A catastrophic failure of a first MTP joint ceramic implant

Second-Generation Ceramic First Metatarsophalangeal Joint Replacement for Hallux Rigidus

“…The present study has the longest follow-up of all studies with this prosthesis to date ( Table 2). Previous studies with this prosthesis have included 13 case series (Table 2), 2,3,6,8,11,12,15,17,21,23,26,27,29 2 abstracts, 10,19 and 2 case reports, 13,28 and 3 previous studies have evaluated the outcome of revision procedures 32,33 or lesser toe replacement surgery 34 with this type of prosthesis.…”

Preliminary Results From the Metis-Newdeal® Total Metatarsophalangeal Prosthesis

“…Malviya et al (18) showed positive results with this new Moje system, in a 35-month follow-up study. However, other studies report cases of failure of the Moje ® press-fit prosthesis, due to problems with the materials used (zirconium ceramic) (9) . In 2007, Nixon and Taylor (2) published the results of a study involving 21 prostheses, in which they found an unacceptable failure rate of around 29% requiring surgical revision and a complication rate of 71% within three years.…”

“…However, these prostheses presented several complications, including fracture of the prosthesis and synovitis and bone lysis related to worn particles of silicone 5 , 6 , 7 . In 1994, the use of zirconium ceramic components (Moje ® ) was tested, but these materials also presented several complications, particularly due to fracture of the material 2 , 8 , 9 .…”

MOJE Ceramic Metatarsophalangeal Arthroplasty: Disappointing Clinical Results at Two to Eight Years

“…11,12 However, a number of these implants have already fallen into disrepute due to unacceptable failure or complication rates, notably in silicone, titanium and polyethylene. 5,7,11,13,16 The continuing effort to design a successful joint replacement for the first MTPJ, led to the development and introduction of the MOJE ceramic-on-ceramic (uncemented) pressfit prosthesis to the UK market in early 2000 (Figure 1). This new press-fit design replaced the original screw-fit titanium and ceramic MOJE prosthesis, which was withdrawn in the UK in 2000 due to a Medical Devices Agency alert, following reports of unacceptably high failure rates.…”
