Association between clinical parameters and size of three-dimensionally reconstructed anatomical abnormalities in patients with lateral epicondylitis: a cross-sectional study.

BACKGROUND: The association of the severity of clinical symptoms and level of functional performance with the degree of magnetic resonance imaging abnormalities in patients with lateral epicondylitis has not been fully elucidated. This study aimed to investigate the association between the degree of anatomical abnormalities by evaluating three-dimensional magnetic resonance imaging models of the common extensor tendon and clinical parameters in patients with lateral epicondylitis. MATERIALS AND METHODS: A total of 61 patients (24 men and 37 women) with lateral epicondylitis were included in this study. 3-Tesla magnetic resonance imaging was performed for all patients, and clinical parameters, including pain visual analog scale score, Quick Disabilities of Arm, Shoulder and Hand questionnaire score, elbow range of motion, and demographic factors, were evaluated. The proportion of lesion volume of common extensor tendon was adopted for three-dimensional model analysis. To determine the factors associated with clinical parameters, univariate, and multivariate linear regression analyses were performed. RESULTS: The proportion of lesion volume of common extensor tendon was not associated with clinical parameters. Gender and muscle edema were independently associated with pain visual analog scale scores. However, demographic factors and magnetic resonance imaging abnormalities were not associated with the Quick Disabilities of Arm, Shoulder, and Hand questionnaire score or elbow range of motion. CONCLUSIONS: The three-dimensional volumetric lesion size of common extensor tendon was not associated with clinical symptoms and functional performance in patients with lateral epicondylitis. The clinical parameters of lateral epicondylitis may be influenced by several factors.

Study on the effect of extra capsular arthroscopy plus analgesic tincture in the treatment of external humeral epicondylitis.

External humeral epicondylitis (EHE) is an inflammation and pain of the lateral tendons of the elbow with poor clinical efficacy. In this study, we aim to observe the effect of extra capsular arthroscopy (ECA) plus Traditional Chinese medicine (TCM) analgesic tincture in the treatment of EHE. A retrospective analysis was performed on the follow-up data of 58 patients with intractable EHE treated by ECA plus TCM analgesic tincture over 2 years from January 2017 to October 2018. All patients were followed up during the operation, with a mean follow-up duration of 17.6 months. There were no complications such as infection, nerve injury, wound nonunion and joint stiffness. The postoperative and pronation angles were statistically different from preoperative. The visual analogue scale (VAS) score during rest and movement of the elbow joint after operation was significantly different from that before operation. Postoperative Mayo elbow joint function score was significantly different from preoperative. Postoperative elbow joint function and brachial and shoulder dysfunction scores were statistically significant compared with those before surgery. Postoperative elbow joint function and brachial and shoulder dysfunction scores were statistically significant compared with those before surgery. The satisfaction rate of patients was 100%, with 52 cases of completely satisfied, 6 cases of basically satisfied and no dissatisfied cases. The curative effect of external capsular arthroscopy plus analgesic tincture in the treatment of external humeral epicondylitis was promising, which was worthy of clinical promotion.

Arthroscopic lateral capsule resection is enough for the management of lateral epicondylitis.

PURPOSE: Controversy exists with regards to the etiology and treatment of lateral epicondylitis and the role of the lateral capsule in this pathology. The aim of this study was to compare arthroscopic lateral capsule resection with or without extensor carpi radialis brevis (ECRB) tendon debridement for treatment of lateral epicondylitis. METHODS: This is a retrospective study of 38 patients who underwent arthroscopic surgery for LE with two different techniques: Eighteen patients were treated with arthroscopic lateral capsular resection (LCR) + ECRB debridement and 20 patients were treated with arthroscopic LCR alone, without ECRB debridement. Both groups were assessed with Quick Disabilities of the Arm, Shoulder and Hand (QDASH) score for function and Visual Analog Scale (VAS) score for pain. RESULTS: Quick DASH scores were 12 [Formula: see text] 5 and 13 [Formula: see text] 4 at Groups 1 and 2, respectively, without any statistically significant difference. VAS pain scores were 15 [Formula: see text] 2 for both groups. VAS function scores were 85 [Formula: see text] 22 and 86 [Formula: see text] 18 at Groups 1 and 2 respectively. Sick leave periods in terms of weeks were 7 [Formula: see text] 5 and 7 [Formula: see text] 4 at Groups 1 and 2, respectively. There was no statistically significant difference in outcome of the two groups compared in terms of VAS pain, function scores, failure (re-operation) rates and sick leave period at the end of final follow-up. CONCLUSION: Both arthroscopic LCR alone and Arthroscopic LCR with ECRB debridement for the management of refractory LE provide significant improvement in pain and function. Isolated Arthroscopic LCR could be a sufficient surgical treatment for refractory LE. Thus, ECRB debridement or release may not be necessary in every case. LEVEL OF EVIDENCE: IV.

