Lateral Epicondylalgia (LE) represents one of the most common injuries of the upper limb. It is necessary to find effective treatments that reduce pain and increase functionality. To determine the effects of an integrated intervention of Pulsed Negative Pressure Myofascial Vacuum Therapy (VT), Percutaneous Electrolysis (PE) and eccentric exercise (EE) in the treatment of LE compared versus Manual Therapy soft tissue mobilization (MT) and Ultrasound therapy (US) and EE. Single-blind randomized controlled trial. Forty participants, with unilateral LE, were randomly divided into two groups: VT + PE + EE group (n = 20) and MT + US + EE group (n = 20). The VT + PE + EE group received one weekly session for four weeks and a regimen of EE daily at-home, and the MT + US + EE group received 10 sessions over a period of two weeks and a regimen of EE daily at-home. Numerical pain rating scale (NPRS), range of motion (ROM) pressure pain threshold (PPT) and function (PRTEE questionnaire) were measured before treatment, at the end of treatment, and at one- and three-month follow-ups. The statistically significant improvements were found post-treatment, favoring the VT + PE group in pain intensity (p < 0.001; ES = 0.408), PRTEE-S Pain (p = 0.001; ES = 0.377), PRTEE-S Specific function (p = 0.004; ES = 0.306) and PRTEE-S Total (p = 0.001; ES = 0.355). The VT + PE + EE treatment showed greater effectiveness than the MT + US + EE treatment at immediate post-treatment, as well as at the one-month and three-months follow-up. VT and PE added to an EE program could be an effective treatment for pain, ROM, PPT, and function in patients with LE. • Electrolysis and Myofascial Vacuum Therapy in epicondylalgia. • Electrolysis, negative pressure & eccentric exercises: effective in epicondylalgia. • Electrolysis+negative pressure+exercise more effective than manual therapy+ultrasound.

Background: Lateral and medial elbow tendinopathies are common soft tissue disorders affecting 1–3% of the general population, causing significant pain and functional impairment in the elbow and upper limb. While often associated with overuse and repetitive strain, their exact etiology, including potential associations with prior injuries in adjacent joints, remains unclear. This preliminary study aims to explore the distribution of lateral and medial elbow tendinopathies and investigate the occurrence of previous lesions in adjacent joints among diagnosed individuals, providing foundational insights for future research. Methods: A multicenter cross-sectional observational study was conducted involving 90 subjects diagnosed with lateral and/or medial elbow tendinopathy. The data collection occurred during the initial consultations, including demographic information, clinical assessments, and history of prior injuries in adjacent joints. Results: Among the sample, 44.4% reported prior injuries to adjacent joints in the affected upper limb, with 45.6% of these injuries identified as musculotendinous in nature. The analysis also showed that the type of elbow tendinopathy was significantly associated with sex (p = 0.01) and occupational origin (p = 0.022). Conclusions: While a notable percentage of the subjects reported prior musculoskeletal injuries in the same limb, the study's geographic limitations and reliance on self-reported data introduce potential recall bias. These preliminary findings suggest a possible relationship between prior adjacent joint injuries and elbow tendinopathy. Further research with larger sample sizes and more rigorous study design is needed to confirm these observations and explore the underlying mechanisms. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study was to assess the effects of adding electrical dry needling and thrust manipulation into a multimodal program of exercise, mobilization, and ultrasound in patients with lateral elbow tendinopathy. Design: Randomized, single-blinded, multicenter, parallel-group trial. Setting: Thirteen outpatient physical therapy clinics in nine different US states. Participants: One hundred and forty-three participants (n = 143) with lateral elbow tendinopathy were randomized. Intervention: Cervical spine manipulation, extremity manipulation, and percutaneous tendon electrical dry needling plus multimodal physical therapy (n = 73) or multimodal physical therapy (n = 70) alone. Main measures: The primary outcome was elbow pain intensity and disability as measured by the Patient-Rated Tennis Elbow Evaluation at baseline, 1 week, 4 weeks, and 3 months. Secondary outcomes included the Numeric Pain Rating Scale, Tennis Elbow Functional Scale, Global Rating of Change, and medication intake. Results: The 2 × 4 analysis of covariance demonstrated that individuals with lateral elbow tendinopathy receiving electrical dry needling and thrust manipulation plus multimodal physical therapy experienced significantly greater improvements in disability (Patient-Rated Tennis Elbow Evaluation: F = 19.675; P < 0.001), elbow pain intensity (Numeric Pain Rating Scale: F = 22.769; P < 0.001), and function (Tennis Elbow Function Scale: F = 13.269; P < 0.001) than those receiving multimodal physical therapy alone at 3 months. The between-group effect size was large for pain and disability (Patient-Rated Tennis Elbow Evaluation: standardized mean difference = 1.13; 95% confidence interval: 0.78, 1.48) in favor of the electrical dry needling and thrust manipulation group. Conclusions: The inclusion of percutaneous tendon electrical dry needling and thrust manipulation into a multimodal program of exercise, mobilization and ultrasound was more effective than multimodal physical therapy alone in individuals with lateral elbow tendinopathy.

