Angled bearing inserts in total knee arthroplasty. A brief technical note.
Malalignment of total knee prosthetic components may lead to premature wear, loosening of components, or patellar instability. Unfortunately, removal of securely cemented or ingrown components is difficult and may be extremely destructive to the available bone stock. Angled bearing inserts provide a means to compensate for malpositioned components and should be considered an alternative to component removal in certain cases.
