Lateral epicondylitis (tennis elbow): nonoperative, open, or arthroscopic treatment?

Clinical and Ultrasonographic Effectiveness of Two Different Splints Used for the Treatment of Lateral Epicondylitis: A Prospective Randomized Controlled Study

OBJECTIVE

This study compares the clinical and ultrasonographic efficacy of 2 splint types, the lateral epicondylitis band (LEB) and the wrist extensor splint (WES), for treatment of lateral epicondylitis (LE).

DESIGN

Randomized controlled single-blind trial.

SETTING

Outpatient clinic.

PARTICIPANTS

159 participants diagnosed with unilateral LE based on clinical and ultrasonographic findings, and 2-12 weeks from symptom onset, were included (N=159).

INTERVENTIONS

One group received joint-protection education-only (wait-and-see), while the other 2 groups were fit with splints: one the LEB and the other the WES. Both splint groups received joint-protection education.

MAIN OUTCOME MEASURES

The primary outcome measure was the Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire. Secondary outcome measures were the Visual Analog Scale (VAS) for pain, hand grip strength by dynamometry, algometric measurements, patient satisfaction, and selected ultrasonographic parameters (maximum tendon thickness measurements (MTTM) in the capitellar-radiocapitellar region and total ultrasonography scale score [TUSS]). All outcomes were assessed at baseline, 3-weeks, and 6-weeks post intervention initiation.

RESULTS

Participants' mean age was 46.85±8.63 years. Of the participants, 40.88% (n=65) were male and 59.12% (n=94) were female. The baseline median (1Q-3Q) values of PRTEE-total scores were 58.5 (51-68) for the LEB, 63.5 (56.25-70.25) for the WES and 57 (48-68) for the education-only groups. At 6-weeks, the PRTEE-total scores had decreased by 44 points for those randomized to the LEB, 46 points to the WES and 7 points in the education-only groups(P<.001). While the LEB and WES approaches were superior to the wait-and-see approach in algometric measurements, VAS, and PRTEE scores (P<.05), no significant changes were found in MTTM and TUSS values. The LEB group was superior to the WES group in hand grip strength and patient satisfaction (P<.05).

CONCLUSION

Using either splint for 6 weeks can be considered effective for the relief of pain and increased functionality in persons with subacute LE, although the LEB had a more positive effect on grip strength and patient satisfaction than the WES.

Comparison of the efficiency of peloidotherapy and extracorporeal shock wave therapies in patients diagnosed with lateral epicondylitis: a prospective, randomized, controlled study

Various treatment methods are used in the management of lateral epicondylitis (LE); however, there is no universally accepted standard treatment approach. The aim of this study is to compare the effects of peloidotherapy and extracorporeal shock wave therapy (ESWT) on pain, functional status, and quality of life in the treatment of LE. The study was designed as a hospital-based, prospective randomized controlled trial. Ninety patients, with a mean age of 47.30±7.95 (range, 18 to 65 years), diagnosed with chronic (3 months) unilateral LE were included in the study. The patients were randomly divided into two groups. The peloidotherapy group received 15 sessions of peloid therapy for 3 weeks, 5 days a week, while the ESWT group received three sessions of ESWT (1.8 bar, 10.0 Hz, 2000 impulses) for 3 weeks, once a week. The patients were evaluated before treatment, at the end of the treatment, and one month after the treatment. The groups were compared in terms of pain, quality of life, functional status, and handgrip strength. At the end of the treatment and one-month follow-up, statistically significant improvements were observed in all parameters. This study is the first randomized trial comparing peloidotherapy to ESWT as an adjunct to exercise therapy in LE. Both ESWT and peloidotherapy, when added to exercise therapy, showed positive short-term effects on pain, quality of life, functional status, and handgrip strength in primary conservative treatment of chronic LE (p<0.001), and no superiority was found between them in terms of efficacy. Peloidotherapy or ESWT may be preferred in the treatment of lateral epicondylitis, depending on the patient's condition. Peloidotherapy appears to be more advantageous due to its lower side effects and painless nature. ClinicalTrials.gov ID: NCT04748406.

