Utility of Percutaneous Ultrasonic Tenotomy for Tendinopathies: A Systematic Review

Ultrasound-Guided Percutaneous Ultrasonic Tenotomy for Refractory Patellar Tendinopathy in High-Level Athletes: A Case Series

OBJECTIVE

To elucidate the clinical outcomes and return-to-sport status of high-level athletes with refractory patellar tendinopathy treated with ultrasound-guided percutaneous ultrasonic tenotomy (PUT).

DESIGN

Case series study.

SETTING

Single orthopaedic clinic.

PATIENTS

Five cases involving 8 knees from athletes (average age: 22 years, range: 17-30 years) who presented with refractory patellar tendinopathy and underwent PUT between 2022 and 2024. Conservative treatments had previously been attempted without sufficient pain relief or return to sports.

INTERVENTIONS

All patients underwent ultrasound-guided PUT using the TX-2 device from Tenex Health. Jogging was resumed 1 month after surgery, and a return to competitive sports was permitted as early as 3 months postsurgery.

MAIN OUTCOME MEASURES

Preoperative and postoperative Victorian Institute of Sport Assessment (VISA) scores and Numerical Rating Scale (NRS) scores for pain. Time to return to full training and competitive sports, and presence of postoperative infection signs.

RESULTS

The VISA score significantly improved from a preoperative average of 43.1 to a postoperative average of 77.1 (P = 0.0004). The NRS significantly decreased from a preoperative average of 6.4 to a postoperative average of 2.8 (P = 0.0005). Four cases involving 6 knees fully returned to sports, with an average return time of 3 months and 19 days (range: 3 months to 4 months and 13 days). One case involving 2 knees did not show sufficient pain improvement and the patient could not return to sports. No signs of infection were observed in any case.

CONCLUSIONS

PUT for refractory patellar tendinopathy in high-level athletes generally results in favorable treatment outcomes and successful return to sports. This study provides novel insights into the effectiveness of PUT for patellar tendinopathy in athletes, highlighting the need for future studies with larger sample sizes to validate these findings and explore factors associated with poor outcomes.

Ultrasonic Fasciotomy for the Treatment of Chronic Plantar Fasciopathy: A Prospective Study

OBJECTIVE

To evaluate the long-term efficacy and safety of an ultrasonic fasciotomy for plantar fasciopathy.

DESIGN

Prospective observational study.

SETTING

Tertiary care academic medical center.

PARTICIPANTS

Patients with chronic plantar fasciopathy refractory to standard, conservative treatments were included in this study.

INTERVENTIONS

Patients underwent ultrasonic fasciotomy of the plantar fascia.

MAIN OUTCOME MEASURES

The primary outcome measures were change in visual analog scale at 12 and 52 weeks post-procedure compared with baseline as well as patients' self-reported satisfaction with the procedure.

RESULTS

Sixty-seven patients were included. There was a significant improvement in visual analog scale at all follow-up time points, with an average overall improvement of 5.87 ( P < 0.0001). 94% of patients reported satisfaction with the outcomes of their procedure at 12 and 52 weeks. No procedural complications were seen.

CONCLUSIONS

This study demonstrates that an ultrasonic fasciotomy is a safe and effective treatment option for chronic plantar fasciopathy, with continued symptom improvement and a high degree of patient satisfaction up to 52 weeks post-procedure.

CLINICAL RELEVANCE

These findings suggest that an ultrasonic fasciotomy should be considered for patients with chronic plantar fasciopathy refractory to conservative treatments.

Percutaneous needle tenotomies: indications, procedures, efficacy and safety. A systematic review

BACKGROUND

Percutaneous needle tenotomies constitute a promising approach that enables direct access to tendons through minimally invasive interventions. They can be performed rapidly without need for large incisions or general anaesthesia. However, the reported procedures are heterogeneous and currently conducted without guidelines.

OBJECTIVES

We aimed to determine the indications for percutaneous needle tenotomies described in the current literature. Our secondary aim was to identify the different procedures reported, as well as their efficacy and their safety.

METHODS

A systematic review following PRISMA guidelines was conducted to identify original articles that mentioned percutaneous needle tenotomy in humans and reported its application, description, effectiveness or adverse events. Non-percutaneous tendinous surgical procedures and ineligible designs were excluded. The Downs and Black checklist was used to assess the risk of bias.

RESULTS

A total of 540 studies were identified from the MEDLINE, Embase, Cochrane Library, and PEDro databases. Fourteen clinical studies met the inclusion criteria and were found to have an acceptable quality (674 individuals, 1664 tenotomies). Our results indicated a wide variety of indications for percutaneous needle tenotomies in children and in adults. We highlighted 24 tendons as eligible targets in the upper and lower limbs. Tenotomies were performed with either 16- or 18-Ga needles, lasted from 1 to 30 min, and were performed using various procedures. Their efficacy was mainly assessed through clinical outcomes highlighting tendon discontinuity on palpation after the procedure. Passive range-of-motion gains after tenotomy were reported for both upper and lower limbs with an estimated 5 % complication rate.

