Clinical Study Comparing Two Implant Surface Finishes in Patients Undergoing Cementless Total Hip Replacement
Clinical Study Comparing Two Implant Surface Finishes in Patients Undergoing Cementless Total Hip Replacement
Prospective, randomized study of Summit Porocoat versus Summit DuoFix HA in total hip
 arthroplasty
Hydroxyapatite (HA) is a bioactive ceramic that resembles the natural inorganic mineral
 content of bone, and as such is a highly osteoconductive material. The purpose of this study
 is to compare an HA coated and uncoated prosthesis.
Inclusion Criteria:

 -  Primary total hip replacement

 -  Patient age less than or equal to 75

 -  Sufficient bone stock to support prosthesis

 Exclusion Criteria:

 -  Previous hip replacement

 -  Significant angular/bony deformity

 -  Active joint sepsis

 -  Metal allergy

 -  Renal transplant

 -  Psychosocial disease

 -  Neurological disease/musculoskeletal disease that may affect weight-bearing
