Radiographic assessment focused on implant migration and bone ingrowth, and clinical outcomes included survivorship, complications, the mobility score, and the Oxford Hip Score (OHS). The median follow-up was 7 years (range, 5 to 9 years). Thirty patients of diverse ethnic backgrounds (21 female; median age of 70 years) were included. Implant migration was limited to the first postoperative year (\u22645 mm), with negligible displacement thereafter. Bone ingrowth occurred in 27 (90%) of the patients. The 9-year implant survival rate was 96.3%, with 1 re-revision for infection. The median OHS improved from 8 preoperatively (interquartile range [IQR], 4 to 13) to 32 (IQR, 21 to 37) at the previous, mid-term follow-up (p &lt; 0.0001), and then remained essentially the same at the most recent follow-up. Mobility scores improved by a mean of 1.4 points (p &lt; 0.0001). Two dislocations (in 1 patient), 1 transient sciatic nerve palsy, and recurrent infection in 2 patients were recorded. CMAIs provide durable fixation. Constructs stabilize over time, reflecting osseointegration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>\n                      Therapeutic\n                      <jats:underline>Level IV<\/jats:underline>\n                      .
