Case:
A 35-year-old man with morbid obesity sustained an ultra-low velocity (ULV) rotational knee dislocation secondary to a fall from standing. The patient was successfully treated using a subcutaneous knee-spanning internal fixator, the “INFIX” technique, which has previously been described for pelvic ring injuries.
Conclusion:
This novel technique maintained the stable reduction of an ULV knee dislocation in a patient with morbid obesity until adequate healing was achieved.
