Charnley's 1970 study presents the first long-term histological examination of the bone-cement interface in humans, analyzing 23 retrieved specimens from one month to seven years post-implantation to determine how mechanical load is transmitted from acrylic cement to the femoral shaft.
This study established that bone cement integration occurs through fibrocartilage formation rather than direct bone-cement bonding, explaining the mechanical interface in cemented arthroplasty.
The absence of significant inflammatory response and presence of fat storage near cement surfaces supports the biocompatibility of acrylic cement in long-term implantation.
