On Dec. 26, 2008, plaintiff Nathan Cartwright, 30, a car salesman, was operating his Jeep Cherokee on northbound 170th Street when he came to a four way stop sign at the intersection with East Palmdale Boulevard in Palmdale. As he proceeded to make a left turn onto Palmdale Boulevard, his vehicle was broadsided by a Lincoln Navigator operated by Michael Zaku, who was traveling behind Cartwright and trying to pass him by driving on the wrong side of the road. Cartwright claimed a knee injury from the accident. Cartwright sued Zaku and the owners of Zaku’s vehicle, Ashraf Adel Zaky and Lois Zaky. He alleged that Zaku was negligent in the operation of his vehicle and that his parents, Mr. and Mrs. Zaky, were vicariously liable for their son’s actions. Zaku ultimately admitted liability., Cartwright claimed he injured his left knee in the accident. He sustained a torn medial meniscus and ultimately underwent arthroscopic surgery on Oct. 7, 2009. Cartwright claimed that he still suffers pain to his left knee. He alleged that as a result, he may require another arthroscopic surgical procedure, followed by post-surgical rehabilitation. Thus, Cartwright sought recovery of $555,000 in total damages, including $89,417.50 for his past medical costs. Defense counsel disputed the causation, nature and extent of Cartwright’s . Counsel argued that Cartwright’s were due to a subsequent incident, which occurred several months after the motor vehicle accident when Cartwright fell at Universal CityWalk Hollywood in Los Angeles. Cartwright responded that he fell as a result of the knee injury he sustained in the subject automobile accident.
