We reviewed the results of the Keller arthroplasty in combination with resection arthroplasty of the forefoot in patients with rheumatoid arthritis. Of the 29 patients (49 feet) in the series, 20 had involvement of both feet and nine had involvement of a single foot. The average age of the patients was 55.4 years, and the average follow-up period was 4.9 years. All feet had resection of the lesser metatarsal heads, resection of the base of the proximal phalanges of the lesser toe, and a Keller arthroplasty of the first metatarsophalangeal joint. The results were satisfactory in 16 feet, satisfactory with some reservations in 21 feet, satisfactory with major reservations in seven feet, and unsatisfactory in five feet. For 40 of the 49 feet (82%), the patients stated that they would repeat the procedure, knowing the results achieved. The major causes of patient reservations and lack of satisfaction were return of the hallux valgus deformity and pain (53%), forefoot instability (27%), and continuing metatarsalgia (20%). Resection arthroplasty of the lesser metatarsophalangeal joints of the forefoot in rheumatoid disease is a satisfactory procedure. When used in combination with Keller resection arthroplasty of the first metatarsophalangeal joint, however, an increased number of unsatisfactory results occur, attributable to returning pain and deformity of that joint.
