Aims. There is conflicting evidence on the safety of intra-articular injections of hyaluronic acid (HA) or corticosteroids (CSs) before total knee arthroplasty (TKA). We performed a meta-analysis of the relationship between intra-articular injections and subsequent infection rates after TKA. Methods. We searched PubMed, EMBASE, and the Cochrane Library for cohort studies that assessed the effect of preoperative injection of drugs into the joint cavity on the infection rate after TKA. The outcomes analyzed included the total infection rate, as well as those for different preoperative injection time periods and different drugs. Results. Eight studies, including 73,880 in the injection group and 126,187 in the control group, met the inclusion criteria. The injection group had a significantly higher postoperative infection rate than the control group (risk ratio (RR) 1.16; 95% confidence interval (CI) 1.07 to 1.27; p < 0.001; I. 2. = 32%). For patients who received injections up to three months preoperatively, the postoperative infection risk was significantly higher than that in the control group (RR 1.26; 95% CI 1.18 to 1.35; p<0.001; I. 2. = 0%). There was no significant difference in the infection rates between the four-to-six-month injection and control groups (RR 1.12; 95% CI 0.93 to 1.35; p = 0.240; I. 2. = 75%) or between the seven-to-12-month injection and control groups (RR 1.02; 95% CI 0.94 to 1.12; p = 0.600; I. 2. = 0%). Conclusion. Current evidence suggests that intra-articular injections of CSs or HA before TKA increase the risk of postoperative infection. Injections administered more than three months before TKA do not significantly increase the risk of infection. Cite this article: Bone Joint Res 2022;11(3):171–179

Aims. Frozen shoulder is a common, painful condition that results in impairment of function. Corticosteroid injections are commonly used for frozen shoulder and can be given as glenohumeral joint (GHJ) injection or suprascapular nerve block (SSNB). Both injection types have been shown to significantly improve shoulder pain and range of motion. It is not currently known which is superior in terms of relieving patients’ symptoms. This is the protocol for a randomized clinical trial to investigate the clinical effectiveness of corticosteroid injection given as either a GHJ injection or SSNB. Methods. The Therapeutic Injections For Frozen Shoulder (TIFFS) study is a single centre, parallel, two-arm, randomized clinical trial. Participants will be allocated on a 1:1 basis to either a GHJ corticosteroid injection or SSNB. Participants in both trial arms will then receive physiotherapy as normal for frozen shoulder. The primary analysis will compare the Oxford Shoulder Score (OSS) at three months after injection. Secondary outcomes include OSS at six and 12 months, range of shoulder movement at three months, and Numeric Pain Rating Scale, abbreviated Disabilities of Arm, Shoulder and Hand score, and EuroQol five-level five-dimension health index at three months, six months, and one year after injection. A minimum of 40 patients will be recruited to obtain 80% power to detect a minimally important difference of ten points on the OSS between the groups at three months after injection. The study is registered under ClinicalTrials.gov with the identifier NCT04965376. Conclusion. The results of this trial will demonstrate if there is a difference in shoulder pain and function after GHJ injection or SSNB in patients with frozen shoulder. This will help provide effective treatment to patients with frozen shoulder. Cite this article: Bone Jt Open 2023;4(3):205–209

Study Design: A prospective evaluation of 40 consecutive patients with sciatica who had ‘Normal’ MRI scans, were further investigated with Nerve Root Injections (NRI), and subsequent surgery in those who had relief of symptoms. Objectives: To evaluate the diagnostic value of NRI’s in the presence of normal MRI scans and to assess the aetiology of the sciatica. Summary of Background Data: Since the advent of MRI scans the use of NRI’s has been in decline as a diagnostic tool. There has been no study in their usefulness when the MRI has been reported as showing no evidence of nerve root compression, and furthermore what the surgical findings were in the patients who went on to exploration. Methods: 40 Patients with sciatica, of minimal duration of one year, in whom the MRI scan had been reported as showing no evidence of nerve root compression by an independent observer, had diagnostic NRI’s performed. Those patients that had reproduction of and subsequent temporary relief of their sciatica had surgery. Outcome Measures: Walking distance, Analgesic Requirements, Sleep disturbance and VAS. Results: Of the 40 patients, 25 had no benefit, 4 patients had permanent relief and 11 had temporary relief. These 11 patients underwent surgery. All patients undergoing surgery were L5 nerve root explorations. In 9 cases the compression was by the ligamentum flavum and in 2 at the foramen. Of the eleven cases operated on 9 had complete relief of symptoms and 2 were unchanged. Conclusions: MRI scans do not show a cause for sciatica in all patients as it is not a dynamic test. In the presence of a normal MRI scan, NRI’s should be performed

