The 2015 Frank Stinchfield Award: Radiographic Abnormalities Common in Senior Athletes With Well-functioning Hips but Not Associated With Osteoarthritis

Lucas A. Anderson MD, Mike B. Anderson MSc, Ashley Kapron PhD, Stephen K. Aoki MD, Jill A. Erickson PA-C, Jesse Chrastil MD, Ramon Grijalva MD, Christopher Peters MD

It is not known whether morphological abnormalities of the hip are compatible with lifelong hip function and avoidance of osteoarthritis (OA). Our purpose was to investigate the prevalence of radiographic findings consistent with femoroacetabular impingement (FAI) and dysplasia (DDH) in senior athletes with well-functioning hips.

Ceramic-on-ceramic THA Associated With Fewer Dislocations and Less Muscle Degeneration by Preserving Muscle Progenitors

Philippe Hernigou MD, Xavier Roussignol MD, Jerome Delambre MD, Alexandre Poignard MD, Charles-Henri Flouzat-Lachaniette MD

Dislocation is a common complication after total hip arthroplasty (THA). Although the etiology of dislocation is multifactorial, longer-term changes in muscle such as atrophy may influence the risk of prosthetic dislocation. Biological differences in wear products generated by different bearing surfaces may influence differences in the appearance of periarticular muscle after THA; however, such bearing-associated differences to our knowledge have not been studied in vivo, and few studies have evaluated bearing-associated differences in dislocation risk.

Primary Ceramic-on-ceramic Total Hip Arthroplasty Using a 32-mm Ceramic Head With a Titanium-alloy Sleeve

Seung-Jae Lim MD, Seung-Pil Jang MD, Dong-Wook Kim MD, Young-Wan Moon MD, Youn-Soo Park MD

Modern ceramic-on-ceramic bearings have become attractive alternatives to conventional polyethylene in total hip arthroplasty (THA) as a result of their low wear and minimal particle production. However, 28-mm heads in ceramic-on-ceramic bearing couples have been associated with ceramic fracture. To address these issues, 32-mm and larger ceramic heads with a titanium-alloy sleeve have been introduced, although limited data are available on their durability and clinical outcomes.

Does Native Combined Anteversion Influence Pain Onset in Patients With Dysplastic Hips?

Yusuke Kohno MD, Yasuharu Nakashima MD, PhD, Mio Akiyama MD, PhD, Masanori Fujii MD, PhD, Yukihide Iwamoto MD, PhD

Combined anteversion is the sum of femoral and acetabular anteversion and represents their morphological relationship in the axial plane. Few studies have investigated the native combined anteversion in patients with symptomatic dysplastic hips.

High Survivorship With Cementless Stems and Cortical Strut Allografts for Large Femoral Bone Defects in Revision THA

Young-Hoo Kim MD, Jang-Won Park MD, Jun-Shik Kim MD, Devarshi Rastogi MD

Numerous studies have investigated the clinical and radiographic results of revision THAs with use of cementless stems and cortical strut allografts. However, to our knowledge, no long-term followup studies have evaluated patients undergoing revision THA with use of cortical strut allografts where the allografts provided the primary stability for extensively coated femoral stems in the presence of extensive femoral diaphyseal bone defects.

John Charnley Award: Preoperative Patient-reported Outcome Measures Predict Clinically Meaningful Improvement in Function After THA

Jonathan L. Berliner MD, Dane J. Brodke BA, Vanessa Chan MPH, Nelson F. SooHoo MD, Kevin J. Bozic MD, MBA

Despite the overall effectiveness of total hip arthroplasty (THA), a subset of patients remain dissatisfied with their results because of persistent pain or functional limitations. It is therefore important to develop predictive tools capable of identifying patients at risk for poor outcomes before surgery.

Frequent Femoral Neck Osteolysis With Birmingham Mid-head Resection Resurfacing Arthroplasty in Young Patients

Asaad Asaad MD, MSc, Alister Hart MA, MD, Michael M. Y. Khoo BSc, MBBS, Kevin Ilo BSc, Gavin Schaller BSc, Jonathan D. J. Black MBBS, MSc, Sarah Muirhead-Allwood BSc, MBBS

Mid-head resection total hip resurfacing arthroplasty was promoted as an alternative to traditional total hip resurfacing for patients with poor femoral head bone quality or abnormal femoral head morphology, because those patients are at high risk of failure with traditional total hip resurfacing. It is a large-headed metal-on-metal device that uses a short, bone-conserving stem. Good performance of the implant has been reported at short-term followup, but no information on the implant performance in the mid- or long-term is available.

Does Arthroplasty Provide Better Outcomes Than Internal Fixation At Mid- and Long-term Followup? A Meta-analysis

Jin Jiang MD, PhD, Chen-hui Yang MD, Qiao Lin MD, Xiang-dong Yun MD, PhD, Ya-yi Xia MD, PhD

Arthroplasty has been shown to be superior regarding low risk of reoperation and better function score to internal fixation for treatment of displaced femoral neck fractures at short-term followup. However, there are unanswered questions regarding the efficacy of arthroplasty in the longer term compared with internal fixation.

Complications of Total Hip Arthroplasty: Standardized List, Definitions, and Stratification Developed by The Hip Society

William L. Healy MD, Richard Iorio MD, Andrew J. Clair MD, Vincent D. Pellegrini MD, Craig J. Della Valle MD, Keith R. Berend MD

Reporting of complications after total hip arthroplasty (THA) is not standardized, and it is done inconsistently across various studies on the topic. Advantages of standardizing complications include improved patient safety and outcomes and better reporting in comparative studies.

Intraoperative Synovial C-reactive Protein Is as Useful as Frozen Section to Detect Periprosthetic Hip Infection

Martin A. Buttaro MD, Gabriel Martorell MD, Mauricio Quinteros MD, Fernando Comba MD, Gerardo Zanotti MD, Francisco Piccaluga MD

Synovial quantification of C-reactive protein (SCRP) has been recently published with high sensitivity and specificity in the diagnosis of periprosthetic joint infection. However, to our knowledge, no studies have compared the use of this test with intraoperative frozen section, which is considered by many to be the best intraoperative test now available.
