Aims. Intra-articular (IA) injection may be used when treating hip osteoarthritis (OA). Common injections include steroids, hyaluronic acid (HA), local anaesthetic, and platelet-rich plasma (PRP). Network meta-analysis allows for comparisons between two or more treatment groups and uses direct and indirect comparisons between interventions. This network meta-analysis aims to compare the efficacy of various IA injections used in the management of hip OA with a follow-up of up to six months. Methods. This systematic review and network meta-analysis used a Bayesian random-effects model to evaluate the direct and indirect comparisons among all treatment options. PubMed, Web of Science, Clinicaltrial.gov, EMBASE, MEDLINE, and the Cochrane Library were searched from inception to February 2023. Randomized controlled trials (RCTs) which evaluate the efficacy of HA, PRP, local anaesthetic, steroid, steroid+anaesthetic, HA+PRP, and physiological saline injection as a placebo, for patients with hip OA were included. Results. In this meta-analysis of 16 RCTs with a total of 1,735 participants, steroid injection was found to be significantly more effective than
Aims. To determine whether platelet-rich plasma (PRP) injection improves outcomes two years after acute Achilles tendon rupture. Methods. A randomized multicentre two-arm parallel-group, participant- and assessor-blinded superiority trial was undertaken. Recruitment commenced on 28 July 2015 and two-year follow-up was completed in 21 October 2019. Participants were 230 adults aged 18 years and over, with acute Achilles tendon rupture managed with non-surgical treatment from 19 UK hospitals. Exclusions were insertion or musculotendinous junction injuries, major leg injury or deformity, diabetes, platelet or haematological disorder, medication with systemic corticosteroids, anticoagulation therapy treatment, and other contraindicating conditions. Participants were randomized via a central online system 1:1 to PRP or
A Morton's neuroma is a painful forefoot disorder characterised by plantar pain and toe paraesthesia. Many treatments have been tried including modification of shoe wear, injections and surgery. The results from different treatment modalities are extremely variable in the scientific literature. We reviewed 79 patients who presented with an ultrasound proven Morton's Neuromata at an average of 60 months following treatment in a patient blind randomised trial. 35 had surgery with resection of the Morton's Neuromata. We compared the results of the patients who had had a steroid injection and surgery, a steroid injection alone, a
Aim: To assess the efficiency of pre-emptive analgesia in a clinical setting as opposed to closely controlled animal models, looking at postoperative pain scores, total analgesia requirement and amount of general anaesthetic agent required during surgery. Methods and Results. Subject to exclusions, 40 patients undergoing day-case arthroscopy of the knee (mean age 44 years, ASA grade 1–2) were randomized into two treatment groups. All patients had general anaesthesia. The trial group received an injection of 15mI 0.5% Bupivicaine / 1/200,000 adrenaline pre-emptively. After surgery a
Objective: In the absence of dependable and reproducible non-surgical treatment alternatives for osteoarthritis (OA), new approaches are needed. A new therapy, based on the intra-articular injection of autologous conditioned serum (ACS), is used in several European countries. ACS is generated by incubating venous blood with medical grade glass beads. Peripheral blood leukocytes produce elevated amounts of endogenous anti-inflammatory cytokines such as interleukin-1 receptor antagonist (IL-1Ra) that are recovered in the serum(. 1. ). In the present study, the clinical efficacy and safety of intra-articular injections of ACS were compared to intra-articular hyaluronan (HA), and placebo (saline) in patients with confirmed knee OA. Study Methods: In a prospective, randomized, patient- and observer-blind, placebo-controlled trial with three parallel groups, 399 patient knees with OA were included in an intention to treat (ITT-) analysis. Efficacy was assessed by patient-administered outcome instruments (WOMAC, VAS, SF-8, GPA) after 7, 13 and 26 weeks. The frequency and severity of adverse events were used as safety parameters. Results: In all treatment groups, intra-articular injections produced a significant reduction in WOMAC-scores and weight-bearing pain (VAS), as well as improvement in health-related quality of life. However, responses to ACS were far stronger. The superiority of ACS and either HA or placebo was statistically significant for all outcome measures and all time points. The mean improvement for patients treated with HA and placebo was half that in the ACS-group (p<
0.001). No significant differences between HA treatment and
Introduction: Analgesia from controlled injections of local anaesthetic into the lumbar zygapohysial joint (z-joint) has been accepted as the standard for diagnosis of z-joint pain. Little is known about the placebo-response rate. Aim of this pilot study is to validate the fluoroscopically controlled z-joint-injection (ZJI) as an instrument for diagnosis of degenerative symptomatic z-joint disease. Material and Methods: Due to degenerative lumbar spine syndrome 50 z-joints (L5/5: 27; L5/S1 23) were injected three times in a single blinded trial bilaterally. According to a randomisation protocol, using the oblique needle technique the ZJI were done with an local anaesthetic (LA: 1.5 ml 0.5% Scandicain), a saline placebo (sodium: 1.5ml 0.9% NaCl) and with no agent (sicca punction). The pain level before and after the injections (30 min, 1 and 2–3 hours) was documented by the patient on a 10pts.-VAS. Improvement in the pain level after an FJI is defined as responder. A responder reacts false positive if the degree of effectiveness of the placebo-FJI is the same or better than the response to LA. A patient reacts false negative if the pain diminution after LA application is lower than after placebo. Results: Preliminary results regarding the reactions 30 min after injection are presented. 26% were non-responder and 52.9% LA-responder. The sicca response rate was 38%, for sodium it was 46%. Reaction after sicca-FJI was false positive in 24%, after sodium-FJI in 32% of cases. 38% reacted false negative to LA-injection. The order of the agent application didn’t have significant influence on the responder rates and also not on the extent of contradictory effects. Conclusions: Despite numerous examinations none could sufficiently evaluate accurate reliable predictors for positive ZJI-responders till now. This is confirmed by our high LA-non-responder-rate of 48.1%. However, only a
The aim of the HIPGEN consortium is to develop the first cell therapy product for hip fracture patients using PLacental-eXpanded (PLX-PAD) stromal cells. HIPGEN is a multicentre, multinational, randomized, double-blind, placebo-controlled trial. A total of 240 patients aged 60 to 90 years with low-energy femoral neck fractures (FNF) will be allocated to two arms and receive an intramuscular injection of either 150 × 106 PLX-PAD cells or placebo into the medial gluteal muscle after direct lateral implantation of total or hemi hip arthroplasty. Patients will be followed for two years. The primary endpoint is the Short Physical Performance Battery (SPPB) at week 26. Secondary and exploratory endpoints include morphological parameters (lean body mass), functional parameters (abduction and handgrip strength, symmetry in gait, weightbearing), all-cause mortality rate and patient-reported outcome measures (Lower Limb Measure, EuroQol five-dimension questionnaire). Immunological biomarker and in vitro studies will be performed to analyze the PLX-PAD mechanism of action. A sample size of 240 subjects was calculated providing 88% power for the detection of a 1 SPPB point treatment effect for a two-sided test with an α level of 5%.Aims

