“…The longer the observation time, the more important the amount of polyethylene wear becomes, irrespective of body-weight and the level of activity. 13 In our series wear of the cup was not seen at the ten-year follow-up, 6 but became apparent in ten of the 42 prostheses (24%) by 15 years. 7 At 22 years, eight of the 20 prostheses (40%)…”

In the last decade many new designs of implant for total hip replacement (THR) have become available but those which perform well in laboratory testing often do poorly clinically.1 Some designs with good results at five years are associated with high rates of failure at ten years. (Table I). We now report the results of the 22-year followup. No patient was lost to follow-up.Their mean age at the time of primary THR was 70.2 (40 to 93) years (Fig. 1). The preoperative diagnosis was osteoarthritis in 117 hips (80%), fracture of the femoral neck in 15 (10%), rheumatoid arthritis in 8 (6%) and congenital dysplasia in 6 (4%). The details of the procedure were as previously reported by Van der Schaat et al 6 andAlsema et al. 7 We used a Stanmore CoCrMo alloy prosthesis in all except six hips which had a titanium (Ti6Al-4V(IM1318)) femoral stem because of proven sensitivity to metal. In all cases a relatively small straight or slightly curved femoral stem, mark 7, was used which has a socalled satin surface finish and a roughness of 15 to 20 microns. A 25 mm head and an ultra-high-molecularweight polyethylene (UHMWP) cup were used in all cases. The acetabular subchondral bone was preserved as much as possible. In the acetabulum three perforating keying holes were made. The femoral canal was not plugged. A cement gun was used, but without pressurisation. The operations were performed by two orthopaedic surgeons (RD and TJM) using a posterolateral approach. In 1998 there were 21 surviving patients with a mean age of 85.7 years (75.3 to 95.1) and a mean follow-up of 22.2 years (21.8 to 23.3). We were able to establish if revision surgery had been required in the 114 patients who had died.

“…His concept »low friction arthroplasty« still enjoys long term success with Kaplan-Meier survival rates of 85-90% after 20 years [24,36,39,44]. Other cemented stem designs showed a wide range between poor [2,7,41,45,46] and good results [12,15,21,29,30,47] both clinically and radiographically. However, it soon became obvious that not only stem design but, in particular, operative and cementing technique had to be considered important factors influencing the outcome of cemented THA.…”

This chapter gives an overview of cementing technique evolution and defines the current status of modern cementing techniques. Modern cementing techniques aim to improve the mechanical interlock between bone and cement in order to establish a durable interface. The use of distal plug, cement gun, pulsatile lavage and cement pressurising devices have been shown to significantly improve long-term outcomes.
