Passive dynamic walking with knees : a point foot model
… a hybrid model for a passive 2D walker with knees and point feet is presented. The step cycle of the model has two phases of continuous dynamics: one with an unlocked knee configuration and a second one with a locked knee configuration. These stages are modeled as three-link and two-link …

Clinical investigation of the functional outcome of fixed bearing versus mobile bearing knees
Total Knee Arthroplasty is a high-volume and high-cost procedure, with persisting limitations to patient satisfaction. Prosthesis designs aim to restore function whilst providing stability, without joint constraint. This double-blinded randomised controlled trial is the first of its kind where the …

Characterizing Bone Turnover in Osteoarthritic Bone Marrow Lesions in Human Knees Using Tetracycline Histology
Bone marrow lesions (BMLs) are a hallmark sign of osteoarthritis (OA) associated with clinical symptoms of pain and pain progression. Based on previous literature, BMLs are likely centers of increased bone remodeling. Currently, there is no consensus as to what defines a BML outside of its …

The biomechanics of knees at high flexion angles before and after Total Knee Arthroplasty
… However, many patients rarely can flex tier knees beyond 120⁰ after TKA. Limited information is available regarding the biomechanics of the knee beyond 120⁰ of flexion. Little is known about the biomechanical function of the posterior cruciate ligament in cruciate retaining TKA designs and …

COMPARISON OF EXTERNAL TIBIAL ROTATION IN AFFECTED AND UNAFFECTED KNEES AS MEASURED BY TWO CLINICAL METHODS
… tibial rotation, could distinguish between knees affected or unaffected by pathology and/or surgery. METHODS: Twenty-eight subjects with knee pathology diagnosed by a physician and with self-reported activity limitations were tested on one occasion using both methods. With subjects in …

Weak at the Knees: Wearable Haptic Feedback Device for Real-Time Gait Retraining for Slowing Knee Osteoarthritis
Real-time gait retraining has been shown to be a promising non-invasive intervention for patients with early stage medial compartmental knee osteoarthritis. In order for real-time gait retraining to be effective beyond a clinical and laboratory setting, the technology needs to be effective but also …

Growth Of Bald Cypress Boles And Knees As Influenced By Precipitation And Inundation At Sardis Lake, Mississippi
… of bald cypress (Taxodium distichum) boles and knees in response to inundation and precipitation over small (< 4 m) elevation gradients was examined by measuring interannual growth increments of boles and knees at five sites at Sardis Lake, Mississippi. There was a significant (p=0.019) growth …

Heads, shoulders, knees and toes: Exploring bodies, body parts and personhood in late Neolithic Malta through funerary taphonomy
This research addresses the body and personhood in late Neolithic Malta (c. 3600–2300 cal BC) by reconstructing funerary practices at two collective burial sites: the Xemxija Tombs (Malta) and Xagħra Circle (Gozo). The range and sequence of funerary practices are identified through implementing …

Prospective Clinical Study of Posterior Cruciate and Meniscofemoral Ligaments of the Knee Joint From Surgical Biopsies and Morphometric Analysis From Thiel Embalmed Knees
… procedure proper for painfree or painful knees during surgery. Preoperative parameters predict degeneration of the PCL and MFLs, and therefore can be used to determine TKA procedure. The current study aimed to evaluate the detailed macroscopic and microscopic degenerative changes within …

Parameters related to the equinus ankle in ambulatory children with cerebral palsy : an investigation of the differences between children with the diplegic and hemiplegic subtypes
… diplegia have been reported to have crouched knees (knee in flexion deformity) and an equinovalgus, while children with hemiplegia tend to have genu recurvatum (over extended knees), ankle equinovarus and a shorter affected limb (AL) than the unaffected limb (UL). No study has specifically …
