Complications in simultaneous bilateral total knee arthroplasty, is it a safe procedure?

Background: There is controversy regarding various aspects of simultaneous bilateral total knee replacement (SBTKR). We found disparity in the postoperative outcomes and complications associated with the procedure in the literature linked with the topic.

Objective: To retrospectively analyze the need for blood transfusion after surgery and complications associated with total knee replacement according to the type of procedure (SBTKR or unilateral).

Anterior Center-Edge Angle Is Less Reliable Than Anterior Wall Index to Predict Anterior Coverage of the Femoral Head.

Background: No consensus is available regarding which radiographic measurement most accurately correlates with anterior coverage of the femoral head.

Purpose: (1) To determine the correlation between 2 measurements of anterior wall coverage: total anterior coverage (TAC) calculated from radiographs and equatorial anterior acetabular sector angle (eAASA) calculated from computed tomography (CT) scans; (2) to define the correlation between anterior center-edge angle (ACEA) and anterior wall index (AWI) with TAC and eAASA; and (3) to investigate what other radiographic metrics may help predict anterior coverage.

Study Design: Cohort study (Diagnosis); Level of evidence, 3.

Subtalar arthroereisis in pediatric flexible flat foot: Functional and radiographic results with 5 years of average follow-up.

The aim of this retrospective study is to evaluate the clinical-functional and radiographic results in pediatric patients with painful and disabling Flexible Flat Foot (FFF) refractory to conservative treatment who underwent percutaneous subtalar arthroereisis with a Maxwell Brancheau Arthroereisis® (MBA) implant. Patients aged 8-14 years old with a minimum follow-up of 24 months were included. A pre and postoperative radiographic evaluation was carried out analyzing Meary's angle, internal Moreau-Costa-Bartani´s angle, Talar declination angle, Calcaneal Pitch, Kite's angle, Talar-1st metatarsal angle, and Talonavicular coverage angle.

Cemented versus uncemented reverse shoulder arthroplasty for acute proximal humeral fractures.

Background: The purposes of this study were (1) to compare postoperative range of motion (ROM) and functional outcomes in patients with proximal humeral fractures operated on with cemented or uncemented reverse shoulder arthroplasty (RSA), (2) to compare the rate of tuberosity healing between cemented and uncemented stems, (3) to determine whether there are significant differences in functional outcomes between patients with healed tuberosities and those with unhealed tuberosities, and (4) to compare complications and revision rates in patients with cemented RSA and uncemented RSA.

Methods: A cemented RSA was performed early in the study period, which represented a historical cohort (January 2015 to January 2017), followed by a transition to the uncemented RSA later in the study period (February 2017 to February 2019). We excluded 22 cases from postoperative evaluation because of fracture sequelae, age < 65 years, death, and institutionalization; 3 patients were lost to follow-up.

Who Restores Hip Biomechanics More Effectively after a Femoral Neck Fracture? Comparison of Total Hip Arthroplasties Performed by Either Hip Surgeons or Orthopaedic Residents.

Background: This study aims to analyze the ability to restore hip biomechanics in patients who undergo total hip arthroplasty for displaced femoral neck fractures operated by either hip surgeons (HSs) or orthopaedic residents (ORs).

Methods: We retrospectively compared 95 patients treated by HSs (group A) with 110 patients treated by ORs (group B). Leg-length discrepancy, femoral offset (FO), center of rotation (COR), acetabular inclination, and acetabular anteversion were evaluated on postoperative radiographs using the healthy contralateral hip as control.
