*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.
