Increased patellofemoral pressure after TKA: an in vitro study
TLDR
Despite correct implantation of the patellar implants and largely unchanged patellofemoral offset, a highly significant increase in pressure after patellr resurfacing was measured, and the preservation of the native patella seems reasonable if there is no higher grade patellAR cartilage damage.
In Vitro Simulation of Stance Phase Gait Part I: Model Verification
TLDR
An in vitro simulator was developed to reproduce the kinematics and kinetics of stance phase gait on cadaver foot specimens and was found to be in good general agreement with some exceptions which include a slightly more lateral gait line.
Biomechanical Properties of Commonly Used Autogenous Transplants in the Surgical Treatment of Chronic Lateral Ankle Instability
TLDR
The application of a transplant with low biomechanical stability, such as the periostal flap, requires more postoperative immobilization as in a strong orthosis or cast, because of the need for surgical stabilization of chronic lateral ankle instability.
Influence of bi- and tri-compartmental knee arthroplasty on the kinematics of the knee joint
TLDR
BKA with intact cruciate ligaments resembles rotation and translation of the natural knee during a simulated weight-bearing flexion and is a suitable treatment option for medial and patellofemoral osteoarthritis with advantages in rotational characteristics compared to TKA.
Forces in anterior cruciate ligament during simulated weight-bearing flexion with anterior and internal rotational tibial load.
TLDR
Data indicate that, in a weight-bearing knee flexion, ACL provides substantial resistance to the externally applied ATF but not to the ITT, which is consistent with previous work on anterior cruciate ligament forces.
Translational and rotational knee joint stability in anterior and posterior cruciate-retaining knee arthroplasty.
TLDR
The findings suggest that, provided functional ligamentous structures, bicruciate-retaining BKA is a biomechanically attractive treatment for joint degenerative disease.
Hindfoot Motion after Isolated and Combined Arthrodeses: Measurements in Anatomic Specimens
TLDR
It is concluded that the talonavicular joint is the key articulation for hindfoot motion and fusion of the calcaneocuboid joint had no significant influence on remaining hind foot motion.
The treatment of hallux valgus.
TLDR
The clinical outcome of present treatments seems to be good in most cases, but large-scale randomized trials are still needed to verify the efficacy of the wide variety of operations and fixation techniques that are currently being offered.
[Intra-articular fracture of the calcaneus. Classification, assessment and surgical procedures].
TLDR
The experience with open reduction of calcaneus fractures and internal stabilization without joint transfixation indicates that the operative treatment principles can be recommended for patients who are either professionally active or active in sports.
