Comparison of Arthroscopic Evaluation Results between the Two Groups
| Characteristic | MA group (n=26) | WA group (n=26) | p-value |
|---|---|---|---|
| AM synovial coverage, no. (%) | |||
| Grade A | 22 (85) | 14 (54) | |
| Grade B | 4 (15) | 10 (38) | |
| Grade C | 0 (0) | 2 (8) | |
| Synovial coverage score, mean±SD | 2.8±0.4 | 2.4±0.7 | 0.03a) |
| PL synovial coverage, no. (%) | |||
| Grade A | 18 (69) | 13 (50) | |
| Grade B | 6 (23) | 10 (38) | |
| Grade C | 2 (8) | 3 (12) | |
| Synovial coverage score, mean±SD | 2.5±0.7 | 2.3±0.7 | 0.51 |
Synovial coverage score was evaluated on a 3-point scale: grade A, 3 points; grade B, 2 points; and grade C, 1 point.
MA: minimal ablation, WA: wide ablation, AM: anteromedial, SD: standard deviation, PL: posterolateral.