Introduction: Medial epicondylitis, often called golfer's elbow, involves pain on the inner side of the elbow. It usually results from repetitive strain on the tendons that connect the forearm muscles to the medial epicondyle. While commonly linked to golfing, it can affect people engaged in various activities requiring repetitive wrist flexion and gripping. Purpose of work: This paper aims to provide a comprehensive overview of the pathogenesis, imaging characteristics, and treatment strategies for medial epicondylitis. State of knowledge: Medial epicondylitis can be worsened by activities that require forceful gripping, such as golfing or weightlifting [1][2]. The condition has been extensively studied and is well-documented in the scientific literature. Various treatments are available, including conservative methods like rest, physical therapy, and injections, as well as surgical interventions for persistent cases. Material and methods: This review draws upon an in-depth analysis of current scientific literature, including recent publications in prominent medical journals and relevant research studies. To identify pertinent scientific publications and research studies, comprehensive searches were conducted on widely recognized academic databases, such as PubMed and Google Scholar. Summary: Medial epicondylitis, also known as "golfer's elbow," is characterized by pain and tenderness over the bony prominence on the inner side of the elbow. It often results from repetitive strain or overuse of the muscles that flex the wrist and pronate the forearm [3]. Diagnostic imaging, such as X-rays and MRI, can help evaluate this condition [1][4]. Treatment typically involves a combination of conservative approaches, including rest, physical therapy, and anti-inflammatory medications, as well as more invasive options like corticosteroid injections or surgery for persistent cases.

Introduction Tennis Elbow, known also as Lateral Epicondylitis (LE) is a very common overuse injury affecting not only tennis players. Mainly, it causes pain, weakness in grip strength and difficulties with daily activities. Most patients are successfully treated with non-surgical methods but some of them eventually require surgical intervention. Aim of study The objective of this study is to evaluate both surgical and non-surgical treatment methods for Tennis Elbow and seeks to introduce doctors and patients to the assets and downsides associated with them. State of Knowledge Tennis Elbow occurs in 1-3% of adults, most likely when frequently performing repeated movements of flexion and extension of the elbow. At the early stages inflammation is present, after that the vascular hyperplasia and active fibroblasts occur. Most common risk factors are manual labour, ipsilateral rotator cuff tear, ipsilateral Carpal Tunnel Syndrome (CTS), female sex, dominant-side involvement, and hypertriglyceridemia. Summary (Conclusion) There is a wide range of available conservative treatment methods for Lateral Epicondylitis including physical therapy, various injections, and medication. They should be considered as the first line treatment showing high success rate for mild and moderate cases. Surgical methods have high success rates as well though they are considered more invasive and performed only on chronic patients. Best approach ought to be carefully selected for each patient based on severity of symptoms and patient needs.

