Revisions
dislocation
No patients in the CLTP group had revision surgery during the 5-year follow-up. One patient in the CTP group was revised to TKR between 2- and 5-year follow-up due to aseptic loosening of the tibial component. One patient in the CSP group was revised to TKR between 2- and 5-year follow-up due to bearing dislocation.