Comparison of the effectiveness of peloid therapy and kinesio taping in tennis elbow patients: a single-blind controlled study

This study aimed to compare the peloid therapy and kinesio tape treatments in chronic lateral epicondylitis. While home exercise program and cold application were applied to the control group, peloid therapy (5 days a week for 3 weeks at 45 °C for 30 min each day, a total of 15 treatment days) was applied in addition to the first group, and kinesio taping (6 treatment days 2 times a week) was applied to the second group. Patients were evaluated with visual analog scale (VAS), grip strength with Jamar hydraulic dynamometer, Arm, Shoulder, and Hand Disabilities (DASH), quality of life in Short Form-36 (SF-36), and Patient-Rated Forearm Evaluation Questionnaire (PRFEQ) was recorded before treatment, after treatment (third week), and 1 month after the end of treatment. In this study, 156 patients with chronic lateral epicondylitis were included. In the follow-up of the patients, there was a statistically significant improvement in the hand grip strength, DASH, PRFEQ, VAS, and SF-36 scores in the 1st month follow-up after the treatment compared to the pre-treatment control in all groups (p < 0.001). At the end of the treatment, the hand grip strength (p = 0.002), DASH (p < 0.001), PRFEQ pain (p < 0.001) and function (p = 0.007), SF-36 physical health (p = 0.002) scores were statistically significant in the peloid therapy group compared to the control group. At the 1st month after the end of treatment, hand grip strength, VAS, DASH, PRFEQ pain, function, daily activities, and SF-36 physical health scores (all of p < 0.001) were statistically significant in the peloid treatment group compared to the control group. Peloid treatment was found to be more effective than kinesio taping in SF-36 physical health (p = 0.007) and PRFEQ pain (p = 0.003) scores in the 1st month follow-up after treatment. Peloid therapy in addition to exercise seems more effective in chronic lateral epicondylitis. Randomized controlled long-term studies are needed.ClinicalTrials ID: NCT04687943.

Analgesic Effect of Extracorporeal Shock-Wave Therapy in Individuals with Lateral Epicondylitis: A Randomized Controlled Trial

This study was conducted to investigate the effect of extracorporeal shock-wave therapy (ESWT) on pain, grip strength, and upper-extremity function in lateral epicondylitis. A sample of 40 patients with LE (21 males) was randomly allocated to either the ESWT experimental (n = 20) or the conventional-physiotherapy control group (n = 20). All patients received five sessions during the treatment program. The outcome measures used were the Visual Analog Scale (VAS), the Taiwan version of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, and a dynamometer (maximal grip strength). Forty participants completed the study. Participants in both groups improved significantly after treatment in terms of VAS (pain reduced), maximal grip strength, and DASH scores. However, the pain was reduced and upper-extremity function and maximal grip strength were more significantly improved after ESWT in the experimental group. ESWT has a superior effect in reducing pain and improving upper-extremity function and grip strength in people with lateral epicondylitis. It seems that five sessions of ESWT are optimal to produce a significant difference. Further studies are strongly needed to verify our findings.

Hand-Grip Strength and Return to Heavy Manual Work at a Mean 5-Year Follow-up After Arthroscopic Release of Recalcitrant Lateral Epicondylitis

Background:

Lateral epicondylitis of the elbow is a common degenerative disorder in middle-aged patients. Surgery is reserved for patients who do not respond to nonoperative treatment.

Purpose:

To evaluate hand-grip strength and return to heavy manual activities in patients engaged in work requiring heavy lifting after arthroscopic release of refractory lateral epicondylitis.

Study Design:

Case series; Level of evidence, 4.

Methods:

The study included consecutive patients who underwent arthroscopic release of the extensor carpi radialis brevis tendon to treat recalcitrant lateral epicondylitis of the elbow, with a minimum 48-month follow-up. Functional outcome measures included assessment of hand-grip strength, visual analog scale for pain, and Mayo elbow performance score. The recorded measurements were compared at postoperative 1 and 6 months and the final assessment. Pre- and postoperative data were compared using the paired t test, and the various postoperative assessments were compared using 1-way analysis of variance.

