Ultrasound-guided tenotomy improves physical function and decreases pain for tendinopathies of the elbow: a retrospective review

The Effects of Ultrasound-Guided Percutaneous Tenotomy on Patients' Pain and Satisfaction Levels

INTRODUCTION

Tendinopathy is a common pathology with numerous treatment options. Ultrasound-guided percutaneous tenotomy is a newer procedure to treat chronic tendinopathy. It reduces costs and risks compared to other treatments, such as open surgery and platelet-rich plasma (PRP) injections. The goal of percutaneous tenotomy is to induce an acute inflammatory response that recruits clotting and growth factors, induces bleeding, and transforms scar tissue and diseased tendons into a healing state.

METHODS

A tenotomy was performed in 57 patients for elbow epicondylitis (13), supraspinatus tendonitis (4), gluteal tendinopathy (34), and patellar tendinopathy (5). The survey was created and sent electronically to all 57 patients, yielding 46 respondents. Each patient was surveyed postoperatively to determine their pain levels on a numeric scale from 1 to 10 prior to and following the procedure. We also asked patients about their satisfaction with the procedure, whether they would recommend it to a friend, and how long it took them to recover completely.

RESULTS

Forty-six of 57 patients responded to the survey. The average healing time was 58 days, and no patients required further surgery. Pain scores significantly improved after tenotomies in the shoulder, elbow, and hip. About 74% of patients were completely satisfied with the procedure, and 80% received enough benefit to recommend it to a friend.

CONCLUSIONS

Ultrasonic tenotomy provides significant relief for tendinopathy in the shoulder, elbow, and hip for the majority of patients. The knee pain scores were not significantly reduced, likely due to the small sample size of four patients. Some patients did not experience complete relief and benefited from a PRP injection after tenotomy. Some patients did not benefit, likely due to additional pathology, arthritis, and referred pain. Some limitations to our study include the lack of a control group and each procedure was performed by the same physician, which limits its generalizability. The survey responses were subjective, and the sample size was variable between each body region. More high-quality research is needed to establish the efficacy of tenotomy between different tendons and compare it to other treatment methods.

Three-Month Complication Rate of Ultrasound-Guided Soft Tissue Surgical Procedures Across Six Sports Medicine Clinics

OBJECTIVES

To 1) determine the types and frequency of complications within 3 months following ultrasound-guided surgical procedures, and 2) identify any patient demographics, co-morbidities, or procedural characteristics that were associated with an increased risk of complications.

METHODS

A retrospective chart review was performed at six Sports Medicine clinics across the United States. The Clavien-Dindo classification was used to categorize procedural complications on a 5-point scale from 1, representing any deviation in post-procedure care without requiring pharmacological or invasive treatment to 5, representing death. Generalized Estimating Equations for binomial outcomes with a logit link were used to estimate the overall and procedure-specific 3-month complication rates.

RESULTS

Among 1902 patients, 8.1% (n = 154) had diabetes and 6.3% (n = 119) were current smokers. The analysis included 2,369 procedures, which were performed in either the upper extremity (44.1%, n = 1045) or lower extremity (55.2%, n = 1308) regions. The most common procedure was ultrasound-guided tenotomy (69.9%, n = 1655). Additional procedures included, trigger finger release (13.1%, n = 310), tendon scraping (8.0%, n = 189), carpal tunnel release (5.4%, n = 128), soft tissue release (2.1%, n = 50), and compartment fasciotomy (1.6%, n = 37). Overall, there was a complication rate of 1.2% (n = 29 complications; 95% CI: 0.8-1.7%). Individual procedures had complication rates that ranged from 0 to 2.7%. There were 13 Grade I complications in 13 patients, 12 Grade II complications in 10 patients, 4 Grade III complications in 4 patients, and 0 Grade IV or V complications. No associations between complication risk and any patient demographics (age, sex, BMI), co-morbidities (diabetes, smoker), or procedure characteristics (type, region) were identified.

CONCLUSION

This retrospective review provides an evidence-based estimate supporting the low level of risk associated with ultrasound-guided surgical procedures for patients from a variety of geographical settings who are seeking care at private and academic-affiliated clinics.

Percutaneous ultrasound-guided needle tenotomy for treatment of chronic tendinopathy and fasciopathy: a meta-analysis

OBJECTIVES

To systematically assess the efficacy of percutaneous ultrasound-guided needle tenotomy (PUNT) in the treatment of chronic tendinopathy and fasciopathy.

METHODS

A comprehensive literature search was performed with the following search terms: tendinopathy, tenotomy, needling, Tenex, fasciotomy, ultrasound-guided, and percutaneous. Inclusion criteria consisted of original studies evaluating pain or function improvement after PUNT. Meta-analyses investigating standard mean differences were performed to assess the pain and function improvement.

