  Today's Top Story Study: Differences Caused by Knee Scooter Flexion Knee position when using a scooter device may be linked to venous stasis, according to a comparative study published online in Foot & Ankle International. Thirteen healthy participants were included in the study. Researchers assessed comparative measurements while participants were standing and using the knee scooter. Standing versus using the scooter device was associated with a significant decrease in mean velocity (6.5 cm/s versus 3.2 cm/s) and [...]

  Today's Top Story Study: Factors Associated with Postoperative PROMs in TKA Patients A study published in the September issue of The Journal of Arthroplasty found a correlation between kinematic factors and postoperative patient-reported outcome measures (PROMs) in total knee arthroplasty (TKA) patients. Researchers simulated deep knee bend kinematics for 96 postoperative TKA patients and measured the Knee Injury and Osteoarthritis Outcome Score (KOOS) 12 months postoperation. They observed significant nonlinear relationships between these scores and rollback and [...]

  Today's Top Story Study Analyzes Effect of Implant Orientation on Knee Implant Performance A study published in the September issue of The Journal of Arthroplasty found that total knee arthroplasty (TKA) position and orientation may impact polyethylene damage and how the knee performs postoperation. Researchers compared three-dimensional CT measurements of prerevision TKA positioning with postrevision retrieval analysis for 30 TKA implants and calculated differences in thickness between medial and lateral components. Varus angulations were tied to thinner [...]

  Today's Top Story Study Compares Orthopaedic Specialty Hospital to Tertiary Referral Center for Shoulder Arthroplasty An orthopaedic specialty hospital (OSH) may be more efficient than a tertiary referral center (TRC) for shoulder arthroplasty, according to a study published online in the Journal of Shoulder and Elbow Surgery. Researchers assessed 136 shoulder arthroplasties each from an OSH and TRC between 2013 and 2015 and recorded anesthesia preparation time (APT) (patient in room to skin incision), surgical time (ST) [...]

  Today's Top Story Study Identifies Risk Factors for Increased Pain Following Knee Surgery In a cross-sectional study published online in Knee Surgery, Sports Traumatology, Arthroscopy, young age, low body weight, and smoking were associated with higher pain and the need for rescue medication after arthroscopic knee surgery. The study included 57 patients with a median age of 39 years. The most significant association was observed in younger patients and smokers; increased length of surgery was also correlated [...]
