Ultrasound-Guided Tenotomy Via a Hydrosurgery Resection Device Improves Symptoms of Chronic Elbow Tendinopathy: A Multi-Center Prospective Study

Abstract

Objectives To test the hypothesis that ultrasound-guided, minimally invasive tenotomy using the TenJet™ resection device might provide symptomatic pain relief and functional recovery to patients with chronic tennis or golfer’s elbow. Methods This multi-center, prospective, single-arm study enrolled patients who experienced pain symptoms persisting >3 months, failed conservative care, demonstrated ultrasound or magnetic resonance imaging findings consistent with the diagnosis of tendinosis, and had opted for ultrasound-guided treatment using the TenJet resection device. Post-procedure follow-ups occurred at 2 and 6 weeks and 3, 6, and 12 months. Outcome measures included a patient-rated elbow evaluation (PREE) questionnaire for pain and function, visual analog scale (VAS) for pain, procedure complications, and adverse events. Results A total of 29 patients (32 elbows) were enrolled in the study. Significant improvements in mean PREE total scores and mean VAS scores were observed at all follow-up time points (both p < 0.05). There were no device malfunctions or procedure-related complications. Two patients (6.9%) proceeded to have open debridement, one after the 2-week follow-up visit and the other after the 3-month follow-up visit. Conclusion Ultrasound-guided tenotomy and debridement using the TenJet resection device provided patients with significant pain relief and functional recovery. Additional studies may be necessary to further validate the clinical outcomes observed in this study.
