An Uncommon Trauma: Hoffa's Fracture Associated with Tibial Avulsion Fracture of the Posterior Cruciate Ligament

Abstract

BackgroundSince Hoffa fractures are usually the result of high-energy injuries, many additional accompanying injuries have been described. This is the first paper representing the lateral condyle Hoffa fracture accompanying tibial avulsion fracture of the posterior cruciate ligament (PCL).Case PresentationA 42-years-old male presented with swelling and instability in his left knee after falling during parachute landing. He was diagnosed with simultaneous Letenneur Type I lateral condyle Hoffa fracture and tibial avulsion fracture of the PCL. He was operated on with a single posterior incision for both fractures. Multiple cannulated lag screws were used for the fixation of the Hoffa fracture, and a buttress plate was used for additional stability. PCL avulsion fracture was fixed with a cannulated screw with a washer. The patient was allowed for full-weight-bearing and range of motion at the sixth week after the operation. No complications occurred during follow-up.ConclusionCare should be taken in terms of additional injuries that may accompany Hoffa fractures. The posterior approach allows easy access to both fractures with a single incision. Using a buttress plate after the fixation of the Hoffa fracture with multiple lag screws provides additional stability.