Background: This radiological study aims to assess the prevalence of lateral elbow pathology in an asymptomatic population using 3.0T magnetic resonance imaging (MRI). Methods: Bilateral elbow MRI was undertaken in 30 asymptomatic volunteers. Exclusion criteria included elbow pain within 3 months, elbow trauma or previous diagnosis of lateral epicondylar tendinopathy. Baseline patient-reported outcome measures were recorded along with age and body mass index (BMI). Two musculoskeletal radiologists independently graded the degree of abnormality at the common extensor tendon. Results: Thirty volunteers were categorised according to age; 35–44 (n = 10), 45–54 (n = 11), and 55–65 (n = 9) with a 1:1 male-to-female ratio. Radiological evidence of tendon abnormality was found in 37% of volunteers. The proportion with abnormal findings increased with age; 35–44 (10%), 45–54 (36%), 55–65 (67%) and BMI; 18–24.9 (23%), 25–29.9 (43%), > 30 (67%). Changes were generally 'mild' or 'moderate', with a single volunteer showing 'severe' pathology. Kappa for the radiographic agreement was 0.91 (0.83–0.98). Discussion: This study has demonstrated MRI findings suggestive of pathology at the common extensor tendon to be prevalent in an asymptomatic population, increasing with age and BMI. This draws into question the diagnostic and prognostic value of MRI imaging in lateral epicondylar tendinopathy, especially in older patients. [ABSTRACT FROM AUTHOR]

Biceps brachii distal tendon injury is rare, 2.55–5.35 per 100,000. This nosological form did not have a gender modality and was previously found mainly in middle-aged men (46.3 y.o.). By 2022, this injury “rejuvenated” and began to occur more often, covering the categories of juniors and young athletes, whose professional activities have expanded significantly with the advent of new power disciplines, contact sports and popularization of bodybuilding. The authors note the negative impact of smoking and the use of anabolic steroids, statins and obesity on the incidence of these lesions. The maximum supination force in this type of injury is reduced by an average of 40 %, and the maximum flexion force is reduced by an average of 20 %. Considering the significance of functional disorders not only of the elbow joint, but also of motor patterns of the entire upper limb girdle for professional athletes, sports-organized people and people involved in the physical aspects of labor, surgical treatment is recommended. Nonsurgical treatment can be aimed at suppressing edema and inflammation, limiting early movements in the elbow joint and increasing secondary muscle tension, and it is suitable for patients with low functional demand, poor compliance and high risks of both surgical treatment and anesthesia care. That is, the choice of treatment tactics is still based, in addition to anatomical changes and on the “subjective” patient data, his/her needs for physical activity and requires an algorithmic approach in order to avoid both known complications and confidently predict a positive result during the prehospital period. Based on ten years of clinical and practical experience adjusted by widely available scientific periodicals, we have developed a scheme that is understandable to every specialist in the field of traumatology, orthopedics or sports medicine, and is applicable regardless of the medical institution level. For the first time, this scheme was published in this work.

The review article explores recent advances in the surgical treatment of elbow pain, a common ailment that can significantly impair daily functioning. With a surge in elbow-related conditions such as tennis elbow, osteoarthritis, and nerve compression disorders, the necessity for surgical approaches has become paramount. This article provides an overview of the cutting-edge procedures now available, including minimally invasive arthroscopic surgery. These modern methods have been shown to significantly reduce recovery times and improve overall patient outcomes. The combination of surgical management and targeted rehabilitation ensures a comprehensive and personalized treatment plan for patients with various elbow pathologies. This article aims to shed light on these recent surgical interventions and their potential for advancing the management of elbow pain, emphasizing the ongoing trend toward precision, efficiency, and patient-centered care.

