Objectives: Osteoarthritis (OA) of the knee is a debilitating disease whose prevalence has increased across the world with aging population. Platelet-Rich Plasma (PRP) and Hyaluronic Acid (HA) injections appear to be two of the main strategies for conservative treatment of early knee OA. The effectiveness of both treatments, however, is still under debate because contrasting results have been described in the current literature. Some pre-clinical studies evaluated the association of PRP and HA with encouraging results, highlighting the possibility of a synergistic effect between the two compounds and suggesting a possible use through combined intra-articular injections. The aim of this prospective randomized controlled double-blind clinical trial is to evaluate the efficacy of intra-articular injections of PRP and HA for the treatment of early stages of knee degenerative joint disease in improving joint function and reducing pain, compared to the intra-articular injections of PRP and HA alone. Methods: Patients with knee early OA were prospectively enrolled and then double-blinded randomly divided into three groups of fifty-eight subjects each: HA alone, PRP alone and PRP+HA group. Patients received three intra-articular injections with two-week interval period among each dose. Patients clinical outcome was evaluated through five questionnaires [The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Tegner Activity, Visual Analogue Scale (VAS), Knee injury and Osteoarthritis Outcome Score (KOOS), and International Knee Documentation Committee (IKDC) Subjective Knee Form] before the treatment (T0) and after 3, 6 and 12 months from the first injection. Patients’use of paracetamol and supplementary analgesia for knee pain during the study was collected. Results: One hundred and seventy-four patients were enrolled in this study (age, 30-80 years; 108 females and 66 males) and 162 completed the 12-month follow-up. All patients showed significant clinical improvement after treatment. The analysis of covariance (ANCOVA) did not show statistically significant differences among the three groups for all the variables analysed at 6 and 12 months of follow-up (p>0.05).No significant differences were found in terms of adverse events (p=0.49) among the three groups of patients (p=0.92).The demand for paracetamol and supplementary analgesics was generally low and there were no significant differences among the groups (p=0.23 and p=0.56, respectively). Conclusions: Injections treatments for early knee OA are an important conservative therapeutic strategy. To date, the current literature presents many contrasting studies about the effectiveness of PRP or HA, but only a few consider the combined use of PRP and HA as attractive therapeutic option. Our study has not shown any significant difference in clinical and functional outcomes among the three experimental groups, suggesting a substantial equivalence of these three treatments. Thus, cost-effectiveness is in favor of HA injections in the conservative treatment of early OA.

Objective. The purpose of this meta-analysis was to determine whether platelet-rich plasma (PRP) was better than hyaluronic acid (HA) for the treatment of knee osteoarthritis (OA) in overweight or obese patients. Design. Two reviewers independently used the keywords combined with free words to search English-based electronic databases according to Cochrane Collaboration guidelines, such as PubMed, Embase, ScienceDirect, and Cochrane library. The pooled data were analyzed using RevMan 5.3. Results. Ten randomized controlled trials (RCTs) with 1096 patients were included. During the first two months of follow-up, there was no significant difference between the two groups. At the 3rd, 6th, and 12th months of follow-up, the pooled analysis showed that PRP was better than HA for the treatment of knee OA in overweight or obese patients. There were significant differences between the two groups at Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score (3 months: MD = −1.35, [95% CI: −2.19 to −0.50], P=0.002, I2 = 0%; 6 months: MD = −7.62, [95% CI: −13.51 to −1.72], P=0.01, I2 = 88%; 12 months: MD = −12.11, [95% CI: −20.21 to −4.01], P=0.003, I2 = 94%). Conclusions. For overweight or obese patients with knee OA, intra-articular injection of PRP in a short time was not necessarily superior to HA, but long-term use was better than HA in pain and functional relief.

