Small deviations between planned and performed bone cuts using a CT-based robotic-arm-assisted total knee arthroplasty system.

Purpose: Computed tomography (CT)-based robotic system for total knee arthroplasty (TKA) has shown improved accuracy compared to conventional. This study was designed to (1) confirm the accuracy of the robotic system in achieving the plan and (2) establish the alignment and positioning deviation between final components and planning, by measuring the discrepancy between final implant alignment and the corresponding planned cut.

Methods: Ninety-six cementless robotic-arm assisted (RA) TKAs were assessed.

Image-based robotic-arm assisted unicompartmental knee arthroplasty provides high survival and good-to-excellent clinical outcomes at minimum 10 years follow-up.

Purpose: The purpose of the present study was to determine the incidence of revision and report on clinical outcomes at a minimum of 10 years follow-up in patients who had received a medial unicompartmental knee arthroplasty (UKA) with an three-dimensional image-based robotic system.

Methods: A total of 239 patients (247 knees), who underwent medial robotic-arm assisted (RA)-UKA at a single center between April 2011 and June 2013, were assessed. The mean age at surgery was 67.

Management and Outcomes of Tibial Eminence Fractures in the Pediatric Population: A Systematic Review.

Background: Tibial eminence fractures (TEF) of Meyers-McKeever type II-III-IV usually require surgical management. No consensus in the literature has been achieved regarding the best treatment option. The aims of the present systematic review were (1) to analyze the current literature and describe the outcomes of surgical treatment for TEF; and (2) to compare the outcomes of different surgical options using arthroscopic reduction and internal fixation (ARIF) with sutures or screws and open reduction and internal fixation (ORIF).

Total knee arthroplasty in-vivo kinematics changes after insert replacement for posterior cruciate ligament deficiency: a case report.

In cruciate-retaining (CR) total knee arthroplasty (TKA) the preservation of the posterior cruciate ligament (PCL) provides joint stability and drives knee kinematics. No previous studies described in-vivo knee kinematics of PCL-deficient CR TKA. In the present case report it's described the in-vivo kinematic pattern change in a patient with post-operative PCL failure before and after insert replacement to a cruciate substituting (CS) design.

[The sentinel lymph node biopsy. Evolution and convalidation of the technique].

Background: Sentinel node biopsy is a minimally invasive technique alternative to routine axillary dissection in breast cancer staging. This technique selects women with positive nodes who may benefit from axillary dissection, avoiding unnecessary operations in negative node biopsies.

Aims: In this article we report a 5 year multi disciplinary experience in sentinel node biopsy involving the General Surgery Unit of Imola Hospital in collaboration with Radiologist, Pathologists and Specialists in Nuclear Medicine.