Pain originating from the elbow can be due to issues affecting the joint itself or the structures surrounding it. These structures include the medial and lateral epicondyles, associated ligaments, the origins of wrist flexor and extensor muscles, the olecranon bursa, the distal biceps tendon, and the radial and ulnar nerves. Pain that appears to originate from a different location may actually be referred pain, potentially stemming from the neck (cervical radiculopathy) or the shoulder. Among complaints related to the elbow, lateral elbow pain is the most frequently reported. This pain could originate from the lateral epicondyle, the radiohumeral joint, or it could be referred pain from other areas. Medial elbow pain is the second most common complaint, often resulting from issues with the medial epicondyle or the ulnar nerve as it travels through the cubital tunnel. The biceps tendon is frequently the cause of anterior elbow pain. Patients who report swelling in the elbow are often experiencing olecranon bursitis. These conditions can often be effectively managed through conservative treatment. The aim of this article is to provide a structured approach to addressing patients with elbow pain, by detailing the common causes of such discomfort and exploring effective nonsurgical treatment options.

Upper limb tennis injuries are primarily chronic, resulting from repetitive overuse. We developed a wearable device which simultaneously measures risk factors (grip strength, forearm muscle activity, and vibrational data) associated with elbow tendinopathy development resulting from tennis players' technique. We tested the device on experienced (n = 18) and recreational (n = 22) tennis players hitting forehand cross-court at both flat and topspin spin levels under realistic playing conditions. Using statistical parametric mapping analysis, our results showed that all players showed a similar level of grip strength at impact, regardless of spin level, and the grip strength at impact did not influence the percentage of impact shock transfer to the wrist and elbow. Experienced players hitting with topspin exhibited the highest ball spin rotation, low-to-high swing path brushing action, and shock transfer to the wrist and elbow compared to the results obtained while hitting the ball flat, or when compared to the results obtained from recreational players. Recreational players exhibited significantly higher extensor activity during most of the follow through phase compared to the experienced players for both spin levels, potentially putting them at greater risk for developing lateral elbow tendinopathy. We successfully demonstrated that wearable technologies can be used to measure risk factors associated with elbow injury development in tennis players under realistic playing conditions.

Abstract Background Lateral epicondylitis is one of the most common upper extremity problems presented to orthopedic surgeons. Despite a rapid and accurate arrival at a diagnosis by clinical examination, there exists no consensus classification for this condition, which hampers clinical approaches for treatment of the disease based on its severity. Thus, the aim of this study was to propose and valiadate a new magnetic resonance imaging (MRI) classification of lateral epicondylitis, staging by tendinosis, the degree of thickness tears of the common extensor tendon (CET) and bone bruise lesion. Method MRI assessment of the elbow of 75 patients (57 women and 18 men; mean age:51.4 years (range,34–73) from Jan 2014 to Jan 2021 who were diagnosed with lateral epicondylitis were included in the study. MR images were reviewed retrospectively by two independent upper extremities orthopedists and one musculoskeletal radiologist. Inter- and intra-observer reliabilities for the classification were calculated using kappa statistics for the analysis of interrater agreement. Correlation between the stage of the disease and the duration of symptom before MRI was calculated using Kruskal–wallis test. Results Various degrees of CET lesions were demonstrated in this population (Stage I-17, IIA-7, IIB-22 and III-29). Intra-observer agreements of MRI staging were substantial to satisfactory. Inter-observer agreements were moderate to substantial. There was no significant correlation between the disease stage and the patient age or the duration of symptom before MRI. Conclusion Our MRI classification has emerged as one of the most reliable methods to define stages of chronic lateral epicondylitis. At the end, we have suggeted a clearer direction for understanding the disease pathology as well as an appropriate management protocol for each stage of the disease in line with the recent body of literature.

