Objective To evaluate the clinical effectiveness of the first metatarsophalangeal (MTP) joint arthroplasty versus arthrodesis for rheumatoid forefoot deformity.
Methods The randomized controlled trials (RCTs) about the first MTP joint arthroplasty vs. arthrodesis for rheumatoid forefoot deformity published by February 2012 were searched in the databases such as CNKI, Ovid, MEDLINE, CBM, EMbase, WanFang Data, The Cochrane Library (Issue 1, 2012), and KJEBM. Two reviewers independently screened studies, extracted data, and evaluated the methodological quality according to the inclusion and exclusion criteria. Then meta-analysis was conducted using RevMan 5.1 software.
Results A total of 4 RCTs were included. Among total 206 (269 feet) patients involved in, 98 (130 feet) were in the arthroplasty group, while the other 108 (139 feet) were in the arthrodesis group. The results of meta-analysis showed that the arthrodesis group was superior to the arthroplasty group in the footwear (MD=−0.88, 95%CI −1.55 to −0.22, P=0.01), and the alignment (MD=−5.04, 95%CI −8.94 to −1.14, P lt;0.000 01) with significant differences. But there were no significant differences between the two groups in patient satisfaction, metastatic lesions, pain, activity and weight-bearing of Hallux.
Conclusion Based on the current studies, arthrodesis is superior to arthroplasty in treating rheumatoid forefoot deformity. For the quality restrictions and possible publication bias of the included studies, more double blind, high quality RCTs are required to further evaluate the effects.
