Abstract

OBJECTIVES:

Joint-preserving rheumatoid forefoot surgery improves clinical outcomes, but postoperative range of motion (ROM) of the metatarsophalangeal (MTP) joint remains an issue. The objective of this study was to evaluate the effect of ROM exercise from the early period after lesser toe MTP joint-preserving surgery.

METHODS:

A retrospective, observational study of 22 rheumatoid arthritis patients who underwent modified metatarsal shortening offset osteotomy was completed. Lesser toe scales were administered using the Japanese Society for Surgery of the Foot (JSSF) standard rating system, and the maximum distance of continuous walking was checked to evaluate clinical outcomes. Maximum passive ROM of the lesser toe MTP joints and the extension angle of the 2nd MTP joint at the terminal stance phase during gait were measured and evaluated.

RESULTS:

Pain scores and ROM-related indices of the JSSF lesser toe scale improved significantly in the exercise group. The extension angle of the 2nd MTP joint at the terminal stance phase during gait was increased, and the maximum distance of continuous walking seemed longer.

CONCLUSION:

Passive/active ROM exercise from 2-weeks after surgery can improve a patient's activity and forefoot function through increasing ROM of the MTP joint at the terminal stance phase.