Chronic Achilles tendinopathy is characterised by sub-acute inflammation with pro-inflammatory type 1 macrophages (M1), tissue degeneration and consequent partial or total tendon injury. Control of the inflammatory response and M1-to-M2 macrophage polarisation can favour tendon healing both directly and indirectly, by allowing for the regenerative process driven by local mesenchymal stem cells.

Ten patients (3 females and 7 males aged between 32 and 71 years old) with partial Achilles tendon injury were treated with injections of autologous peripheral blood mononuclear cells (PB-MNCs). The cell concentrate was obtained from 100-120 cc of each patient's blood with a selective point-of-care filtration system. PB-MNCs remained trapped in the filter and were injected immediately after sampling. Around 60% of the PB-MNC concentrate was injected directly into the injured area, while the remaining 40% was injected in smaller amounts into the surrounding parts of the Achilles tendon affected by tendinosis.

All patients were evaluated both clinically with the help of the American Orthopaedic Foot & Ankle Society (AOFAS) scale, and radiologically (MRI examination) at baseline and 2 months after the PB-MNC injection. A clinical reassessment with the AOFAS scale was also performed 6 months after the intervention. The rehabilitation protocol implied full weight-bearing walking immediately after the procedure, light physical activity 3-4 days after the injection, and physiotherapist-assisted stretching exercises and eccentric training.

In all patients, functional and radiological signs of tendon healing processes were detected as early as 2 months after a single treatment and the AOFAS scale rose from the initial mean value of 37.5 (baseline) to 85.4 (6 months).

Our preliminary results indicate that regenerative therapies with PB-MNCs can prove useful for partial Achilles tendon injuries as a valid alternative to surgical options, especially when other conservative approaches have failed. Advantages of this therapy include rapid execution, no need for an operating theatre, easy reproducibility, quick recovery and good tolerability regardless of the patient's age (the procedure is not to be performed in subjects who are below 18 years old). Further studies on the topic are recommended to confirm these observations.

An intra-articular steroid injection can be a useful diagnostic tool in patients presenting with debilitating hip pain and radiographically mild osteoarthritis. The clinical and patient reported outcomes associated with patients who have radiographically mild osteoarthritis and undergo total hip arthroplasty (THA) remain poorly studied.

Patients undergoing primary, elective THA at a single academic medical center by a fellowship-trained adult reconstruction surgeon between 2017–2023 were identified. Only those patients who underwent an intra-articular corticosteroid injection into the operative hip within one year of surgery were included. Patients were divided into two cohorts based on the severity of their osteoarthritis as determined by preoperative radiographs; those with Kellgren-Lawrence (KL) grade I-II arthritis were classified as “mild” whereas those with KL grade III-IV arthritis were classified as “severe”. Clinical and patient reported outcomes at final follow-up were compared between cohorts.

The final cohorts included 25 and 224 patients with radiographically mild and severe osteoarthritis, respectively. There were no baseline differences in age, gender or time between intra-articular corticosteroid injection and THA between cohorts. There were no significant differences in the preoperative or postoperative HOOS JR values between patients with mild or severe arthritis (all p>0.05). There were no significant differences in the change in HOOS JR scores from the preoperative to final follow-up timepoints between cohorts. There were no significant differences in the percentage of patients who achieved the minimal clinically important difference (MCID) on the HOOS JR questionnaire between cohorts.

Patients with radiographically mild osteoarthritis who feel relief of their hip pain following an intra-articular corticosteroid injection report similar preoperative debility and demonstrate similar improvements in patient reported outcome scores following THA compared to patients with radiographically severe osteoarthritis.

