Abstract : Multiple ligament injuries of the knee joint involve at least 2 of the 4 major ligaments, with an occurrence
of 0.001% to 0.013%.
The mechanism of injury for the two most common knee dislocation patterns, anterior and posterior,
are reasonably well described. Rotatory dislocations are less common. Various mechanism described
by Keneddy et al. are hyperextension, dashboard injury, varus or valgus/rotation, flexion/adduction and
rotation around the posterolateral corner.
We report a case of multiple ligament injury following anteromedial dislocation of knee after long jump. In
our knowledge, we did not find any literature or case report supporting long jump as mechanism of injury.
Patient was taken for single stage arthroscopic ACL and PCL reconstruction and open LCL reconstruction
using autologous multiple ipsilateral hamstring grafts. Standard rehabilitation protocol was followed in post
operative period. At present, she is walking without assistance and able to perform her daily and routine
activities, clinically she is having mild anteroposterior ligaments laxity probably due PCL failure, with full
knee range of motion but not involved in sports activities.