Abstract We investigate whether platelet-rich plasma (PRP) injections can improve symptoms and function in patients with mild to moderate osteoarthritis (OA). Data were prospectively collected and retrospectively reviewed for all patients receiving PRP intra-articular hip injections between February 2017 and June 2017. The inclusion criteria were patients with a well-preserved joint space (Tönnis 0 or 1) whose magnetic resonance imaging (MRI) findings demonstrated degenerative joint disease or a Tönnis grade of 2. The patient-reported outcomes (PROs) used were the modified Harris Hip Score (mHHS), Hip Outcome Score-Activities of Daily Living Subscale (HOS-ADL), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), International Hip Outcome TOOL (iHOT-12), Single Assessment Numeric Evaluation (SANE) and Mental and Physical aspects of the Veteran RAND 12 Item Health Survey (VR-12M and VR-12P). The visual analog scale (VAS) was utilized to indicate pain. Nine patients (11 hips) were eligible for inclusion. All PROs and VAS improved from pre- to post-injection. These improvements were present at the 3-month follow-up visit and stable until the 12-month follow-up. There was statistically significant improvement for mHHS (P < 0.001), HOS-ADL (P = 0.006), iHOT-12 (P = 0.003) and VR-12M (P = 0.005) at 12 months post-injection. Similarly, VAS improved from 4.1 to 2.3, although the change was not statistically significant. PRP injections significantly improved PROs in all measured scales at time points up to a year after intervention, except for VR-12P and HOS-SSS. In conclusion, patients with early OA of the hip had significant improvement of patient-reported functional outcomes up to 12 months after PRP intra-articular injections.

Abstract Background This study aimed to evaluate the clinical efficacy of platelet-rich plasma (PRP) injection compared with hyaluronic acid (HA) injection for patients undergoing knee osteoarthritis. Methods We systematically searched electronic databases including PubMed, Embase, Web of Science, and the Cochrane Library on January 23, 2020 to identify relevant studies issued in English languages. The outcomes evaluating the efficacy of knee osteoarthritis (KOA) treatment were Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores (WOMAC pain, function, stiffness, and total scores) at 1, 3, 6, and 12 months; International Knee Documentation Committee (IKDC) scores, Lequesne Index score, Visual Analog Scale (VAS) scores, EQ-VAS scores, and KOOS scores. The pooled data were analyzed by Stata 12.0. Results A total of 20 RCTs were enrolled in the present meta-analysis. The pooled results demonstrated that platelet-rich plasma (PRP) injection reduced pain more effectively than hyaluronic acid (HA) injection at 6-month and 12-month follow-up evaluated by WOMAC pain scores and VAS scores. EQ-VAS in the patients treated with PRP injection was lower than that in patients with HA injection at 12 months. Moreover, the patients with PRP injection had a better function recovery than those with HA injection at 1-month, 3-month, 6-month, and 12-month follow-up, as evaluated by WOMAC function scores. WOMAC total scores showed significant difference at 6-month and 12-month follow-up. The IKDC scores indicated PRP injection was significantly more effective than HA injection at 3 months and 6 months. However, the Lequesne Index scores, KOOS scores, and adverse events did not show any significant difference between groups. Conclusion Intra-articular PRP injection appeared to be more efficacious than HA injection for the treatment of KOA in terms of short-term functional recovery. Moreover, PRP injection was superior to HA injection in terms of long-term pain relief and function improvement. In addition, PRP injection did not increase the risk of adverse events compared to HA injection.

Retrospective Comparative Study

The development of hallux interphalangeal joint (IPJ) arthritis after an arthrodesis of the first metatarsophalangeal joint has been established in the literature. However, the significance has not been well reported. A retrospective, radiographic review of patients who had undergone a first metatarsophalangeal joint arthrodesis was performed. The Coughlin classification for degree of arthritic degeneration, hallux abductus angle, and hallux interphalangeus angle were measured in 107 radiographs of 103 patients preoperatively and postoperatively. Postoperative angles were measured immediately following surgery at approximately 6 weeks, 3 months, 6 months, 12 months, and 24 months. We found that the hallux abductus angle had decreased in the patients postoperatively; however, the hallux abductus interphalangeus angle increased on average after first metatarsophalangeal fusion. The majority of patients started with a Coughlin classification I of the hallux IPJ, which remained unchanged over the postoperative period, with no statistically significant difference in IPJ degeneration in the patients with or without fusion of the first metatarsophalangeal joint. In addition, no patients had a symptomatic hallux IPJ postoperatively within our limited study period. Further prospective studies would be beneficial with longer follow-up times to assess IPJ degeneration following first metatarsophalangeal joint fusions. Levels of Evidence: Level III: Retrospective, comparative study

