I had ACL surgery 21 years ago. I guess the warranty was 20 yrs, cause now I need it again, together with a torn meniscus. I am getting that Sept 26. 21 years ago, it took a year to recover fully and 9 months of rehab. Anyone had this recently? Should I still expect to be on crutches for several months afterwards and 9 to 12 months rehab? Appreciate any insights to surgeries that were done in this Millennium.
