Early clinical results with the hydroxyapatite-coated porous LSF Total Hip System.
The design of and early clinical results with the uncemented porous-coated LSF Anatomic and Midstem Total Hip Systems are described. In a Food and Drug Administration-approved program, a random selection method was used to determine which patients receive implants with a hydroxyapatite (HA) coating applied to the porous surface and which patients receive non-HA-coated implants. The early clinical results with the HA-coated systems appear superior to the non-HA-coated systems. A greater percentage of patients with HA systems have clinical scores in the excellent/good range, which is primarily a reflection of less prosthesis-related pain. Radiographically, all components appear well fixed with evidence of bone ingrowth. The HA-coated systems have a decreased incidence of radiolucencies, particularly in proximal zones.
