The Zimmer M/L Taper Hip Prosthesis with Kinectiv Technology is a system of modular stem and neck components designed to help the surgeon restore the natural hip joint center intraoperatively by addressing leg length, offset, and version independently.
The keystone to Kinectiv Technology is the exclusive use of +0 femoral heads. This allows independent adjustment of leg length and offset since all adjustments are made with the necks. Leg length is of primary concern in total joint replacement for surgeons and patients. Kinectiv Technology allows the surgeon to optimize leg length without affecting offset and conversely offset without affecting leg length.
With the exclusive use of the +0 head, every neck has been optimized to this head length to maximize range of motion. In addition, the ante/retroverted necks allow the surgeon to intraoperatively fine tune the range of motion depending on the patient anatomy and implant position.