Results:

A total of 22 patients (mean ± SD; age, 34.6 ± 5.9 years) with a mean follow-up of 60.5 ± 4.7 months were included in our study. There were highly significant improvements between preoperative and 1-month postoperative results regarding hand-grip strength (17.5 ± 4.1 kg to 34.4 ± 6.8 kg), visual analog scale score for pain (7.86 ± 1.2 to 1.8 ± 1.09), and Mayo score (57.1 ± 7.9 to 89.3 ± 4.9; P < .00001 for all). Significant improvements were found on all 3 functional measures between 1 and 6 months postoperatively (P ≤ .05 was statistically significant), and there were nonsignificant improvements on all measures from 6-month to final follow-up. The patients regained 96.4% of their hand strength as compared with the unaffected side and returned to their previous activities without reporting serious complications.

Conclusion:

Minimally invasive arthroscopic release of recalcitrant lateral epicondylitis of the elbow provided a satisfactory functional result, as shown by regaining of hand-grip strength in patients engaged in heavy manual occupations without significant morbidities.

A comparative study of the efficacy of ultrasonics and extracorporeal shock wave in the treatment of tennis elbow: a meta-analysis of randomized controlled trials

BACKGROUND

Tennis elbow or lateral epicondylitis is a common source of pain among craftsmen. Although it cannot be completely resolved, extracorporeal shock wave therapy (ESWT) and ultrasonics (US) have been found to be effective for tennis elbow as highlighted in previously published randomized controlled trials (RCTs) and reviews. However, the efficacy of these two therapies in treating tennis elbow is unknown. This meta-analysis compares the effectiveness of ESWT and US in relieving pain and restoring the functions of tennis elbow following tendinopathy.

METHODS

RCTs published in the PubMed, Embase, Cochrane Library, and SpringerLink databases comparing ESWT and US in treating tennis elbow were identified by a software and manual search. The risk of bias and clinical relevance of the included studies were assessed. Publication bias was explored using funnel plot and statistical tests (Egger's test and Begg's test). The major outcomes of the studies were analyzed using the Review Manager 5.3.

RESULTS

Five RCTs comprising five patients were included in the present meta-analysis. The results revealed a significantly lower VAS score of pain in the ESWT group (1 month: MD = 4.47, p = 0.0001; 3 months: MD = 20.32, p < 0.00001; and 6 months: MD = 4.32, p < 0.0001) compared to US. Besides, the grip strength was markedly higher 3 months after the intervention in ESWT (MD = 8.87, p < 0.00001) than in the US group. Although no significant difference was observed in the scores of the elbow function after 3 months of treatment (SMD = 1.51, p = 0.13), the subjective scores of elbow functions were found to be better in the ESWT group (SMD = 3.34; p = 0.0008) compared to the US group.

CONCLUSIONS

Although there was no significant difference in the elbow function evaluation scores between ESWT and US, the superiority of the ESWT group in the VAS of pain (both at 1 month, 3 months, and 6 months follow-ups) raised grip strength in ESWT group and the scores for subjective evaluation of efficacy indicated that ESWT offers more effective therapy for lateral epicondylitis than US therapy.

Comparison of an epicondylitis bandage with a wrist orthosis in patients with lateral epicondylitis

BACKGROUND:

Lateral epicondylitis is one of the most common causes of elbow pain. It is generally observed in people between the ages of 40 and 50 years, and the dominant extremity is more frequently affected. Various noninvasive methods are frequently used; however, studies investigating the effectiveness of the orthoses are limited and with controversial outcomes.

OBJECTIVE:

To investigate the effectiveness of a hand-wrist resting orthosis and an epicondylitis bandage in lateral epicondylitis.

STUDY DESIGN:

Randomized controlled trial.

METHODS:

In total, 82 patients diagnosed with unilateral lateral epicondylitis were enrolled into the study. Hand-wrist resting orthosis was applied to 45 patients and epicondylitis bandage was applied to 41 patients. Patients were evaluated before treatment and at 6 weeks after treatment with a Visual Analogue Scale; Disabilities of the Arm, Shoulder, and Hand questionnaire; the Short Form 36; and a determination of hand grasping force.

RESULTS:

Both groups were similar in terms of age, body mass index, gender, frequency of lateral epicondylitis on the dominant side, dominant extremity, and duration of complaints ( p > 0.05). A statistically significant recovery was detected in both groups between the pre-therapy values and the values at the sixth week in terms of Visual Analogue Scale scores; Disabilities of the Arm, Shoulder, and Hand questionnarie scores; hand grasping forces; and the Short Form 36 mental and physical component scores ( p < 0.05). However, there were no significant differences detected between the two therapy methods before the therapy and at the sixth week of treatment in all parameter values ( p > 0.05).

