Objective: To evaluate functional results of subtalar arthroereisis with non-conventional implants, as well as their clinical, radiographic, and functional results, comparing them with those of the conventional technique. Methods: Documentary research consisting of the analysis and review of medical records of six patients, with application of the Orthopaedic Foot and Ankle Score (AOFAS) and Short Form Health Survey 36 (SF-36) questionnaires and evaluation of pre-and postoperative radiographic results. Results: Patients achieved satisfactory clinical and functional results, indicated by an improvement in the pitch, kite, Giannestras, and Meary angles analyzed and by comparing the pre-and postoperative periods. There was also an improvement in the AOFAS and SF-36 questionnaire scores postoperatively, suggesting an evolution in the quality of life of patients studied. Conclusion: Subtalar arthroereisis is a non-invasive surgical procedure that contributes to the clinical improvement of patients. The use of interference screw showed good results, with the advantage of it being a low-cost implant when compared to the conventional ones, which makes the procedure more accessible.
