Final answer:
Linear wear rates of polyethylene greater than 0.1 mm per year are associated with implant failure in total hip arthroplasty.
Step-by-step explanation:
The linear wear rates of polyethylene that are associated with implant failure in total hip arthroplasty are generally greater than 0.1 mm per year.
When the wear rate exceeds this threshold, it can lead to increased friction and wear between the components of the hip replacement, causing the implant to fail prematurely.
This wear rate is important to monitor and manage to ensure the longevity and success of the hip arthroplasty procedure.
