The case against first metatarsal phalangeal joint implant arthroplasty.
This article argues the practice of first metatarsal phalangeal joint (MPJ) implant arthroplasty. Intermediate and long-term studies raise concerns about implant failure and longevity. Other causes for concern are silicone-induced synovitis and lymphadenopathy. This article presents evidence against the practice of first metatarsal phalangeal implant arthroplasty. Intermediate and long-term studies raise concerns about implant failure and longevity. Furthermore, the lack of any significant long-term results and the documented metallic breakdown from two-piece metallic implants make their use in hallux rigidus questionable. Meanwhile, a comparative study shows the superiority of arthrodesis to implant arthroplasty. Also, alternatives to joint-destructive procedures are emerging. These include arthrodiastasis and the osteochondral autograft transfer procedure. This evidence proves that implant arthroplasty is not the best treatment for patients with hallux rigidus or other first-MPJ pathology.
