25 First metatarso phalangeal joint replacements using the MOJE implant were prospectively assessed. There were 13 females and 10 males, with an average age of 60 years (range 45–71 years). The main indication for surgery was a symptomatic Hallux Rigidus. The minimum follow up period was 2 years (range 24–38 months). The patients were assessed before and after surgery using the AOFAS (American Orthopaedic Foot and Ankle Society Hallux Score). The mean pre operative AOFAS score was 45.60 and this improved to 85.63 after surgery. There was a significant improvement in the sub scale for pain, from 4.58 pre operatively to 31.25 post operatively. A 9.50 improvement in the range of motion was noted. The authors conclude that their study demonstrates that the use of the MOJE implant for the treatment of Hallux Rigidus is a safe and useful option, although a more long term follow up is indicated.
