title: Assessment of the responsibility between a road traffic accident and medical defects after the traffic accident injury of knee joint.
abstract: A 48-year-old Chinese woman was hit by a car in a road traffic accident. Local county hospital considered that her right knee was injured, but didn't find any sign of fracture from X-ray imaging. Then the hospital gave diagnosis of soft tissue contusion and the patient started to exercise with burden 21 days after her right lower limb was fixed by plaster slab. Four months later, she had to go back to the county hospital for recheck due to persistent pain on her right knee. Then, the right tibia outer plateau fracture was found. The patient rejected the advice of open reduction and internal fixation of right tibia plateau fracture. Instead, she accepted the unicompartmental knee arthroplasty in a hospital affiliated to a medical college. The patient felt the knee pain alleviated after surgery However, the joint dysfunction was aggravated even more. The patient used the legal procedure for personal compensation. Both driver and the insurance company disputed that the final consequence of the injured knee was due to not only the traffic accident, but also poor medical practice involved. Therefore the court consigned us to make judicial judgment of expertise. After investigation, we found the earliest X-ray graph after the accident had shown the fracture of right tibia outer plateau and right knee valgum, with articular surface involvement, and the traffic accident was considered as the primary cause of sequelae. At the same time, the county hospital missed the diagnosis of fracture, and led to insufficient fixation of right lower limb, which was not good for rehabilitation from fracture and joint injury. This was the secondary cause of sequelae. Additionally, instead of the standard therapy, the affiliated hospital of medical college made the unicompartmental knee arthroplasty four months later, which also had a little defect. It was the minor reason for the result.