CONCLUSION

This is the first review to systematically synthesize all the available evidence on the indications, procedures, efficacy and safety of percutaneous tenotomies exclusively performed with needles. Current evidence suggests that procedures are safe and effective for treating various deformities.

Percutaneous Interventions for Injuries in Athletes: Implications on Return to Play

For nonsurgical musculoskeletal (MSK) injuries in athletes, image-guided percutaneous intervention may aid in recovery and decrease return to play (RTP) time. These interventions fall into two major categories: to reduce inflammation (and therefore alleviate pain) or to promote healing. This review describes the risks and benefits of the various percutaneous interventions in MSK athletic injury and surveys the literature regarding the implication of these interventions on RTP.

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.

Retrospective Evaluation of Ultrasound Guided Percutaneous Plantar Fasciotomy With and Without Platelet Rich Plasma

Plantar fasciitis is one of the most common foot conditions presenting to a foot and ankle specialist. Surgical treatment outcomes following plantar fasciotomy vary but short-term studies have reported excellent early pain relief and significant improvements in symptoms. This study evaluates patient reported pain scores collected pre- and post-op for patients who underwent percutaneous ultrasonic microtenotomy (PUT) plantar fasciotomy with PRP injection vs without the use of PRP. We compared pain visual analog scale (VAS) scores, for patients treated surgically by Orthopedic Surgery department of foot and ankle faculty members between December 2007 and December 2022. A total of 30 patients were identified that met inclusion and exclusion criteria. Our results showed that there was a significant decrease in pain VAS scores from pre-op visit (at least 1 month prior to operation) to post-op visit (at least 1 month following operation) for both groups, with a paired t test (p value <.0001). However, patients who received PRP had a statistically significant decrease in pain level compared to the group who did not receive PRP. Statistical analysis completed with a 2-sample t test (p-value <.0325). Our results found the mean time between the initial pre-op visit and last post-op follow-up visit was 19 months. The mean for time following surgical intervention was 10 months. The findings of our study suggest that the dual use of PUT and PRP to treat plantar fasciitis, could potentially lead to an improvement in pain reduction and longevity of pain relief.

Ultrasound-guided treatment of medial collateral ligament calcification of the knee with TenJet™: a case report

Calcification of the medial collateral ligament is a rare cause of medial knee pain along with functional impairment. Most cases are asymptomatic but those that are symptomatic typically respond to conservative management. However, in those instances with persistent symptoms that desire further intervention but want to minimize the risks associated with surgery, we present a novel approach for calcium removal with an ultrasound-guided percutaneous needle tenotomy with TenJet™ as a reasonable treatment modality.

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.

Ischiofemoral Impingement Due to an Undiagnosed Pelvic Avulsion Fracture

ABSTRACT

Ischial tuberosity (IT) avulsion fractures are an uncommon cause of injuries in athletes. In this case, a 26-year-old female suffering from posterior right hip pain for over a decade presented with debility and a decrease in athletic function. Notable history included a hamstring strain while sprinting in elementary school. Clinical examination suggested hamstring tendinopathy and ischiofemoral impingement (IFI). Magnetic resonance imaging (MRI) revealed a chronic, fragmented, IT apophyseal avulsion fracture with ischial bursitis and edema within the fragmented bone, suggesting the development of heterotopic ossification (HO). Diagnostic ultrasound revealed signs of IFI, not evident on MRI. Ultrasound-guided corticosteroid injection in her ischial bursa and ischiofemoral space provided complete relief. The patient was able to resume her activities of daily living and sports-related activities without pain. Although interventional treatments may provide temporary pain relief, a multimodal approach is required for the treatment of HO.

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.

BESS patient care pathway: Tennis elbow

This article provides a guidance summary for the management of lateral elbow tendinopathy (LET) using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system of the rating quality of the literature and grading the strength of available evidence. The process began by assembling a guideline development group of volunteers including orthopaedic surgeons, trainees, physiotherapists, rheumatologists, radiologists and patients. Virtual meetings were organised to set out explicit PICO questions, including specification of all important outcomes (including patient reported tennis elbow evaluation (PRTEE) as an important primary outcome) to determine the clinical effectiveness of common treatment options for LET compared with no treatment or placebo. Clinical librarian searched (date 31 April 2022) for available systematic reviews and randomised controlled trials reviewing the management of the LET January 2011 onwards and evidence was collected and summarized using explicit GRADE criteria for rating the quality of evidence that include study design, risk of bias, imprecision, inconsistency, indirectness, and magnitude of effect. Recommendations were characterized as strong or weak (alternative terms conditional or discretionary) according to the quality of the supporting evidence and the balance between desirable and undesirable consequences of alternative management options. This informative summary provides the quality of available evidence for the management of LET.

The effectiveness of percutaneous ultrasound-guided needle tenotomy compared to alternative treatments for chronic tendinopathy: a systematic review

OBJECTIVES

To compare percutaneous ultrasound-guided needle tenotomy (PUNT) to alternative treatments for chronic tendinopathy.

MATERIALS AND METHODS

A systematic literature search was performed with the following combination of keywords: ultrasound-guided, percutaneous, needling, tenotomy, Tenex, tendinopathy, and fasciotomy. Original studies comparing PUNT to alternative treatments for chronic tendinopathy were included in this systematic review.