Abstract

Objectives

Intra-articular corticosteroid injections (IACIs) are a well-established non-surgical treatment for the symptoms of osteoarthritis (OA), which can provide short-term improvements in pain, disability and quality of life (QoL). Many patients receive recurrent IACIs as temporary relief of their symptoms. Longer-term outcomes for recurrent IACIs remain less well-researched. This meta-analysis aimed to investigate the longer-term risks and benefits of IACIs beyond 3 months.

Methods

We searched MEDLINE, EMBASE, and CENTRAL from inception to January 07, 2021, for randomised controlled trials (RCTs) where patients with OA had received recurrent IACIs. Our primary outcomes were pain and function. Secondary outcomes included QoL, disease progression, radiological changes, and adverse events. Mean differences with 95% confidence intervals were reported.

Abstract

Background

Lateral and medial epicondylitis, more commonly known as Tennis and Golfer's elbow, can cause chronic pain and significant functional impairment in working-age patients. For patients with refractory epicondylitis, platelet rich plasma (PRP) of which ACP is a type, is commonly used as an alternative to surgical intervention, but its efficacy is unproven.

Objective

To assess the mid-term outcomes of ultrasound guided ACP injections for patients with refractory epicondylitis who have failed conventional conservative treatment.

Background

Bacteriophages are natural viruses of interest in the field of PJI. A paper previously reported the PhagoDAIR procedure (use of phages during DAIR) in three patients with PJI for whom explantation was not desirable. As the need to isolate the pathogen before surgery to perform phage susceptibility testing is a strong hindrance for the development of this procedure, we developed post-operative phage injections using ultrasound, in patients infected with S. aureus and/or P. aeruginosa who were eligible for the PhagoDAIR procedure, but for whom phages were not available at the time of surgery.

Materials/Methods

We performed a single center, exploratory, prospective cohort study including patients with knee PJI who received phage therapy with ultrasound after performance of a DAIR or a partial prosthesis exchange. All patients had PJI requiring conservative surgery and suppressive antimicrobial therapy (SAT) as salvage procedure. Each case was discussed in multidisciplinary meetings in agreement with French health authority, based on the clinical presentation, and the phage susceptibility testing. The cocktail of highly concentrate active phages (5 mL; about 10e9 PFU/mL) was extemporaneous prepared and administered three times directly into the joint using sonography (1 injection per week during 3 weeks) during the postoperative period, before switching antibiotics to SAT.

Introduction

We compared ultrasound guided methylprednizolone-lidacaine infiltrations around inflammatory area of plantar aponeurosis with systematic use of NSAID'S. Also, we investigated the reliability of the sonographic criteria (a. swelling of aponeurosis more than 20% in comparison to the healthy foot, b. effusion around aponeurosis, c. calcium deposits) most used to identify plantar fasciitis in clinically suspicious patients.

Methods

A prospective randomised controlled clinical trial, including 28 patients (mean age: 47 years, range: 36–65 years, 85% females) with typical clinical symptoms of plantar fasciitis. All of these patients undertook a soft tissue ultrasonography of the plantar aponeurosis, without Doppler. Then, we randomly divided our sample in 2 groups, group A (14 patients) and group B (14 patients). In group A patients we performed an ultrasound guided injection –in transverse view- around the swollen part of aponeurosis, while we managed group B patients with per os NSAID's treatment (meloxicam 15 mg, once per day) for 2 weeks.

Intra-articular injections of human mesenchymal stromal cells (MSCs) and platelet-rich plasma (PRP) have been intensively investigated as therapies for knee osteoarthritis (OA) with positive outcomes. In this work we evaluated weather a combination of the treatments (MSCs + PRP) would be beneficial compared to MSCs alone (MSCs) and standard corticosteroid injection (Control group). Forty seven patients (24 males and 23 females; 53.3 ± 10.7 years old) with radiographic symptomatic knee OA (Dejour grades II–IV) were randomized to receive intra-articular injections of MSCs (n = 16), MSCs + PRP (n = 14) or corticosteroid (n=17). MSCs were obtained after mononuclear cells separation from bone marrow aspiration collected from both posterior iliac crests using Sepax automated closed system and expanded in culture until reaching the number of 4 × 107. PRP was obtained by double-centrifugation of whole blood according to a protocol developed in house. After 12 months follow-up, the MSCs and MSCs+PRP groups achieved higher percentages of expected improvement when comparing to the corticosteroid group for the KOOS-symptoms, pain, function and daily living, domains and global score. For the population older or equal to 60 years old the MSCs+PRP group showed significant superiority for the KOOS-ADL domain at 12 months. Cytokines quantification evidenced anti-inflammatory aspects of the treatments. This work evidences the safety and efficacy of intra-articular injection of MSCs for the treatment of early knee OA, with greater improvement with PRP addition particularly to the older population.

