Image-Free Robotic-Assisted Total Knee Arthroplasty Improves Implant Alignment Accuracy: A Cadaveric Study.

Background: Improving resection accuracy and eliminating outliers in total knee arthroplasty (TKA) is important to improving patient outcomes regardless of alignment philosophy. Robotic-assisted surgical systems improve resection accuracy and reproducibility compared to conventional instrumentation. Some systems require preoperative imaging while others rely on intraoperative anatomic landmarks.

What is the Effect of Posterior Osteophytes on Flexion and Extension Gaps in Total Knee Arthroplasty? A Cadaveric Study.

Background: Posterior compartment knee osteophytes may pose a challenge in achieving soft-tissue balance during total knee arthroplasty (TKA). Obtaining symmetry of flexion and extension gaps involves balance of both bony and soft-tissue structures. We hypothesize that space-occupying posteromedial femoral osteophytes affect soft-tissue balance.

Risk factors for postpolypectomy bleeding in patients receiving anticoagulation or antiplatelet medications.

Background And Aims: Balancing the risks for thromboembolism and postpolypectomy bleeding in patients requiring anticoagulation and antiplatelet agents is challenging. We investigated the incidence and risk factors for postpolypectomy bleeding on anticoagulation, including heparin bridge and other antithrombotic therapy.

Methods: We performed a retrospective cohort and case control study at 2 tertiary-care medical centers from 2004 to 2012.

[Surgery of labio-maxillo-palatal clefts during humanitarian mission in the Philippines].

After describing the Philippines and the Comité de Soutien Enfance Philippines, a humanitarian association with a three-fold objective: to build, to educate and to treat, the authors present the organization and practical conduct of their missions abroad which have enabled them to treat almost 400 patients with cleft lip and palate between the ages of 3 months and 46 years.

Differentiation of Alzheimer and cerebrovascular patients with the Minnesota Percepto-Diagnostic Test--Revised.

60 adult patients with focal cerebrovascular accidents (30 with left cerebral hemisphere lesions, 30 with right cerebral lesions) and 30 adults with Alzheimer disease were compared to 30 normal adults on the Minnesota Percepto-Diagnostic Test--Revised (MPD--R). The regular scoring variables plus the two-step method of diagnosis for brain damage with the MPD--R were used. One-way analyses of variance with age and mental status as covariates yielded a significant difference between control subjects and brain-damaged patients on most of the MPD--R variables.
