Abstract: Objective To evaluate the clinical significance of tunnel view X-ray of the knee joint in the diagnosis of knee osteoarthritis. Methods A total of 220 patients with knee osteoarthritis (276 knee joints)received tunnel view X-ray and conventional anteroposterior,anteriolateral and patellar axial radiograph of the knee. Imaging characteristics of knee osteoarthritis were statistically compared between two techniques.Results The quantity of intercondylar fossal osteophyte (77.9% vs.40.6%), tibial spine osteophyte (79.0% vs. 64.9%),exterior and interior femoral hyperosteogeny (84.1%vs 75.3%)and loose body of in-tercondylar fossa (1 1.6%vs. 4.3%)significantly differed between two imaging methods (all P<0.05 ),sug-gesting the evident superiority of tunnel view X-ray. Compared with tunnel view X-ray,conventional anteropos-terior,anteriolateral and patellar axial radiograph possessed significant advantages in revealing the quantity of cystic lesion below articular surface,loose body within articular cavity and hyperosteogeny of the upper and low-er margins of patella (all P<0.05 ).The findings of knee joint stenosis were consistent between two techniques (P>0.05 ). Conclusion Based upon conventional radiograph,tunnel view X-ray probably contributes to the adjuvant diagnosis of knee osteoarthritis.
