Hinged Knee Replacement

Wisconsin rates for HCPCS 27445

Replacement of the knee joint with an implant whose upper and lower halves are linked by a mechanical hinge. Because the implant itself controls how the knee bends, it is used when the ligaments that would normally hold the joint steady are absent or too damaged to do the job, or when a lot of bone has been lost.
