The Knees

Knee-replacement surgery can be a painstaking process for both the patient and the surgeon. But rather than replacing an entire knee joint, ConforMIS has developed a procedure in which the joint can be scanned and "resurfaced," so that patient-specific problems can be addressed. Surgeons using the process can complete knee operations in 30 percent less time, the company says. With $80 million in funding, the Burlington, Massachusetts-based company also holds patents to apply the technology to the hip, ankle, and spine.
