The HemiCAP\u00ae prosthesis is the first implant used for resurfacing the metatarsal head in HR treatment. The aim of our study was toevaluate the early results of the HemiCAP\u00ae prosthesis for the treatment of HR.\\r\\nMethods: A total of 27 toes of 25 patients with MTP arthritis of the great toe were treated with an Arthrosurface\u00aeHemiCAP\u00ae resurfacing implant. The average follow-up time was 37.6 (range: 30 to 43) months. All patients were evaluated clinically and radiographically. Postoperative satisfaction and function were scored according to the American Orthopaedic Foot and Ankle Society (AOFAS) score. Pain was assessed with the use of a visual analogue scale (VAS) ranging from 0 to 10, with 0 indicating the absence of pain and 10 describing the worst pain imaginable. \\r\\nResults: Mean preoperative AOFAS score improved from 40.94 (range: 25 to 63) to 85.1 (range: 54 to 98) at the final follow-up (p&lt;0.0001). Preoperative average VAS pain scores improved from 8.30 preoperatively to 2.05 at the final follow-up (p&lt;0.0001). The average MTP joint range of motion (ROM) the improved from 14.36 degrees preoperatively to 54.38 degrees at the final follow-up. No radiologic loosening or osteolysis was observed in patients with HemiCAP\u00ae implant. \\r\\nConclusion: The early results of the HemiCAP\u00ae implant on the metatarsal head are promising. However, studies over a longer period involving more patients would be beneficial in terms of defining and reviewing the stability of the implant and any innovations in the treatment strategy for HR.\n\n\n\u00d6zet\n\nAma\u00e7: Birinci metatarsofalengeal (MTP) eklemde metalik implantlar halluks rijidus (HR) tedavisinde uzun y\u0131llard\u0131r kullan\u0131lmaktad\u0131r.
