Does Malrotation of the Tibial and Femoral Components Compromise Function in Kinematically Aligned Total Knee Arthroplasty?
Internal and external malrotation of the femoral and tibial components is associated with poor function after total knee arthroplasty (TKA). We determined the degree of malrotation for both components in…
The Utility of Increased Constraint in Primary Total Knee Arthroplasty for Obese Patients
Total knee arthroplasty (TKA) for obese patient entails more preoperative comorbidities and complications, and shorter longevity. This article is a retrospective review comparing longevity of the constrained implant with a…
One-Stage Revision for Infected Total Hip Arthroplasty
Prosthetic joint infection (PJI) is a challenging complication following total hip arthroplasty (THA). Two-stage exchange arthroplasty is preferred for treating chronic PJI of THA, although specialized centers have reported comparable…
Robotically Assisted Unicompartmental Knee Arthroplasty with a Handheld Image-Free Sculpting Tool
Although unicompartmental knee arthroplasty may pose a lower risk of perioperative complications and achieve better functional outcomes than total knee arthroplasty, a high degree of accuracy of implant positioning and…
Diagnosis of Periprosthetic Infection
The diagnosis of periprosthetic joint infection (PJI) has been performed by obtaining a history and physical examination, blood tests, and analysis of the synovial fluid and tissue samples. The measurement…
Innovations in Intraoperative Tumor Visualization
