Ultrasound-Guided Percutaneous Tenotomy and Its Associated Pain Reduction and Functionality Outcomes in Nonelite Active Adults

Abstract

Objective: The aim of this study was to evaluate changes in pain and functionality after ultrasound-guided percutaneous tenotomy (USGPT) for treatment of tendinopathy.

Design: This was a prospective cohort study of patients undergoing USGPT as an alternative to surgery. Nonelite, active adults completed pain and functionality assessments before USGPT. The visual analog scale (VAS) was used to quantify pain. The Lower Extremity Functionality Scale and the Disabilities of the Arm, Shoulder, and Hand were used to evaluate functionality. Repeat VAS scores were obtained at 1 wk, 1 mo, 2 mos, 3 mos, 6 mos, and 1 yr postprocedure, and repeat functionality assessments, at 1 yr postprocedure. Changes in VAS and functionality were analyzed with paired-sample t-tests.

Results: A total of 103 subjects (61 women, 42 men) underwent USGPT in the following tendons: Achilles, patellar, plantar fascia, flexor carpi ulnaris, extensor carpi radialis brevis, and supraspinatus. Subjects experienced statistically significant decreases in VAS and functionality scores at all time points. The mean VAS score decreased from 7.3 to 3.8 (P < 0.0001) 1 wk postprocedure, with a 5.8-point mean decrease at 1 yr (P < 0.0001). Lower Extremity Functionality Scale scores improved from 42.5 to 65.8 (P < 0.001) and Disabilities of the Arm, Shoulder, and Hand scores improved from 41.5 to 10.4 (P < 0.001) at 1 yr.

Conclusion: Recipients of USGPT procedures can expect to benefit from less invasive procedures and improved pain and functionality without invasive surgical procedures.
