RESUMO
Trapeziometacarpal osteoarthritis (carpometacarpal arthritis / CMC-1 arthritis) is a common cause of chronic thumb pain and may significantly worsen patients' quality of life. The thumb is the most important digit of the hand. A diagnostic-therapeutic algorithm for CMC-1 arthritis should be widely known and based on up-to-date evidence-based medical knowledge. The literature describes many medical and surgical treatment approaches. The methods used vary between hospitals and clinics. They also depend on patients' financial capabilities and many other factors.Medical (conservative) treatment appears to be effective in 60% of cases, in particular when the synergy of combining several treatment methods is taken advantage of. The most commonly performed surgical procedures in CMC-1 arthritis fall into two major groups, namely trapeziectomy or arthroplasty. However, there is no proof of superiority of one surgical treatment method over the others, and all of them have their advantages and disadvantages.This paper aims to present the most up-to-date knowledge about: (1) conservative and (2) surgical treatments for CMC-1 arthritis and (3) to propose a diagnostic-therapeutic algorithm for this condition. It is based on the latest literature (mainly works published in the last 5 years) acquired from databases such as PubMed, Clinical Key and Science Direct. The article is the second of a two-part series that presents a diagnostic-therapeutic algorithm for CMC-1 arthritis. The authors believe that it may contribute to broadening knowledge about CMC-1 arthritis, optimizing the therapeutic process and improving care for patients with CMC-1 arthritis in Poland.

INTRODUCTION: Chronic pain in hemophilic patients is due to joint degeneration associated with hemophilic arthropathy. In addition to appropriate hematological treatment (primary prophylaxis), pharmacologic management and Physical Medicine and Rehabilitation should be indicated. When such measures are not sufficient, intraarticular injections (IAIs) of hyaluronic acid (HyA) may be considered. AREAS COVERED: In order to determine whether IAIs of HyA are effective in terms of pain relief in individuals with painful moderate hemophilic arthropathy, a PubMed and Cochrane Library search using 'hemophilia hyaluronic acid' as keywords was performed on 18 July 2023. EXPERT OPINION: In a study of individuals with hemophilic arthropathy (elbows, knees and ankles), 91% of them improved pain after a mean follow-up of 6 years. In another study of individuals with knee arthropathy, after a 7-year follow-up 82% reported an improvement in pain. As for hemophilic ankle arthropathy, in a study 67% of patients showed relief of joint pain at 6-month follow-up. Although the literature on the subject is very heterogeneous and difficult to interpret, it appears that IAIs of HyA can relieve the joint pain of painful moderate hemophilic arthropathy for months. Moreover, the IAIs can be repeated every 6-12 months.

Objective We studied the microbiological profile of periprosthetic knee infections treated in a Brazilian tertiary hospital. Methods The study included all patients undergoing revision surgery for total knee arthroplasty (RTKA) between November 2019 and December 2021, with a diagnosis of periprosthetic infection confirmed per the 2018 International Consensus Meeting (ICM) criteria. Results Sixty-two patients had a periprosthetic joint infection (PJI) per the 2018 ICM criteria. Cultures were monomicrobial in 79% and polymicrobial in 21% of cases. The most frequent bacterium in microbiological tissue and synovial fluid cultures was Staphylococcus aureus , observed in 26% of PJI patients. Periprosthetic joint infection with negative cultures occurred in 23% of patients. Conclusion Our results show the following: i) a high prevalence of Staphylococcus as an etiological agent for knee PJI; ii) a high incidence of polymicrobial infections in early infections; iii) the occurrence of PJI with negative cultures in approximately one fourth of the subjects.

