Posterolateral corner reconstruction using hamstrings grafts—A comparative biomechanical study of three techniques

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare three posterolateral corner (PLC) reconstruction techniques—the popliteofibular loop (PFLoop), the modified LaPrade (LP) and modified Arciero (AR) techniques—in restoring knee laxity in varus (VR), external tibial rotation (ER) and posterior tibial translation (PTT). Methods Nine cadaveric knees were subjected to 8Nm VR, 5Nm

Increased radiolucency on conventional radiographs around tibial components does not imply more load‐induced displacement of a total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose After total knee arthroplasty (TKA), radiolucent lines on routine conventional radiographs are commonly interpreted as impaired tibial component fixation, although their relation to implant motion remains unclear. This necessitates a comparison with measured component displacement.

No clinical and functional benefit after medial congruent compared to ultra congruent total knee arthroplasty at 1 year: A prospective randomized controlled study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Various conforming bearing designs are used during total knee arthroplasty (TKA), yet their impact on clinical outcomes remains uncertain. In recent years, the use of medial congruent (MC) and ultra congruent (UC) onlays has gained popularity.

A biomechanical investigation comparing a novel bone cement bridging screw system with conventional treatment methods for Kummell’s disease

Scientific Reports
Based on the characteristics of Kummell’s disease (KD) and related anatomical structures of the thoracolumbar spine, a novel bone cement screw system has been designed to effectively avoid the cement loosening and displacement.

Sagittal femoral morphology is not associated with robotic planning or soft‐tissue balance during robotic‐assisted total knee arthroplasty: An analysis from the Brescia Knee Research Group

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate the influence of sagittal femoral morphology on robotic planning parameters and intraoperative soft‐tissue balance in robotic‐assisted total knee arthroplasty (TKA). It was hypothesised that sagittal femoral morphology has limited impact on intraoperative planning and laxity.

Femoral component internal rotation in functionally aligned robotic‐assisted total knee arthroplasty does not impair functional outcomes

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Femoral component internal rotation tightens the medial flexion gap and medialises femoral trochlea position, thus influencing patellofemoral tracking and function. Therefore, one of the tenets of mechanically aligned total knee arthroplasty (TKA) has been to avoid femoral component internal rotation relative to the transepicondylar ...

Biomechanical changes of different cement volumes at the thoracolumbar vertebrae in osteoporotic compression fractures: a finite element analysis

BMC Musculoskeletal Disorders
Objective The aim of this study is to investigate the biomechanical changes in the sandwich vertebrae (SV), fractured vertebrae, and adjacent vertebrae at the thoracolumbar vertebrae in patients with osteoporotic vertebral compression fracture (OVCF) who

Posterior tibial slope is linearly related to anteroposterior shift of the tibiofemoral contact mechanics: A biomechanical study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate the changes in tibiofemoral contact mechanics following an infra‐tubercle slope‐modifying osteotomy. Methods An infra‐tubercle slope‐modifying osteotomy was performed on eight fresh‐frozen cadaveric knees and fixed with an external fixator, which allowed for accurate slope adjustments from 15° to 0° in 5° increments. The

Knee joint line obliquity alters lateral meniscal root tension, tibiofemoral subluxation and compartment‐specific contact pressures

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The objective was to measure effects of joint line obliquity (JLO) on meniscus posterior root tension, tibiofemoral subluxation and contact pressures. It was hypothesised that a medial JLO would increase medial meniscal (MM) root tension, medial tibiofemoral subluxation and medial compartment contact pressure, and vice versa for ...
