This article considers the establishment, purpose and conduct of knee arthroplasty registers using the Swedish register as an example. The methods of collection of appropriate data, the cost, and the ways in which this information may be used are considered.

Traumatic knee dislocation is a serious and potentially limb threatening injury that can be easily missed if meticulous history and examination have not been employed. Neurovascular injuries are common in this condition, and due diligence should be given to their thorough evaluation at time of secondary survey so as to avoid complications such as ischaemia, compartment syndrome and eventual amp...

A 24 year old West Indian woman was admitted as an emergency having suffered an injury to the right knee on landing awkwardly on a trampoline. She was a reasonably experienced club trampoliner and on admission there was an obvious dislocation of the right knee joint. The peripheral pulses were absent in the right foot and capillary return was sluggish. The anterior dislocation (Figs. 1 and 2) w...

An association between lateral patellar dislocation (LPD) and medial collateral ligament injury (MCL) has recently been demonstrated on MRI. The same valgus injury that disrupts the femoral MCL insertion can also cause a simultaneous MPFL tear at its femoral insertion, due to the close anatomical relationship of both ligamentous structures. Valgus laxity due to MCL-deficiency increases the Q-an...

In the present report, we describe a 3-year-old girl who presented with the full clinical and radiographic features of Larsen syndrome. The knee deformity in our patient was compatible with a complete (grade 3) anterior dislocation of the tibia on the femur. The reduction of knee dislocations in Larsen syndrome patients should be completed before treatment of the hips because 45 ̊ of knee flexio...

Bilateral knee dislocations seldom occur, and fewer than a dozen cases of bilateral luxatio erecta humeri (erect dislocation of the shoulder) have been reported. Here we present the case of a patient who sustained bilateral knee dislocations and bilateral luxatio erecta humeri in a motorcycle accident. Transient neurologic compromise resolved with closed reduction of the bilateral shoulder and ...
