A video summary is available with the new study by Birkenes et al. in JBJS:
This study from Norway aimed to (1) evaluate the long-term cumulative risk of knee arthroplasty after arthroscopic identification of focal cartilage lesions in the knee, (2) investigate the risk factors for subsequent knee arthroplasty, and (3) estimate the subsequent cumulative risk of knee arthroplasty compared with that in the general population.
Play the video summary:
As concluded by the authors, “we found that the 20-year cumulative risk of knee arthroplasty after a focal cartilage lesion in the knee was 19%. Deep lesions, higher age at the time of cartilage surgery, high BMI at the time of follow-up, ACI [autologous chondrocyte implantation], and >1 cartilage lesion were associated with a higher risk of knee arthroplasty.”
