Correlations between osteophyte grades and joint space narrowing grades in local compartment and the other compartment. Spearman's rank correlation coefficients (rs) are shown
| Joint space narrowing | ||||
|---|---|---|---|---|
| Site of osteophyte | Lateral TFJ | Medial TFJ | Lateral PFJ | Medial PFJ |
| TFJ, tibiofemoral joint; PFJ, patellofemoral joint. | ||||
