Abstract
Objectives: To clarify the difference of patient-based outcome between joint-preserving arthroplasty and resection-replacement arthroplasty in forefoot surgery for patients with rheumatoid arthritis (RA).Methods: A total of 63 feet of 49 RA patients who underwent forefoot surgery were asked to answer pre-operative and post-operative self-administered foot evaluation questionnaire (SAFE-Q). Patients were treated with either (1) metatarsal head resection-replacement arthroplasty (28 feet, post-operative mean age 63.8 years, follow-up 4.2 years, DAS28-CRP 2.2) or (2) metatarsophalangeal joint-preserving arthroplasty (35 feet, post-operative mean age 63.1 years, follow-up 3.6 years, DAS28-CRP 2.1) at each surgeon’s discretion.Results: Mean pre-operative and post-operative subscale scores of SAFE-Q of group (1) and (2) were as follows. Pain and pain-related [(1) pre-op 36.8 to post-op 75.0 vs. (2) pre-op 42.2 to post-op 82.6], physical functioning and daily-living [(1) 43.2–68.8 vs. (2) 52.778.1], social functioning [(1) 44.3–72.0 vs. (2) 52.5–81.9], general health and well-being [(1) 48.4–68.4 vs. (2) 45.5–84.4], and shoe-related [(1) 30.1–50.3 vs. (2) 30.6–64.4]. Both general health and well-being subscale scores (p < 0.05) and shoe-related subscale scores (p < 0.05) were significantly more improved in group (2) compared with group (1).Conclusions: Joint-preserving arthroplasty resulted in better patient-based outcomes than resection-replacement arthroplasty.