Sonography and specific shoulder positions allow for injections into both the long head of the biceps tendon sheath (LHBTS) and the subacromial space (SS) with one needlestick. We validated this technique using cadavers. An experienced proceduralist injected latex solution into 12 unembalmed cadaveric shoulders, aiming for the LHBTS and SS, using an ultrasound-guided injection technique that employs a single-needle entry point. An experienced surgeon dissected each specimen and graded latex location as: (1) completely accurate (in both the SS and LHBTS); (2) partially accurate (in either the SS or LHBTS); (3) accurate with overflow (in both locations, but also elsewhere); (4) partially accurate with overflow (in either location, but also somewhere else); or (5) completely inaccurate (no latex in either location). All 12 ultrasound-guided injections using the technique accurately placed latex into both LHBTS and SS (100% accuracy). Latex was also found in adjacent regions after two (17%) injections: one within the shoulder joint and one within the deltoid musculature. This newly described technique allows highly accurate access to the LHBTS and SS with single-needle entry. This technique could become a favored alternative to subjecting patients to two needlesticks and preparing separate injections to address often concomitant pathologies.

BACKGROUND: Sacro-iliac joint (SIJ) pain is an often-misdiagnosed cause (up to 30% cases) of atypical low back pain (LBP) that might be treated with a wide range of conservative interventions. However, Platelet-Rich-Plasma (PRP) ultrasound-guided injections at SIJ level in subjects with mitochondrial disorders have not yet been investigated. CASE PRESENTATION: A 52-year-old Caucasian male with fluoroquinolone-related mitochondrial dysfunction referred to a Physical Medicine and Rehabilitation Outpatient, complaining of severe SIJ pain (Numeric Pain Related Scale, NPRS=8). We performed two bilateral PRP ultrasound-guided injections at the sacro-iliac level. PRP is a simple, efficient, and minimally invasive approach. After the first PRP injection, there was a considerable reduction of pain (NPRS=8 vs 5). The second PRP infiltration was performed after 2 weeks and in both cases no adverse events. At the 6-month follow-up evaluation, the patient showed good physical recovery, with the absence of pain (NPRS=0). CONCLUSION: To the best of our knowledge, this is the first report in the literature assessing the safety and effectiveness of PRP ultrasound-guided injections for SIJ pain in a patient affected by mitochondrial disorders. Thus, this case report might have relevant clinical implications in the treatment of SIJ pain in patients affected by this rare pathological condition, albeit further observational studies are warranted to confirm these findings.

Cervical pain is a common symptom among the general population. When conservative strategies fail to provide pain relief, cervical spine injections may be considered. Compared with cervical surgery, cervical injections have low major complications and, with the right indication, have demonstrated good results. Traditionally, these types of procedures have been performed under fluoroscopy; however, in recent years, ultrasound has become a more common imaging modality to guide spinal injections. Although ultrasound presents an excellent quality image for soft tissue and allows âthe observation of vascular tissues, nerves, and the contour of bone surfaces, the cervical region has a complicated neurovascular network and a comprehensive understanding of the cervical sonoanatomy should remain as the basis before one can plan cervical ultrasound-guided intervention. This paper aims to show the advantages of ultrasound in facilitating the performance of cervical spine procedures, including facet joint injections, medial branch blocks, and selective nerve root blocks; analyze the sonoanatomy and landmarks of commonly intervened cervical structures; and illustrate how these procedures can be performed safely and precisely under ultrasound guidance.
RESUMO
Temporomandibular joint osteoarthritis (TMJ OA) is a low-inflammatory disorder with multifactorial etiology. The aim of this review was to present the current state of knowledge regarding the mechanisms of action and the efficacy of hyaluronic acid (HA), corticosteroids (CS) and platelet-rich plasma (PRP) in the treatment of TMJ OA.: The PubMed database was analyzed with the keywords: "(temporomandibular joint) AND ((osteoarthritis) OR (dysfunction) OR (disorders) OR (pain)) AND ((treatment) OR (arthrocentesis) OR (arthroscopy) OR (injection)) AND ((hyaluronic acid) OR (corticosteroid) OR (platelet rich plasma))". After screening of 363 results, 16 studies were included in this review. Arthrocentesis alone effectively reduces pain and improves jaw function in patients diagnosed with TMJ OA. Additional injections of HA, either low-molecular-weight (LMW) HA or high-molecular-weight (HMW) HA, or CS at the end of the arthrocentesis do not improve the final clinical outcomes. CS present several negative effects on the articular cartilage. Results related to additional PRP injections are not consistent and are rather questionable. Further studies should be multicenter, based on a larger group of patients and should answer the question of whether other methods of TMJ OA treatment are more beneficial for the patients than simple arthrocentesis.