Background: Platelet-rich plasma (PRP) injections have been proposed as a biologic option to provide symptomatic relief and delay surgery in patients with degenerative joint disease of osteoarthritis (OA). The efficacy of autologous PRP on symptomatic degenerative meniscal lesions (DMLs) has never been investigated. Hypothesis: We hypothesized that patients with symptomatic DMLs without OA undergoing autologous PRP injections experience a significant clinical improvement at 12 months. Study Design: Prospective case series. Level of Evidence: Level 4. Methods: A total of 69 patients with symptomatic DMLs without radiographic evidence of knee OA (Kellgren-Lawrence radiographic grading scale 0-1) received 4 autologous PRP injections once a week. Patients were prospectively evaluated before the injection and then at 1, 3, 6, and 12 months. Evaluation was based on Lysholm knee scoring scale (primary outcome), Western Ontario and McMaster Universities Arthritis Index (WOMAC), Tegner activity scale, and visual analogue scale scores. Results: Patients treated with PRP injections demonstrated an improving knee function and symptoms over the duration of the study. A significant improvement from baseline to 12 months was observed in all the outcome measures, and no patients experienced failure or required surgery during the follow-up. Patients younger than 50 years reported lower subjective level of pain and higher Tegner activity scale at baseline and had significantly better Lysholm knee scoring scale ( P = 0.03) and WOMAC ( P = 0.03) scores at 6 months, as well as better range of motion at 3, 6, and 12 months ( P < 0.001). Thirty-three (47.8%) patients were very satisfied, 26 (37.7%) satisfied, 8 (11.6%) partially satisfied, and 2 (2.9 %) not satisfied, with 62 (89.8%) patients willing to repeat the same treatment. No patient was lost to follow-up and no patient experienced adverse reaction, infection, failure, recurrence or underwent further surgery. Conclusion: PRP injections provide short-term benefits in symptomatic DMLs. Although promising results were evident at 12 months, this is a preliminary study and no definitive recommendation can be made based, for example, on longer follow-up. Clinical Relevance: This research supports the use of autologous PRP injections for symptomatic DMLs.

Due to its easy preparation and that it is well tolerated, the use of autologous platelet-rich plasma (PRP) has become increasingly popular in regenerative medicine. However, there are still no clear guidelines on how it should be classified or whether the individual canine patient’s clinical status can influence its quality. Objective: This study aims to show if the weight, age, sex, neutered status or breed of canine patients have any correlation with the composition of PRP. Design: A blinded count of the platelets and white blood cells (WBC) was performed from 111 samples from 92 client owned dogs undergoing treatment for degenerative joint disease (DJD). The results were analysed using Pearson correlation test, ANOVA test or Student T-test. Results: There is a positive correlation between the number of platelets and WBC in canine patients of different breeds, but there was no significant difference on the platelet number and WBC number among the different breeds. The weight of the patient is also directly correlated to the platelet number (p = 0.003) but not WBC number. WBC number was negatively correlated to the weight of the patient. The sex and age of the patient did not affect platelets and WBC number, although WBC number is increased in non-neutered male population (p = 0.003). However, it would be interesting to investigate whether the growth factors released from the platelet granules are affected by patient variables in a canine population. Conclusions: Our results show that it is possible to obtain good quality autologous PRP, irrespective of age, sex, neutered status or weight of the patient, for PRP regenerative therapy.

Knee Oa

Osteoarthritis (OA) is a progressive joint disease associated with both mechanical and biologic abnormalities of the articular cartilage and subchondral bone. In normal cartilage, a delicate balance exists between matrix synthesis and degradation; in OA, however, cartilage degradation exceeds synthesis. Treatment modalities include nonpharmacological, pharmacological, and surgical approaches. Intrarticular platelet rich plasma (PRP) has emerged as promising treatment for early stages of knee OA. PRP is an autologous blood product defined as a volume of plasma that has a supraphysiologic platelet count. PRP can accelerate the physiological recovery process, relieve pain, and contains anti-inflammatory and anti-bacterial activity. Although the mechanisms for these complex interactions are not completely understood, they are attributed to the more than 30 bioactive proteins contained in the alpha granules of platelets including growth factors and proteins, such as fibrin, fibronectin, vitronectin and thrombospondin. Several studies now have demonstrated that intraarticular PRP injections are safe and effective treatment to reduce pain and improve quality of life through increased function in knee OA. The available literature suggests that PRP is a better option than hyaluronic acid for many knee OA patients. We identified 12 comparative studies that demonstrated superiority of PRP as compared to hyaluronic acid for knee OA. Considering what is known about the deleterious effects of local anesthetic and corticosteroids on soft tissue health, it may be time for a shift in the knee OA treatment algorithm to favor early intervention for regenerative therapies including platelet rich plasma.

