Tibiales Malalignment bei Mobile-Bearing-Prothesen
… the critical angle of tibial (varus / valgus) malalignment of knee prostheses in vitro, a simulator investigation was performed. Mobile-bearing- prostheses were implanted in a simulator with 1°-30 valgus- and varus malalignment as well as in neutral position. More extreme malalignment caused …

Effects of Chiropractic Adjustment on Malalignment of Posture and Lumbosacral Complex Pain
… the effects of chiropractic adjustments on malalignment of the posture and lumbosacral complex pain. About fifty billion dollars a year was spent on treatment of lower back pain in about 80% of the population.<sup>1</sup> Athletes at Bridgewater State University were used as participant in …

Finite element analysis of total knee replacement considering gait cycle load and malalignment
… has investigated the influence of gait cycle, malalignment and overweight on total knee replacements using a finite element method. Dynamic and finite element models of fixed- and mobile-bearing implants have been created and solved; the fixed- and mobile-bearing implants demonstrated different …

The Influence of Frontal and Axial Plane Deformities on Contact Mechanics during Squatting: A Finite Element Study
… cause of disability worldwide. Lower limb malalignment was a risky factor leading to KOA, altering the load distributions. This study aimed to study the influence of knee deformities on knee contact mechanics and knee kinematics during squatting. A full-leg squat FE model was developed …

Development of a Human Tibiofemoral Joint Finite Element Model to Investigate the Effects of Obesity and Knee Malalignment on Joint Contact Pressure
… gait to decrease joint contact forces. Knee malalignment has been identified as a strong mediating factor between obesity and knee OA progression. Excess body weight acting on a varus malaligned knee would have an additive effect on cartilage stress and could cause stress levels to exceed the …

BIOMECHANICS OF THE DISTAL RADIOULNAR JOINT WITH A MALALIGNED DISTAL RADIUS
… (DRUJ) before and after simulated distal radius malalignment would provide important new information to the treatment of these fractures. Furthermore, an investigation into the effect of soft- tissues would further the biomechanical understanding of these disorders. In light of the foregoing, a …

Musculoskeletal Conformation of the Normal and Diseased Canine Stifle With Emphasis on Patella Luxation and Cranial Cruciate Ligament Deficiency
… to CCL deficiency than tibial torsion and malalignment of the patellar ligament. The results support the concept that a muscle imbalance, specifically predominance of the gastrocnemius muscle, may oppose the cranial tibial thrust and predispose Labrador Retrievers to CCL disease.

Intramedullary nailing of tibial non-unions using the suprapatellar approach: a case series
… knee extended, which facilitates correction of malalignment in the sagittal and coronal planes. The aim of our study was to review the outcome of diaphyseal tibia non-unions, treated with an intramedullary nail, using the suprapatellar approach. Method: We retrospectively reviewed consecutive …

Further development of a non-invasive infra-red (IR) system in clinical assessment of knee laxity in healthy volunteers
… One of the main contributing factors to this is malalignment of the tibial and femoral components. The incorporation of computer-assisted orthopaedic surgery (CAOS) into this procedure has produced better alignment, and better functional scores post-intervention. Recently, a non-invasive …

The mechanics of patello-femoral joint dysfunction: the usefulness of the Q-angle
… dominant theory of its aetiology is „patellar malalignment?, in which the vastus medialis oblique (VMO) muscle is ineffective in controlling patellar position but this is based on assumption. The Q-angle, a frontal plane measure, indicates patellar position relative to the pelvis and tibia; …

Meniscectomy & osteoarthritis
… were observed where the PFJ was <5mm.<br/>Malalignment was greater in those knees that underwent medial meniscectomy as opposed to either lateral or medial & lateral meniscectomies. Malalignment demonstrated correlation with ROM and TFJ OA.<br/>Serum and synovial fluid was processed and …

The Biomechanics of Sit-to-Stand and Physical Performance in Patellofemoral Osteoarthritis
… or the FFW. These results indicate that dynamic malalignment of the TF joint is present during STS in persons with PFOA. This may contribute to the increased pain and decreased function in persons with PFOA.

4D CT based analysis of knee kinematics
… range of motion, postoperative instability and malalignment still hinder the restoration of the knee's original function. Bearing in mind that stability, range of motion and alignment are all directly correlated with the kinematics of the knee, then focus should be given to understanding the …

Osteoarthritis. Epidemiologic and genetic aspects.
… of body weight on the risk for OA. For example malalignment has an additive effect of body weight on the development of knee OA. The effect may to an extent be purely mechanical, i.e. the increased weight putting more strain on the joint, but it has also been shown that cytokines originating …
