A prospective study of forefoot arthroplasty.
The Kates et al. metatarsal head resection arthroplasty has been modified and evaluated clinically and objectively using a dynamic pedobarograph in 35 adult rheumatoid arthritis patients. Preoperatively, all patients complained of severe forefoot pain, but only 70% recorded abnormal plantar pressure measurements. After a mean follow-up time of 36 months, 91% of the patients were satisfied with the result following surgery. Forty-two feet were pain-free, 16 feet still painful but less than preoperatively, and two feet worse. Thirteen of the 18 painful feet recorded abnormal pressure, but 16 additional feet with normal pressures were symptomatic. The clinical and pedobarographic results show that, in the majority of patients, the Kates et al. forefoot arthroplasty relieves pain, improves mobility, effectively decreases high abnormal plantar pressures, and should be considered when conservative methods of treatment have failed.
