Evaluation of the Impact of Self-rehabilitation After Foot Surgery Via a Connected Application

Hallux valgus is the most common forefoot deformity and primarily affects women. Surgical treatment involves an osteotomy of the first metatarsal to reduce the M1-M2 angle. Often, an osteotomy of the first phalanx of the big toe is performed in conjunction to reduce the M1-P1 angle. Once the deformity has been corrected, the second objective is to restore the foot's function, particularly mobility and plantar flexion strength. To achieve this, rehabilitation is prescribed, but inconsistently due to the lack of clear guidelines and limited patient participation, especially outside of the physiotherapist's scheduled appointments. Continuous passive range of motion exercises can accelerate the return to standard footwear and normal joint mobility. This study is based on the hypothesis that an application connected with rehabilitation exercises to be done outside of sessions with a physiotherapist reproduces this mechanism of continuous passive mobility. In this context, it is hoped that patients benefiting from self-rehabilitation of the foot via the connected application, in addition to traditional care with a physiotherapist, will achieve better postoperative mobility of the metatarsophalangeal joint of the hallux compared to traditional care with a physiotherapist in patients undergoing hallux valgus surgery, with an isolated procedure on the first ray. The main objective is to compare the mobility of the metatarsophalangeal joint of the hallux 6 months after an operation for isolated hallux valgus by osteotomy in patients benefiting from optimized rehabilitation with a physiotherapist using a connected application compared to patients receiving standard care with a physiotherapist.