To estimate the potential cost-effectiveness of adalimumab compared with standard care alone for the treatment of early-stage Dupuytren’s disease (DD) and the value of further research from an NHS perspective. We used data from the Repurposing anti-TNF for Dupuytren’s disease (RIDD) randomized controlled trial of intranodular adalimumab injections in patients with early-stage progressive DD. RIDD found that intranodular adalimumab injections reduced nodule hardness and size in patients with early-stage DD, indicating the potential to control disease progression. A within-trial cost-utility analysis compared four adalimumab injections with no further treatment against standard care alone, taking a 12-month time horizon and using prospective data on EuroQol five-dimension five-level questionnaire (EQ-5D-5L) and resource use from the RIDD trial. We also developed a patient-level simulation model similar to a Markov model to extrapolate trial outcomes over a lifetime using data from the RIDD trial and a literature review. This also evaluated repeated courses of adalimumab each time the nodule reactivated (every three years) in patients who initially responded.Aims

Bone Morphogenetic Protein 7 (BMP7) is a powerful osteoinductive substance that could stimulate bone formation in difficult conditions including distraction osteogenesis. However, to be effective, large unphysiological doses are required. Blocking the expression of BMP antagonists could amplify the effects of BMP7, allowing smaller doses of BMP7 to be used without altering its osteogenic potential. In this study, BMP7 antagonist Noggin was shown to be upregulated following BMP7 injection in a rabbit distraction osteogenesis model suggesting a role for Noggin in controlling BMP7 activity. Blocking Noggin expression may thus permit smaller doses of BMP7 to be used effectively. Distraction osteogenesis (DO) is an excellent method to form new bone. However, the long duration the external fixator has to be kept on until the new bone consolidates, could lead to numerous problems. BMP7 may accelerate bone formation in DO. However, large doses of BMP7 may be necessary. In this study, we investigated the expression of BMP7 antagonist Noggin in DO. Noggin may control BMP7 activity through a negative feedback mechanism. Blocking Noggin may amplify the effects of BMP7, thus permitting the use of smaller doses of BMP7 effectively in DO. Using smaller doses of BMP7 – while maintaining its powerful effects – may decrease side effects and render this drug more affordable economically. Noggin is normally expressed in DO. Its expression is upregulated by local application of BMP7. Its expression is co-localized to the same cells that express BMP7 and its receptors. The right tibia of sixteen rabbits was lengthened using a uniplanar fixator. The rabbits were divided into two groups: one received seventy-five micrograms recombinant BMP7 and the other
Although periarticular injection plays an important role in multimodal pain management following total hip arthroplasty (THA), there is no consensus on the optimal composition of the injection. In particular, it is not clear whether the addition of a corticosteroid improves the pain relief achieved nor whether it is associated with more complications than are observed without corticosteroid. The aim of this study was to quantify the safety and effectiveness of cortocosteroid use in periarticular injection during THA. We conducted a prospective, two-arm, parallel-group, randomized controlled trial involving patients scheduled for unilateral THA. A total of 187 patients were randomly assigned to receive periarticular injection containing either a corticosteroid (CS group) or without corticosteroid (no-CS group). Other perioperative interventions were identical for all patients. The primary outcome was postoperative pain at rest during the initial 24 hours after surgery. Pain score was recorded every three hours until 24 hours using a 100 mm visual analogue scale (VAS). The primary outcome was assessed based on the area under the curve (AUC).Aims

Animal models have been developed that allow simulation of post-traumatic joint contracture. One such model involves contracture-forming surgery followed by surgical capsular release. This model allows testing of antifibrotic agents, such as rosiglitazone. A total of 20 rabbits underwent contracture-forming surgery. Eight weeks later, the animals underwent a surgical capsular release. Ten animals received rosiglitazone (intramuscular initially, then orally). The animals were sacrificed following 16 weeks of free cage mobilisation. The joints were tested biomechanically, and the posterior capsule was assessed histologically and via genetic microarray analysis.Aims
