Kryptonite is a non-toxic biologic polymer, that has previously been used in orthopedic surgery. The objective of our study is to demonstrate the benefits of Kryptonite in cardiac surgery patients at high risk for sternal wound complications. The investigators have designed a randomized clinical trial of 48 high risk patients, with a 1:2 randomization of kryptonite to conventional closure. The primary outcome will be quality of life. Secondary outcomes include sternal complications, pain, hospital length of stay, and respiratory function.

    3. Limited mobility with dependence on upper body for mobilization.

Exclusion Criteria:

  • age <18 years
  • cardiac surgery through incision other than sternotomy
  • emergent surgery
  • previous sternotomy (i.e. redo cardiac surgery)
  • surgery for sternal dehiscence or mediastinitis, and
  • inability to obtain informed consent