CONCLUSION:

Our results suggest that both epicondylitis bandage and hand-wrist resting orthosis are effective treatment options for lateral epicondylitis-induced pain, functional status, muscle strength, and quality of life. Furthermore, neither treatment option was superior to the other. Large, randomized studies are necessary for more clear statements.

CLINICAL RELEVANCE

Epicondylitis bandage and hand-wrist resting orthosis are equally effective treatment options for lateral epicondylitis-induced pain, functional status, muscle strength, and quality of life.

A randomized, double-blind sham-controlled trial on the efficacy of arthroscopic tennis elbow release for the management of chronic lateral epicondylitis

BACKGROUND

Tennis elbow is a common elbow pathology typically affecting middle-aged individuals that can lead to significant disability. Most cases resolve within 2 years of symptom onset, but a subset of patients will develop persistent symptoms despite appropriate conservative management. There are several surgical approaches used to treat chronic tennis elbow, with arthroscopic surgery becoming an increasingly popular approach to address this pathology in North America. This procedure involves the arthroscopic release of the extensor carpi radialis brevis tendon (ECRB) origin at the elbow. The potential benefit of arthroscopic treatment of this condition is improved patient outcomes and shorter recovery time following surgery. The results of this technique have been reported only in the context of case series, which have shown positive results. However, in order to justify its widespread use and growing popularity, a high level of evidence study is required. The purpose of this prospective, randomized sham-controlled trial is to determine whether arthroscopic tennis elbow release is effective at treating chronic lateral epicondylitis.

METHODS

We will conduct a prospective single center, double-blind, randomized sham-controlled parallel arm trial evaluating the efficacy of arthroscopic tennis elbow release in adult patients with symptoms for at least 6 months. Patients will undergo intraoperative randomization after diagnostic arthroscopy of the elbow to receive either ECRB release (through the creation of a lateral portal) or a sham lateral portal and no ECRB release. The primary outcome will be the Mayo Elbow Performance Score (MEPS) at 1 year follow-up. Secondary outcomes will be the abbreviated Disability of the Shoulder and Hand (DASH) score, American Shoulder and Elbow Surgeons elbow (ASES-e) score and grip strength at 3, 6, 12 and 24 months as well as return-to-work time, ability to return to full duty and adverse outcomes.

DISCUSSION

Results of this study will provide empirical high quality evidence to guide clinical decision-making in patients with chronic tennis elbow.

Ultrasound-guided, minimally invasive, percutaneous needle puncture treatment for tennis elbow

INTRODUCTION

This report evaluates the efficacy of percutaneous needle puncture under sonographic guidance in treating lateral epicondylitis (tennis-elbow).

METHODS

Ultrasound-guided percutaneous needle puncture was performed on 76 patients who presented with persistent elbow pain. Under a local anesthetic and sonographic guidance, a needle was advanced into the calcification foci and the calcifications were mechanically fragmented. This was followed by a local injection of 25 mg prednisone acetate and 1% lidocaine. If no calcification was found then multiple punctures were performed followed by local injection of 25 mg prednisone acetate and 1% lidocaine. A visual analog scale (VAS) was used to evaluate the degree of pain pre-and posttreatment at 1 week to 24 weeks. Elbow function improvement and degree of self-satisfaction were also evaluated.

RESULTS

Of the 76 patients, 55% were rated with excellent treatment outcome, 32% good, 11% average, and 3% poor. From 3 weeks posttreatment, VAS scores were significantly reduced compared with the pretreatment score (P<0.05) and continued to gradually decline up to 24 weeks posttreatment. Sonography demonstrated that the calcified lesions disappeared completely in 13% of the patients, were reduced in 61% of the patients, and did not change in 26% of the patients. Color Doppler flow signal used to assess hemodynamic changes showed a significant improvement after treatment in most patients.

CONCLUSION

Ultrasound-guided percutaneous needle puncture is an effective and minimally invasive treatment for tennis elbow. Sonography can be used to accurately identify the puncture location and monitor changes.
