This single-surgeon retrospective review asks whether second-generation cementing techniques could overcome the historically high femoral loosening rates seen in young THA patients. 50 cemented hips in 44 patients aged 50 or younger were followed to a mean of 12 years with no loss to follow-up. The paper also introduced the Barrack A-D femoral cement mantle grading system.
The 2% femoral loosening rate at 12 years in patients under 50 is the number that changed the field. Before this paper, first-generation cemented stems failed at 30-40% by 10 years in young patients, and many surgeons abandoned cement entirely for cementless implants. This paper reframed that conclusion: the problem was technique, not cement itself.
When you assess a cemented THA on the immediate postoperative film, use the Barrack grading system. Grade A or B is the target. A grade C or D result signals inadequate fixation and warrants close follow-up in any patient, but especially a young, active one.
The Barrack system was subsequently refined by Mulroy and Harris, who subdivided grade C into C1 (extensive radiolucent lines or voids) and C2 (cement mantle less than 1 mm or direct metal-cortical bone contact), adding granularity to the zone most predictive of late loosening.
The authors close with a direct challenge: cementless femoral fixation must now be benchmarked against this 2% failure rate, not the 30-40% of first-generation cement.
