Union Rates Using Autologous Platelet Concentrate Alone and With Bone Graft in High-Risk Foot and Ankle Surgery Patients


Adjuvant use of autologous platelet concentrate (APC) to assist bone healing in foot and ankle surgery
has not been reported. This study examined the clinical results and complications after the adjuvant use
of APC in high-risk patients undergoing elective foot and ankle surgery. Patients at risk for bone-healing
complications were prospectively enrolled over a 6-month period for the intraoperative application of
APC. Patients were followed every 2 weeks for radiographic union and complications. Sixty-two high-risk
patients were enrolled, totaling 123 procedures. Mean patient age was 51 years (range, 16–76), there
were 36 females and 26 males, and 24 patients were smokers. Overall, a 94% union rate was achieved
at a mean of 41 days. For APC alone, the mean time to union was 40 days; when APC was used
with autograft, the mean time to union was 45 days (p D .173, two-tailed t test). These data suggest
that adjuvant APC results in an acceptable time to union and may be a useful adjunct to promote
osseous healing in high-risk patients undergoing elective foot and ankle surgery. (Journal of Surgical
