Twenty-two of 23 patients previously operated on with this scaffold were re-examined at a mean follow-up of 3.3 years (range 36\u201353 months). Overall, the results showed an unacceptably high rate of adverse tissue reactions related to the degradation process of the implant, resulting in a revision procedure in three patients. At final follow-up, at which point the implant had completely degraded, there were no signs of ongoing adverse tissue reactions. There was a significant decrease in pain, increase in strength and subjective improvement in function at final follow-up compared with the pre-operative results in patients who had not undergone revision surgery. However, owing to the high incidence of adverse tissue reactions, the use of the implant has been discontinued in the treatment of trapeziometacarpal osteoarthritis.<\/jats:p>\n
