Does Age or Bilateral Disease Influence the Value of Hip Arthroplasty?

Bryan M. Lawless MD, Meridith Greene BA, James Slover MD, MS, Young-Min Kwon MD, PhD, Henrik Malchau MD, PhD

Measuring value in medicine is an increasingly important issue as healthcare spending continues to rise and cost containment becomes even more important. However, value assessments can be affected by patient factors and comorbidities.

Does Ipsilateral Knee Pain Improve after Hip Arthroplasty?

Wenbao Wang MD, Jeffrey A. Geller MD, Jonathan D. Nyce BS, Jung Keun Choi MD, William Macaulay MD

Intraarticular hip disease is commonly acknowledged as a cause of ipsilateral knee pain. However, this is based primarily on observational rather than high-quality evidence-based studies, and it is unclear whether ipsilateral knee pain improves when hip disease has been treated.

Surgical Technique: A Simple Soft-tissue-only Repair of the Capsule and External Rotators in Posterior-approach THA

James A. Browne MD, Mark W. Pagnano MD

Posterior soft tissue repair after posterior THA reportedly decreases the risk of dislocation. Previously described techniques often require drill holes through the greater trochanter, do not include both the short external rotators and the capsule, or require a complex series of multiple sutures. We therefore describe a technique to address these issues.

Incidence of Contralateral THA After Index THA for Osteoarthritis

Siraj A. Sayeed MD, Aaron J. Johnson MD, David E. Jaffe MD, Michael A. Mont MD

Currently more than 200,000 THAs are performed annually in the United States. In patients with bilateral disease, the chance of subsequent contralateral THA reportedly ranges from 16% to 85%. Factors influencing contralateral THA are not completely understood.

Overdiagnosis of Pulmonary Embolism: Evaluation of a Hypoxia Algorithm Designed to Avoid This Catastrophic Problem

Brian S. Winters MD, Mark Solarz MD, Christina L. Jacovides BS, James J. Purtill MD, Richard H. Rothman MD, PhD, Javad Parvizi MD, FRCS

We observed a substantial increase in the incidence of pulmonary embolism (PE) after total joint arthroplasty (TJA) when multidetector computerized tomography (MDCT) replaced ventilation-perfusion (V/Q) scans as the diagnostic modality of choice. We questioned whether this resulted from the detection of clinically unimportant PE with the more sensitive MDCT and in 2007 instituted a hypoxia protocol to enhance the detection of PE.

Can a Periarticular Levobupivacaine Injection Reduce Postoperative Opiate Consumption During Primary Hip Arthroplasty?

Terence P. Murphy MCh, Damien P. Byrne PhD, Paul Curtin MCh, Joseph F. Baker MCh, Kevin J. Mulhall FRCS (Tr and Orth)

Several reports have confirmed the ability of intraoperative periarticular injections to control pain after THA. However, these studies used differing combinations of analgesic agents and the contribution of each, including the local anesthetic agent, is uncertain. Understanding the independent effects of the various agents could assist in improved pain management after surgery.

Is an Algorithmic Approach to the Treatment of Recurrent Dislocation After THA Effective?

Ehsan Saadat MD, Glenn Diekmann MD, Steven Takemoto PhD, Michael D. Ries MD

The indications for surgical techniques for treatment of recurrent hip dislocation after THA differ, and their rates of achievement of stability may not be similar.

Bony Impingement Limits Design-related Increases in Hip Range of Motion

Adam Bunn BS, Clifford W. Colwell MD, Darryl D. D’Lima MD, PhD

Factors affecting risk for impingement and dislocation can be related to the patient, implant design, or surgeon. While these have been studied independently, the impact of each factor relative to the others is not known.

Aberrant Femoral Torsion Presenting with Frog-leg Squatting Mimicking Gluteal Muscle Contracture

Chia-Ling Chiang MD, Meng-Yuan Tsai MD, Wei-Ning Chang MD, Clement Kuen-Huang Chen MD

Patients with frog-leg squatting have restricted internal rotation and adduction of the affected hips during sitting or squatting. In the surgical literature, the cause generally has been presumed to arise from and be pathognomonic for gluteal muscle contracture. However, we have encountered patients with frog-leg squatting but without gluteal muscle contracture.

Multilevel Surgery Improves Gait in Spastic Hemiplegia But Does Not Resolve Hip Dysplasia

Erich Rutz MD, Elyse Passmore MEng, Richard Baker PhD, H. Kerr Graham MD

Multilevel orthopaedic surgery may improve gait in Type IV hemiplegia, but it is not known if proximal femoral osteotomy combined with adductor release as part of multilevel surgery in patients with hip dysplasia improves hip development.
