Frequency of knee cartilage loss.
| Variables | Whole Joint, n = 163.0 | Medial TF*, n = 149.4 | Lateral TF*, n = 151.5 | PF*, n = 156.4 |
|---|---|---|---|---|
| No quadriceps weakness | 16.7 (11.7) | 9.0 (6.9) | 4.9 (3.7) | 6.3 (4.5) |
| Quadriceps weakness | 8.6 (44.0) | 5.0 (28.4) | 2.4 (13.7) | 2.0 (11.8) |
| Total cohort | 25.3 (15.5) | 14.0 (9.4) | 7.3 (4.8) | 8.3 (5.3) |
Values are weighted n (%).
↵* N depends on the number able to progress in the given compartment. TF: tibiofemoral; PF: patellofemoral.
