Single-photon emission computed tomography-computed tomography (SPECT-CT) is a highly sensitive tool for detecting bone metabolism. We determined whether subchondral bone metabolism, as indicated by SPECT-CT in the patellofemoral (PF) joint, predicts response to conservative management in middle-aged patients with chronic anterior knee pain (AKP), and whether SPECT-CT results correlate with arthroscopic assessments of chondral lesions in the PF joint. |
