Combined Reconstruction of the Medial Patellofemoral Ligament and the Medial Quadriceps Tendon–Femoral Ligament Using Rectus Femoris Tendon Autograft

Arthroscopy Techniques, EarlyView.
Abstract Patellofemoral instability remains a challenging condition, especially in skeletally immature patients, who are at increased risk of recurrence. The medial patellofemoral ligament has historically been the focus of surgical reconstruction; however, recent anatomic studies have also highlighted the medial quadriceps tendon–femoral ligament as ...

A normalisation procedure for biaxial bias extension tests [PDF]

, 2008
Biaxial Bias Extension tests have been performed on a plain-weave carbon fibre engineering fabric. The test results have been normalised using both the upper and lower bound method proposed by Potluri et al.

Retention or sacrifice of posterior cruciate ligament has no effect on in vitro kinematics in medial pivot total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The role of the posterior cruciate ligament remains debated, particularly in medial pivot designs intended to functionally substitute the posterior cruciate ligament. While some manufacturers recommend posterior cruciate ligament resection, evidence regarding its biomechanical relevance in medial pivot total knee arthroplasty is ...

Rectus femoris tendon morphometry and practical landmarks for harvesting: A cadaveric study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To perform a qualitative and quantitative cadaveric analysis of the rectus femoris (RF) tendon to determine its suitability as a standalone autograft for knee ligament reconstruction and to identify consistent anatomical landmarks for safe and reproducible harvest.

CLASS‐MRI validates patient‐specific ACL footprints across variable fluoroscopic C‐arm positioning: A cadaveric study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The aim of this study was (1) to investigate the accuracy of identifying the femoral and tibial anterior cruciate ligament (ACL) footprints (FPs) using the Compressed Lateral and Anteroposterior Anatomical Systematic Sequences (CLASS) method compared to the to the gold standard (anatomical dissection with direct FP marking, referred to

Identification of anisotropic properties of polymer sheets from heterogeneous biaxial tests

Polymer Testing, 2022
The stretch blowing process for PET bottle induces the anisotropic mechanical properties due to the different elongation of macromolecular chains. For example, the Young's modulus can be multiplied by almost two in the longitudinal direction and more ...

Acceleration of Phase‐Modulated Ultrashort Echo Time Sequence for Fast T2 and Adiabatic T1ρ Mapping of the Knee Joints

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and validate an accelerated phase‐modulated ultrashort echo time (PM‐UTE) sequence for volumetric T2 and adiabatic T1ρ (AdiabT1ρ) mapping of both short‐ and long‐T2 tissues in the knee joint. Methods The proposed method estimates and removes the T1‐dependent component from a single reference acquisition, eliminating repeated
