Clinical Study Comparing Two Implant Surface Finishes in Patients Undergoing Cementless Total Hip Replacement

A Prospective, Randomized Study of Summit™ Porocoat® Versus Summit™ DuoFix™ HA in Cementless Total Hip Arthroplasty

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
