Prosthetic replacement arthroplasty as a salvage operation for failed procedures of the first metatarsophalangeal joint: A small series and literature review

Mid-term Results of the MOJE Hallux MP Joint Replacement

“…13 As well as providing a possible surgical solution to painful hallux rigidus, the Moje has also been used as a salvage opera tion for other failed procedures such as excision arthroplasty or arthrodesis. 24 • 25 Zirconia has the highest strength and best wear characteristics of all ceramic materials. 18 The fine grain size allows for extremely smooth surfaces and it is also said to be highly biocompatible.…”

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.…”

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

“…2,4,18 Treatments for more advanced cases include excisional arthroplasty (Keller's), or fusion, the latter being considered by many to represent the gold standard. 1,10,15,19 However, both procedures carry the risk of specific complications, including nonunion, malalignment (following arthrodesis), transfer metatarsalgia, MTPJ instability and impaired hallux control (following Keller's). 5,9,15 Several prosthetic designs for total joint arthroplasty for the first MTPJ have been developed with the aim of eliminating pain, while preserving the length and function of the hallux.…”

“…1,10,15,19 However, both procedures carry the risk of specific complications, including nonunion, malalignment (following arthrodesis), transfer metatarsalgia, MTPJ instability and impaired hallux control (following Keller's). 5,9,15 Several prosthetic designs for total joint arthroplasty for the first MTPJ have been developed with the aim of eliminating pain, while preserving the length and function of the hallux. Varying degrees of short-term success have been described with such implants, but no proven longevity has been established to date 9 -11 and a range of designs and materials has been employed, including silicone, silastic, polyethylene, cobalt-chrome, titanium and ceramic.…”

“…Even with this shorter followup some failures were still noted, although these were deemed less significant to the high AOFAS scores and patient satisfaction levels. 3,10,12,15,16 In comparison, our study has focused on longer term functional outcomes and complication rates; our series shows a significantly wider spectrum of outcome scores and satisfaction levels. Interestingly, despite the relatively limited ROM found in many of our patients, this was not obviously associated with lower satisfaction levels.…”