Abstract Background Although PRP is one of the options in the management of knee OA, its effectiveness and wide application is still controversial. Therefore, we conducted the present systematic review and meta-analysis to compare the safety and effectiveness of PRP versus HA injection for knee OA. Objective The purpose of this study is to compare between the efficacy of intra-articular injections of Platelet-Rich Plasma versus Hyaluronic Acid in treatment of knee osteoarthritis. Methods We performed this systematic review and meta-analysis in accordance to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and Meta-analysis Of Observational Studies in Epidemiology (MOOSE) statement. PRISMA and MOOSE are reporting checklists for Authors, Editors, and Reviewers of Meta-analyses of interventional and observational studies. According to International committee of medical journal association (ICJME), reviewers must report their findings according to each of the items listed in those checklists. Results The overall effect favoured PRP over HA for WOMAC function score, WOMAC pain score, WOMAC stiffness score, and WOMAC total score; mostly 6 and 12 months after treatment. According VAS score, we found that the overall effect favoured PRP over HA at 12 months only. In contrary, the overall effect did not favour PRP over HA for VAS score at 3 and 6 months. PRP is superior to HA for IKDC scores at 6 and 12 months with similar results at 3 months. Conclusion Intra-articular PRP injection is more effective in terms of pain relief and function improvement at short-term follow-up in the treatment of knee OA than HA, and there is no significant difference in the risk of adverse events between PRP and HA. A randomized controlled trial with larger group sizes is necessary to find the predictors of the response to PRP and HA intra-articular injection.

The major famous degenerative joint disease is osteoarthritis (OA), which leads to disability, reduced motion, pain, swelling, and crepitus. Thus, this research aimed to determine the statuses of oxidative stress (OS) and antioxidants in blood patients with primary OA and to compare serum levels of some inflammatory markers between control and knee OA patients groups. In this case-control study, 126 knee OA patients and 49 control individuals were taken, who visited the Center of Rheumatoid in Duhok city, Kurdistan region of Iraq. For the participant’s information, a study questionnaire was employed. Serum total bilirubin (TBIL), uric acid (UA), catalase, peroxynitrite (PN), malondialdehyde (MDA), and ceruloplasmin (CP) were evaluated. Some inflammatory markers were measured, including erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Also, body mass index (BMI) was measured. In the present study, the % of the control group was 28% and patients groups were 29.71, 28, and 14.29% for mild, moderate, and severe cases, respectively. The mean values of MDA and CP showed significant differences between knee OA and control groups. On the other hand, the mean values of catalase, PN, UA, and TBIL showed no significant differences among control and knee OA groups. A significant difference was found among control and knee OA groups for ESR, but CRP was non-significant. In the current study, elevated levels of lipid-peroxidation and CP in patients with knee OA were observed. OS may be involved in OA.

Background: Platelet Rich Plasma (PRP) is increasingly applied in clinical practice to treat knee degenerative pathology. Both PRP and hyaluronic acid (HA) have been extensively used to improve lubrication, modulate inflammation and modify the catabolic micro-environment of the joint. Objective: This study was aimed to evaluate the potential synergistic effects of PRP in combination with hyaluronic acid in primary knee osteoarthritis. Methodology: This randomized control trial was carried out on adult patients with primary knee osteoarthritis who attended the Pain Clinic of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh, during the period of September 2015 to August 2017. The patients were randomly assigned to one of the two groups designated as group P (control group) who were only treated with PRP and group PH (experimental group) who were treated with the combination of PRP and hyaluronic acid. After providing the allocated treatment, all patients were undergone follow-up examination at 1st week, 1st month and 3rd month for pain improvement by VAS scale and for functional improvement by International Knee Documentation Committee (IKDC) score. Results: A total number of 34 patients were recruited for this study. Visual analogue score 1st month (5.85±0.83) and 3rd month (3.01±0.12) follow up showed statistically significant difference among two group (p=0.001). Inter group comparison showed that, mean VAS score of group PH (3.01±0.12) decreased more than Group P (4.01±1.01). In case of functional improvement, group PH also showed statistically better improvement during 1st month (45.76±3.25) and 3rd month (62.06±5.37) follow up than Group P. Conclusion: In conclusion articular platelet rich plasma in combination with hyaluronic acid provide better pain relief and improvement of functional status than PRP therapy alone in primary knee osteoarthritis.
