  • Elimination criteria p≤0.10.

  • Stepwise elimination of blocks of independent variables: previous meniscus surgery (p=0.926), other findings at arthroscopy (p=0.353), meniscal pathology (p=0.157), cartilage pathology (p=0.308).

  • Individual R2 values may not add up to total R2 due to rounding.

  • ADL, function in daily living; BMI, body mass index; KOOS, Knee Injury and Osteoarthritis Outcome Score.
