Karen L. Andrews, M.D., conducts research on the healing of chronic wounds, amputee rehabilitation, and impulse pumps to optimize perfusion and healing for patients who have wounds with decreased blood flow (ischemic wounds). She has also researched methods to enhance healing, including intermittent pneumatic compression and noncontact low-frequency ultrasound.
Dr. Andrews has been recognized within Mayo Clinic's Vascular Ulcer and Wound Healing Center for her use of provisional footwear, prescription footwear, custom bivalve ankle foot orthoses, rigid rockers and other devices to optimize healing of neuropathic wounds.
Prosthetic hip rehabilitation. Dr. Andrews and her team identified groups of patients who successfully use prostheses after hip-level amputations (hip disarticulations or hemipelvectomies). The team helps patients understand new advances in prosthetic components — such as microprocessor knee and Helix hip joints — and use their prostheses for primary mobility.
Dr. Andrews has also investigated the difference in functional outcome measures when patients walk with prostheses versus one-legged walking with crutches after hemipelvectomy.
The objectives of Dr. Andrews' research are to avoid amputation for people who are at risk and to optimize function after amputation when it is required. Her goal is to improve the quality of patients' lives while they're preparing for and healing from amputations and wounds.
