  • Data are presented as adjusted mean estimate with 95% CI in brackets.

  • *Adjusted for surgeon.

  • †The Knee Osteoarthritis Outcome Score ranges from 0 to 100, with higher scores indicating less pain and knee symptoms, less problems with ADL and sport and a better QoL.

  • ‡The NRS for pain ranges from 0 to 10, with higher scores indicating more pain.

  • §The Lysholm score ranges from 0 to 100, with higher scores indicating less knee symptoms and higher levels of functioning.

  • ¶The WOMET normalised score ranges from 0 to 100, with higher scores indicating a higher health-related quality of life.

  • **The Tegner scores ranges from 0 to 10, with higher scores indicating a higher activity level.

  • ††Satisfaction with knee function is measured using a visual analogue scale ranging from 0 to 100, with higher scores indicating a higher patients’ satisfaction with their knee function.

  • ADL, activities of daily living; NRS, Numeric Rating Scale; QoL, quality of life; WOMET, Western Ontario Meniscal Evaluation Tool .
