FDA OKs Zimmer Mobile Bearing Knee

FDA yesterday approved Zimmer Holdings' NexGen LPS-Flex Mobile Knee, reports the Associated Press. The implant differs from most other artificial knees in the mobility it can offer. Zimmer said its product is designed to accommodate active deep flexion of up to 155 degrees for patients who are otherwise capable of that level of flexion, versus the 120 degrees of other implants. The knee can be implanted in a minimally invasive procedure.
