The aim of this study was to evaluate functional outcomes following ceramic arthroplasty used in the treatment of osteoarthritis of the hallux metatarsophalangeal (MTP) joint.Thirty-seven consecutive patients who underwent press-fit ceramic joint arthroplasty were identified. Joint movement, gait pressure studies, radiographs, patient's outcome based on the American Orthopaedic Foot and Ankle Society...
Evidence regarding the efficacy of the MOJE ceramic press fit total joint replacement for the first metatarso-phalangeal joint (MTPJ) is lacking.Our aim was to assess the clinical outcome for the MOJE arthroplasty in a single surgeon series using objective and subjective assessment tools.A retrospective outcome study of 24 implants was performed in 22 patients undergoing first MTPJ replacement for...
Arthroplasty for hallux rigidus remains controversial. This study assesses 2–5 year outcomes of the press-fit Moje ceramic–ceramic implant.Twenty-one joints in 16 patients were reviewed clinically, radiologically and pedobarographically. Nineteen implants were in the 1st metatarsophalangeal joint (MTPJ), one in the 2nd MTPJ and one in the 3rd MTPJ.Despite good immediate pre-operative radiographs,...
There are several treatment options for hallux rigidus including arthroplasty. The objective of this study was to review 17 patients and 18 Moje joint replacements of the first metatarso-phalangeal joint. One hundred percent follow-up was achieved. Average follow-up was 18 months (range 11–31 months), average age 56 (range 36–72). They were assessed via the AOFAS scoring system and results showed...
Described below is a case of catastrophic failure of a Moje press fit first MTP ceramic implant. The failure of the device was later discovered to have occurred due to damage occurring in the manufacturing process.
Introduction: This implant seemed to overcome the failings of previous designs having a ceramic bearing attached to a titanium positional screw in the metaphyseal bone and an apatite-coated ceramic-bone interface to enhance secondary stability. On the basis of encouraging early results reported from Germany, Orthosonics Ltd. marketed the implant in the UK from June 1999. Following problems with the...
