Objectives. Intra-articular injections of local anaesthetics (LA), glucocorticoids (GC), or hyaluronic acid (HA) are used to treat osteoarthritis (OA). Contrast agents (CA) are needed to prove successful intra-articular injection or aspiration, or to visualize articular structures dynamically during fluoroscopy. Tranexamic acid (TA) is used to control haemostasis and prevent excessive intra-articular bleeding. Despite their common usage, little is known about the cytotoxicity of common drugs injected into joints. Thus, the aim of our study was to investigate the effects of LA, GC, HA, CA, and TA on the viability of primary human chondrocytes and tenocytes in vitro. Methods. Human chondrocytes and tenocytes were cultured in a medium with three different drug dilutions (1:2; 1:10; 1:100). The following drugs were used to investigate cytotoxicity: lidocaine hydrochloride 1%; bupivacaine 0.5%;
Background. Infiltration is considered the first treatment option for symptomatic Morton's neuroma and can be performed with various medications. The aim of this study was to compare the effects of hyaluronic acid infiltration versus corticosteroid injection in the treatment of Morton's neuroma. Methods. A randomised clinical trial was conducted with 46 patients (50 feet) diagnosed with Morton's neuroma. After randomisation, the control group (CG) received three injections (one per week) of
In osteoarthritis, chondrocytes acquire a hypertrophic phenotype that contributes to matrix degradation. Inflammation is proposed as trigger for the shift to a hypertrophic phenotype. Using in vitro culture of human chondrocytes and cartilage explants we could not find evidence for a role of inflammatory signalling activation. We found, however, that tissue repair macrophages may contribute to the onset of hypertrophy (doi: 10.1177/19476035211021907) Intra-articularly injected

This was a double-blind randomised controlled study. The objective of this study was to determine the cause of post-injection pain after peri-articular steroid injection. Approval for this study was granted by the hospital’s Ethics Committee. Selection criteria included all patients undergoing a peri-articular injection under the care of the senior author. Patients who elected to be in this study gave their consent following a detailed explanation of the study and provision of a patient information leaflet. The enrolled patients were randomised into one of two groups. Group A received a standard
Summary. Corticosteroids (CS) are commonly administered by intra-articular injection to control the symptoms of osteoarthritis; however, CSs also suppress articular chondrocyte matrix synthesis. Both
Joint injuries often result in inflammation and cartilage defects. When inflamed, the synovium secretes factors that prevent successful cartilage repair by inhibiting chondrogenic differentiation of progenitor cells. In particular the pro-inflammatory macrophages in the synovium are indicated to contribute to this anti-chondrogenic effect. Thus, we aimed to counteract the anti-chondrogenic effect of inflamed synovium by modulating synovial inflammation and its macrophages. Synovium tissue obtained from osteoarthritic patients undergoing a total knee replacement was cut into explants and cultured for 72 hours +/− 1 µM of the anti-inflammatory drug
Introduction. Adhesive capsulitis is a common condition causing painful limitation of shoulder movements. Hydrodistension is one of the techniques, is well recognised and has shown good outcomes. However, the results of hydro distension release in secondary adhesive capsulitis are not clear. Patients and Methods. This is a retrospective study on patients undergoing hydro distension release. Patients who had any surgical intervention were classed as secondary whilst the rest were included in the primary group. The hydro distension is a standard technique where in the senior author locates the gleno humeral joint using radio opaque dye, followed by injection of 20 mls 0.5% L-bupivacaine and 80 mg of
Steroid injections are used for subacromial pain syndrome and can be administered via the anterolateral or posterior approach to the subacromial space. It is not currently known which approach is superior in terms of improving clinical symptoms and function. This is the protocol for a randomized controlled trial (RCT) to compare the clinical effectiveness of a steroid injection given via the anterolateral or the posterior approach to the subacromial space. The Subacromial Approach Injection Trial (SAInT) study is a single-centre, parallel, two-arm RCT. Participants will be allocated on a 1:1 basis to a subacromial steroid injection via either the anterolateral or the posterior approach to the subacromial space. Participants in both trial arms will then receive physiotherapy as standard of care for subacromial pain syndrome. The primary analysis will compare the change in Oxford Shoulder Score (OSS) at three months after injection. Secondary outcomes include the change in OSS at six and 12 months, as well as the Pain Numeric Rating Scale (0 = no pain, 10 = worst pain), Disabilities of Arm, Shoulder and Hand questionnaire (DASH), and 36-Item Short-Form Health Survey (SF-36) (RAND) at three months, six months, and one year after injection. Assessment of pain experienced during the injection will also be determined. A minimum of 86 patients will be recruited to obtain an 80% power to detect a minimally important difference of six points on the OSS change between the groups at three months after injection.Aims

