Replacement Arthroplasty of the First Metatarsophalangeal Joint Using a Ceramic-Coated Endoprosthesis for the Treatment of Hallux Rigidus

Hemiarthroplasty Versus Total Joint Arthroplasty for Hallux Rigidus: A Systematic Review and Meta-analysis

“…Although partial and total MTPJ arthroplasty has been associated with increased incidence of hardware failure, prosthetic loosening, dislocation, and subsidence of implanted material, many evolutions of implant design have subsequently attempted to improve the outcomes seen in these patients. 32,40 Despite the progression of MTPJ implant technology, it remains unclear whether hemiarthroplasty or total-surface materials are superior when seeking to recreate a joint that has complex biomechanical properties that vary by gait cycle. To our knowledge, this is the first systematic review to examine the outcomes of hemisurface and total MTPJ arthroplasty studies and perform a subsequent meta-analysis to interpret the results.…”

Total Arthroplasty of the Metatarsophalangeal Joint of the Hallux

“…24 The present data show that the MTP-I prosthesis had minimal intraoperative and perioperative complications, with no short-term complications. In the literature, perioperative complications are reported with an average of 10% of cases (eg, 4/42 cases, 1 2/26 cases 10 ), with most being wound breakdown, luxation, and periprosthetic fracture. This is comparable with the perioperative complications reported in MTP-I arthrodesis.…”

“…In terms of osteointegration, our results and another report on this implant 24 seem to be at least equal to other prosthetic designs. 1,9,27,35…”

“…In terms of osteointegration, our results and another report on this implant 24 seem to be at least equal to other prosthetic designs. 1,9,27,35 Regarding alignment and stability, comparison to other studies is difficult because none have systematically analyzed radiographic alignment. In our cohort, most cases had an intercomponent angle of greater than 5 degrees varus or valgus, and most also had tilting or shifting of the phalangeal component in relation to the metatarsal component.…”

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.…”
