It was reported that a patient underwent an initial left total hip arthroplasty.One year post implantation, the head and stem were revised due to loosening of the femoral component with failure to osseointegrate.The patient was revised for a second time, five years post implantation due to fracture of the revision stem with complicated extraction via extended trochanteric osteotomy.After the second revision, the patient experienced recurrent dislocations requiring closed reduction under anesthesia.A third revision was planned but delayed due to difficulty extubating the patient and the concurrent onset bilateral pulmonary embolisms.After the patient¿s pulmonary function and anticoagulation measures were stabilized, the revision occurred during which, multiple hematomas were evacuated from the joint, and posterior instability was confirmed on exam.Upon replacing the acetabular shell, anteversion was increased by 15 degrees.A new constrained head and liner were placed within the shell, and the revision stem was retained.Postoperatively, the patient demonstrated slow but steady progress with intensive physical therapy.
