Two-component arthroplasty for advanced 1st metatarsophalangeal joint arthritis is advocated for symptomatic relief, while maintaining the mobility of the joint. In this study we analysed the outcome of the procedure, which was carried out in 13 patients (14 feet) after a mean follow-up of 25.9 months. The results were satisfactory or very satisfactory in 11 patients (12 feet) while two patients had their implant removed following complications. Increased range of motion allowed return to sports activities and wearing of desired footwear. There was good osseointegration in all cases. By maintaining mobility and normal biomechanics of 1st metatarsophalangeal joint and the length of the hallux, it provides better cosmesis and avoids problems secondary to altered biomechanics. These are early results of the procedure but longer follow-up will be needed to see if the success is maintained.