Objective: To evaluate the benefits of hyaluronic acid intraarticular injection (HA IAI), in conjunction with minimally invasive surgery (arthrocentesis or arthroscopy), as a therapeutic option for temporomandibular joint disorders.Methods: An electronic search in PubMed, Cochrane Library, and Scopus databases was conducted in order to answer the following PICOS question: "In clinical trials with patients treated with arthroscopy or arthrocentesis, did the subsequent use of HA IAI provide a better control of postoperative pain and temporomandibular joint function compared to those patients who did not receive it?"Results: Following PRISMA criteria, six randomized controlled clinical trials were selected. HA IAI showed significant differences in terms of pain reduction in three of them and improvement of mandibular function in two, compared to the control group.Conclusion: Based on scientific evidence, the level of recommendation found regarding this type of intervention is type B (recommendation based on inconsistent or limited-quality patient-oriented evidence).
RESUMO
OBJECTIVE: Knee osteoarthritis (OA) is a frequent degenerative disease representing an important health and economic burden. Symptomatic medical treatments available include intra-articular (IA) injections of corticosteroids (GC) but their efficacy and safety profile are debated. METHODS: We performed a systematic literature review (SLR) and a meta-analysis (MA) of randomized controlled trials (RCTs) assessing the effect of IA GC injections for knee OA. The effect of the interventions on pain and function was extracted from the single studies and pooled. Standardized mean differences (SMD) are reported. RESULTS: Of 520 studies screened, 23 were included in the SLR and 15 subsequently included in the MA. IA GC showed a trend towards a superior effect compared to control on both pain (SMD -0.61 (95% CI: -1.25, 0.03)) and function (SMD -1.02 (95% CI: -2.14, 0.10)) in short term follow-up (≤6 weeks), while long term follow-up (≥24 weeks) analysis showed a trend towards superiority of controls (IA HA, IA NSAID, physiotherapy) for pain (SMD 0.68 (95% CI: -0.11, 1.47)) and function (SMD 0.88 (95% CI: -0.36, 2.12). There were no differences between interventions in medium term (>6 weeks &<24 weeks). CONCLUSION: In this work, IA GC injections reduced pain and improved function early after administration (≤6 weeks) compared to placebo; while this result was no longer statistically significant with other comparators (IA hyaluronic acid or physiotherapy). Other interventions seem to be more efficient in the long term (≥24 weeks) but this effect was largely driven by single studies with large effect sizes.

OBJECTIVES: To quantify the placebo effect of intraarticular injections for knee osteoarthritis in terms of pain, function, and objective outcomes. Factors influencing placebo effect were investigated. DESIGN: Meta-analysis of randomized controlled trials; Level of evidence, 2. PubMed, Web of Science, Cochrane Library, and grey literature databases were searched on January 8, 2020, using the string: (knee) AND (osteoarthritis OR OA) AND (injections OR intra-articular) AND (saline OR placebo). The following inclusion criteria were used: double-blind, randomized controlled trials on knee osteoarthritis, including a placebo arm on saline injections. The primary outcome was pain variation. Risk of bias was assessed using the RoB 2.0 tool, and quality of evidence was graded following the GRADE (Grading of Recommendations Assessment, Development and Evaluation) guidelines. RESULTS: Out of 2,363 records, 50 articles on 4,076 patients were included. The meta-analysis showed significant improvements up to the 6-month follow-up: Visual Analogue Scale (VAS)-pain -13.4 mean difference (MD) (95% confidence interval [CI]: -21.7/-5.1; P < 0.001), Western Ontario and McMaster Osteoarthritis Index (WOMAC)-pain -3.3 MD (95% CI: -3.9/-2.7; P < 0.001). Other significant improvements were WOMAC-stiffness -1.1 MD (95% CI: -1.6/-0.6; P < 0.001), WOMAC-function -10.1 MD (95% CI: -12.2/-8.0; P < 0.001), and Evaluator Global Assessment -21.4 MD (95% CI: -29.2/-13.6; P < 0.001). The responder rate was 52% (95% CI: 40% to 63%). Improvements were greater than the "minimal clinically important difference" for all outcomes (except 6-month VAS-pain). The level of evidence was moderate for almost all outcomes. CONCLUSIONS: The placebo effect of knee injections is significant, with functional improvements lasting even longer than those reported for pain perception. The high, long-lasting, and heterogeneous effects on the scales commonly used in clinical trials further highlight that the impact of placebo should not be overlooked in the research on and management of knee osteoarthritis.

