osteoarthritis. The heterogeneity of the preparation and injection protocols limits the extrapolation of data from randomized controlled trials and meta-analyses.Objectives:The objective of this expert consensus was to develop the first clinical practice recommendations for PRP injections in knee osteoarthritis.Methods:Fifteen physicians (10 rheumatologists, 4 specialists in rehabilitation and sport medicine and 1 interventional radiologist) from different countries were selected given to their expertise in the fields of PRP and osteoarthritis. Twenty-five recommendations were finally retained after several meetings using the modified Delphi method to establish clinical consensus. All experts voted their agreement or not for each recommendation using a score between 1 (totally inappropriate) and 9 (totally appropriate). Depending on the median value and extreme scores, recommendations were judged as appropriated or unappropriated with a strong or relative agreement but could also be judged as uncertain due to indecision or absence of consensus.Results:The main recommendations are listed below:- Intra-articular injections of PRP constitute an efficient treatment of early or moderate symptomatic knee osteoarthritis. Median = 8 [6-9] – Appropriate. Relative agreement.- Intra-articular injections of PRP may be useful in severe knee osteoarthritis (Kellgren-Lawrence grade IV). Median = 7 [6-7] – Appropriate. Relative agreement.- Intra-articular injections of PRP in knee osteoarthritis should be proposed as second-line therapy, after failure of non-pharmacological and pharmacological (oral and topic) symptomatic treatment. Median = 9 [5-9] – Appropriate. Relative agreement.- Intra-articular injections of PRP should not be performed in osteoarthritis flare-up with significant effusion. Median = 7 [5-9] – Appropriate. Relative agreement.- Intra-articular PRP treatment may include 1 to 3 consecutive injections. Median = 9 [7-9] – Appropriate. Strong agreement.- Leukocyte-poor PRP should be preferred for knee OA treatment. Median = 8 [5-9] – Appropriate. Relative agreement.- PRP injections should be performed under ultrasound or fluoroscopic guidance. Median = 8 [3-9] – Uncertain. No consensus.- PRP should not be mixed with injectable anesthetic or corticosteroid. Median = 9 [6-9] – Appropriate. Relative agreement.Conclusion:Twenty-five recommendations were discussed by an international multidisciplinary task force group in order to provide a basis for standardization of clinical practices and future research protocols.Disclosure of Interests:Florent Eymard Consultant of: Regenlab, Paul Ornetti: None declared, Jérémy Maillet Consultant of: Regenlab, Eric Noel Consultant of: Regenlab, Philippe Adam Consultant of: Regenlab, Virginie Legré Boyer Consultant of: Regenlab, Thierry Boyer Consultant of: Regenlab, Fadoua Allali: None declared, Vincent Grémeaux Bader: None declared, Jean-François Kaux: None declared, Karine Louati: None declared, Martin Lamontagne Consultant of: Pendopharm, Fabrice Michel: None declared, Pascal Richette: None declared, Hervé Bard Consultant of: Regenlab

Background: Although platelet-rich plasma (PRP) has potential as a regenerative treatment for knee osteoarthritis, its efficacy varies. Compositional differences among types of PRP could affect clinical outcomes, but the biological characterization of PRP is lacking. Purpose: To assess the efficacy of intra-articular PRP injection in knee osteoarthritis as compared with hyaluronic acid (HA) injection and to determine whether the clinical efficacy of PRP is associated with its biological characteristics. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 110 patients with symptomatic knee osteoarthritis received a single injection of leukocyte-rich PRP (1 commercial kit) or HA. Clinical data were assessed at baseline and at 6 weeks and 3 and 6 months after injection. The primary endpoint was an improvement in the International Knee Documentation Committee (IKDC) subjective score at 6 months, and the secondary endpoints were improvements in scores based on the Patient Global Assessment, the visual analog scale (VAS) for pain, the Western Ontario and McMaster Universities Osteoarthritis Index, and the Samsung Medical Center patellofemoral score. Cell counts and concentrations of growth factors and cytokines in the injected PRP were assessed to determine their association with clinical outcomes. Results: PRP showed significantly improvement in IKDC subjective scores at 6 months (11.5 in the PRP group vs 6.3 in the HA group; P = .029). There were no significant differences between groups in other clinical outcomes. The Patient Global Assessment score at 6 months was better in the PRP group ( P = .035). The proportion of patients who scored above the minimal clinically important difference (MCID) for VAS at 6 months was significantly higher in the PRP group ( P = .044). Within the PRP group, the concentrations of platelet-derived growth factors were high in patients with a score above the MCID for VAS at 6 months. The incidence of adverse events did not differ between the groups ( P > .05). Conclusion: PRP had better clinical efficacy than HA. High concentrations of growth factors were observed in patients who scored above the MCID for clinical outcomes in the PRP group. These findings indicate that concentration of growth factors needs to be taken into consideration for future investigations of PRP in knee osteoarthritis.

