Joint-preserving surgery for the forefoot has been increasingly performed for rheumatoid arthritis (RA). We compared joint-preserving surgeries with resection arthroplasty for RA in the forefoot.
Forefoot surgeries were performed on 62 toes in 42 patients with RA (men: 2; women: 40) between 2002 and 2018. Three groups were compared: PP-31 toes treated with joint-preserving surgery involving the modified Mann method for the big toe and offset osteotomy for lesser toes, PR-15 toes treated with joint-preserving surgery for the big toe and resection arthroplasty for lesser toes, and RR-16 toes treated with resection arthroplasty for all the toes.
The PP group had significantly higher mean scores on a scale for RA in the foot and ankle at the latest follow-up than the RR group (86 vs. 75 points; 
Joint-preserving surgery is superior to resection arthroplasty in preventing function loss and the recurrence of hallux valgus.
