How Subtalar Kinematics Affects Knee Laxity in Soccer Players After Anterior Cruciate Ligament Injury?

Purpose The goal of the current study was to ascertain whether there is an association between foot pronation and anterior cruciate ligament (ACL) injury in a group of elite professional soccer players. Methods Two groups of soccer players were studied, all of whom played in the Greek Super League. The ACL group included players who had suffered an ACL injury in the last 2 years. The non-ACL group was composed of players who had never suffered an ACL injury. We used a 3D baropodometric laser scanner to measure pronation or overpronation (navicular drop phenomenon) of the subtalar joint and how this affects the subtalar joint while standing. We assessed ACL laxity using the Genourob Rotab. Results ACL-injured patients, regardless of the mechanism of injury, exhibited greater navicular drop values than a randomly selected group of subjects with no history of ACL injury. Conclusion Greater knee joint laxity and subtalar pronation may be associated with an increased risk of ACL injury. Pronation of the foot appears to be a risk factor for ACL injury. These findings should be integrated into future studies to better define how neuromuscular control related to lower extremity biomechanics is associated with ACL injury.

Synovial sarcoma of the anterior tibialis tendon.

We report the clinical features, radiographic findings, management and results of a patient with a post-traumatic synovial sarcoma of the anterior tibialis tendon. Our patient was managed operatively and with radiotherapy with good clinical results. No evidence of recurrence or metastatic disease was seen at 3-year follow-up.

Total hip replacement for acute femoral neck fracture: a survey of National Joint Registries.

Joint registers audit the performance of different types of prosthesis. The data from these registers is invaluable, as the conclusions are evidence based and are not based on the results from a small clinical trial or a case series. The 3rd National Joint Registry Annual Clinical Report (2005) of England and Wales was compared with the latest available online report of other national joint registers, particularly with reference to the usage of total hip replacement performed for fracture of the neck of the femur. In Sweden, total hip replacement is performed for the management of a fracture of the neck of the femur six times more often than in England and Wales, four times more often than in Australia, twice more often than in Canada. Hip fracture registers could provide us with the much needed clinical evidence that could help us solve the last controversy of this unsolved fracture.
