THA: cementless acetabular components standard; femoral fixation cemented (elderly) vs cementless (younger). TKA: tibial components commonly cemented; cementless options increasing with porous coatings in the young. Cemented: immediate fixation, proven longevity; risks include cement implantation syndrome. Cementless: biologic ingrowth; risk of early micromotion if poor bone stock. Choice individualized by bone quality, age/activity, and surgeon expertise.
