Case Management: Total Joint Replacement Surgery

Many people today are more active than were previous generations, and they wish to remain so into old age. For younger patients, artificial joints must have excellent long-term durability to avoid the need for surgical revision later in life.<br><br>R.

According the American Academy of Orthopedic Surgeons, approximately 581,000 total knee replacements (TKR) are performed annually in the United States. More so than before, younger patients are requesting joint replacement to ease pain and improve quality of life. Cemented implants may not hold up in these cases, because biologic fixation (the growth of bone into and through the pores of the implant to secure it into place) does not occur. In contrast, cementless implants, which allow biologic fixation due to their porous nature, may last a lifetime. In a clinical study, porous tantalum has been found to have a higher porosity compared with other porous materials, and also demonstrates an increased material elasticity, which may preserve bone mineral density. This, along with other porous cementless materials, offers the promise of replacing cemented TKR as the gold standard.
