Abstract
Instability/dislocation is a well-documented and recognized complication after primary and revision total hip arthroplasty (THA). Among available modern implant options, particular design characteristics may reduce the risk of dislocation and revision, such as big femoral head diameters (BTHA), dual mobility (DMTHA) acetabular components, and constrained liners (CTHA). This systematic review included eleven studies (nine comparative and two randomized controlled trials, 4084 patients). Postoperative dislocation and revision for any reason were compared. Network meta-analysis showed that the risk of revision and dislocation of DMTHA was significantly lower when compared to standard total hip arthroplasty (STHA). Based on short-term outcomes (0–5 years), the authors recommend using DMTHA and BTHA for safety.
