The Influence of Preimplant Balancing on Manipulation under Anesthesia Rates following Imageless Robotic-Assisted Total Knee Arthroplasty.

Acquired idiopathic stiffness (AIS) following total knee arthroplasty (TKA) often requires manipulation under anesthesia (MUA). Robotic-assisted TKA (RA-TKA) systems provide gap balance templates for objective correlation with the rate of AIS. The purpose of this study was to assess intraoperative balancing parameters that were associated with MUA utilizing an "anatomical" implant design.

Safe Sex After Total Hip Arthroplasty: Using Computed Tomography-Based Robotics to Evaluate "At-Risk" Sexual Positions.

Background: Total hip arthroplasty (THA) can improve sexual satisfaction, but fear of dislocation can lead to sexual difficulties following this procedure. Previous kinematic research identified 4 sexual positions in women and 2 in men that were considered at risk for impingement. This study aimed to validate these findings using current robotic THA simulations.

Comparing dislocation rates by approach following elective primary dual mobility total hip arthroplasty: a systematic review.

Background: Dual mobility components can be implanted during total hip arthroplasty (THA) for primary osteoarthritis via a direct anterior approach (DAA), anterolateral approach (ALA), direct lateral approach (DLA), or posterior/posterolateral approach (PLA). This review compares dual mobility hip dislocation rates using these approaches for elective primary THA.

Methods: PubMed, Embase, and Cochrane databases were systematically searched for articles published after January 1, 2006 that reported dislocation rates for adult patients after primary THA with dual mobility implants.

Survivability of the Femoral Neck System for the treatment of femoral neck fractures in adults.

Introduction: Hip fractures are common injuries in the elderly, with an incidence that continues to rise. The femoral neck system (FNS) recently emerged as a novel treatment option for femoral neck fractures, but long-term survivability of the implant remains uncertain. The purpose of this study is to evaluate survivability of the FNS and assess risk factors for implant failure.

Can Component Size in Total Knee Arthroplasty Be Predicted Preoperatively?-An Analysis of Patient Characteristics.

Accurately predicting component sizing in total knee arthroplasty (TKA) can ensure appropriate implants are readily available, avoiding complications from malsizing while also reducing cost by improving workflow efficiency through a reduction in instrumentation. This study investigated the utility of demographic variables to reliably predict TKA component sizes. A retrospective chart review of 337 patients undergoing primary TKA was performed.