Local infiltration analgesia (LIA) is promoted as an effective treatment modality for pain control after total knee arthroplasty (TKA) (1). A mixture of drugs is used to provide a multimodal analgesic effect. Previous studies reported that the use of these drugs is safe. After we carefully implemented a LIA study protocol in our practice, concerns raised about patient safety with probably higher infection rates. This forced us to perform an interim analysis after the first 58 cases. 58 patients underwent a unilateral TKA with a standardised LIA protocol (2), which consisted of a mixture of ropivacaine, epinephrine, and
Dupuytren’s contracture is characterized by increased fibrosis of the palmar aponeurosis, with eventual replacement of the surrounding fatty tissue with palmar fascial fibromatosis. We hypothesized that adipocytokines produced by adipose tissue in contact with the palmar aponeurosis might promote fibrosis of the palmar aponeurosis. We compared the expression of the adipocytokines adiponectin and leptin in the adipose tissue surrounding the palmar aponeurosis of male patients with Dupuytren’s contracture, and of male patients with carpal tunnel syndrome (CTS) as the control group. We also examined the effects of adiponectin on fibrosis-related genes and proteins expressed by fibroblasts in the palmar aponeurosis of patients with Dupuytren’s contracture.Aims

Introduction. Total knee arthroplasty is a painful operation. Peri-articular local anesthetic injections reduce post-operative pain and assist recovery. It is inconclusive whether intra-operative injections of peri-articular corticosteroids are of benefit. Clinical Question: In patients with osteoarthritis who are undergoing TKA, does the addition of high or low dose corticosteroid to peri-articular injections of local anesthetic and adrenaline improve post-operative pain and range of motion?. Methods. A prospective, randomized, double-blinded study was undertaken to assess the efficacy of adding peri-articular corticosteroids to intra-operative, peri-articular high volume local anaesthetic in post-operative pain management following TKA. 127 patients were randomised into three groups receiving local anaesthetic alone (control) or either low dose (40 mg) or high dose (80 mg) peri-articular corticosteroid plus local anaesthetic. Primary outcomes included ROM and visual analog pain scores (VAS). Pain was defined as the worst pain lasting for more than 20 minutes, measured at both rest (RVAS) and during activity (AVAS). Results. There were no significant between-group differences for age, body mass index (BMI), pre-operative ROM or pre-operative pain scores. There were no statistically significant differences in primary or secondary outcomes between the groups. This was the case at all time points. Analysis of non-significant trends demonstrated a 17.7% reduction in RVAS between the control group and high dose steroid group at 12-weeks. This trend was also apparent at 2 and 6 weeks. There was no trend towards decreased total morphine equivalents (or any other secondary outcome) between the control and high dose groups. Discussion. Corticosteroids have been postulated to facilitate post-operative ROM and reduce pain after TKA. However we were unable to show any significant clinical effect of peri-articular
Aim: This study aims to quantify pain relief and quality-of-life benefit from a diagnostic SIJ injection. Methods: 50 consecutive patients were retrospectively recruited with unilateral low back pain, pain mapping compatible with a sacroiliac origin, tenderness over the SIJ, and no obvious source of pain in the lumbar spine. These were selected for a diagnostic SIJ injection. A structured questionnaire was completed both pre- and post-injection. Median patient age was 63. All patients were injected under fluoroscopic imaging with
Introduction: Intra-articular steroid injection has been widely used for relief of pain in osteoarthritis. Recent studies show an increasing rate of infection in these patients following hip arthroplasty. We have reviewed our cohort of patients to see if they are susceptible to higher infection rate. Methods: We reviewed a cohort of 167 consecutive hips that had at least one injection with a 40mg

We describe results of a new ‘two needle technique’ of selective nerve root blocks done through posterior triangle of neck in the management of cervical radiculopathy with 2 year results. Methods: Patients presenting with cervical radiculopathy were evaluated clinically and radiologically and were initially managed with supervised physiotherapy, analgesics and rest. Selective cervical nerve root block was offered to the patients, who did not respond to conservative management. The procedure was performed as a day case, under local anesthesia, with image intensifier guidance, using ‘two needle technique’. A thinner needle is rail-roaded through the lumen of large diameter guide needle to reach the target nerve root foramen and a mixture of Bupivacaine and
