BACKGROUND/OBJECTIVES: Chronic plantar fasciopathy is a degenerative pathology that elicits persistent heel pain, significantly impacting quality of life. When conservative treatments fail to yield satisfactory outcomes, radiofrequency microtenotomy utilizing the Topaz technique presents a minimally invasive alternative with regenerative potential. This study aims to evaluate its efficacy in pain reduction, functional improvement, and complication rate compared to other treatments. METHODS: A systematic review was conducted in accordance with the PRISMA guidelines and registered in PROSPERO (CRD4202525648314). PubMed, EBSCOhost, Web of Science, and Scopus (2014 to 2024) were comprehensively searched to identify studies on the Topaz technique for refractory chronic plantar fasciopathy. Clinical trials, cohort studies, and case series were included, and a meta-analysis was performed using a random-effects model to assess pain, the Visual Analog Scale (VAS), American Orthopaedic Foot and Ankle Society function (AOFAS), and complications. RESULTS: Fifteen studies encompassing 1576 patients were analyzed. The meta-analysis demonstrated a significant reduction in pain of 5.90 points on the VAS scale (95% CI 5.03 to 6.77, p < 0.001) and a functional improvement of 0.28 points on the AOFAS scale (95% CI 0.27 to 0.28, p < 0.001). The complication rate was low (3.00%), with high patient satisfaction (90%) and rapid recovery. CONCLUSIONS: The findings suggest that the Topaz technique is a safe and effective option for chronic plantar fasciopathy, demonstrating significant improvements and minimal complications.
