Introduction: Plantar fasciitis is a common cause of heel pain in adults, with a significant impact on quality of life and athletic performance. While conservative treatments are effective in most cases, a subset of patients remains symptomatic and may require surgical intervention. Minimally invasive techniques, such as bipolar radiofrequency (RF) coblation using the TOPAZ system, have emerged as promising alternatives to traditional open or endoscopic procedures. Methods: This retrospective study evaluated the clinical outcomes of 49 consecutive patients (20 males and 29 females; mean age 54.3 ± 11.4 years; mean BMI 25.3 ± 3.2, range 21.5–34.7) with chronic plantar fasciitis unresponsive to at least six months of conservative treatment. The affected side was left in 24 patients and right in 25, and 35 patients were regularly engaged in sports prior to symptom onset. All patients underwent percutaneous bipolar RF coblation using the TOPAZ device between July 2019 and November 2024. Patient-reported outcome measures—including the Visual Analog Scale (VAS), AOFAS Ankle–Hindfoot Score, SF-36, and Tegner Activity Scale—were collected at the final follow-up (mean 41.7 ± 18.3 months, range 6–71). Results: Statistically significant improvements were observed in pain and function: mean VAS decreased from 8.5 to 3.1 (p < 0.001), and American Orthopaedic Foot and Ankle Society (AOFAS) pain and function scores improved from 2.5 and 12.75 to 28.75 and 38.75, respectively (p < 0.001). The mean Tegner score increased from 1.3 to 4.1 (p < 0.001), with 100% of previously active patients returning to sport. No major complications or reoperations were reported. Conclusions: Percutaneous bipolar RF coblation appears to be a safe and effective treatment for recalcitrant plantar fasciitis, offering significant pain relief, functional improvement, and a high return-to-sport rate with minimal morbidity. This technique may represent a valuable intermediate option between conservative care and open surgery.
