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.

Cross-sectional Anatomy of the Ilium: Implications for Acetabular Component Placement in Total Hip Arthroplasty

John Antoniades MD, Vincent D. Pellegrini MD

High hip center reconstructions, used in revision and complex primary THAs, rely on pelvic bone stock at least 35 mm above the anatomic teardrop. However, the technique does not restore normal hip biomechanics and controversy exists regarding acetabular implant survival. Previous reports document a wide range of implant positioning above the teardrop. There is no anatomic guidance in the literature regarding the amount of bone stock available for initial implant stability in this area of the ilium.