Background: The efficacy of eccentric exercise self-performed by the patient has not been proved in the treatment of lateral elbow tendinopathy (LET). The aim of this study was to compare the effects of a programme of eccentric exercises applied by a physiotherapist to patients with LET through a structured manual programme compared to its self-performance, guided by an illustrated brochure. Method: A single-blind, pilot, randomised, controlled trial was conducted. Twenty patients were randomised. The intervention group carried out eccentric exercises applied directly by a physiotherapist (10 sessions). The control group carried out eccentric exercises that were self-performed by the patient (10 sessions). Both groups received simulated ultrasounds. Pain (visual analogue scale (VAS)), function (DASH questionnaire) and satisfaction (with a Likert scale) were measured at the beginning of the intervention, immediately after the intervention and 3 months after the intervention. Results: The mean age was 53.17 and 54.25 years old. The experimental group presented a greater tendency to improve function (DASH −15.91) and reduce pain (VAS −2.88) compared to the control group, although these differences were not significant (p > 0.05). Conclusion: Eccentric exercise, both performed by the physiotherapist and self-performed by the patient, improved function and pain in the patients with LET. [ABSTRACT FROM AUTHOR]

Purpose: Individuals with Lateral Epicondyle Tendinopathy (LET) commonly experience gripping deficits, which are marked by pain and altered motor control of the forearm extensors and flexors. Although delayed activation of the anconeus muscle during rapid wrist extension has been observed in LET, its role during gripping is not well understood. This study aimed to investigate anconeus activation and its relation to forearm muscle activity during gripping in individuals with LET., Methods: Eleven participants with LET and 11 healthy, age-, sex-, and limb-matched controls performed steady-state isometric gripping at 15% and 30% of their maximum voluntary contraction (MVC). Surface electromyography was recorded from anconeus and six forearm muscles. Standard clinical assessments for LET were conducted to evaluate the severity of the condition., Results: Participants with LET exhibited increased relative activation of anconeus compared the forearm flexors, but not with the extensors, during both 15% and 30% MVC gripping. Additionally, the LET group demonstrated an increased coactivation ratio between anconeus and extensor carpi radialis brevis, as well as the flexor digitorum superficialis (FDS) during 15% MVC. At 30% MVC, this increased coactivation was observed between anconeus and all three flexors (FDS, flexor carpi radialis, flexor carpi ulnaris). Lower anconeus activation was associated with greater LET-related disability, while higher anconeus activation was associated with increased anconeus tenderness., Conclusion: This study presents novel evidence of an adaptive motor pattern in LET, characterized by increased relative activation and coactivation of the anconeus muscle depending on grip force. Signs of maladaptive motor patterns emerge when grip force becomes painful. These findings enhance our understanding of anconeus dysfunction in LET and the gripping deficits that accompany it, offering new insights into potential management strategies for this condition., Level of Evidence: Basic Science Study; Kinesiology., (Copyright © 2024.

Elbow tendinopathy injuries are very common in tennis players. One of the commonly accepted theories describing the development of elbow tendinopathy in tennis is based on stiffness of the forearm skeletal muscle units and their repetitive overuse in the forehand stroke. Our objective was to use a novel microcontroller based wearable device to compare the influence of different forehand spin levels (flat, topspin and lob) and ball exit speed on forearm muscle activity in the potential onset of elbow tendinopathy in experienced adult tennis players. Peak normalised extensor carpi radialis (ECR) and flexor carpi radialis (FCR) muscle activity corresponding to each forehand shot and ball exit speed were determined and analysed. For the ECR shots (flat = 121, topspin = 272 and lob = 273) by 8 players, Kruskal-Wallis test (p < 0.001) and Post-Hoc tests revealed a significant difference between the flat and topspin spin levels (p < 0.01) and flat and lob spin levels (p < 0.001). For the FCR shots (flat = 125, topspin = 301 and lob = 303) by 9 players, Kruskal-Wallis test showed no significant difference between the three spin levels. For the corresponding ball speed, the Kruskal-Wallis (p < 0.001) and subsequent Post-Hoc (p < 0.001) showed that flat hits had the significantly highest ball speed followed by topspin then lob accordingly for both muscles included shots. Our results suggest that coaches could consider recommending players to hit forehands with topspin in order to potentially reduce the risk of developing lateral elbow tendinopathy.

