We performed a prospective, randomised trial of 44 patients to compare the functional outcomes of a posterior-cruciate-ligament-retaining and posterior-cruciate-ligament-substituting total knee arthroplasty, and to gain a better understanding of the in vivo kinematic behaviour of both devices. At follow-up at five years, no statistically significant differences were found in the clinical outcom...

Elbow instability often results in chronic overuse injuries, especially with overhead throwing in athletes. Initial management of medial collateral ligament (MCL) injuries often is conservative, but surgery may be required. In several studies, nearly half of throwing athletes with MCL injuries who were treated conservatively were able to return to their previous level of competition. Surgical t...

INTRODUCTION Sprained ankle is a very common injury in children. Proper treatment of ligament injuries enables full recovery. X-ray and US examinations are commonly available diagnostic methods. MATERIAL AND METHODS Two hundred and six children (113 girls and 93 boys, mean age 10.6) with recent ankle joint sprain (up to 7 days of injury) were subject to a retrospective analysis. All patients ...

This paper investigates the effect of muscle contraction on lower extremity injuries in car-pedestrian lateral impacts. Three variables, viz. height of impact, pedestrian offset with respect to car centre and impact speed, have been considered here. Full scale carpedestrian FE simulations have been performed using the full body pedestrian model with active lower extremities (PMALE) and front st...

Materials and Methods A case review was performed for 18 consecutive patients who presented with multiligamentous knee injuries. These patients were managed over a 34-month period from 2010 to 2013 by the senior author who managed majority of the cases in our centre. Our institution is a 1300-bed Level 1 trauma centre that manages the highest number of trauma patients in our locality.3 A multil...

The defi nition of Lisfranc’s joint is the articulation between the bases of the metatarsals and the cuneiforms medially and the cuboid laterally. Unlike the lesser metatarsals, the fi rst and second metatarsals are not anchored to each other with an intermetatarsal ligament; rather, they are connected indirectly via Lisfranc’s ligament. Lisfranc’s ligament connects the lateral aspect of the me...

Enneking et al. examined the process of local spread of primary bone and soft tissue tumors of the extremities and proposed a “surgical staging system” and “the concept of compartment and anatomic barriers.”17 Applying this concept to the spine, we studied the histology of 19 vertebral tumor specimens resected by TES. We found that the following tissues served as barriers to spinal tumor progre...

A motion-based Inverse Kinematics Knee (IKK) model was developed for Total Knee Replacement (TKR) joints. By tracking a sequence of passive knee motion, the IKK model estimated ligament properties such as insertion locations. The formulation of the IKK model embedded a Forward Kinematics Knee (FKK) model in a numerical optimization algorithm known as the Unscented Kalman Filter. Simulation resu...

OBJECTIVES Digital infrared thermographic imaging (DITI) has been used widely for various inflammatory diseases, circulatory diseases, skin diseases, musculoskeletal diseases and cancers. In cases of ligament injury, obviously the temperature of the damaged area increases due to local inflammation; however, whether the temperature also increases due to DITI has not been determined. The purpose ...