Introduction

Lateral epicondylitis, also known as “tennis elbow,” is a degenerative disorder of the common extensor origin of the lateral humeral epicondyle. The mainstay of treatment is non-operative and includes physiotherapy, activity modification, bracing, nonsteroidal anti-inflammatory drugs, and injections. There is a subgroup of patients however who do not respond to non-operative measures and require operative intervention.

Methods

We conducted a retrospective review of prospectively collected data to assess whether the introduction of PRP injections for lateral epicondylitis led to a reduction in patients subsequently undergoing surgical release.

Objection

Multimodal local periarticular injection can be effective for pain management after total knee arthroplasty. We have investigated to get the similar results after total hip arthropasty.

Methods

Sixty patients undergoing total hip arthroplasy were divided to two groups. One were with multimodal local periarticular injection(Group M) and the other were with single intraarticular injection Group C, conventional method. We injected a “cocktail” agents into the soft tissue (capsule, synovium, muscle, subcutaneous fat tissue, skin) around the implants. Those were contained Morphinesulfate, Ropivacaine, Adrenaline, Methylpredonisolone, Ketoprofen, and Normal saline. We compared the VAS(at rest and during walking), the duration of the mobilization and active SLR, and any complicaions.

Following arthroscopic arthrolysis for frozen shoulder, steroid injections may become necessary to improve ongoing pain and facilitate stretching exercises. The aim of this study was to evaluate the rate of steroid injections needed post-arthroscopic arthrolysis of frozen shoulder.

Case series review carried out in a District General Hospital in UK. 30 consecutive patients who had arthroscopic arthrolysis under the care of the senior author were included. Patients’ records were analysed to identify the number of steroid injections administered post-operatively.

11 males and 19 females were examined, aged 46–83 years old (mean 56.1). 7 patients were diabetic. 10 patients (33.3%) received steroid injections post-operatively, with 8 of them receiving the injection within the first 6 post-operative months. The average post-operative time of steroid injection was 9.8 months. There was no association between diabetes and administration of a post-operative steroid injection P>0.01.

Following arthroscopic arthrolysis a substantial proportion of patients may require one or more steroid injections to help pain and facilitate stretching exercises and physiotherapy. This study showed that 1 in 3 frozen shoulders treated with arthroscopic arthrolysis may need a subsequent steroid injection in the first year post surgery. Patients should be counselled preoperatively with regards to that, and be warned that arthroscopic arthrolysis is only the first step in the treatment pathway leading to recovery.

The entirety of the patient experience after contemporary total knee and total hip replacements in 2016 is markedly different from that encountered by patients just a decade ago. Ten years ago most patients were treated in a traditional sick-patient model of care and because they were assumed to require substantial hospital intervention, many cumbersome and costly interventions (e.g. indwelling urinary catheters, patient-controlled-analgesic pumps, autologous blood transfusion, continuous passive motion machines) were a routine part of the early post-operative experience. Today the paradigm has shifted to a well-patient model with a working assumption that once a patient has been medically optimised for surgery then the intervention itself, hip or knee replacement, will not typically create a sick-patient. Instead it is expected that most patients can be treated safely and more effectively with less intensive hospital intervention. While as orthopaedic surgeons we are enamored with the latest surgical techniques or interesting technologies most busy surgeons recognise that advances in peri-operative pain management, blood management, and early-mobilization therapy protocols account for the greatest share of improvements in patient experience over the past decade.