Background: Lateral epicondylitis (LE) is a highly prevalent musculoskeletal disorder in workers, often associated with physically demanding work. Knowledge of work‐relatedness of LE is crucial to develop appropriate preventive measures. This study investigates the prospective association between work‐related physical risk factors and LE. Methods: A systematic literature review was conducted in MedLine using PubMed from January 1, 2010 until February 16, 2021. Published reports were included if: (1) LE was clinically assessed, (2) exposure to work‐related physical risk factors was assessed, and (3) associations between LE and work‐related physical risk factors were reported in prospective studies. Quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation. Results: In total, 318 workers with LE from a population of 5036 workers in five studies were included. Meta‐analyses revealed high‐quality evidence for associations between LE and a Strain Index (SI) score >5.1 (odds ratio [OR]: 1.75, 95% confidence interval (CI): 1.11–2.78) and moderate‐quality evidence for forearm rotation >4 h/day or forearm rotation ≥45° for ≥45% time (OR: 1.85, 95% CI: 1.10–3.10). Gripping, flexion and extension of the wrist, and repetitive movements showed no significant associations with LE. Conclusion: High‐quality evidence was found indicating that a higher SI increased the risk of LE. Moderate‐quality evidence was found for an association between forearm rotation and LE. No associations were found between other physical risk factors and LE. Primary preventive interventions should focus on a reduction of the SI and of high forearm rotation in work.

Although elbow tendinopathy is the one of common diseases causing elbow pain, ideal nonoperative treatment to provide long-term satisfaction has not been introduced. Recently, there is significant interest in biological treatment to facilitate the healing environment and tissue proliferation in elbow tendinopathy. Biological agents such as platelet-rich plasma (PRP) or stem cells are likely to be established as one of the nonoperative treatment methods that can have long-term therapeutic effects in the future, given their theoretical basis. Despite many previous studies using biological agents such as PRP and stem cells in the elbow, its beneficial effect on elbow tendinopathy is controversial. Thus, the purpose of this review is to provide an evidence-based summary of the biologic agent for treating elbow tendinopathy and to identify areas where further research is warranted.

Purpose: The lateral elbow musculature conveys a dynamic valgus moment to the elbow, increasing joint stability. Muscular or tendinous lesions to the anterior half of the common extensor origin (CEO) may provoke a deficiency in the elbow dynamic stabilizers, regardless of their traumatic, degenerative, or iatrogenic aetiology. Furthermore, a role for the radial band of the lateral collateral ligament (R-LCL) has been postulated in the aetiology of lateral elbow pain. This study aimed to evaluate the effects of sequential lateral releases with dynamic ultrasound, evaluating its capability to detect lesions of the CEO and of the R-LCL. Methods: Ultrasound investigation of the lateral compartment of the elbow was performed on nine cadaveric specimens with a 10 MHz linear probe in basal conditions, after the release of the anterior half of the CEO and after complete R-LCL release. The lateral joint line widening (λ) was the primary outcome parameter, measured as the linear distance between the humeral and radial articular surfaces. Results: The release of the anterior half of the CEO significantly increased λ by 200% compared to the starting position (p = 0.0008) and the previously loaded position (p = 0.0015). Conversely, further release of the R-LCL caused only a marginal, non-significant increase in λ. Conclusions: Ultrasound evaluation can detect changes related to tendon tears or muscular avulsions of the CEO and can depict lateral elbow compartmental patholaxity by assessing articular space widening while scanning under dynamic stress. However, it cannot reliably define if the R-LCL is injured. Iatrogenic damage to the CEO should be carefully avoided, since it causes a massive increase in compartmental laxity.

