Do Activity Levels Increase After Total Hip and Knee Arthroplasty?

Paula Harding D Clin Physio, Anne E. Holland PhD, Clare Delany PhD, Rana S. Hinman PhD

People with osteoarthritis (OA) often are physically inactive. Surgical treatment including total hip arthroplasty or total knee arthroplasty can substantially improve pain, physical function, and quality of life. However, their impact on physical activity levels is less clear.

Development of a Valid Simplified Chinese Version of the Oxford Hip Score in Patients With Hip Osteoarthritis

Wei Zheng MD, Jia Li MD, Jinzhu Zhao MD, Denghui Liu MD, Weidong Xu MD

Although the Oxford Hip Score has been translated and validated in several languages, there is currently no Chinese version of the outcomes measurement. Our study aims to crossculturally adapt and validate the Oxford Hip Score into a simplified Chinese version.

Risk of Impingement and Third-body Abrasion With 28-mm Metal-on-metal Bearings

Ian C. Clarke PhD, Jean-Yves Lazennec MD, Adrien Brusson MSc, Christina Savisaar PhD, John G. Bowsher PhD, Michelle Burgett BA, Thomas K. Donaldson MD

Concerns have been raised about the sequelae of metal-on-metal (MoM) bearings in total hip arthroplasty (THA). However, retrieval studies, which offer the best insight into the clinically relevant mechanisms of MoM wear, have followed predictable trends to date such as indicting cobalt-chromium (CoCr) metallurgy, cup design, high conformity between the head and cup, “steep cups,” “microseparation,” and “edge wear.”

Developing a Pathway for High-value, Patient-centered Total Joint Arthroplasty

Aricca D. Van Citters MS, Cheryl Fahlman PhD, Donald A. Goldmann MD, Jay R. Lieberman MD, Karl M. Koenig MD, MS, Anthony M. DiGioia MD, Beth O’Donnell MPH, John Martin MPH, Frank A. Federico RPh, Richard A. Bankowitz MD, Eugene C. Nelson DSc, MPH, Kevin J. Bozic MD, MBA

Total joint arthroplasty (TJA) is one of the most widely performed elective procedures; however, there are wide variations in cost and quality among facilities where the procedure is performed.

Is L2 Paravertebral Block Comparable to Lumbar Plexus Block for Postoperative Analgesia After Total Hip Arthroplasty?

Richa Wardhan MD, Anne-Sophie M. Auroux PharmD, Bruce Ben-David MD, Jacques E. Chelly MD, PhD, MBA

Continuous lumbar plexus block (LPB) is a well-accepted technique for regional analgesia after THA. However, many patients experience considerable quadriceps motor weakness with this technique, thus impairing their ability to achieve their physical therapy goals.

What is the Prognosis of Revision Total Hip Arthroplasty in Patients 55 Years and Younger?

Muyibat A. Adelani MD, Karla Crook BS, Robert L. Barrack MD, William J. Maloney MD, John C. Clohisy MD

Revision THAs are expected to increase; however, few studies have characterized the prognosis of revision THAs in younger patients.

Modular versus Nonmodular Neck Femoral Implants in Primary Total Hip Arthroplasty: Which is Better?

Paul J. Duwelius MD, Bob Burkhart PA, Clay Carnahan PA, Grant Branam BSc, Laura Matsen Ko MD, YingXing Wu MD, Cecily Froemke MS, Lian Wang MS, Gary Grunkemeier PhD

Restoration of the hip center is considered important for a successful THA and requires achieving the right combination of offset, anteversion, and limb length. Modular femoral neck designs were introduced to make achieving this combination easier. No previous studies have compared these designs in primary THA, and there is increasing concern that modular designs may have a higher complication rate than their nonmodular counterparts.

Symptomatic Pulmonary Embolus After Joint Arthroplasty: Stratification of Risk Factors

Javad Parvizi MD, Ronald Huang MD, Ibrahim J. Raphael MD, William V. Arnold MD, PhD, Richard H. Rothman MD, PhD

Prophylaxis for pulmonary embolism (PE) after total joint arthroplasty (TJA) presents the clinical dilemma of balancing the risk of postoperative thrombotic risk and anticoagulation-related complications such as bleeding, hematoma formation, and infection. Risk stratification of patients undergoing TJA is needed to tailor prophylaxis based on thrombotic and bleeding risk.

Long-term Results and Bone Remodeling After THA With a Short, Metaphyseal-fitting Anatomic Cementless Stem

Young-Hoo Kim MD, Jang-Won Park MD, Jun-Shik Kim MD, Jun-Seok Kang MD

Long-term results of standard total hip arthroplasty (THA) in young patients were not optimal. There are a number of reported disadvantages to longer cementless stems in THA including thigh pain and proximal stress shielding. However, it is unknown whether a short, metaphyseal-fitting anatomic stem without diaphyseal fixation, which represents a possible alternative, will maintain fixation over the longer term.

Efficacy of Revision Surgery for the Dislocating Total Hip Arthroplasty: Report From a Large Community Registry

Tiare Salassa MD, Daniel Hoeffel MD, Susan Mehle BS, Penny Tatman MPH, Terence J. Gioe MD

Historically, achieving stability for the unstable total hip arthroplasty (THA) with revision surgery has been achieved inconsistently. Most of what we know about this topic comes from reports of high-volume surgeons’ results; the degree to which these results are achieved in the community is largely unknown, but insofar as most joint replacements are done by community surgeons, the issue is important.
