A failure mechanism of Leeds-Keio ligaments
Abstract:
From our experience with the Leeds-Keio artificial ligament at Bolton Hospitals we report the histology from three cases in which the new ligament was demonstrated to have failed in response to trivial injury, after an initially successful anterior cruciate replacement. The histology showed fragmentation of graft material associated with a chronic inflammatory response in the new ligament. A chronic inflammatory response occurs as a result of fragmentation of the Dacron fibres; and once established, inhibits production of the neoligament, thus dooming it to failure.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...