Objectives: To evaluate the ability of shear wave elastography (SWE) in diagnosing medial epicondylitis and to compare the diagnostic performance of SWE with that of grey-scale ultrasound (GSU) and strain elastography (SE).Methods: GSU, SE, and SWE were performed on 61 elbows of 54 patients from March 2018 to April 2019. An experienced radiologist evaluated the GSU findings (swelling, cortical irregularity, hypoechogenicity, calcification, and tear), colour Doppler findings (hyperaemia), SE findings (strain ratio [SR]), and SWE findings (stiffness and shear wave velocity [SWV]). Participants were divided in two groups: patients with clinically diagnosed medial epicondylitis and patients without medial elbow pain. Findings from the two groups were compared, and the receiver operating characteristic (ROC) curves were calculated for significant features.Results: Of the 54 patients, 25 patients with 28 imaged elbows were clinically diagnosed with medial epicondylitis and 29 patients with 33 imaged elbows had no medial elbow pain. Cortical irregularity, hypoechogenicity, calcification, hyperaemia, SR, stiffness, and SWV were significantly different between the two groups. The areas under the ROC curves were 0.838 for hypoechogenicity, 0.948 for SR, 0.999 for stiffness, and 0.999 for SWV. The diagnostic performances of SR, stiffness, and SWV were significantly superior compared to that of hypoechogenicity. However, there were no significant differences among SR, stiffness, and SWV.Conclusions: SWE can obtain both stiffness and SWV, which are valuable diagnostic tools in the diagnosis of medial epicondylitis. The diagnostic performance of SWE and SE is similar in detecting medial epicondylitis.Key Points: • Shear wave elastography providing stiffness and shear wave velocity showed excellent performance in the diagnosis of medial epicondylitis. • There was no significant difference in the ability of SE and SWE for diagnosing medial epicondylitis.

Abstract Objectives To determine the efficacy of platelet-rich plasma (PRP) compared to lidocaine as a tenotomy adjuvant for people with elbow tendinopathy. Methods Our study was a parallel-group, double-blind, randomized trial involving 71 patients with recalcitrant elbow tendinopathy who received two sessions of ultrasound-guided tenotomy with either PRP or lidocaine in a tertiary public hospital. The primary end point was the percentage of patients with an improvement exceeding 25% reduction in disability (Spanish version of the Disabilities of the Arm, Shoulder and Hand questionnaires–DASH-E) at 6 and 12 months; the secondary outcome was the percentage of patients exceeding 25% reduction in pain (VAS-P). Results There was no evidence of significant differences in the proportion of patients who experienced clinically relevant improvements. After 6 months, 18 patients (78.59%) in the lidocaine group and 19 patients (73.08%) in the PRP group showed improved function above 25% (unadjusted odds ratio, 0.90; 95% confidence interval [CI], 0.90 (0.17 to 4.60)); 21 patients (72.21%) in the lidocaine group versus 22 patients (84.62%) in the PRP group achieved more than 25% pain reduction (unadjusted odds ratio, 0.48; 95% CI, 0.10 to 2.37). After 12 months, 17 patients (70.83%) in the lidocaine group versus 19 patients (76%) in the PRP group had improved function (unadjusted odds ratio, 0.71; 95% CI, 0.13 to 3.84), and 19 patients (76%) in the lidocaine group versus 20 patients (90.91%) in the PRP group had improved pain above 25% (unadjusted odds ratio, 0.35; 95% CI, 0.06 to 2.51). Hypercholesterolemia and baseline vascularization influenced outcomes. There were no differences between groups in the adjusted odds ratios. Conclusion PRP results in similar improvements to those obtained with lidocaine. Selecting patients according to their pretreatment status can improve treatment efficacy.

