Sex Differences in Factors Influencing Recovery from Arthroscopic Knee Surgery

Patricia H. Rosenberger PhD, Firdaus S. Dhabhar PhD, Elissa Epel PhD, Peter Jokl MD, Jeannette R. Ickovics PhD

Many factors affect recovery from arthroscopic partial meniscectomy, including patient sex. However, sex differences in time to maximal recovery of knee function and factors influencing differential rates of recovery are unknown.

Incidence and Reasons for Nonrevision Reoperation After Total Knee Arthroplasty

Benjamin Zmistowski BS, Camilo Restrepo MD, Lauren K. Kahl BS, Javad Parvizi MD, FRCS, Peter F. Sharkey MD

A dramatic increase in the demand for TKA is expected. The current burden of revision TKA is well known but the incidence and etiology of nonrevision reoperations after primary TKA is not.

Wear Damage in Mobile-bearing TKA is as Severe as That in Fixed-bearing TKA

Natalie H. Kelly BS, Rose H. Fu BS, Timothy M. Wright PhD, Douglas E. Padgett MD

Mobile-bearing TKAs reportedly have no clinical superiority over fixed-bearing TKAs, but a potential benefit is improved polyethylene wear behavior.

What is the Evidence for Total Knee Arthroplasty in Young Patients?: A Systematic Review of the Literature

James A. Keeney MD, Selena Eunice OTR, MS, Gail Pashos BS, Rick W. Wright MD, John C. Clohisy MD

TKA is commonly performed to treat advanced inflammatory and degenerative knee arthritis. With increasing use in younger patients, it is important to define the best practices to enhance clinical performance and implant longevity.

Popliteus Tendon Resection During Total Knee Arthroplasty: An Observational Report

Thomas J. Kesman MD, MBA, Kenton R. Kaufman PhD, Robert T. Trousdale MD

The contribution provided by the popliteus tendon in patients undergoing TKA is poorly defined. Some authors believe the popliteus tendon is essential to a well-functioning arthroplasty, while others do not believe it provides a critical function.

Liner Exchange and Bone Grafting: Rare Option to Treat Wear & Lysis of Stable TKAs

John J. Callaghan MD, Eric R. Reynolds, Nicholas T. Ting BA, Devon D. Goetz MD, John C. Clohisy MD, William J. Maloney MD

Liner exchange and bone grafting are commonly performed for wear and osteolysis around well-fixed modular acetabular components that otherwise would require structural allografting and revision THA. However, liner exchange in the face of substantial lysis around TKA has been performed rarely with reports of failure rates of up to 25% at 3 year followup.

In Vivo Normal Knee Kinematics: Is Ethnicity or Gender an Influencing Factor?

Filip Leszko MSc, Kristen R. Hovinga MS, Amy L. Lerner PhD, Richard D. Komistek PhD, Mohamed R. Mahfouz PhD

In vivo studies have suggested Caucasians achieve lower average knee flexion than non-Western populations. Some previous studies have also suggested gender may influence condylar AP translation and axial rotation, while others report an absence of such an influence.

Technical Challenges of Total Knee Arthroplasty in Skeletal Dysplasia

Raymond H. Kim MD, Giles R. Scuderi MD, Douglas A. Dennis MD, Steven W. Nakano BA

Total knee arthroplasty (TKA) in patients with skeletal dysplasias is particularly challenging as a result of the anatomic variances and substantial bony deformities. Little has been written regarding technical considerations that should be made when performing TKA in skeletal dysplasia.

Implant Design Influences Tibial Post Wear Damage in Posterior-stabilized Knees

Mark M. Dolan MD, Natalie H. Kelly BS, Joseph T. Nguyen MPH, Timothy M. Wright PhD, Steven B. Haas MD

The tibial post in posterior-stabilized total knees is a potential source of polyethylene wear debris, but the relationship between the shape and location of the tibial post in relation to the tibiofemoral bearing surfaces and the subsequent wear damage patterns remains unknown.

Hematologic Genetic Testing in High-risk Patients Before Knee Arthroplasty: A Pilot Study

Hany Bedair MD, Martin Berli MD, Sefer Gezer MD, Joshua J. Jacobs MD, Craig J. Della Valle MD

Patients with a personal or familial history of thromboembolism are considered at higher risk for thromboembolic disease after knee arthroplasty. While it remains unclear why some patients develop deep vein thrombosis (DVT) or pulmonary embolism (PE) despite similar operative procedures and the same prophylactic regimen, we presume one explanation would be genetic predisposition.
