The authors performed a complication-based analysis of total knee (TKA), total hip (THA), and total ankle arthroplasty (TAA) using worldwide arthroplasty registers. We extracted data with respect to reason for revision surgery and pooled causes. The most common causes for revisions in THA were aseptic loosening (55.2%), dislocation (11.8 %), septic loosening (7.5%), periprosthetic fractures (6%), and others. The most common causes in TKA were aseptic loosening (29.8%), septic loosening (14.8%), pain (9.5%), wear (8.2%), and others. The most common causes in TAA were aseptic loosening (38%), technical errors (15%), pain (12%), septic loosening (9.8%), and others. Revisions in TKA and THA differ with respect to type of complication. However, in case of TAA, higher rates of technically related complications are reported.
