Abstract
Background
Fracture dislocation of the knee involves disruption of two or more knee ligaments with associated tibial plateau fracture. If these injuries are not evaluated swiftly, can result in a limb-threatening injury. The aim of this study is to look at the clinical outcomes of a single surgeon case series at a major trauma centre.
Methods
Prospectively collected data was analysed for a 5-year period. Primary outcome measures used were International Knee Documented Committee(IKDC) score and Knee Injury & Osteoarthritis Outcome Score(KOOS). The secondary outcome measures include Tegner activity scale, knee range of movements & complications.
Results
23 patients were presented with the mean age was 37 years(17–74). 14% of patients sustained vascular injury & 19% had common peroneal nerve injury. Priority was given for early total repair/reconstruction with fracture fixation within 3 weeks where feasible (90% of patients), and if not, a staged approach was adopted. The mean IKDC score was 67 & KOOS was 73. The mean postoperative Tegner Activity Scale was 3.6 with mean flexion of 115(90–130). We observed some patterns of tibial plateau fractures are associated with similar patterns of ligamentous injuries. The anterio-medial rim fractures (52%) were associated with PCL, ACL & avulsion injuries of posterio-lateral corner structures. Most of the neurovascular injuries happened in this group. The other recognisable pattern was posterio-medial fractures, which were associated with ACL avulsion injury.
Conclusion
To our knowledge, this is the first kind of study to report some fracture patterns that can be associated with particular ligamentous injuries.
