“…Our postoperative fracture incidence of 1.9% also compares favorably with published series of fractures around cementless femoral implants reporting rates of less than 1% to more than 10% [4,[10][11][12][13]15]. We found three patterns of postoperative fractures: pseudo A TL /new B 2 (n = 9), B 1 (n = 9), and C (n = 2).…”

Background Periprosthetic fractures can occur both intraoperatively and postoperatively with implantation of cementless tapered stems. Questions/purposes In a large cohort of patients receiving cementless, proximally hydroxyapatite-coated femoral implants, we answered the following questions: What was the incidence of intraoperative and postoperative fractures associated with the implant? What were the fracture patterns as classified by the Vancouver classification system? Did the Vancouver classification represent the fracture patterns found? How were the fractures treated and what were the treatment outcomes; that is, how many fractures healed and did the stems osseointegrate? Methods We evaluated 1039 hips (932 patients) from three prospective studies. The hips were divided into three groups: no fractures, intraoperative fractures, and postoperative fractures. Demographic differences among the groups were noted. Postoperative fractures were classified using the Vancouver classification system. We judged stem stability using Engh's criteria and fracture union was determined by the treating surgeon and confirmed by the authors. Results We identified 58 periprosthetic fractures in the 1039 hips (5.6%): 38 intraoperative (3.7%) and 20 postoperative (1.9%). Eleven of the postoperative fractures were classifiable by the original Vancouver classification system and nine were of the newly described ''clamshell'' variety, not classifiable by this system. No intraoperative fractures extended below the lesser trochanter. Twenty-five of these fractures were treated with a single cable or cerclage wire. The remaining received no specific treatment. Of the 20 postoperative fractures, five were treated nonoperatively. All stems osseointegrated. Conclusions Both intraoperative and postoperative fractures can be managed with success when the stem is

“…The reported frequency of fracture around cementless proximally fixed stems is between 0.4% and 11%, and for the most part, those data derive from small studies (100-436 patients) [4,[10][11][12][13]15]. The much larger national registries focus on primarily cemented femoral implants, reporting fracture frequencies of 0.4% to 2.5% [2,8].…”

“…It is a very annoying noise, similar to one emitted from a nonlubricated hinge, and has been reported not only with ceramic-on-ceramic but also with metal-on-metal bearings. The incidence of squeaking varies considerably, ranging from less than 1% to 20% [43][44][45]. In a recent prospective observational study on 1,486 ceramicon-ceramic total hip arthroplasties, 6% of the hips developed squeaking but just nine patients required revision surgery [46].…”

Alumina-on-alumina bearings in total hip arthroplasty have been developed in an attempt to minimise debris and the occurrence of osteolytic lesions. The outstanding tribological properties of this bearing system are explained by low surface roughness, high hardness for major scratch resistance, and high wettability. Since the 1970s, technological improvements in the manufacturing process of alumina components together with a better understanding of Morse taper technology have provided a surgical grade material with high density, high purity and small grains. Published studies on the outcome of total hip arthroplasty performed with this new generation of implants showed high survivorship especially in young and active patients, with survival rates free of revision of 90.8% to 97.4% at ten years. However, concern remains over ceramic liner fracture and squeaking, which has been noted recently with increasing prevalence. This review will discuss the current knowledge on the use of alumina-on-alumina bearings.

“…The first registry, CORRe, was established in 2003 by a group of arthroplasty surgeons at the Hospital for Special Surgery and is focused primarily on documenting intraoperative factors and device use [21]. This ongoing registry collects the UCLA score on patients at baseline and 2 years after surgery.…”

Background The University of California, Los Angeles (UCLA) activity scale and the Lower Extremity Activity Scale (LEAS) are the two most-widely used and rigorously developed scales for assessing activity level in patients having joint replacement. However, the two scales are not convertible, and the level of correlation between the two is not clear. Creating a crosswalk between these scales; that is, a concordance table to convert scores from one scale to the other and vice versa, will help compare results from existing studies using either scale, and pool those results for meta-analyses. It also will facilitate pooling data from multiple registries and data sources. Questions/Purpose To create a crosswalk between the UCLA and the LEAS activity scales for patients having THA or TKA. Methods Preoperative and 2-year postoperative UCLA and LEAS scores for a cohort of patients undergoing primary TKA or THA at the Hospital for Special Surgery between
