In 119 active young adults with acute ACL injury, no major differences regarding frequency of structural tissue damage (incident cartilage damage, bone marrow lesions, and osteophytes) were observed on MRI scans obtained 2 and 5 years after injury regardless of whether the injury was treated with early or delayed ACL reconstruction or rehabilitation alone.
The rehabilitation-alone group had less inflammation at 2- and 5-year follow-up compared with both postsurgical groups.
a,
Baseline MRI scan. b, At 2 years, there are osteophytes at lateral femur and tibia (arrows) and subtle incident superficial cartilage damage at the femur (arrowhead). Early ACL reconstruction was performed. c, At 5 years, there is slight increase in osteophyte size (arrows).
