In November 2008, Chavonne Freeman, 53, was stopped in traffic on westbound 144th Place at LaGrange Park in Orland Park, Illinois, when her car was rear-ended by a U.S. Postal Service vehicle. Freeman was taken from the scene to the emergency room at Palos Community Hospital. She complained of neck and back pain. She followed up with her primary care physician two days later with complaints of neck, back and knee pain.
Six weeks after the crash, Dec. 29, 2008, Freeman was seen by an orthopedic surgeon; she complained of knee pain. She was diagnosed with patellar subluxation (partial dislocation) and instability in the left knee. Surgery was recommended for January 2009 and was performed on July 29, 2009.
Three weeks later, on Aug. 19, 2009, Freeman died from a pulmonary embolism caused by a deep vein thrombosis resulting from the knee surgery. No medical negligence was alleged in the lawsuit filed by her family.
