failure is still substantial. It ranges from 1.8 to 11.1% ( 3 , 4 ) at midterm follow-up and up to 10.4–16.7% at long-term follow-up ( 5 ). The unambiguous and universally accepted definition of failure after ACL reconstruction is yet to be determined

Introduction Extensor mechanism failure is an uncommon but serious complication after primary or revision total knee arthroplasty (TKA). It is associated with significant morbidity and reduced quality of life due to extensor lag, instability

). Failure of ACL-R is defined by a history of previous primary ACL-R with a new onset of clinical symptoms such as instability and possibly giving way episodes. Additionally, positive Lachman and/or pivot shift tests are expected. The diagnosis of graft

History Arthroplasty became popular in the second half of the 20th century and has developed since then into one of the most successful fields in orthopaedics ( 1 ). This development was not free from problems and failures. The reduction of