Effect of autologous adipose-derived mesenchymal stem cell therapy in combination with autologous platelet-rich plasma in the treatment of elbow tendinopathy.

Tendinopathy is a common condition of both the athletic and general population and can be associated with significant pain and disability. The ability of mesenchymal stem cells (MSCs) to differentiate along a mesodermal cell lineage, including tenocytes, and secrete various bioactive regenerative and anti-inflammatory molecules has seen them considered as a future reparative therapy for tendinopathy. Preclinical trials with MSCs have shown promising positive functional and structural outcomes in several connective tissue related conditions. A 52-year-old male professional masters golfer presents with a clinical history of common extensor origin tendinopathy of the elbow. Subsequent formal ultrasound showed evidence of a large intrasubstance tear. The patient underwent intratendinous autologous adipose-derived MSC therapy in combination with autologous platelet-rich plasma. Following treatment, the patient reported progressive improvement as measured by the validated Numeric Pain Rating Scale and Patient-Rated Tennis Elbow Evaluation score. Repeat imaging showed successful regeneration of tendon-like tissue.

Efficacy of Extracorporeal Shock Wave Therapy for Lateral Epicondylitis: A Systematic Review and Meta-Analysis.

BACKGROUND: Lateral epicondylitis (LE) is a common elbow problem. Extracorporeal shock wave therapy (ESWT) was widely used in the treatment of LE and has been shown to relieve the pain and functional impairment (loss of grip strength) caused by tennis elbow. However, the evidence with regard to whether ESWT has better clinical efficacy over other method is not clear. The aim of the study was to compare the effectiveness of ESWT with other techniques in the treatment of LE. METHODS: Literature searches of PubMed, OVID, Embase, Cochrane Library, and Web of Science were searched up to 30th June, 2019. Only RCTs comparing ESWT with other methods for LE were included. Data collection and extraction, quality assessment, and data analyses were performed according to the Cochrane standards. RESULTS: A total of 13 articles with 1035 patients were included. Of which, 501 underwent ESWT and 534 underwent other methods. The result of meta-analysis showed that pooled VAS (P = 0.0004) and grip strength (P < 0.00001) were better in the ESWT group. CONCLUSION: Based on the existing clinical evidence, extracorporeal shock wave therapy can effectively relieve the pain and functional impairment (loss of grip strength) caused by tennis elbow, with better overall safety than several other methods. However, owing to the limited quality and quantity of the included studies, more high-quality RCTs are needed to support the trend towards better functional outcomes with ESWT.

PRP versus steroids in a deadlock for efficacy: long-term stability versus short-term intensity-results from a randomised trial.

PURPOSE: A popular choice for lateral epicondylitis (LE), corticosteroid injections have been associated with prominent side effects, which has led to the conception of modalities like platelet-rich plasma (PRP). This randomised trial aimed to evaluate and compare the 6-week, 3-month and 1-year outcomes with PRP and corticosteroid injections in LE. We hypothesised that PRP would prove more effective in relieving pain and improving function. METHODS: At the sports medicine unit of our tertiary care teaching centre, 80 patients with LE were randomised into either receiving PRP (group A) or corticosteroids (group B) injections. Pre-injection visual analogue scale (VAS), disabilities of the arm, shoulder and hand (DASH) score, Mayo elbow performance score (MEPS) and grip strength score (GSS) were recorded. Common extensor origins were identified and infiltrated with 3 ml of either PRP or corticosteroid (triamcinolone in 2% xylocaine) using a peppering technique. Follow-up scores and extent of pain relief were recorded and compared. RESULTS: At 6 weeks, there were greater improvements in group B versus A in mean VAS (13.8 vs. 44.5; p < 0.001), DASH (64.2 vs. 53.3; p < 0.001), MEPS (88.0 vs. 74.5; p = 0.004) and GSS (89.3 vs. 73.4; p = 0.039). These scores showed a reversed pattern at 3 months when group A outcomes superseded group B (VAS p = 0.002; DASH p < 0.001; MEPS p = 0.002; GSS p = 0.045). At 1-year follow-up, group A continued to enjoy better pain relief and function (VAS p = 0.024; DASH p < 0.001; MEPS p = 0.009; GSS p = 0.028). CONCLUSIONS: Albeit corticosteroid injections show good short-term results at 6 weeks, patients receiving PRP injections fare better at 3 and 12 months.

