An Evaluation of Anatomic Referencing for Femoral Component Sizing Using Computed Tomography-Based Computer Modeling J. Knee Surg. (IF 1.7) Pub Date : 2024-02-27 Brett Campbell, Max Weinberg, Jeffrey Bischoff, Giles R. Scuderi
One of the critical steps in total knee arthroplasty is femoral component positioning and sizing. Historically, there was wider variability between femoral component sizes, necessitating the concepts of anterior referencing (AR) and posterior referencing (PR). With the introduction of smaller increments between sizes, the concept of anatomic referencing has been introduced to replace AR and PR. The

Achieving Correct Balance in Total Knee Arthroplasty with Fixed Varus Deformity J. Knee Surg. (IF 1.7) Pub Date : 2023-10-30 Kara Sarrel, Maxwell Weinberg, Giles Scuderi
Varus knee deformity is one of the most common deformities presenting for total knee arthroplasty (TKA). When present, a varus knee deformity contributes to overload of the medial joint compartment during gait, leading to increased medial compartment forces as well as lateral soft tissue lengthening. Additionally, a fixed varus deformity is associated with medial soft tissue contractures of the deep

Objective Clinical Measurement Tools for Functional Evaluation of the Surgical Patient J. Knee Surg. (IF 1.7) Pub Date : 2023-08-10 Jacob Thomas, Jamie B. Hall, Rose Schauffler, Trent M. Guess
Following knee surgery, clinicians have traditionally used visually rated or time-based assessments of lower extremity movement quality to measure surgical outcomes, plan rehabilitation interventions, and measure success. These methods of assessment are prone to error and do not fully capture a patient's inefficient movement patterns post surgery. Further, currently available systems which objectively

More Is Not Merrier: Increasing Numbers of All-Inside Implants Do Not Correlate with Higher Odds of Revision Surgery J. Knee Surg. (IF 1.7) Pub Date : 2023-07-18 James D. Oosten, Alex C. DiBartola, Jonathan C. Wright, Parker A. Cavendish, Eric M. Milliron, Robert A. Magnussen, Robert A. Duerr, Christopher C. Kaeding, David C. Flanigan
The purpose of this study was to evaluate the relationship between the number of all-inside meniscal repair implants placed and the risk of repair failure. We hypothesized that the use of higher numbers of all-inside meniscus repair implants would be associated with increased failure risk. A retrospective chart review identified 351 patients who underwent all-inside meniscus repair between 2006 and

Can the ACL Cross-Sectional Area Be Predicted? Size Correlation and Proportion between the ACL Cross-Sectional Area and the Femoral Intercondylar Notch Area J. Knee Surg. (IF 1.7) Pub Date : 2023-07-12 Takanori Iriuchishima, Bunsei Goto
The purpose of this study was to reveal the correlation and proportion between the anterior cruciate ligament (ACL) cross-sectional area and the femoral intercondylar notch area. Sixty-three subjects (33 female and 30 male) less than 50 years old were included in this study. All subjects complained of knee pain, although magnetic resonance imaging (MRI) showed no structural damage of the knee. Using

Evaluating the Role and Impact of Health Literacy for Patients Undergoing Knee Surgery J. Knee Surg. (IF 1.7) Pub Date : 2023-07-10 Samuel D. Gieg, James P. Stannard, James L. Cook
Health literacy is defined as “the capacity to obtain, process, and understand basic medical information and services and the competence to use such information and services to enhance health.” Much of the research regarding health literacy in orthopaedic surgery has focused on readability of educational materials. However, the role of health literacy in patient-reported outcomes is somewhat unknown

Increase in the Posterior Tibial Slope Provides Better Joint Awareness and Patient Satisfaction in Cruciate-Retaining Total Knee Arthroplasty J. Knee Surg. (IF 1.7) Pub Date : 2023-07-03 Hiroyasu Ogawa, Masaya Sengoku, Yutaka Nakamura, Tetsuya Shimokawa, Kazuichiro Ohnishi, Haruhiko Akiyama
The effect of the posterior tibial slope (PTS) in cruciate-retaining total knee arthroplasty (CR-TKA) on clinical outcomes remains unclear. We aimed to investigate (1) the effect of alteration of the PTS on clinical outcomes, including patient satisfaction and joint awareness, and (2) the relationship between the patient-reported outcomes, the PTS, and compartment loading. Based on the alteration of

Practice Changes Induced by a Traveling Fellowship J. Knee Surg. (IF 1.7) Pub Date : 2023-07-03 Ian Hollyer, Akaila C. Cabell, Stephen T. Duncan, Stefano M. P. Rossi, Peter K. Sculco, C Lowry Barnes, Derek F. Amanatullah
The John N. Insall Knee Society Traveling Fellowship selects four international arthroplasty or sports fellowship-trained orthopaedic surgeons to spend 1 month traveling to various Knee Society members' joint replacement and knee surgery centers in North America. The fellowship aims to foster research and education and shares ideas among fellows and Knee Society members. The role of such traveling

Total Knee Conversion Rates and Functional Outcome After Calcium Phosphate Injection for Bone Marrow Lesions of the Knee J. Knee Surg. (IF 1.7) Pub Date : 2023-06-20 Alex Stratton, Malcolm Wanless, Nicholas Abidi
Untreated osteoarthritis (OA)-related bone marrow lesions (OA-BML) can hasten the progression of knee OA. Previous studies have shown that fluoroscopically guided intraosseous calcium-phosphate (CaP) injections of OA-BML during knee arthroscopy can lead to pain reduction, improved functionality, and prolonged time until conversion to total knee arthroplasty (TKA). The purpose of this retrospective
