title: The cementless PCA primary total hip system. Medium-term follow-up of 235 cases.
abstract: The Porous Coated total hip Arthroplasty (PCA), used by the authors since August 1984, represents a considerable advancement in the field of prosthetic replacement. Its original design and biological fixation give it long-lasting stability not only in young patients, but also patients with initial osteoporosis. Its use in cases of advanced osteoporosis, however, is more controversial. The 8-year results are quite satisfactory from both a clinical and radiographic standpoint, confirming, as other authors have reported, that the medium and long-term results of cementless total hip replacement tend to stabilize because there is a lack of late reactions, which are more common in cemented implants.