Comparison of platelet rich plasma and corticosteroids in the management of lateral epicondylitis: A meta-analysis of randomized controlled trials.

OBJECTIVE: To compare the clinical efficacy of platelet-rich plasma (PRP) injections with that of corticosteroids in patients with lateral epicondylitis (LE). METHODS: We searched for relevant studies on the comparison of PRP and corticosteroids in the management of lateral epicondylitis in electronic databases, including PubMed, Embase, Ovid, Cochrane Library, Web of Science, Wan Fang and China National Knowledge Internet, up to March 2019. The outcomes were pain score, elbow joint function and adverse effects after local injection. For continuous data, the weighted mean difference (WMD) and 95% confidence intervals (CIs) was used. Risk difference (RD) with a 95% CI were calculated for dichotomous outcomes. Cochrane Collaboration's tool was used to assess the risk of bias. The data were collected and input into the STATA software. RESULTS: A total of seven randomized controlled trials (RCTs) involving 515 patients were finally included in our study. The present meta-analysis indicated that PRP injection yielded statistically significant superior in pain scores and elbow joint function at a 6-month follow up compared with local corticosteroid injection. No significant difference was identified between two groups regarding the post-injection adverse events. CONCLUSION: Local PRP injections was associated with superior outcomes for reducing pain and improving elbow joint function compared with local corticosteroids treatment for LE at a follow-up of 6 months.

Photobiomodulation Therapy Versus Extracorporeal Shock Wave Therapy in the Treatment of Lateral Epicondylitis.

Objective: To compare the effects of photobiomodulation therapy (PBMT) and extracorporeal shock wave therapy (ESWT) on lateral epicondylitis (LE). Background: Although several authors have investigated the effects of PBMT and ESWT on LE, only one study to date has compared ESWT with PBMT. Ours is also the first study assessing patient satisfaction levels and quality of life in addition to comparing the two methods. Methods: Forty-three patients were randomly divided into two groups: 23 (mean age: 48.2 ± 9.4; 17 female, 6 male) were included in the PBMT group and 20 (mean age: 48.0 ± 9.9; 15 female, 5 male) in the ESWT group. PBMT was applied three times a week for 4 weeks, and ESWT once a week for 4 weeks. Stretching and eccentric strengthening exercises were also given to both groups as a home program. The Mayo Elbow Performance Score and disabilities of the arm, shoulder, and hand (DASH) were used for evaluating upper extremity functions. Pain intensity was evaluated using a visual analog scale (VAS), and muscle strengths were also assessed using a hand-held dynamometer. The 12-Item Short Form (SF-12) Survey Physical and Mental Component Scales were used to evaluate quality of life, and the global rating of change scale to evaluate patient satisfaction. Patients were assessed before treatment and at 12-week follow-up. Results: Improvements for elbow extension and shoulder flexion strength and for VAS movement were observed only in the PBMT group, whereas improvement of handgrip strength was present in both groups (p < 0.05). However, handgrip strength was superior in the PBMT group than in the ESWT group (p = 0.02). Conclusions: Both PBMT and ESWT are useful and can be used in the treatment of LE.

Comparison of scapular position and upper extremity muscle strength in patients with and without lateral epicondylalgia: a case-control study.

