ABSTRACT
[Objective]To evaluate the clinical and radiological results of a curettage of granulation tissue,the exchange of polyethylene liner and morselized bone grafting for the treatment of osteolysis around a stable cementless acetabular cup.[Method]From Apr.1996 to Jul.2000,26 patients underwent revision of curettage of granulation tissue,the exchange of polyethylene liner and morselized allografting,which were followed up for an average of 5.5 years.The Harris Hip Score was used to evaluate the clinical result.The size of osteolysis of periacetabular cup was measured in AP and lateral view of X-rays.The allograft union was evaluated with the bone graft incorporation scale.[Result]Clinically,the average HHS increased from 82 to 88 points postoperatively.Radiologically,the size of osteolysis of peraacetabular cup changed from average 23.8 mm?24.9 mm to 11.5 mm?8.2 mm in the AP view,and from 11.1 mm?11.6 mm to 5.3 mm?4.5 mm in the lateral view.The bone graft incorporation scales were Grade Ⅰ and Ⅱ in 12 and 14 cases,respectively.[Conclusion]The Curettage of granulation tissues,morselized bone grafting and exchange of polyethylene liner and femoral head is an effective therapy in osteolysis around a stable cementless acetabular cup and could preserve the bone stock for the further revision THA.
