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

ABSTRACT:

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.

Purpose

(1) To compare JSW measurements using 2 established measurement techniques in healthy control participants and (2) to determine whether the mean JSW of the uninjured contralateral knee in a cohort with anterior cruciate ligament (ACL) reconstruction is different from that obtained from a true control population.

Study design

Cohort study (diagnosis); Level of evidence, 2.

Methods

Medial and lateral
