From January 1987 to December 1992, 38 patients (59 feet) with rheumatoid arthritis underwent reconstruction of the forefoot using Keller-Lelièvre arthroplasty of the first metatarsophalangeal joint and Hoffman resection of the lesser metatarsal heads. The average age of the patients was 61.3 years, with both feet involved in 21 patients and 17 with single foot involvement. The aim of our study was to evaluate the results both on a functional and an objective basis using dynamic and static pedodynographic measurements. Attention was given to dynamic pressure measurements under the metatarsal heads, the center of pressure distribution, gait analysis, and peak loads taken on different areas of the forefoot during normal walking. Correlations were made between these measurements and symptoms. After a mean follow-up time of 35 months, the clinical results were satisfactory in 54%, satisfactory with some reservations in 39%, satisfactory with major reservations in 3%, and unsatisfactory in 3% of patients.
