Abstract

BACKGROUND: A modern technique for the treatment of hallux rigidus (HR) is first metatarsophalangeal (MTP) hemiarthroplasty with the use of a Cartiva synthetic cartilage implant. Current scientific literature reporting early outcomes of the procedure is sparse and mixed, indicating the need for further analysis. The objective of this study was to compare improvement in visual analog scale (VAS) scores with first MTP hemiarthroplasty with Cartiva implant (HI), allograft interposition arthroplasty (IA), and arthrodesis (A) in patients who failed conservative management or cheilectomy.

METHODS: A retrospective cohort study of 99 patients was performed. There were 49 patients in the HI group, 25 patients in the IA group, and 25 patients in the A group. A follow-up survey was administered from which updated VAS and updated American Orthopaedic Foot & Ankle Society scores were obtained.

RESULTS: Mean VAS scores improved by 2.73 (SD ± 2.80) points in the HI group, 4.16 (SD ± 2.01) points in the IA group, and 4.36 (SD ± 3.67) points in the A group (

CONCLUSION: Pain and function may be slightly more improved with interpositional arthroplasty and arthrodesis for the treatment of HR, when compared to hemiarthroplasty with the Cartiva implant.

LEVEL OF EVIDENCE: Level III, therapeutic studies; case-control study.