RESULTS

Twelve (n = 12) studies with 481 subjects were included. Two (2/12) articles compared PUNT to surgical tenotomy and concluded that PUNT provides the same outcomes as surgical tenotomy. Six (6/12) studies compared PUNT to platelet-rich plasma (PRP) injections, and two of them found both treatment modalities effective with no significant between-group differences. Three trials claimed that PUNT followed by PRP injections showed superior clinical outcomes compared to PUNT alone. However, the difference at long-term follow-up was statistically significant only in one of them. One study found PUNT superior to PUNT + PRP injection at short-term follow-up, although there were no between-group differences at long-term follow-up. Four (4/12) studies compared PUNT to steroid injection (SI) and showed that SI causes fast (2 weeks) but temporary pain relief, PUNT results in persistent but relatively slower improvement to SI, and the combined procedure has a more rapid and steady reduction in symptoms.

CONCLUSION

PUNT is an effective treatment technique for chronic tendinopathy and should be considered when non-invasive treatments have failed. Effects of PRP and SI are transient and dissipate over time and do not contribute to long-term outcome.

Emerging Treatment Options for Chronic Tendinopathy of the Foot: A Clinical Vignette

ABSTRACT

The patient is a 65-year-old female recreational skier and avid walker who presented with a several-month history of right ankle and foot pain. The patient's pain began without inciting event and was described as a constant aching pain aggravated by downhill walking and alleviated with rest. She was diagnosed with right distal tibialis anterior tendinopathy with partial thickness tear noted on magnetic resonance imaging and musculoskeletal ultrasound. Given symptoms recalcitrant to conservative measures, the patient opted to pursue an ultrasound-guided prolotherapy injection and a course of physical therapy; unfortunately, she did not have any improvement in symptoms. The patient subsequently underwent ultrasound-guided percutaneous ultrasonic tenotomy and debridement of the distal tibialis anterior tendon, followed by a postprocedure rehabilitation protocol of physical therapy with transition to home exercise program with complete resolution of her pain. Prolotherapy, and percutaneous ultrasonic tenotomy and debridement are two treatment modalities that show promise in the treatment of painful, chronic tendinopathy.

Interventional Imaging Techniques as Alternative to Surgery of the Foot and Ankle

A variety of foot and ankle pathologies can impair patient's daily activities, ultimately requiring surgical management. However, with improvements in image-guided intervention, the joints, soft tissues, and osseous structures may be accessible using various percutaneous techniques as a potential alternative therapeutic tool, avoiding the need for surgery with its associated risks and morbidity. This article discusses the potential range of image-guided interventional treatments. Injections, aspiration, biopsies, cryoablation, and radiofrequency ablation are described. Newer novel treatments are also covered. Finally, the common pathologies of Morton's neuroma, Achilles tendinopathy, and plantar fasciitis are addressed.

Nonoperative Management of the Achilles Tendon Insertion

Insertional Achilles tendinopathy can be a very challenging clinical syndrome with various nonoperative measures typically attempted before surgical intervention. Associated complications are known with surgical repair and can be limb altering. Owing to the longevity of clinical symptoms before clinical presentation, changing the pathophysiologic process and halting the inflammatory changes becomes paramount. Here we discuss nonoperative techniques and updates in the foot and ankle literature.

Efficacy of ultrasound therapy for the treatment of lateral elbow tendinopathy (the UCICLET Trial): study protocol for a three-arm, prospective, multicentre, randomised controlled trial

INTRODUCTION

Lateral elbow tendinopathy (LET) is a highly prevalent disease among the middle-aged population, with no consensus on optimal management. Non-operative treatment is generally accepted as the first-line intervention. Ultrasound (US) therapy has been reported to be beneficial for various orthopaedic diseases, including tendinopathy. The purpose of this study is to investigate the efficacy of US for LET treatment.

METHODS AND ANALYSIS

This protocol entails a three-arm, prospective, multicentre, randomised controlled trial. Seventy-two eligible participants with clinically confirmed LET will be assigned to either (1) US, (2) corticosteroid injections or (3) control group. All participants will receive exercise-based therapy as a fundamental intervention. The primary outcome is Patient-rated Tennis Elbow Evaluation. The secondary outcomes include Visual Analogue Scale for pain, shortened version of the Disabilities of the Arm, Shoulder and Hand for upper limb disability, pain free/maximum grip strength, Work Limitations Questionnaire-25 for functional limitations at work, EuroQol-5D for general health, Hospital Anxiety and Depression Scale for mental status, Global Rating of Change for treatment success and recurrence rate, and Mahomed Scale for the participant's satisfaction. Adverse events will be recorded. Intention-to-treat analyses will be used.

ETHICS AND DISSEMINATION

Ethics committees of all clinical centres have approved this study. The leading centre is Shanghai Sixth People's Hospital, whose approval number is 2021-153. New versions with appropriate amendments will be submitted to the committee for further approval. Final results will be published in peer-reviewed journals and presented at local, national and international conferences.
