Veterans With Diabetes Receive Arthroplasty More Frequently and at a Younger Age

Karen B. King PhD, Thomas W. Findley MD, PhD, Allison E. Williams RN, ND, PhD, Allan L. Bucknell MD

A future increase in total joint arthroplasties in patients with diabetes seems likely considering the prevalence of osteoarthritis and diabetes mellitus are increasing. However, the rates of arthroplasty in the population of patients with diabetes are unclear.

The Chitranjan Ranawat Award: Should Prophylactic Antibiotics Be Withheld Before Revision Surgery to Obtain Appropriate Cultures?

Matthew W. Tetreault BA, Nathan G. Wetters MD, Vinay Aggarwal BS, Michael Mont MD, Javad Parvizi MD, FRCS, Craig J. Della Valle MD

Preoperative antibiotics are known to be critical for decreasing the risk of periprosthetic joint infection (PJI) in primary THA and TKA. However, antibiotics often are withheld before revision surgery, as there is concern that even a single dose of prophylactic antibiotics may affect intraoperative cultures.

Impact of Socioeconomic Factors on Outcome of Total Knee Arthroplasty

Robert L. Barrack MD, Erin L. Ruh MS, Jiajing Chen MPH, Adolph V. Lombardi MD, Keith R. Berend MD, Javad Parvizi MD, FRCS, Craig J. Della Valle MD, William G. Hamilton MD, Ryan M. Nunley MD

Few data exist regarding the impact of socioeconomic factors on results of current TKA in young patients. Predictors of TKA outcomes have focused primarily on surgical technique, implant details, and individual patient clinical factors. The relative importance of these factors compared to patient socioeconomic status is not known.

Posterior Condylar Offset Does Not Correlate With Knee Flexion After TKA

Yoshinori Ishii MD, Hideo Noguchi MD, Mitsuhiro Takeda MD, Junko Sato MD, Shin-ichi Toyabe MD

Studies of medial and lateral femoral posterior condylar offset have disagreed on whether posterior condylar offset affects maximum knee flexion angle after TKA.

Patient-specific Guides Do Not Improve Accuracy in Total Knee Arthroplasty: A Prospective Randomized Controlled Trial

Jan Victor MD, PhD, Jan Dujardin MD, Hilde Vandenneucker MD, Nele Arnout MD, Johan Bellemans MD, PhD

Recently, patient-specific guides (PSGs) have been introduced, claiming a significant improvement in accuracy and reproducibility of component positioning in TKA. Despite intensive marketing by the manufacturers, this claim has not yet been confirmed in a controlled prospective trial.

Older Age Increases Short-term Surgical Complications After Primary Knee Arthroplasty

Molly C. Easterlin BA, Douglas G. Chang MD, PhD, Mark Talamini MD, David C. Chang PhD, MPH, MBA

Age is a known risk factor for complications after knee arthroplasty; however, age-related risks for a variety of complications of total and partial knee arthroplasties have not been well quantified.

Unicondylar Arthroplasty in Knees With Deficient Anterior Cruciate Ligaments

Gerard A. Engh MD, Deborah J. Ammeen BS

Historically, a functional ACL has been a prerequisite for patients undergoing unicondylar knee arthroplasty (UKA). However, this premise has not been rigorously tested.

Stratification of Standardized TKA Complications and Adverse Events: A Brief Communication

Richard Iorio MD, Craig J. Della Valle MD, William L. Healy MD, Keith R. Berend MD, Fred D. Cushner MD, David F. Dalury MD, Jess H. Lonner MD

The Total Knee Arthroplasty (TKA) Complications Workgroup of the Knee Society developed a standardized list and definitions of complications associated with TKA. Twenty-two complications and adverse events believed important for reporting outcomes of TKA were identified. The Editorial Board of , the Executive Board of the Knee Society, and the members of the Knee Society TKA Complications Workgroup came to the conclusion that reporting of a list of TKA adverse events and complications would be more valuable if they were stratified using a validated classification system.

Consensus Statement from the Consensus Conference on Bilateral Total Knee Arthroplasty Group

Stavros G. Memtsoudis MD, PhD, Mary Hargett BS, Linda A. Russell MD, Javad Parvizi MD, William L. Cats-Baril PhD, Ottokar Stundner MD, Thomas P. Sculco MD

Controversy exists regarding many aspects of decision making pertaining to same-day versus staged bilateral TKA (BTKAs), including patient selection, perioperative management decisions, and other important choices.

Better Quality of Life After Medial Versus Lateral Unicondylar Knee Arthroplasty

Thoralf R. Liebs MD, Wolfgang Herzberg MD

The number of unicompartmental knee arthroplasties (UKAs) is growing worldwide. Because lateral UKAs are performed much less frequently than medial UKAs, the limited information leaves unclear whether UKAs have comparable survival and health-related quality of life (HRQoL) of the lateral UKA to medial UKAs.