Background: Elbow instability, particularly posterolateral rotatory instability (PLRI), has been reported in patients with refractory lateral epicondylitis (LE). However, evidence of diagnostic approach and surgical outcomes is lacking. Purpose: To identify (1) the risk factors, clinical and radiologic-diagnostic characteristics, and (2) the treatment options and clinical outcome of LE with PLRI. Study design: Systematic review. Methods: We searched the PubMed, Ovid/MEDLINE, Cochrane Library, Google Scholar, Scopus, and EMBASE databases using keywords as well as Medical Subject Headings terms and Emtree using "(lateral epicondylitis OR tennis elbow) AND (instability OR posterolateral rotatory instability)" for English-language studies. We conducted a systematic review using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Results: In total, 8 articles comprising 6 level 4 and 2 level 3 studies were identified, including 249 patients (254 elbows). The main triggering factor was heavy labor activity (74/172; 43%). A total of 184 patients (73.9%) received either single (4/184; 2.2%) or multiple (180/184; 97.8%) steroid injections. Clinically, instability was always accompanied by pain in 9% of study individuals. Magnetic resonance imaging (MRI) revealed that radial collateral ligament (RCL) and lateral ulnar collateral ligament (LUCL) lesions were most common (18/79; 23%). The most common surgical procedure performed was arthroscopic RCL plication (62/120; 52%) followed by LUCL reconstruction (30/120; 25%). A ligament patholaxity sign was shown intraoperatively for 64% (44/69). Clinical outcomes ranged from good to excellent in all studies. The most common residual symptom was limited range of motion (11/18; 61%). Conclusion: Instability can coexist and may be associated with refractory LE. The risk factors of instability associated with refractory LE are heavy labor and multiple steroid injections. A systematic approach to identify the clinical and MRI presentation of the condition followed by examination under anesthesia are necessary for affirmative diagnosis, as independent presentations may be misleading.

Objectives: To evaluate the evidence of an association between occupational and non-occupational exposure to biomechanical risk factors and lateral elbow tendinopathy, medial elbow tendinopathy, and olecranon bursitis. Methods: We carried out a systematic review of the literature. We searched MEDLINE (up to November 2019) and checked the reference lists of relevant articles/ reviews. We aimed to include studies where (a) the diagnosis was based on physical examination (symptoms plus clinical signs) and imaging data (if any); and (b) the exposure was evaluated with video analysis and/or direct measurements. A quality assessment of the included studies was performed along with an evaluation of the level of evidence of a causal relationship. Results: We included four studies in the qualitative synthesis: two prospective cohorts and two cross-sectional studies. All the included studies investigated “lateral/medial epicondylitis”, albeit the diagnosis was not supported by imaging techniques. Two cohort studies suggested that a combination of biomechanical risk factors for wrist/forearm is associated with increased risk of “lateral epicondylitis”. This association was not observed in the two included cross-sectional studies. The cohort studies suggested that a Strain Index score higher than 5 or 6.1 could double the risk of “lateral epicondylitis”. No association with increased risk of “medial epicondylitis” was observed. Conclusions: There is limited evidence of a causal relationship between occupational exposure to biomechanical risk factors and lateral elbow tendinopathy. For medial elbow tendinopathy, the evidence is insufficient to support this causal relationship. No studies on olecranon bursitis and biomechanical overload were identified. [ABSTRACT FROM AUTHOR]

BACKGROUND: Lateral elbow tendinopathy (LET), commonly known as tennis elbow, is a prevalent work-related upper extremity musculoskeletal disorder. Medical practitioners and hand therapists manage LET with commonly available clinic-based treatments, despite no sound evidence to suggest long-term relief and functional restoration for workers with LET. Workplace-based rehabilitation is effective for injured workers with other health conditions, but no studies have investigated this rehabilitation approach in the management of LET. OBJECTIVES: (i) Identify, compare, and contrast Australian hand therapists' and medical practitioners' perceptions about the effectiveness of common treatments for LET, and (ii) obtain their views towards a hand therapist delivered workplace-based education approach. METHODS: In this cross-sectional study, 38 medical practitioners from Western Australia and 104 hand therapists around Australia completed online surveys. Independent t-tests were used to identify between-group differences in responses. RESULTS: Despite some between-group differences regarding the perceived effectiveness of common LET treatments, both groups believed education about LET pathology, activity modification, postures, and workplace recommendations were most effective. Most medical practitioners (81%) and hand therapists (71%) believed workplace-based education delivered by a hand therapist would be beneficial for patients with acute and chronic LET. CONCLUSION: Australian hand therapists and medical practitioners believed educational approaches were the most important component in the management of LET, and supported workplace-based educational interventions provided by hand therapists in the management of LET.
