An anteroposterior radiograph oftheleg to include the hip and ankle, taken with the patient standing, provides an estimate ofthe line ofload-bearing at the knee. Gait analysis may be used to determine the way in which the load in the knee is shared between the medial and lateral compartments during normal walking. A comparison ofthe results from the two methods, carried out on a group of47 patients, led to the conclusion that both calculations are required for the successful outcome of a tibial osteotomy or a total arthroplasty.
