A significant proportion knee injuries in skeletally mature patients were associated with high-energy acetabular fractures, according to results of this retrospective cohort study.
Researchers identified 1,273 skeletally mature patients treated for acetabular fractures at level 1 and level 2 trauma centers between November 2004 and December 2013. Researchers analyzed acetabular fractures with knee injuries regarding the type of acetabular fracture, mechanism of injury, energy of injury, pattern of the knee injury and knee examination findings at initial presentation, intraoperatively and at follow-up. They also analyzed the requirement for either surgery or conservative management and associated injuries, as well as clinical data entered during inpatient stay and office visits. Main outcome measures included the incidence and pattern of knee injury.
Within a 1-year period from the date of injury, results showed 15% of patients had ipsilateral knee symptoms. Researchers noted 29% of patterns of knee injury were fractures, 25% were ligamentous lesions and 46% were miscellaneous causes, including bone bruises, wounds and swelling. When looking at associated injuries, researchers found 45% of patients had ipsilateral hip dislocation, 31% had pelvic injuries, 32% had extremity injuries, 20% had head injuries, 20% had chest injuries, 12% had abdominal and genitourinary injuries and 4% had injuries of the spine. – by Casey Tingle
