Continuous Adductor Canal Blocks Are Superior to Continuous Femoral Nerve Blocks in Promoting Early Ambulation After TKA

Seshadri C. Mudumbai MD, MS, T. Edward Kim MD, Steven K. Howard MD, J. Justin Workman MD, Nicholas Giori MD, Steven Woolson MD, Toni Ganaway BA, Robert King BS, Edward R. Mariano MD, MAS (Clinical Research)

Femoral continuous peripheral nerve blocks (CPNBs) provide effective analgesia after TKA but have been associated with quadriceps weakness and delayed ambulation. A promising alternative is adductor canal CPNB that delivers a primarily sensory blockade; however, the differential effects of these two techniques on functional outcomes after TKA are not well established.

Single-injection or Continuous Femoral Nerve Block for Total Knee Arthroplasty?

Eric Albrecht MD, DESA (Fellow), Dorothea Morfey BSc, MBBS, Vincent Chan MD, Rajiv Gandhi MD, Arkadiy Koshkin MD, Ki Jinn Chin MD, MBBS, Sylvie Robinson BSc, Philippe Frascarolo PhD, Richard Brull MD

The ideal local anesthetic regime for femoral nerve block that balances analgesia with mobility after total knee arthroplasty (TKA) remains undefined.

Does Adding Antibiotics to Cement Reduce the Need for Early Revision in Total Knee Arthroplasty?

Eric Bohm MD, MSc, FRCSC, Naisu Zhu MD, DrPH, Jing Gu MD, Nicole Guia MHSc, Cassandra Linton MSc, Tammy Anderson MSc, David Paton MSc, Michael Dunbar MD, FRCSC, PhD

There is considerable debate about whether antibiotic-loaded bone cement should be used for fixation of TKAs. While antibiotics offer the theoretical benefit of lowering early revision due to infection, they may weaken the cement and thus increase the likelihood of aseptic loosening, perhaps resulting in a higher revision rate.

Coronal Limb Alignment and Indications for High Tibial Osteotomy in Patients Undergoing Revision ACL Reconstruction

Ho Hyun Won MD, Chong Bum Chang MD, PhD, Min Soo Je MD, Moon Jong Chang MD, Tae Kyun Kim MD, PhD

Failed ACL reconstruction frequently is accompanied by irreparable medial meniscal tear and/or visible osteoarthritis (OA) in the medial tibiofemoral joint. Thus, assessment for the presence of varus malalignment is important in caring for patients in whom revision ACL reconstruction is considered.

Trabecular Metal in Total Knee Arthroplasty Associated with Higher Knee Scores: A Randomized Controlled Trial

Mariano Fernandez-Fairen MD, PhD, Daniel Hernández-Vaquero MD, PhD, Antonio Murcia MD, PhD, Ana Torres MD, PhD, Rafael Llopis MD, PhD

Porous tantalum is an option of cementless fixation for TKA, but there is no randomized comparison with a cemented implant in a mid-term followup.

The Oxford Unicompartmental Knee Fails at a High Rate in a High-volume Knee Practice

William C. Schroer MD, C. Lowry Barnes MD, Paul Diesfeld PA, Angela LeMarr RN, Rachel Ingrassia RN, Diane J. Morton MS, Mary Reedy RN

The Oxford knee is a unicompartmental implant featuring a mobile-bearing polyethylene component with excellent long-term survivorship results reported by the implant developers and early adopters. By contrast, other studies have reported higher revision rates in large academic practices and in national registries. Registry data have shown increased failure with this implant especially by lower-volume surgeons and institutions.

Continuous Femoral Nerve Block Using 0.125% Bupivacaine Does Not Prevent Early Ambulation After Total Knee Arthroplasty

Michael J. Beebe MD, Rachel Allen MD, Mike B. Anderson MS, ATC, Jeffrey D. Swenson MD, Christopher L. Peters MD

Continuous femoral nerve block has been shown to decrease opioid use, improve postoperative pain scores, and decrease length of stay. However, several studies have raised the concern that continuous femoral nerve block may delay patient ambulation and increase the risk of falls during the postoperative period.

Perioperative Morbidity and Mortality of Same-day Bilateral TKAs: Incidence and Risk Factors

Lazaros Poultsides MD, Stavros Memtsoudis MD, Alejandro Gonzalez Della Valle MD, Ivan De Martino MD, Huong T. Do MA, Michael Alexiades MD, Thomas Sculco MD

Controversy persists regarding the safety of same-day bilateral TKAs, and indications for same-day versus staged bilateral surgery need to be clarified.

Bariatric Orthopaedics: Total Knee Arthroplasty in Super-obese Patients (BMI > 50 kg/m2 ). Survivorship and Complications

Qais Naziri MD, Kimona Issa MD, Arthur L. Malkani MD, Peter M. Bonutti MD, Steven F. Harwin MD, Michael A. Mont MD

Some studies have suggested that patients who are super obese (BMI > 50 kg/m) may have poorer outcomes and more frequent complications when undergoing TKA compared with those who have lower BMI, however, the literature on this is scant.

Translation and Validation of the Dutch New Knee Society Scoring System©

Catherine Van Der Straeten MD, Erik Witvrouw PT, PhD, Tine Willems PT, PhD, Johan Bellemans MD, PhD, Jan Victor MD, PhD

A new version of The Knee Society Knee Scoring System(KSS) has recently been developed. Before this scale can be used in non-English-speaking populations, it has to be translated and validated for a particular population.