One can think pragmatically to get ahead and stay ahead of 3 predictable physiologic disturbances that adversely impact rapid recovery after knee and hip replacement: fluid/blood loss; pain; and nausea. The modern orthopaedic surgeon and his/her care team needs a simple strategy to proactively, not reflexively, manage each of those 3 predictable impediments to early recovery. Those surgical teams that routinely get ahead and stay ahead in each of those areas will routinely witness faster recovery, lower costs and greater patient satisfaction and that is clearly a win for patient and surgeon alike.

Effective pain management improves patient satisfaction, decreases hospital stay, and facilitates discharge to home. Today's emphasis is on a multi-modal strategy that minimises the use of opioids. Most protocols use pre-operative medications including an NSAID, acetaminophen, an oral opioid and some include gabapentin. Regional anaesthesia is typically preferred over general. Both peripheral nerve blocks and periarticular local anesthetic cocktail injections have proved as effective adjuncts in decreasing early post-operative pain. Post-operative oral medications delivered on a schedule, not just as needed, often include acetaminophen, an NSAID and some included gabapentin. Oral and parenteral opioids are reserved for breakthrough pain.

Backpain is a common cause of patient referral to pain clinics. Around 120 000 patients with back pain are seen in UK Pain Clinics every year. Facet joint injections are a commonly used treatment modality. However there is considerable controversy regarding their efficacy. Most of the evidence supporting the use of injections is anecdotal, rather than being based on randomised studies.

We carried out a prospective study to assess the efficacy of facet joint injections in relieving chronic low back pain. Our study group comprised 41 patients (57% females, 43% males). Patients completed the Oswestry Disability Index (ODI) and marked their pain levels on a Visual Analogue Scale (1 to 10).

We found that though the pain score improved from 6.9 to 4.3, there was only a marginal improvement in the ODI from 52.5 to 50.8. Overall 85 % of patients experienced some improvement, while 15% felt their symptoms had worsened after the injections. One of the most significant findings of this study was the fact that the improvement in most patients lasted only for an average of three weeks. This is significantly less than most previous studies indicate. Interestingly, inspite of this limited improvement, almost all patients expressed the desire to be placed back on the list for repeat injections.

Our study demonstrated a beneficial short term effect of facet joint injections. In our opinion, they are a reasonable adjunct to non operative treatment of chronic backpain.

Knee osteoarthritis is a common, debilitating condition. Intra articular corticosteroid injections are a commonly used non-operative treatment strategy. Intra articular hip injection with Ketorolac (an NSAID) has proven to be as efficacious as corticosteroids. No prior study compares the efficacy of Ketorolac relative to corticosteroids for relief of discomfort in knee osteoarthritis. The study design was a single centre double blinded RCT. Severity of osteoarthritic changes were graded on plain film weightbearing radiographs using the Kellgren and Lawrence system. Injection was with either 30mg Ketorolac or 40mg Methylprednisolone, given by intra-articular injection, in a syringe with 5mls 0.5% Marcaine. Pre-injection clinical outcomes were assessed using the Numerical Pain Score (NPS), WOMAC, and Oxford knee scores. Patients' NPS scores were assessed at Day 1 and Day 14 post-injection. An assessment of all clinical outcomes took place in clinic at six weeks. There were 72 participants (83 knees) in the study. No patients were lost to follow-up. Mean age was 62.66 years (Range 29–85). 42 knees received a corticosteroid injection, 41 a NSAID injection. Mean Kellgren and Lawrence score was 3.1. There was no significant difference in pre-injection clinical scores in either group. There was a significant improvement of NPS on Day 1 and 14 in both injection groups(p<0.05). These improved pain scores were sustained at 6 weeks in both groups. WOMAC and Oxford Knee Scores showed a statistically significant improvement in the corticosteroid group. WOMAC scores showed significant improvement in the NSAID group, however these improvements didn't achieve statistical significance using the Oxford Knee Score. Corticosteroid or NSAID injectate are a safe and effective non-operative treatment strategy in the patient with knee osteoarthritis. Ketorolac appears to provide effective medium-term improvement of pain and clinical scores. Further follow-up is recommended to investigate if this trend in sustained.