Los esteroides intrarticulares (CS IA) se utilizan con frecuencia para el tratamiento del dolor de los pacientes con artrosis (OA) (tanto de rodilla como cadera), sobre todo en fases tempranas, con un comienzo de acción rápido proporcionando una mejoría a corto plazo (1-6 semanas). Los CS IA no mejoran clínica ni significativamente la función articular de rodillas o caderas (rigidez, distancia caminada ni movilidad articular) ni la calidad de vida. La eficacia de los CS IA en la OA de manos es menos evidente. El riesgo de efectos adversos precoces con el uso de CS IA es muy bajo. Sin embargo, los CS IA parece que producen efectos secundarios sobre el cartílago articular dependientes del tiempo y dosis. La tasa de infección después de una artroplastia de cadera no aumenta con las infiltraciones intrarticulares, siempre que pase suficiente tiempo entre la infiltración y la artroplastia (al menos 3-6 meses).En pacientes con OA de rodilla, el ácido hialurónico intrarticular (AH IA) se ha mostrado eficaz en el control del dolor a medio plazo (5-13 semanas) que se puede mantener a largo plazo (26 semanas) con resultados funcionales menos evidentes. La eficacia del AH en el control del dolor y la funcionalidad en los pacientes con OA de cadera y manos es menos evidente. Los efectos secundarios del AH son locales, generalmente leves y transitorios. No está bien establecido si son más frecuentes con AH de alto peso molecular, AH de origen aviar o con repetidas inyecciones.Las infiltraciones guiadas por imagen, en particular con ecografía, pueden mejorar la fiabilidad de la ubicación de la infiltración de CS o AH, sobre todo en cadera.(AU)
ntra-articular steroids (IA CS) are frequently used for the treatment of pain in patients with osteoarthritis (OA) of both the knee and the hip, especially in the early stages, with a rapid onset of action providing shortterm pain relief (1-6 weeks). IA CS do not clinically or significantly improve joint function of the knees or hips (stiffness, distance walked, or joint mobility) or quality of life. The efficacy of IA CS in hand OA is less evident. The risk of early adverse effects with the use of IA corticosteroids is very low. However, IA CS appear to have time- and dose-dependent side effects on articular cartilage. The infection rate after hip replacement does not increase with intra-articular injections, as long as there is enough time between the injection and the replacement (at least 3-6 months).In patients with knee OA, intra-articular hyaluronic acid (IA HA) has been shown to be effective in controlling pain in the medium term (5-13 weeks) that can be maintained until the long term (26 weeks) with less obvious functional results. The efficacy of HA in pain control and functionality in patients with hip and hand OA is less evident. The side effects of HA are local, generally mild and transitory. It is not well established if they are more frequent with HA of high molecular weight, HA of avian origin or repeated injections.Image-guided injections, particularly with ultrasound, can improve the reliability of the CS or HA injection location, especially in the hip.(AU)