Knee osteoarthritis is a degenerative "wear and tear" disorder affecting mainly population over 50 years old. It can also present in younger people, especially after an injury or as a part of other diseases. While many therapeutic options exist for knee osteoarthritis, none of them has the potential to cure this condition. Cellular Matrix represents a combination of natural non-crosslinked hyaluronic acid (HA), thixotropic cell separation gel, and sodium citrate anticoagulant solution. A combination of Cellular Matrix with autologous platelet-rich plasma (A-PRP) is a novel therapeutic approach to the management of knee osteoarthritis. It is assumed that the active components HA and PRP have a synergistic effect contributing to a better therapeutic outcome in patients with knee osteoarthritis. Physiotherapy could provide an additional benefit. This is a retrospective pilot study assessing the potential benefit of Cellular Matrix and A-PRP combined with physiotherapy in the management of chronic knee osteoarthritis. Twenty-five patients were enrolled in the study and injected with three doses of Cellular Matrix combined with A-PRP with a time span of 2 weeks between each injection. All patients received standardized physiotherapy. The results showed that 68% of patients achieved more than 50% improvement in pain, stiffness, and function of the knee joints. There were no adverse reactions. This retrospective pilot study confirmed the positive effect of PRP and HA combination in the management of mild and moderate knee osteoarthritis. These preliminary results need to be verified in randomized control trials.

Abstract Knee osteoarthritis is a degenerative joint disease characterized by cartilage degeneration and hypertrophic lesions of the epiphyseal bone. It is a disabling condition that causes difficulties of locomotion and severe complications in case of inappropriate treatment. There is growing evidence proving the beneficial effects of using platelet-rich plasma (PRP) in the treatment of knee osteoarthritis. The aim of the present paper is to review the recent scientific literature on the treatment of knee osteoarthritis with platelet-rich plasma presenting the current opinion on this subject. Methods: We analys several studies about PRP who were identified using online databases: EBSCO, ScienceDirect, Scopus and PubMed. Results: After the primary analysis we selected a total of 23 relevant studies. The analysis focused on different PRP administration techniques and methods used in knee osteoarthritis. Conclusions: PRP is most widely used in incipient and moderate symptomatic knee osteoarthritis. Most studies show a significant decrease in pain and significant improvement in joint functionality. These results were mostly obtained after a short follow-up period (6 months-1 year) and also this treatment has a small number of side effects.

The Mean

Osteoarthritis (OA) of the knee is a degenerative, non-inflammatory joint condition marked by articular cartilage disintegration and the growth of new bone (osteophytes) at the joint surfaces and borders. It impairs one's ability to function and makes one disabled. It is the most common rheumatic disease. Because the Knee is a weight-bearing joint and a crutch joint, it is the most usually afflicted joint by Osteoarthritis.A Correlational study was conducted to find out the correlation between Knee Society Score (KSS) and Oxford Knee Score (OKS) on 142 Osteoarthritis Knees. Purposive sampling was used to collect data from the Orthopaedics OPD at AIIMS Jodhpur from October to December 2018.On evaluation, the mean age of the patients was 60.19±1.01. Bilateral Knee Osteoarthritis affected about 42% of the patients. Approximately half of the patients were obese. Only 34% of patients had compliance in physiotherapy. Analgesics and massage treatment are used by about 76% of the patients to relieve knee pain. In the Knee Society Score, the majority of the patients (82.4%) had a bad knee condition, with a mean score of 49.07±1.06. In OKS, about half of the patients (46.5%) had Moderate to Severe Knee Osteoarthritis, with a mean score of 22.69±7.09. The correlation coefficient between the Knee Society Score and the Oxford Knee Score is 0.660. As a consequence of the analysis, both scales have almost the same outcome, indicating that they are moderately associated. The Knee Society Score is highly associated with occupation and physiotherapy, whereas the Oxford Knee Score is significantly related to the patients' age alone. According to the study, there is a moderate correlation between the Knee Society Score (KSS) and the Oxford Knee Score (OKS). These scores should be included during the diagnosis of Knee Osteoarthritis for improved patient care.
