Table 2.
Mean change in Lysholm score and Knee Injury and Osteoarthritis Outcome Score from preoperative to follow-up, and mean difference in change over time between the MF group and OAT mosaicplasty group
| MF | OAT Mosaicplasty | MF vs OAT mosaicplasty | p value | |
|---|---|---|---|---|
| Change over time | Change over time | Change over time | ||
| Mean (95 % CI) | Mean (95 % CI) | Mean difference (95 % CI) | ||
| Lysholm | 21.6 (3.7–39.4) | 13.4 (0.9–25.8) | 8.2 (−11.7 to 28.1) | n.s |
| KOOS Pain | 20.6 (2.8–38.3) | 11.8 (−2.8 to 26.4) | 8.8 (−12.7 to 30.3) | n.s |
| KOOS Symptoms | 17.4 (2.6–32.2) | 8.5 (−3.5 to 20.6) | 8.9 (−8.9 to 26.7) | n.s |
| KOOS ADL | 13.0 (−3.8 to 29.8) | 7.5 (−4.3 to 19.3) | 5.5 (−13.4 to 24.4) | n.s |
| KOOS Sport/Rec | 32.4 (13.3–51.6) | 41.3 (23.7–58.9) | −8.9 (−33.4 to 15.7) | n.s |
| KOOS QoL | 34.6 (15.1–54.0) | 25.0 (10.6–39.3) | 9.6 (−12.7 to 31.9) | n.s |
Change over time = follow-up minus preoperative
Mean difference = mean change over time in MF group minus mean change over time in OAT mosaicplasty group
