Multiligament knee injuries and Gait analysis
By David Parker (1), Thomas Neri (2) in category UPDATE
Multiligament knee injuries (MLKI) involve injuries to a combination of at least 2 of the 4 major ligaments; anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL) and/or postero-lateral corner (PLC) injuries. MLKI are relatively rare with an incidence of 0.01-0.013% per year, but are potentially limb-threatening injuries[1,2]. There are various mechanisms for injury: high speed injuries, most commonly in motor-cross sports, lower speed sports injuries, and less commonly but well recognised, knee dislocations may be associated with overload in the super obese. Irrespective of the mechanism, patients present with varying patterns of ligamentous disruption and often have significant associated injuries. These complex injuries most often require extensive surgical and rehabilitative intervention. The nature of MLKI is underpinned by substantial heterogeneity with regard to demographics, injury pattern and recovery potential in the typical patient cohort. Consequently, MLKI are difficult to study and their management is still challenging. For each MLKI patient, orthopaedic surgeons have to answer several questions: What is the best timing of surgery? How to decide between repair and reconstruction techniques? Which...
