Early migration patterns of calcium phosphate versus hydroxyapatite-coated stem in uncemented total hip arthroplasty: a prospective randomized clinical trial using radiostereometric analysis

Early migration patterns of calcium phosphate versus hydroxyapatite-coated stem in uncemented total hip arthroplasty: a prospective randomized clinical trial using radiostereometric analysis

Abstract Background and purpose The design and coating of uncemented joint implants impact bone ingrowth and thereby the stability of the implant. This prospective randomized clinical trial aimed to compare early migration of two uncemented, similarly shaped femoral stems with either calcium phospha...