The expectations from any future disease-modifying treatment for knee osteoarthritis (KOA) are extremely high as it has to impact the joint as a whole leading to favorable alterations of diverse tissues and functions. In this light, targeting the knee only from the inside may not be biologically justified for the management of a whole joint disease such as KOA. Our hypothesis to test is whether any injectable therapeutic intervention alone can lead to disease modification of KOA which is viewed in the complexity of the modern concept of osteoarthritis (OA) as a whole joint disease. Therefore, we aimed at analyzing the intraarticular route to the KOA patient in an attempt to unveil its "biological" constraints. A comprehensive search through databases was carried out using specific keywords to add objectivity to the main messages. The literature analysis has shown that "cutting-edge" intraarticular therapies may offer a key to non-invasive symptomatic relief. Changing the course of KOA, however, may necessitate a multimodal approach towards the knee joint including a combination of intraarticular injections with interventions on multiple levels. Importantly, our understanding of OA has evolved redefining the concept of the disease, being in interaction with the human body as a whole. Any future conservative disease-modifying treatment of KOA should aim at a multimodal, holistic approach towards the knee joint including but not limited only to intraarticular injections. A combination with other interventions should be further researched.

Study Objectiveâ :â the incidence of postoperative nausea and vomiting (PONV) following single-injection intraarticular anesthesia was compared to that following continuous epidural anesthesia. Designâ :â Prospective, double-blind, randomized study. Settingâ :â University-affiliated teaching hospital. Patientsâ :â Forty-eight patients finally participated in this study, and each group contained twenty-four patients. Interventionsâ :â Patients scheduled to undergo lower limb surgery under general anesthesia were randomly allocated into two groups, to receive either single-injection intraarticular or continuous epidural anesthesia for postoperative analgesia. Measurementsâ :â The incidence and severity of PONV, complete response rates (i.e., no vomiting or rescue antiemetic use), and pain scores were recorded 2, 24, and 48 h postoperatively. Main resultsâ :â No significant differences between groups were observed in the incidence and severity of PONV, rescue antiemetic use, or complete response rate at any of the time points, but only the use of rescue analgesics was significantly less in continuous epidural anesthesia group during the 2-24h postoperative period (P=0.04). Conclusionâ :â While the use of single-injection intraarticular anesthesia following lower limb surgery did not prevent PONV more than continuous epidural anesthesia in this study, the intraarticular technique still provides greater simplicity, safety, and cost-effectiveness.

PURPOSE: The aim of the study is to evaluate the effect of platelet-rich plasma (PRP) injection on temporomandibular joint (TMJ) cartilage and subchondral bone healing. MATERIALS AND METHODS: Sixteen New Zealand rabbits were divided into two groups, including single PRP and multiple PRP injection groups. Sodium mono-iodoacetate (MIA) was injected bilaterally into the TMJ of all rabbits to create osteoarthritis (OA). PRP was injected once into the right TMJ in the single PRP group and was injected three times (once a week) into the right TMJ in the multiple injection group 4 weeks after injection of MIA. At the time of each PRP injection, isotonic NaCl solution was injected into the left TMJ in the control groups. All animals were sacrificed 30 days after the first PRP injection. RESULTS: As a result of the histological evaluation, there was no statistically significant difference in cartilage and subchondral bone regeneration between the groups (p > 0.05). CONCLUSIONS: Although there was no statistically significant difference between PRP and control groups, it was seen that improvement were better in PRP groups. According to the Results of our study, it seems that different methods should be tried to investigate the efficacy of PRP on the TMJ healing.