RESULTS

Thirty-five studies with 1674 participants (1876 tendons) were enrolled in this article. Of which 29 articles were included in meta-analysis and the remaining 9 articles without enough numeric data were included in descriptive analysis. PUNT significantly alleviated pain with the standard mean difference of 2.5 (95% CI: 2.0-3.0; p < 0.05), 2.2 (95% confidence interval (CI): 1.8-2.7; p < 0.05), and 3.6 (95% CI: 2.8-4.5; p < 0.05) points in short-term, intermediate-term, and long-term follow-up intervals, respectively. It was also associated with marked improvement in function with 1.4 (95% CI: 1.1-1.8; p < 0.05), 1.8 (95% CI: 1.3-2.2; p < 0.05), and 2.1 (95% CI: 1.6-2.6; p < 0.05) points, respectively in short-term, intermediate-term, and long-term follow-ups.

CONCLUSION

PUNT improved pain and function at short-term intervals with persistent results on intermediate- and long-term follow-ups. PUNT can be considered an appropriate minimally invasive treatment for chronic tendinopathy with a low rate of complications and failures.

CLINICAL RELEVANCE

Tendinopathy and fasciopathy are two common musculoskeletal complaints that can cause prolonged pain and disability. PUNT as a treatment option could improve pain intensity and function.

KEY POINTS

• The best improvement in pain and function was achieved after the first 3 months following PUNT and was continued to the intermediate- and long-term follow-ups. • No significant difference was found between different tenotomy methods in terms of pain and function improvement. • PUNT is a minimally invasive procedure with promising results and low complication rates for treatments of chronic tendinopathy.

Ultrasound-guided tenotomy for lateral epicondylitis with TenJet improves physical functional and decreased pain outcomes at 1 year: a case series review

Background

Common extensor tendinopathy is a common cause of lateral elbow pain. Ultrasound-guided minimally invasive tenotomy (MIT) has been utilized successfully as a treatment for several years, but the use of TenJet device has not been well described.

Purpose

To evaluate the effectiveness and safety of MIT with TenJet who failed nonsurgical management of common extensor tendinopathy in an outpatient setting.

Methods

A total of 100 patients with common extensor tendinopathy who failed conservative treatment underwent ultrasound-guided MIT with TenJet device in the outpatient setting at a single institution. All 100 patients prior to MIT underwent diagnostic musculoskeletal ultrasound showing common extensor tendinosis. The findings were interpreted by a fellowship-trained and board-certified musculoskeletal radiologist. Patients were evaluated with the Oxford Elbow Score prior to the procedure and at 1-year follow-up. Exclusion criteria included prior corticosteroid injection within the past 6 weeks of the MIT intervention, active local or systemic infection, complete full thickness tear of the common extensor tendon, and pregnancy.

Results

Oxford Elbow Score had a statistically significant difference in baseline to 1 year (P < .001). No complications were reported and zero patients went on to require open surgical intervention.

Conclusion

MIT with TenJet is a safe, effective, and well-tolerated treatment for common extensor tendinopathy.

Recommended Musculoskeletal and Sports Ultrasound Terminology: A Delphi-Based Consensus Statement

OBJECTIVES

The current lack of agreement regarding standardized terminology in musculoskeletal and sports ultrasound presents challenges in education, clinical practice, and research. This consensus was developed to provide a reference to improve clarity and consistency in communication.

METHODS

A multidisciplinary expert panel was convened consisting of 18 members representing multiple specialty societies identified as key stakeholders in musculoskeletal and sports ultrasound. A Delphi process was used to reach consensus which was defined as group level agreement >80%.

RESULTS

Content was organized into seven general topics including: 1) General Definitions, 2) Equipment and Transducer Manipulation, 3) Anatomic and Descriptive Terminology, 4) Pathology, 5) Procedural Terminology, 6) Image Labeling, and 7) Documentation. Terms and definitions which reached consensus agreement are presented herein.

CONCLUSIONS

The historic use of multiple similar terms in the absence of precise definitions has led to confusion when conveying information between colleagues, patients, and third-party payers. This multidisciplinary expert consensus addresses multiple areas of variability in diagnostic ultrasound imaging and ultrasound-guided procedures related to musculoskeletal and sports medicine.

ICON 2020-International Scientific Tendinopathy Symposium Consensus: A Scoping Review of Psychological and Psychosocial Constructs and Outcome Measures Reported in Tendinopathy Clinical Trials

OBJECTIVE

To identify and describe the psychological and psychosocial constructs and outcome measures used in tendinopathy research.

DESIGN

Scoping review.

LITERATURE SEARCH

We searched the PubMed, EMBASE, Scopus, Web of Science, PEDro, CINAHL, and APA PsychNet databases on July 10, 2021, for all published studies of tendinopathy populations measuring psychological and psychosocial factors.

STUDY SELECTION

Studies using a clinical diagnosis of tendinopathy or synonyms (eg, jumper's knee or subacromial impingement) with or without imaging confirmation.

DATA SYNTHESIS

We described the volume, nature, distribution, and characteristics of psychological and psychosocial outcomes reported in the tendinopathy field.

