- * Mean (SD), † median (quartiles), ‡ mean (range), BMI; body mass index.
- ACL reconstruction: hamstring tendons graft, n = 23, patellar tendon graft, n = 1.
- The Tegner Activity Scale, ranges from 0 to 10, least to hardest strenuous activity for the knee. A Tegner activity level of 2 is equal to recreational sports such as golf, cycling and swimming, an activity level of 4 is equal to recreational sports such as jogging, aerobics, or cross-country skiing and a Tegner activity level of 6 is equal to recreational sports such as tennis or badminton and competitive sports such as orienteering.