BACKGROUND: Arthroscopic meniscus surgery can lead to pain at various levels. In this study, we aimed to compare, in patients undergoing arthroscopic meniscectomy under spinal anesthesia, the efficacy of the combination of magnesium sulfate and dexmedetomidine with local anesthetics administered intraarticularly for postoperative pain management Methods: This prospective, randomized, controlled, double-blind study comprised of 52 patients who were randomly assigned into two groups depending on the combination injected intraarticularly at the end of the procedure: bupivacaine and dexmedetomidine (group D) or bupivacaine and magnesium sulfate (group M). Perioperative data, postoperative visual analog scale (VAS) scores, and total analgesic consumption were recorded. CLINICAL TRIAL REGISTRATION: NCT03479216 Results: No statistically significant differences were found in mobilization times, rescue analgesic times, and non-steroidal anti-inflammatory consumption. The maximum mean VAS values at rest and during movement in group D were measured at the 6th hour while in group M peaked at the 8th hour. CONCLUSION: Both intraarticular dexmedetomidine and magnesium sulfate, in combination with bupivacaine, have similar effects on reducing postoperative pain in arthroscopic knee surgery. HIPPOKRATIA 2019, 23(2): 51-57.
RESUMO
BACKGROUND: The intraarticular (IA) injection has become popular for the management of the osteoarthritic knee without an effusion. The success rate of IA injection would be better if it was able to be visually confirmed. We hypothesized that an anterolateral approach, which targets the synovial membrane of the lateral condyle using ultrasound, would provide an equivalent alternative to the anterolateral approach, targeting the synovial membrane of the medial condyle for IA injection of the knee. METHODS: A total of 96 knees with osteoarthritis were randomized placed into the two groups, which were group I (anterolateral approach to the medial condyle) and group II (anterolateral approach to the lateral condyle). The primary outcome was to compare the success rate of the two methods of IA injection. The required length of the needle for injection was also measured and compared. Pain intensity was assessed using the Numeric Rating Scale in order to evaluate the success of injection. RESULTS: There were no significant differences in the success rate between both groups. The success rate of group I and group II were 87.8% (95%, CI 78.7-97.0) and 91.5% (95%, CI 83.6-99.5), respectively (P = 0.549). The needle depth was 5.0 ± 0.8 (3.0 to 6.1 cm) in group I, and 3.0 ± 0.8 (1.5 to 5 cm) in group II (P < 0.001). CONCLUSIONS: The anterolateral approach to the lateral femoral condyle, using ultrasound, is an alternative method to the approach targeting the medial femoral condyle, using shorter needle.
RESUMO
OBJECTIVE: Intraarticular corticosteroid (IAC) injections are often used to treat temporomandibular joint (TMJ) arthritis associated with juvenile idiopathic arthritis (JIA). One potential complication of IA therapy is heterotopic bone formation (HBF). The purpose of our study was to evaluate risk factors for HBF development in children with JIA who received IA therapy for TMJ arthritis. METHODS: This was a retrospective study of children with JIA who had received ≥ 1 IAC injection into the TMJ. Survival regression analysis was performed to identify risk factors for the development of HBF. RESULTS: There were 238 children included, of whom 33 (14%) developed HBF. No cases of HBF were diagnosed prior to the initial injection. Univariate analysis revealed that the risk factors for development of HBF were the total number of injections received into the TMJ and age at diagnosis of JIA, while the length of time from diagnosis of JIA to the first injection was inversely associated with the risk of HBF formation. The total number of injections was no longer significant following adjusted survival models. Children with HBF had increased physical examination evidence of acute or chronic changes, namely decreased maximal incisal opening and increased likelihood of jaw deviation. CONCLUSION: HBF within the TMJ is relatively common in patients with JIA receiving IAC injections for TMJ arthritis. Future prospective studies are required to delineate the risks posed by the injections themselves as opposed to the underlying disease activity, as well as to evaluate alternative forms of local therapy to the TMJ.

PATHOGENESIS: Osteoarthritis of the shoulder is characterized by a progressive degenerative process, which is based on chronic inflammation with intra-articular release of different cytokines and proteolytic enzymes. The main predisposing factors are a history of trauma or surgery, as well as chronic overuse or instability of the glenohumeral joint. Affected patients especially suffer from impaired joint function and pain, which are often associated with cognitive and psychosocial restrictions. DIAGNOSTICS: Possible co-pathologies have to be evaluated carefully both clinically and radiologically as they must be taken into account in the therapeutic procedure. If arthroplasty of the shoulder is planned, a pre-operative CT scan is mandatory in order to evaluate the bone stock of the glenoid, which has a decisive influence on the choice of implant. TREATMENT: Conservative treatment options are oral pain medication, physical therapy, and intra-articular injections, whereby, in comparison to corticosteroids, hyaluronic acid seems to be advantageous especially with respect to the duration of a positive clinical effect.
