Comparison of Clinical Outcomes of Endoscope-Assisted Technique and Conventional Surgery in Zone 2 Flexor Tendon Repair

Abstract

The purpose of the study was to compare clinical outcomes between patients who underwent endoscope-assisted flexor tendon repair and those who underwent conventional surgery. Patients were divided into 2 groups. Group 1 (endoscope-assisted surgery) included 21 patients (27 fingers) and group 2 (conventional surgery) included 19 patients (25 fingers). Outcomes assessed included the mean total active motion, Strickland classification, prevalence of rerupture, tenolysis requirement, and infection rate. The mean total active motion was 152.3° in group 1 and 134.7° in group 2, which was significantly higher in group 1 compared to group 2. An excellent or good outcome was achieved in 25 (92.5%) of the fingers in group 1 as opposed to 17 (68%) fingers in group2. We conclude that endoscope-assisted surgery is an alternative method for tendon surgery, enables a minimally invasive approach, and provides a favorable range of motion. Therapeutic IV.
