Underlying diagnosis predicts patient-reported outcomes after revision total knee arthroplasty.

ABSTRACT:

Objective

To assess the association of underlying diagnosis with outcomes after revision total knee arthroplasty (TKA).

Methods

For this cohort study we used prospectively collected data from the Mayo Clinic Total Joint Registry on all revision TKA patients from 1993 to 2005 with 2- or 5-year response to a validated knee questionnaire that assesses pain and function. We used logistic regression to assess the odds of moderate-severe activities of daily living (ADL) limitations and moderate-severe index knee pain 2 and 5 years after revision TKA. Odds ratios (ORs) and 95% CIs are presented.

Results

The underlying diagnosis for the 2- and 5-year cohorts was loosening, wear or osteolysis in 73% and 75%; dislocation, bone or prosthesis fracture, instability or non-union in