BACKGROUND: The symptoms of lateral epicondylalgia (LE) can be persistent, and recurrence is frequent. Recurrence can be related to proximal segment impairment of the kinetic chain. Knowledge of any relation in the kinetic chain in LE may help treatment. We aimed to investigate scapular position and upper extremity muscle strength in patients with LE and to compare them with controls. METHODS: The study enrolled 51 patients with LE and 51 age-matched controls. We assessed scapular position asymmetry using the lateral scapular slide test and measured the strength of the upper trapezius (UT), middle trapezius (MT), lower trapezius, and serratus anterior muscles in addition to shoulder abduction, external rotation, and internal rotation and grip strength. RESULTS: The percentage of participants with scapular asymmetry was greater in the patients than in the controls (P = .005). The involved side regarding shoulder external rotation among the patients was significantly weaker than in the controls (P = .016, P = .009). The involved side of the LE patients was significantly weaker than the uninvolved side in terms of shoulder abduction, external rotation, and internal rotation (P = .013, P = .048, P = .013). The UT/MT ratio on the nondominant side of the controls was significantly greater than that on the involved side of the LE patients (P = .016). CONCLUSION: Upper extremity muscle strength, grip strength, UT/MT ratio, and scapular position are affected in patients with LE. In addition to the elbow, focusing on the upper segments is essential in the management of LE.

Arthroscopic chronic tennis elbow surgery preserves elbow proprioception.

STUDY DESIGN: Retrospective cohort study. INTRODUCTION: A new method of accurately assessing the compromised elbow's proprioception was developed for this postsurgical population using information from previous neurophysiologic proprioception studies of healthy elbows. HYPOTHESIS: This retrospective cohort study investigated the patterns and the degree of proprioceptive impairment and recovery following arthroscopic surgery for chronic lateral epicondylitis. MATERIAL AND METHODS: Participants had undergone arthroscopic elbow surgery two years prior to this study (n=15). Healthy, non-injured volunteers with similar demographics (n=15) served as controls. Both groups were evaluated using quantitative measures of joint position sense for proprioceptive functioning. In order to obtain the most accurate proprioceptive measurements, interindividual interaction and visual input biases were eliminated. Retrospective chart reviews were performed to compare qualitative self-reported measures of proprioceptive function in arthroscopic surgery patients before surgery and two years post-surgery. RESULTS: Active and passive joint repositioning outcome measurements were similar between groups (p>0.05). No significant differences were found among any angles except one: passive joint position sense at 120° of flexion (p<0.05). At this angle, the arthroscopy group showed greater deviation from target angles than the control group. The novel proprioceptive testing method we developed was found to be accurate and reliable. DISCUSSION: Outcomes of arthroscopic treatment of chronic lateral epicondylitis with no decortication yielded outcomes measure similar to those of healthy controls. The sole significant difference was at 120° flexion passive joint repositioning, with a higher negative angular deviation from the target point. We propose that our study results and specific proprioception method may have implications for improving accuracy of future elbow arthroscopy and proprioceptive recovery in this population. LEVEL OF EVIDENCE: II, low-powered prospective randomized trial.

Counterforce bracing of lateral epicondylitis: a prospective, randomized, double-blinded, placebo-controlled clinical trial.

BACKGROUND: Counterforce bracing is one of the common treatment modalities for tennis elbow. The objective of this study was to determine whether counterforce bracing offers any additional benefit over placebo bracing in the treatment of tennis elbow. METHODS: This prospective, randomized, double-blinded, placebo-controlled clinical trial investigated the use of counterforce bracing (n = 17) compared with placebo bracing (n = 14) in the management of acute tennis elbow. Outcome measures included patient-rated pain and functional outcomes, epicondyle tenderness, and strength at 6 months and long term. Follow-up occurred at 2, 6, 12, and 26 weeks, as well as long term (mean follow-up, 3 years). The study duration was 5 years. RESULTS: The 2 groups, counterforce and placebo, were similar in age, sex, hand dominance, and duration of symptoms. Both braces improved patient-rated pain frequency and severity (P < .01), difficulty with picking up objects and twisting motions, and overall elbow function (P < .001) at 6 months and 3 years. Both braces also improved lateral epicondyle tenderness, grip strength (P < .01), and modified ORI-TETS (Orthopaedic Research Institute-Tennis Elbow Testing System) force (P < .05) at 6 months. Significant intergroup differences were detected for frequency of pain at rest at 6 and 12 weeks (P < .05), level of pain at rest at 2 weeks (P < .001), and patient-rated overall elbow function at 26 weeks (P = .041). CONCLUSION: The counterforce brace provides significant reduction in the frequency and severity of pain in the short term (2-12 weeks), as well as overall elbow function at 26 weeks, compared with the placebo brace.

The Prognostic Value of Pain Sensitization in Patients With Lateral Epicondylitis.

