Abstract

BACKGROUND:

Interposition arthroplasty with bioreplaceable poly-L/D-lactic acid (PLDLA) implants has been studied in Finland with promising results in reconstruction of the rheumatoid hand. We evaluated this material in a series of patients with rheumatoid forefoot deformities.

MATERIALS AND METHODS:

Thirty-five patients were randomized to either PLDLA metatarsophalangeal joint interposition arthroplasty group (16 patients) or to conventional metatarsal head resection group (19 patients).

RESULTS:

At 3 months after surgery, the function VAS was significantly better in the control group (p = 0.003). The difference disappeared by 12 months. Otherwise, comparison between the two groups did not reveal any statistically significant differences in the AOFAS scores or the pain VAS at 3 or 12 months.

CONCLUSION:

Early results after PLDLA interposition arthroplasty of metatarsophalangeal joints were not as promising as previously reported with rheumatoid metacarpophalangeal reconstruction.
