The most clinically significant risk factors for development of DVT’s are age over 70 and previous history of DVT (Goodman and Snyder pg 312). Other high risk factors include patients who have undergone major general surgery, major orthopedic surgery, or major trauma. PDVT has been reported to be the most common complication following hip or knee arthroplasty and traumatic orthopedic injuries (Riddle and Wells 2004). Below is a list of risk factors collaborated from Goodman & Snyder and Riddle & Wells.
