Embolic popliteal venous aneurysm revealing a congenital venous anatomical variation: A case report and literature review.

Venous aneurysms of the lower limbs are rare, and those located in the popliteal area are the most described. Congenital anatomical variations have been reported but are also exceptional. They can affect both superficial and deep veins.

Morphological and histological features of thicker cartilage at the posterior medial femoral condyle in advanced knee osteoarthritis.

Objective: To assess morphological and histological features of cartilage at the posterior medial condyle in advanced pre-prosthetic osteoarthritis (OA), which is notably thicker compared to non-OA knees.

Design: Cartilage thickness was measured pre-operatively using MRI in 10 subjects with medial femorotibial OA (mean age: 70.2 years).

Intra- and inter-operator reliability of three-dimensional preoperative planning in total knee arthroplasty.

Purpose: To characterize the intra- and inter-operator reliability of a CT-based 3D preoperative planning software.

Materials And Methods: This study analyzed 30 CT scans of de-identified knees with osteoarthritis. For each scan, a case planner segmented the bones and pre-planned the TKA.

Simultaneous Evaluation of Bone Cut and Implant Placement Accuracy in Robotic-Assisted Total Knee Arthroplasty.

This study aimed to evaluate the accuracy of bone cuts and implant placements, simultaneously, for total knee arthroplasty (TKA) performed using a system with an active robotic arm. Two experienced orthopaedic surgeons performed TKA on ten cadaveric legs. Computed tomography scans were performed to compare the bone cuts and implant placements with the preoperative planning.

Slowing gait during turning: how volition of modifying walking speed affects the gait pattern in healthy adults.

Background: Turning during walking and volitionally modulating walking speed introduces complexity to gait and has been minimally explored.

Research Question: How do the spatiotemporal parameters vary between young adults walking at a normal speed and a slower speed while making 90°, 180°, and 360° turns?

Methods: In a laboratory setting, the spatiotemporal parameters of 10 young adults were documented as they made turns at 90°, 180°, and 360°. A generalized linear model was utilized to determine the effect of both walking speed and turning amplitude.