PURPOSE: Pain sensitization is a contributing factor to conditions of chronic pain. The aim of this study was to evaluate the influence of pain sensitization on the prognosis of lateral epicondylitis (LE) treated by self-stretching exercises and the use of a counterforce brace. METHODS: We enrolled 131 patients who presented with isolated LE symptoms for less than 6 months. We initially measured pain sensitization by assessing patients' pressure pain thresholds (PPTs) in the contralateral middorsal forearm and administering a pain sensitization questionnaire (PSQ). For outcome assessments, we assessed the self-administered, patient-reported Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire at 6 and 12 months' follow-up. RESULTS: Initial PSQ scores correlated moderately with baseline DASH scores and slightly with symptom duration; PPTs correlated slightly with baseline DASH scores. After we accounted for confounding variables, patient-reported disability was associated with lower PPTs, higher PSQ scores, and manual labor at 6 months. These 3 factors accounted for 36% of variance in the DASH scores; however, at 12 months only the PSQ score was associated with higher DASH scores, accounting for 14% of variance. CONCLUSIONS: Pain sensitization during the early stages of LE correlated with initial symptom severity and duration and was associated with persistently increasing disability after 1 year of nonsurgical treatment. More research is needed to show whether early identification and treatment of pain sensitization will enhance LE treatment outcomes. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Utility of Prolotherapy for Upper Extremity Pathology.

Prolotherapy is a method of treatment of painful musculoskeletal conditions whereby a sclerosing agent is injected into an area of tendinosis or osteoarthritis to strengthen and repair painful connective tissue. It is a safe, effective, and relatively inexpensive nonsurgical treatment modality. This article provides a history of prolotherapy, discusses its proposed mechanisms of action, and provides a review of the existing literature on prolotherapy as a treatment for upper extremity pathologies, specifically, hand osteoarthritis, lateral epicondylitis, and rotator cuff disease.

First clinical experience with a new injectable recombinant human collagen scaffold combined with autologous platelet-rich plasma for the treatment of lateral epicondylar tendinopathy (tennis elbow).

BACKGROUND: Lateral epicondylitis is a tendinopathy of the common extensor origin at the elbow. When traditional conservative treatment fails, more effective therapies are needed. Vergenix Soft Tissue Repair (STR) Matrix (CollPlant Ltd., Ness-Ziona, Israel) is an injectable gel composed of cross-linked bioengineered recombinant human type I collagen combined with autologous platelet-rich plasma (STR/PRP). The complex forms a collagen-fibrin matrix that promotes cell migration and tissue repair. Based on positive outcomes from preclinical trials, this study is the first clinical trial of STR/PRP on tendinopathy. We hypothesized that STR/PRP would be a safe and effective treatment for lateral epicondylar tendinopathy. METHODS: Patients with chronic lateral epicondylitis underwent treatment with STR/PRP. Outcome assessment included grip strength, functional disability, and changes in sonographic tendon appearance for up to 6 months after treatment. RESULTS: The study enrolled 40 patients. No systemic or local severe adverse events were reported. Clinical evaluation revealed an improvement in the mean Patient-Rated Tennis Elbow Evaluation score from 64.8 before treatment and showed a 59% reduction at 6 months. The 12-Item Short-Form Health Survey questionnaire showed improvement from a mean score of 30.7 to 37.7 at the final follow-up. Grip strength increased from 28.8 kg at baseline to 36.8 kg at 6 months. Improvements in sonographic tendon appearance were evident among 68% of patients. CONCLUSION: STR/PRP is a safe treatment that effectively induces clinically significant improvements in elbow symptoms and general well-being as well as objective measures of strength and imaging of the common extensor tendon within 6 months of treatment of elbow tendinopathy recalcitrant to standard treatments.

The immediate sensorimotor effects of elbow orthoses in patients with lateral elbow tendinopathy: a prospective crossover study.

