A June 2022 study (1) assessed risk factors for the need for secondary or revision surgery following metatarsophalangeal (MTP) joint arthroplasty.
In this study, the researchers write: “Revision or conversion to arthrodesis following metatarsophalangeal (MTP) joint arthroplasty are salvage procedures to manage complications of MTP joint arthroplasty. The purpose of this study was to evaluate demographic trends and evaluate influence of patient-related risk factors in those undergoing MTP arthroplasty (joint replacement) revision to arthrodesis (joint fusion).
- Results: 2750 patients underwent primary MTP arthroplasty for diagnosis of hallux rigidus. Of these, 44 (1.6%) underwent revision arthroplasty and 188 patients (6.8%) were revised to arthrodesis within the first 2 years after the first procedure. Multivariate regression analysis indicates that obesity, depression, and steroid use were associated with a statistically significant increase in revision to arthrodesis from primary arthroplasty.
