Abstract
Introduction: The treatment of stage 3 hallux rigidus is controversial. Cheilectomy, fusion and total joint replacement have all been advocated. No consensus is agreed on the best optimal management. We present our results of a ceramic on ceramic MOJE metatarsophalangeal (MTP) joint replacement.
Aim: To find out the medium to long term outcome following MOJE MTP joint replacement.
Material and Methods: A sample of 95 patients was identified, between January 1999 to July 2006 from our data base who underwent MOJE metatarsophalangeal joint replacement. We divided these patients into three groups. First group had screw fit ceramic MOJE joint replacement; second group Mark 1 ceramic on ceramic press fit MOJE joint replacement and third group Mark 2. Indications of the surgery were osteoarthritis (primary or secondary), osteochondral defects, inflammatory arthropahty, previous infections and previously failed surgery. The outcome was analysed clinically, radiologically and functionally (using AOFAS and QALY scoring system).
Results: This study shows that the early results are promising but the medium and long term results show early radiological loosing. The significance of this is not known but based on these results we would advice caution on the use of these implants and further long term studies are required.
