Comparison of 2 Radiographic Techniques for Measurement of Tibiofemoral Joint Space Width

摘要

Background:No consensus is available regarding the best method for measuring tibiofemoral joint space width (JSW) on radiographs to quantify joint changes after injury. Studies that track articular cartilage thickness after injury frequently use patients’ uninjured contralateral knees as controls, although the literature supporting this comparison is limited.
