The 2012 John Charnley Award: Clinical Multicenter Studies of the Wear Performance of Highly Crosslinked Remelted Polyethylene in THA

Charles R. Bragdon PhD, Michael Doerner BS, John Martell MD, Bryan Jarrett BS, Henrik Palm MD, Henrik Malchau MD, PhD

Highly crosslinked polyethylene (HXLPE) in THA was developed to reduce particle-induced periprosthetic osteolysis. A series of clinical studies were initiated to determine the clinical efficacy as judged by patient-reported scores, radiographic osteolysis, and wear analysis of one form of HXLPE.

Outcomes of Minimally Invasive Anterolateral THA Are Not Superior to Those of Minimally Invasive Direct Lateral and Posterolateral THA

Nelson V. Greidanus MD, MPH, Samir Chihab MD, Donald S. Garbuz MD, MHSc, Bassam A. Masri MD, Michael Tanzer MD, Allan E. Gross MD, Clive P. Duncan MD, MSc

There has been considerable interest in minimally invasive surgical (MIS) THA in recent years. The MIS anterolateral approach, or the MIS Watson-Jones approach, is a novel intermuscular abductor-sparing technique. Early reports from case series suggest the potential for superior function and reduced complications; however, the available information from clinical reports is inadequate to suggest surgeons should change from their accepted standard approach.

Prevalence and Treatment of Intraarticular Pathology Recognized at the Time of Periacetabular Osteotomy for the Dysplastic Hip

John G. Ginnetti MD, Christopher E. Pelt MD, Jill A. Erickson PA-C, Christin Dine PA-C, Christopher L. Peters MD

The indication for hip arthrotomy accompanied by intraarticular work during periacetabular osteotomy (PAO) has not been precisely defined. To validate a role for routine hip arthrotomy accompanied by intraarticular work, frequent intraarticular pathology must exist, and the adjunct procedures must not be associated with inferior relief of pain, reduced function, radiographic osteoarthritis progression, or conversion to THA.

Can the Alpha Angle Assessment of Cam Impingement Predict Acetabular Cartilage Delamination?

Paul E. Beaulé MD, FRCSC, Kelly Hynes MD, Gillian Parker BSc, Kyle A. Kemp MSc

Substantial acetabular cartilage damage is commonly present in patients suffering from femoral acetabular impingement (FAI). A better understanding of which patient is at risk of developing substantial cartilage damage is critical for establishing appropriate treatment guidelines.

Less Invasive Rotational Acetabular Osteotomy for Hip Dysplasia

Masaaki Maruyama MD, PhD, Shinji Wakabayashi MD, PhD, Keiji Tensho MD

Broad dissection with a long skin incision and detachment of the gluteus medius muscle performed for rotational acetabular osteotomy (RAO) can result in weakness in abduction strength of the hip. We use a surgical procedure for RAO that minimizes operative invasion of soft tissue and reduces incision length compared with conventional procedures.

Two-stage Treatment of Hip Periprosthetic Joint Infection Is Associated With a High Rate of Infection Control but High Mortality

Keith R. Berend MD, Adolph V. Lombardi MD, Michael J. Morris MD, Adam G. Bergeson MD, Joanne B. Adams BFA, Michael A. Sneller BS

Periprosthetic infection after total hip arthroplasty (THA) is a devastating complication. Reported rates of infection control range from 80% to 95% but mortality rates associated with treatment of infected THA are also substantial and we suspect underreported.

Intraoperative Cartilage Degeneration Predicts Outcome 12 Months After Hip Arthroscopy

Thorlene Egerton PhD, Rana S. Hinman PhD, Amir Takla MPhy, Kim L. Bennell PhD, John O’Donnell FRACS

When considering arthroscopic surgery for treatment of hip pain, it is important to understand the influence of joint degeneration on the likelihood of success. Previous research has shown poorer outcomes among patients with osteoarthritis but new arthroscopic techniques including femoroacetabular impingement correction and microfracture may lead to better arthroscopic outcomes.

Pelvic Tilt Is Minimally Changed by Total Hip Arthroplasty

William S. Murphy, Greg Klingenstein MD, Stephen B. Murphy MD, Guoyan Zheng PhD

While surgical navigation offers the opportunity to accurately place an acetabular component, questions remain as to the best goal for acetabular component positioning in individual patients. Overall functional orientation of the pelvis after surgery is one of the most important variables for the surgeon to consider when determining the proper goal for acetabular component orientation.

Physical Activity Level Improves After Periacetabular Osteotomy for the Treatment of Symptomatic Hip Dysplasia

Eduardo N. Novais MD, Benton Heyworth MD, Kerri Murray MPH, Victor M. Johnson MA, Young-Jo Kim MD, PhD, Michael B. Millis MD

Hip pain secondary to acetabular dysplasia can prevent participation in recreational activities.