BACKGROUND: Counterforce orthoses are used to manage lateral elbow tendinopathy, and their effectiveness in improving motor function has been documented. Little is known about the impact of bracing on sensory function. The objective of this study was to investigate the immediate effectiveness of 2 counterforce orthoses in improving the sensorimotor abilities of the hand in patients with lateral elbow tendinopathy. METHODS: In this crossover, randomized controlled trial, elbow proprioception, pain severity, pain-free grip strength, and finger dexterity were measured in 50 participants with a diagnosis of lateral elbow tendinopathy. Outcomes were measured in 3 randomized conditions (no brace, forearm band, or elbow sleeve). Data were analyzed using 1-way repeated-measures analysis of variance for each outcome measure. RESULTS: Better scores were observed with the forearm band, as compared with no orthosis, for multiple outcomes including joint position reproduction score at 70° of elbow flexion (P = .006), pain (P < .001), grip strength (P = .01), and dexterity (P < .001). The elbow sleeve yielded better scores than no orthosis for the following outcomes: joint position reproduction score at 110° (P < .001), pain (P < .001), and grip strength (P = .012). No statistically significant difference was found between the orthoses' effects on pain reduction and grip strength (P > .05). The forearm band showed better scores on joint position reproduction at 70° compared with the elbow sleeve (P = .006), whereas the elbow sleeve showed better scores at 110° (P < .001). CONCLUSION: Our results support the mechanisms occurring with the use of either of the described orthotic interventions. Future randomized trials with longer-term outcomes that include sensorimotor mechanisms might enhance our understanding of the comparative effectiveness.

Prospective randomized controlled trial in the treatment of lateral epicondylitis with a new dynamic wrist orthosis.

BACKGROUND: In the treatment of lateral epicondylitis (LE), the role of a new dynamic wrist orthosis is unclear. PATIENTS AND METHODS: Patients suffering from a LE longer than 3 months were multicentrically and prospectively randomized into a physiotherapeutic group (PT group) and in a physiotherapy group plus wrist orthosis (PT + O group). Physiotherapy consisted of daily eccentric strengthening exercises under initial professional supervision. Inclusion criteria were a Placzek score greater than 4. Exclusion criteria were previous surgery, rheumatic arthritis, elbow instability, radicular symptoms, higher-grade extensor tendon rupture, or cervical osteoarthritis. The clinical evaluation was performed after 12 weeks and 12 months. The Patient-Rated Tennis Elbow Evaluation (PRTEE) scale, Placzek Score, the pain rating (VAS), range of motion and the Subjective Elbow Score were evaluated. RESULTS: Of the initially 61 patients, 31 were followed up after 12 weeks and 22 after 12 months. Twenty-nine patients (43%) were male, the mean age was 46, and 44 patients (66%) had the right elbow involved. At 12 weeks, there was a pain reduction on the VAS in both groups (PT + O: 6.5-3.7 [p = .001]; PT: 4.7-4.1 [p = .468]), albeit it was only significant for the PT + O group. At 12 months, reduction was significant in both groups (PT + O: 1.1 [p = .000]; PT: 1.3 [p = .000]). The painless maximum hand strength in kg improved in both groups significant after 3 and 12 months. The Placzek score was reduced from 8.25 to 3.5 [p = .001] after 12 weeks for the PT + O group and from 8.1 to 3.8 [p = .000] in the PT group, as well as after 12 months in the PT + O group to 0 [p = .000] and in the PT group to 2.0 [p = .000]. The PRTEE improved in both groups after 12 weeks (PT + O: 52.8--31.3 [p = .002]; PT: 48.6-37.6 [p = .185]) and 12 months (PT + O: 16.15 [p = .000]; PT: 16.6 [p = .000]), although the reduction at 12 weeks was not significant for the PT group. CONCLUSION: The elbow orthosis appears to accelerate the healing process with respect to the PRTEE and pain on the VAS (12 weeks follow-up), although there is an adjustment after 12 months in both groups and a significant improvement of symptoms is achieved in all endpoints.

Comparison of the Clinical Outcomes of Open Surgery Versus Arthroscopic Surgery for Chronic Refractory Lateral Epicondylitis of the Elbow.

