Figure 1.

Visual patterns of single-photon emission computed tomography/computed tomography (SPECT/CT) and postoperative symptom improvement. a, b. Representative SPECT/CT images of the anterior- and posterior-dominant pattern of uptake in the medial tibial plateau. c. The group with anterior-dominant patterns tended to show better outcomes in terms of changes in the postoperative knee injury and osteoarthritis outcome score, although without statistical significance. The visual analogue scale did not show any noticeable correlation with the uptake pattern.
