Is There a Benefit to Highly Crosslinked Polyethylene in Posterior-stabilized Total Knee Arthroplasty? A Randomized Trial

Paul F. Lachiewicz MD, Elizabeth S. Soileau BSN

Polyethylene wear and osteolysis remain a concern with the use of modular, fixed-bearing total knee arthroplasty (TKA). A variety of highly crosslinked polyethylenes (XLPs) have been introduced to address this problem, but there are few data on the results and complications of this polyethylene in posterior-stabilized knee prostheses.

Do Psychological Factors Predict Poor Outcome in Patients Undergoing TKA? A Systematic Review

Yasser Khatib MBBS, MSports Med, FRACS(Orth), Aman Madan BSc(Med), MBBS, Justine M. Naylor PhD, BAppSc(Phty), Ian A. Harris MBBS, MMed(Clin Epi), PhD, FRACS(Orth)

A subgroup of patients undergoing TKA is unhappy with the outcome of surgery and preoperative psychological factors may play a role in their dissatisfaction.

Bicruciate-retaining Total Knee Replacement Provides Satisfactory Function and Implant Survivorship at 23 Years

James W. Pritchett MD

One of the goals of a TKA is to approximate the function of a normal knee. Preserving the natural ligaments might provide a method of restoring close to normal function. Sacrifice of the ACL is common and practical during a TKA. However, this ligament is functional in more than 60% of patients undergoing a TKA and kinematic studies support the concept of bicruciate-retaining (that is, ACL-preserving) TKA; however, relatively few studies have evaluated patients treated with bicruciate-retaining TKA implants.

Recurrent Hemarthroses After TKA Treated With an Intraarticular Injection of Yttrium-90

Stephen Fine MBBCh, FRACS, Alex Klestov MBBS, BSc, FRACP

Recurrent hemarthroses after a TKA are uncommon and usually respond to nonoperative treatment or intervention using angiographic embolization or synovectomy. However, in rare circumstances, the problem can be resistant to treatment.

The Mark Coventry Award: Custom Cutting Guides Do Not Improve Total Knee Arthroplasty Clinical Outcomes at 2 Years Followup

Denis Nam MD, Andrew Park MD, Jeffrey B. Stambough MD, Staci R. Johnson Med, Ryan M. Nunley MD, Robert L. Barrack MD

Custom cutting guides (CCGs; sometimes called patient-specific instrumentation [PSI]) in total knee arthroplasty (TKA) use preoperative three-dimensional imaging to fabricate cutting blocks specific to a patient’s native anatomy.

Are There Sex Differences in Knee Cartilage Composition and Walking Mechanics in Healthy and Osteoarthritis Populations?

Deepak Kumar PT, PhD, Richard B. Souza PT, PhD, Karupppasamy Subburaj PhD, Toran D. MacLeod PT, PhD, Justin Singh BS, Nathaniel E. Calixto BS, Lorenzo Nardo MD, Thomas M. Link MD, Xiaojuan Li PhD, Nancy E. Lane MD, Sharmila Majumdar PhD

Women are at a greater risk for knee osteoarthritis (OA), but reasons for this greater risk in women are not well understood. It may be possible that differences in cartilage composition and walking mechanics are related to greater OA risk in women.

Functional Impairment Is a Risk Factor for Knee Replacement in the Multicenter Osteoarthritis Study

Barton L. Wise MD, MSc, Jingbo Niu DSc, David T. Felson MD, MPH, Jean Hietpas LCSW, Alesia Sadosky PhD, MPH, MBA, James Torner PhD, MS, Cora E. Lewis MD, MSPH, Michael Nevitt PhD, MPH

Debilitating pain associated with knee osteoarthritis (OA) often leads patients to seek and complete total knee arthroplasty (TKA). To date, few studies have evaluated the relation of functional impairment to the risk of TKA, despite the fact that OA is associated with functional impairment.

The Chitranjan Ranawat Award: Running Subcuticular Closure Enables the Most Robust Perfusion After TKA: A Randomized Clinical Trial

Cody C. Wyles BS, Steven R. Jacobson MD, Matthew T. Houdek MD, Dirk R. Larson MS, Michael J. Taunton MD, Franklin H. Sim MD, Rafael J. Sierra MD, Robert T. Trousdale MD

Maintaining robust perfusion is an important physiologic parameter in wound healing. The effect of different closure techniques on wound perfusion after total knee arthroplasty (TKA) has not been established previously and may have implications for wound healing.

What Is the Relationship Between Depressive Symptoms and Pain During Functional Tasks in Persons Undergoing TKA? A 6-year Perioperative Cohort Study

Daniel L. Riddle PT, PhD, Robert A. Perera PhD, William T. Nay PhD, Levent Dumenci PhD

Preoperative depressive symptoms have been shown in some but not all studies to be associated with poor self-reported pain and function outcomes. In addition, depressive symptoms after surgery have been shown to improve relative to preoperative levels.

Is Neuraxial Anesthesia Safe in Patients Undergoing Surgery for Treatment of Periprosthetic Joint Infection?

Mohammad R. Rasouli MD, Priscilla K. Cavanaugh MS, Camilo Restrepo MD, Hasan Huseyin Celyan MD, Mitchell G. Maltenfort PhD, Eugene R. Viscusi MD, Javad Parvizi MD

There is concern that neuraxial anesthesia in patients undergoing surgery for treatment of a periprosthetic joint infection (PJI) may increase the risk of having a central nervous system infection develop. However, the available data on this topic are limited and contradictory.