Introduction

Rotator cuff healing after an arthroscopic repair is discussible because of the high incidence of failures. Among biologic augmentations currently used, platelet-rich plasma (PRP) is one of the most applied, supposed to enhance and accelerate the healing process in different musculoskeletal disorders. However, the evidence supporting its successful administration is still lacking, especially in the field of the rotator cuff repair. Our purpose is to clarify if the recovery is accelerated and the integrity of repaired construct is increased in patients undergoing PRP injections after arthroscopic repair of the rotator cuff.

Patients & Methods

Thirty-eight patients with full-thickness rotator cuff tears have been enrolled after they had been informed about the use of PRP and the timing of its application postoperatively. Seventeen patients underwent arthroscopic rotator cuff repair and PRP injections (3 injections at 10 days each other), 21 underwent arthroscopic rotator cuff repair without PRP injections. Outcomes were assessed preoperatively, at 3, 6, 12, and minimum 16 months after surgery (average 17.7 +/− 1.7 months). Constant system, the University of California at Los Angeles (UCLA) system and a Visual Analogue Scale (VAS) scale were used; range of motion and strength in all planes were also assessed. The healing of the repair was assessed at magnetic resonance imaging at a minimum follow up of 6 months from surgery. All patients had the same rehabilitation protocol.

Aim

We outline a treatment protocol for subjects with chronic periprosthetic joint infections (PJI) who elected not to have surgery. We developed a method of serial “fluid-depleting” aspirations with intra-articular gentamycin injections to affect the population of the biofilm community. We have experienced many treatment failures, as expected, but have also had a group of subjects who responded exceptionally well, requiring no surgical intervention. Our longest follow-up is 10 years.

Method

From June 2009 to December 2018, 372 clinical cases of chronic PJI involving primary and revision TKA and THA were treated. Of these, 25 subjects were treated with an active suppression protocol, in lieu of surgery. The protocol entailed frequent aspirations and intra-articular antibiotic injections to quell the PJI inflammatory response. All aspirations were performed by the treating surgeon in the orthopaedic clinic without fluoroscopic guidance. Based on a subject's response to the protocol, he/she was identified as 1 of 3 classifications: 1) Ongoing Treatment – Biofilm Trained (OTBT), 2) Ongoing Treatment – Biofilm Untrained (OTBU), and 3) Treatment Failure (TF). OTBT subjects showed no clinical signs of infection. Serum biomarkers (CRP, ESR) remained consistently normal and subjects were not on oral suppressive antibiotics. Aspiration analysis and cultures remained negative. Maintenance treatment consisted of a fluid-depleting aspiration with an intra-articular gentamycin injection every 12–16 weeks. OTBU subjects showed improved clinical symptoms, lowered serum biomarkers, and lowered WBC counts, but still demonstrated objective signs of infection. TF subjects did not respond to the protocol and showed unchanged/worsening clinical symptoms.

Introduction: The management of spasticity of children with cerebral palsy is often complex and challenging. Effective treatment requires a multidisciplinary approach involving paediatricians, orthotists, occupational therapists, physiotherapists and orthopaedic surgeons. Botulinum toxin A therapy in the lower limb has been shown to relieve spasticity and to improve the function in the short term. However, the use of Botulinum toxin A in the upper limb remains controversial.

Aim: To assess any improvement following upper limb Botulinum toxin A injections and to evaluate patient’s and parents’ expectation and satisfaction of the procedure.

Method: During 2007 a total of 36 spastic cerebral palsy patients underwent 47 episodes of Botulinum toxin A injections to the upper limb. There were 22 male and 14 female with a mean age of 6 years old. A questionnaire was devised to assess the outpatient consultation, peri-operative care and the post-operative outcome. Subjective improvement and the patient’s and parents’ evaluation of the procedure were also recorded.

Results: Good to excellent results were achieved in most areas. Daily activities were improved by 52% with an average duration of 4 months. The majority of the patient achieved their expectation. Most patients/parents were satisfied with the procedure and would consider further injections.

Conclusions: Botulinum toxin A injection to the upper limb was generally well received with good short term results. Most would consider further injections.
