Outcomes of Unicompartmental Knee Arthroplasty After Aseptic Revision to Total Knee Arthroplasty
نویسنده
چکیده
Methods: The study was based on 768 failed primary TKAs revised to TKAs (TKA/TKA) and 578 failed primary UKAs revised to TKAs (UKA/TKA) reported to the Norwegian Arthroplasty Register between 1994 and 2011. Patient-reported outcomemeasures (PROMs) including the EuroQol EQ-5D, the Knee Injury and Osteoarthritis Outcome Score (KOOS), and visual analog scales assessing satisfaction and pain were used.We performed Kaplan-Meier and Cox regression analyses adjusting for propensity score to assess the survival rate and the risk of re-revision andmultiple linear regression analyses to estimate the differences between the two groups in mean PROM scores.
