Abstract

Purpose: To evaluate the accuracy of single photon emission computed tomography (SPECT) compared with arthroscopy in the diagnosis of acute knee pain due to meniscal tear. Methods: Patients with knee pain that persisted for less than six months with normal plain radiographs that had arthroscopic surgery following SPECT scan were included. The main scintigraphic criterion for diagnosing a tear of the meniscus was tibial plateau activity on the planar image with at least a half crescent of peripheral tibial plateau uptake. The accuracy of SPECT in detecting meniscal tears was calculated according to the arthroscopic findings as the gold standard. Results: There were 68 patients in the study (46 males and 22 females). The mean age was 45.3 (17-72) years and the mean time between SPECT scan and surgery was 3.5 (1-6) months. The overall sensitivity of SPECT was 90%, specificity 70%, NPV 54%, PPV 95% and accuracy 87%. Conclusion: SPECT was found to be an accurate imaging technique in the diagnosis of symptomatic meniscal tears in patients with acute knee pain and unremarkable plain radiographs. Thus, SPECT may be helpful in selecting candidates for arthroscopy.
