Woo and Morrey retrospectively analyzed 10,500 conventional THAs from the Mayo Clinic Total Joint Registry (1969–1978), using multivariate analysis to identify which preoperative, perioperative, and postoperative factors independently predict hip dislocation after arthroplasty.
This data supports choosing anterolateral over posterior approaches when possible and emphasizes the importance of trochanteric healing when osteotomy is performed. Previous hip surgery should flag patients as higher risk for dislocation during preoperative planning.
