Interpositional arthroplasty for the treatment of hallux rigidus (HR) involves resection of the diseased joint surface and placement of spacer material within the joint to preserve length at the metatarsophalangeal joint while still allowing for range of motion. The majority of studies available in the literature have focused on capsular interpositional arthroplasty, revealing generally positive outcomes. Other forms of interpositional arthroplasty are less supported by long-term follow-up and large sample sizes. Moreover, there exists substantial heterogeneity in the studies evaluating interpositional arthroplasty. Despite the limitations of the current data, interpositional arthroplasty seems to be a viable treatment option for HR. Copyright © 2023 Elsevier Inc. All rights reserved.
