The role of metatarsophalangeal joint arthroscopy in hallux rigidus treatment: technique and early results

Abstract

Introduction: The hallux rigidus is a term that signifies a mobility limitation of the metatarsophalangeal joint of the big toe due to osteoarthritic degeneration. Several factors are incriminated in the appearance of this pathology but without being able to establish the cause. The cartilaginous erosion of the metatarsal head and / or the base of the phalange, the dorsal osteophyte of the head of the first metatarsal were found during cadaveric studies. The main reason for consultation is pain and limitation of the dorsiflexion of the big toe during the step. Hypothesis: Arthroscopic debridement of the first metatarsophalangeal joint improves the early postoperative clinical score compared to isolated percutaneous treatment. Material and method: 11 patients divided into 2 groups were assessed clinically at 3 months postoperatively. All patients were hospitalized on an outpatient basis. Results: There was a gain in mobility at 3 months compared to the preoperative assessment in both groups, as well as an improvement in pain without being able to demonstrate the superiority of the additional arthroscopy to the percutaneous debridement. Hypothesis reversed.
