AB  - Objective: To review the clinical performance of the anatomic medullary locking (AML) femoral stem in total hip arthroplasty.Design: A clinical and radiographic review.Setting: A tertiary lower limb joint replacement centre.Patients: Two hundred and twenty-one patients with noninflammatory gonarthrosis.Interventions: Two hundred and twenty-seven primary total hip arthroplasties with the noncemented AML component completed by two surgeons.Main Outcome Measures: Independent review by two experienced reviewers of the postoperative Harris hip score, radiographs of component fixation, size and degree of diaphyseal fill.Results: Harris hip score was 84 (range from 43 to 98); component fixation showed bone ingrowth in 41%, stable fixation with fibrous ingrowth in 56% and unstable fixation in 3%; severe thigh pain in 4% of cases correlated with unstable fixation, and there was mild thigh pain in 20% of cases.Conclusion: The AML femoral stem performs well in replacement arthroplasty compared with other noncemented stems.