Numerous surgical options have been introduced for the treatment of chronic refractory lateral epicondylitis of the elbow, but it remains unclear which option is superior. The clinical outcomes of an open surgery group and an arthroscopic surgery group were evaluated, and the results of the 2 procedures were compared. From among patients with lateral epicondylitis refractory to 6 months of conservative treatment, 68 patients satisfying study criteria were recruited. Open surgery was performed in 34 cases (group 1), and arthroscopic surgery was performed in 34 cases (group 2). Compared with preoperatively, the 2 groups had significantly improved values for grip strength, range of motion, and Disabilities of the Arm, Shoulder and Hand score at 12 months postoperatively. Group 1 had significantly greater improvements in grip strength and visual analog scale pain score compared with group 2 (P=.048 vs P=.006). Group 2 had significantly greater (P=.045) improvement in pronation compared with group 1. Group 2 returned to work sooner than group 1. On the questionnaire regarding satisfaction with surgery 24 months postoperatively, 4 patients (12%) in group 2 reported dissatisfaction compared with no patients in group 1. Open surgery and arthroscopic surgery both yielded good clinical results. Nonetheless, for patients requiring muscle strength or having severe pain at work, open surgery would be more effective.

A Comparison of Radiofrequency-Based Microtenotomy and Arthroscopic Release of the Extensor Carpi Radialis Brevis Tendon in Recalcitrant Lateral Epicondylitis: A Prospective Randomized Controlled Study.

PURPOSE: To compare the clinical effects of radiofrequency (RF)-based microtenotomy and arthroscopic release of the extensor carpi radialis brevis (ECRB) tendon in patients with recalcitrant lateral epicondylitis through a prospective randomized controlled study. METHODS: A total of 46 patients were randomly assigned to receive arthroscopic release (group A, 24 patients) or RF-based microtenotomy (group B, 22 patients). The visual analog scale (VAS) score for pain, flexion-extension arc, operation time, Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH), Mayo Elbow Performance Score (MEPS), and grip power of groups A and B were compared during the recovery phases for up to 2 postoperative years. RESULTS: Both groups showed statistically significant functional improvement compared with their preoperative grip strength and DASH, VAS, and MEPS scores at 2 years after surgery (P < .05). There were no differences in postoperative pain relief or functional restoration between the 2 groups during the recovery phases, however the mean operation time for group B (41.4 ± 5.2 minutes) was significantly shorter than that for group A (15.6 ± 3.6 minutes, P < .001). In group B, 1 patient underwent revision surgery due to postoperative ECRB rupture, and 1 patient in group A underwent open release for persistent postoperative discomfort. CONCLUSIONS: RF-based microtenotomy for treating recalcitrant lateral epicondylitis provided clinical outcomes comparable with those from arthroscopic release of ECRB tendon during the recovery phase. RF-based microtenotomy is considered as one of the surgical procedures for treating recalcitrant lateral epicondylitis, with the advantages of reliable elbow functional restoration and significantly shorter operation time. LEVEL OF EVIDENCE: Level I, prospective randomized trial.

Does Kinesiotaping improve pain and functionality in patients with newly diagnosed lateral epicondylitis?

PURPOSE: This study aimed to compare the short-term effects of kinesiotaping and extracorporeal shock wave therapy (ESWT) along with physiotherapy on pain, functionality, and grip strength in patients with newly diagnosed lateral epicondylitis undergoing rehabilitation. METHODS: Forty-five voluntary patients (mean age 48 years) were randomly assigned to three groups. Patients in all groups received physiotherapy consisting of a cold pack and transcutaneous electrical nerve stimulation five times per week for a total of 15 sessions and a home exercise programme including stretching and eccentric strength exercises. In the second group, patients received kinesiotaping 5 days a week for 3 weeks. In the third group, ESWT was applied three times for 3 weeks. Patients were assessed by visual analogue scale for pain intensity, pain-free grip strength using a hand dynamometer, Cyriax Resisted Muscle Test, and Patient-Rated Tennis Elbow Evaluation Scale. All measurements were collected at baseline and after treatment. RESULTS: There were no significant differences in the demographic characteristics of the patients in all groups at baseline. Intra-group analysis revealed that pain intensity decreased, whereas maximum grip strength and functionality increased in all groups at the end of the treatment (p < 0.05). Inter-group analysis revealed that the kinesiotaping group yielded better results in decreasing pain intensity than the other groups (p < 0.05). The kinesiotaping group (p < 0.001) and ESWT group (p = 0.002) yielded better results in improving functionality than the physiotherapy group. There were significant differences in recovering pain-free grip strength in the kinesiotaping group (p < 0.05). CONCLUSION: Kinesiotaping was found to be effective for decreasing pain intensity, recovering grip strength, and improving functionality in patients with lateral epicondylitis undergoing rehabilitation. LEVEL OF EVIDENCE: Therapeutic study, Level II.
