  • Data are presented as mean with SD in brackets unless otherwise reported.

  • Some values of the arthroscopic partial meniscectomy group are known for 47 patients instead of 48.

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

  • †The IKDC score ranges from 0 to 100, with higher scores indicating less symptoms and a higher patient’s perception of knee function and ability to participate in sports activities.

  • ‡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.
