Vascular Injuries After Total Joint Arthroplasty

Vascular injuries, although highly feared, can occur after total joint arthroplasty, often resulting in legal suits. This study evaluates the circumstances related to vascular injuries after joint arthroplasty. Using prospectively collected data on 13 517 patients undergoing total joint arthroplasty at our institution, 16 (0.1%) vascular injuries were identified. Eleven injuries occurred after total knee arthroplasty (TKA) and 5 after total hip arthroplasty (THA). Indirect injury was the most common mechanism in TKA. In contrast, direct injury was most prevalent in THA. One patient died of complications related to vascular injury. Of 16 patients, 8 (50%) had launched a legal suit against the operating surgeon. There appears to be no further specific measure that can be taken to absolutely avoid this complication. Patient awareness regarding this real problem may play a role in defraying the high likelihood of legal suits associated with this complication.
