Abstract
Objective The objective of this study was to determine the involvement of the foot as the first manifestation in rheumatoid arthritis (RA). Methods This study was conducted on 100 patients who presented to the outpatient department of the Rheumatology Department at Fatima Memorial Hospital and College of Medicine and Dentistry in Lahore, Pakistan. The period of this cross-sectional study was three months - from October 2017 to December 2017. One hundred patients aged more than 16 years, who were diagnosed as cases of RA with foot involvement, and with a disease duration of less than two years (to minimize recall bias), were enrolled for the study. Results Out of the 100 patients, 20% were male and 80% were female. The mean age of the study population was 41.16 ± 12.343 years. Foot Involvement as the first manifestation was noted in 29 (29%) of the cases. The pattern of foot involvement shows a 59% forefoot involvement, 27% hindfoot involvement, and 14% midfoot involvement. Walking difficulty was most common in forefoot involvement (71.42% of cases), followed by hindfoot involvement (20% of cases), and least common in midfoot involvement (8.57% of cases) (p=0.0001). Conclusion Foot involvement as the first manifestation is quite common in RA and should not be ignored, especially in patients with large joint involvement sparing the hands.
