As I understand it, a liner replacement is the same as the surgery for a hip replacement. I have a liner that has worn down in the 5 years since the arthroplasty, and my Ortho advised urgency on removal/new liner, and said surgery and recovery time is basically same as a hip replacement. Not looking forward to it. Just had my other hip done 8 months ago. Lot of time off work. Good luck with yours, and hopefully, it will be covered by the company recalling the liner.
