Translation and Cultural Adaptation of the Turkish Lysholm Knee Scale: Ease of Use, Validity, and Reliability

Derya Celik PT, PhD, Dilber Coşkunsu PT, MSc, Önder Kılıçoğlu MD, PhD

The Lysholm knee scale, first published in 1982, is an eight-item questionnaire designed to evaluate patients after knee ligament injury. However, as a tool developed in English, its use as a validated instrument has been limited to English-language populations.

Risk Factors for Early Revision After Primary TKA in Medicare Patients

Kevin J. Bozic MD, MBA, Edmund Lau MS, Kevin Ong PhD, Vanessa Chan MPH, Steven Kurtz PhD, Thomas P. Vail MD, Harry E. Rubash MD, Daniel J. Berry MD

Patient, surgeon, health system, and device factors are all known to influence outcomes in total knee arthroplasty (TKA). However, patient-related factors associated with an increased risk of early failure are not well understood, particularly in elderly patients.

Total Knee Arthroplasty After High Tibial Osteotomy: No Differences Between Medial and Lateral Osteotomy Approaches

Stephen Preston MDCM, James Howard MD, FRCSC, Douglas Naudie MD, FRCSC, Lyndsay Somerville PhD, James McAuley MD, FRCSC

High tibial osteotomy (HTO) has long been accepted as an effective treatment for unicompartmental osteoarthritis of the knee in young, active adults. For varus knees, the two most commonly performed valgus-producing HTOs are the lateral closing wedge and the medial opening wedge. Regardless of technique, some HTOs fail and are converted to TKA. To our knowledge, no studies have directly compared TKAs done after lateral closing-wedge osteotomies to those done after medial opening-wedge osteotomies.

The Mark Coventry Award: Higher Tissue Concentrations of Vancomycin With Low-dose Intraosseous Regional Versus Systemic Prophylaxis in TKA

Simon W. Young FRACS, Mei Zhang PhD, Joshua T. Freeman FRCPA, John Mutu-Grigg FRACS, Paul Pavlou FRCS, Grant A. Moore BSc (Hons)

In response to increasing antibiotic resistance, vancomycin has been proposed as an alternative prophylactic agent in TKA. However, vancomycin requires a prolonged administration time, risks promoting further antibiotic resistance, and can cause systemic toxicity. Intraosseous regional administration (IORA) is known to achieve markedly higher antibiotic concentrations than systemic administration and may allow the use of a lower vancomycin dose.

Intraarticular Fibrinogen Does Not Reduce Blood Loss in TKA: A Randomized Clinical Trial

Thomas Jan Heyse MD, Steven B. Haas MD, Denise Drinkwater BA, Stephen Lyman PhD, Han Jo Kim MD, Barbara A. Kahn BS, Mark P. Figgie MD

Bleeding remains an ongoing concern after total knee arthroplasty (TKA). Intraarticular application of human fibrinogen with a topical thrombin has been described to stop diffuse bleeding in knee arthroplasty.

Bundled Payments in Total Joint Arthroplasty: Targeting Opportunities for Quality Improvement and Cost Reduction

Kevin J. Bozic MD, MBA, Lorrayne Ward MBA, MPP, Thomas P. Vail MD, Mervyn Maze MB, ChB

Understanding the type and magnitude of services that patients receive postdischarge and the financial impact of readmissions is crucial to assessing the feasibility of accepting bundled payments.

Preemptive Low-dose Dexamethasone Reduces Postoperative Emesis and Pain After TKA: A Randomized Controlled Study

In Jun Koh MD, Chong Bum Chang MD, Jung Ha Lee MD, Young-Tae Jeon MD, Tae Kyun Kim MD

Dexamethasone is a potent analgesic and antiemetic. However, the benefit of dexamethasone after TKA is unclear, as is the efficacy in a current multimodal regime.

What Are the Rates and Causes of Hospital Readmission After Total Knee Arthroplasty?

William W. Schairer BA, Thomas P. Vail MD, Kevin J. Bozic MD, MBA

Total knee arthroplasty (TKA) and related interventions such as revision TKA and the treatment of infected TKAs are commonly performed procedures. Hospital readmission rates are used to measure hospital performance, but risk factors (both medical and surgical) for readmission after TKA, revision TKA, and treatment for the infected TKA have not been well characterized.

Targeted Use of Vancomycin as Perioperative Prophylaxis Reduces Periprosthetic Joint Infection in Revision TKA

Catherine Liu MD, Anthony Kakis DPM, CIC, Amy Nichols RN, MBA, CIC, Michael D. Ries MD, Thomas P. Vail MD, Kevin J. Bozic MD, MBA

The role of vancomycin in surgical antimicrobial prophylaxis and high-risk patients who are most likely to benefit remains unclear.

Statistical Considerations in the Psychometric Validation of Outcome Measures

Alla Sikorskii PhD, Philip C. Noble PhD

The evaluation of the outcomes of total knee arthroplasty requires measurement tools that are valid, reliable, and responsive to change. However, the accuracy of any outcome measurement is determined by the validity and reliability of the instrument used. To ensure this accuracy, it is imperative that each instrument used in orthopaedics is free of biases leading to inaccurate estimates of treatment effects.