RESULTS

Twenty-nine constructs were identified, including 16 psychological and 13 psychosocial constructs. The most frequently-reported constructs were work-related outcomes (32%), quality of life (31%), depression (30%), anxiety (18%), and fear (14%). Outcome measures consisted of validated and nonvalidated questionnaires and 1-item custom questions (including demographics). The number of different outcome measures used to assess an individual construct ranged between 1 (emotional distress) and 11 (quality of life) per construct.

CONCLUSION

There was a large variability in constructs and outcome measures reported in tendinopathy research, which limits conclusions about the relationship between psychological and psychosocial constructs, outcome measures, and tendinopathies. Given the wide range of psychological and psychosocial constructs reported, there is an urgent need to develop a core outcome set in tendinopathy.

Cell-based therapy of the elbow: evidence for lateral tendinopathy-a review on current treatments

PURPOSE

Cell-based therapies are on the rise in treating intra and extraarticular pathologies, trying to avoid surgical intervention and support local repair processes. Therefore, the aim was to summarize current evidence-based treatment options for a cell-based therapy around the elbow.

METHODS

Through a literature review up-to date treatment algorithms and therapies have been identified and have been rated according to their evidence level for clinical recommendation.

RESULTS

Regarding the four extraarticular anatomical regions of the elbow (anterior, medial, posterior and lateral) and the joint itself, the lateral elbow and its´ tendinopathies as well as the use of cell-based treatment options have been extensively studied and, therefore, allow for clear and evidence-based recommendations. The remaining three regions as wells as the intraarticular application do not show enough evidence for a clinical recommendation.

CONCLUSION

In conclusion the cell-based approach for treating elbow pathologies can only be recommended for the lateral elbow, as there has been shown sufficient evidence for the extraarticular application. It has to be mentioned, that the results from the lateral elbow maybe transferred to other extra-articular tendinopathies, as the lack of evidence may be due to the rare appearance of posterior, medial and anterior tendon affection. No recommendation can be given for intra-articular use.

LEVEL OF EVIDENCE

IV.

The Safety of Ultrasound Guided Tenotomy and Debridement for Upper and Lower Extremity Tendinopathies: A Retrospective Study

BACKGROUND

Ultrasound guided tenotomy (USGT) is a minimally invasive treatment option for patients with chronic tendinopathy. There are conflicting findings in the literature with some studies reporting severe complications and others reporting none. This variability is likely due to the small sample sizes of previous studies. We aimed to evaluate the risks associated with USGT and outcomes across multiple tendinopathy/fasciopathy sites in a large clinical sample.

METHODS

Patients who had USGT were identified by retrospective review of charts. Complications, satisfaction, and outcomes (pain, quality of life) were assessed at baseline prior to the procedure (outcomes only), short-term follow up, and long term follow up.

RESULTS

A total of 262 patients with 289 procedures were identified through chart review. There was a low complication rate of 0.7% including one superficial wound infection and one case of wound hypersensitivity. The majority of patients reported improvement in pain by short-term and long-term follow-up and improvement in function by long-term follow-up. The majority of responders reported being either 'very satisfied' or 'somewhat satisfied' with the procedure at short-term follow-up.

CONCLUSION

This study found that USGT is a safe procedure with a low complication rate in a heterogeneous sample. Study findings provide preliminary evidence on the utility of USGT to reduce pain and improve function with a high rate of patient satisfaction.Level of Evidence: IV.

Ultrasonic Tenotomy and Debridement for Calcific Tendinopathy of the Shoulder: A Pilot Case Series

Calcific tendinopathy of the rotator cuff is a common cause of shoulder pain and debility. Minimally invasive treatment options have been employed for management; however, ultrasonic tenotomy has not been previously described for management of calcific tendinopathy of the shoulder. The purpose of the current case series was to provide preliminary evidence in support of a novel treatment modality for calcific tendinopathy of the rotator cuff. This descriptive pilot case series included a total of 8 patients with calcific tendinopathy of the supraspinatus that underwent ultrasound-guided ultrasonic debridement in the sports medicine clinic. All procedures were performed by the same physician (JLE). All patients had confirmation of the diagnosis with MRI and ultrasound imaging. Pain was measured pre-procedure and followed until 3-months post-procedure. Very large, statistically significant, reductions (P < .01) in pain scores were observed at 1 (ES = 1.93), 2 (ES = 1.84) and 3 (ES = 2.20) months post-procedure, respectively. All patients experienced a significant reduction in pain scores, regardless of hardness of the calcium deposit, at 1 month post-procedure with pain scores remaining lower than at baseline at 2 and 3 months post-procedure. No adverse events were noted in any patients. Ultrasonic tenotomy and debridement appears to be a safe and effective treatment option for patients with calcific tendinopathy of the supraspinatus.

Orthobiologics in Elbow Injuries

Orthobiologics are exciting tools providing promising results for difficult orthopedic conditions. In the elbow there is high-level evidence for their use in lateral epicondylopathy and encouraging evidence for other elbow pathologies. This article provides an in-depth review of the current literature for the use of orthobiologics in elbow injuries.
