The Keller resection arthroplasty: a 13-year experience.

The clinical results following Keller resection arthroplasty were reviewed in 54 feet with a 2- to 10-year follow-up. Patients were evaluated by radiographs, physical examination, and questionnaire. The primary indication for surgery was painful hallux valgus with associated degenerative changes of the first metatarsophalangeal joint. Additionally, rheumatoid arthritis was the underlying diagnosis in four feet. Seventy-five percent of all patients had complete relief of their symptoms. There was significant (P less than .01) improvement in both the metatarsophalangeal and intermetatarsal angles, but a decreased range of motion in the first metatarsophalangeal joint, with a complete lack of plantarflexion in 67%. Application of the Bonney and MacNab2 grading system yielded a 72% rate of good and excellent results. The subjective patient satisfaction rate was 87.5%. Patient satisfaction was most strongly associated with the use of a K-wire for postoperative fixation (P = .03), and a limited resection of the proximal phalanx (P = .03). We conclude that the Keller resection arthroplasty is a reasonable alternative for the treatment of hallux valgus in the presence of degenerative changes in the first metatarsophalangeal joint.
